[@yuuzyerbrejn9603]

When Rex Beisel designed the Corsair they used the inverted gull wing to provide for shortening the landing gear while still maintaining prop clearance. Then they found that they had gained a measure of aerodynamic relief by having the junction of the wing be 90 degrees to the angle of the fuselage side, thus enhancing the speed. Seems to me that any superprop being designed today would make use of that knowledge, as you did. Nice aircraft!

[@princesofthepower3690]

Not really there are other more effective ways of enhancing speed without utilising inverted gull wings, as gull wings tended to lack stability especially in a stall. There’s a reason all super props didn’t use gull-wings.

[@kdrapertrucker]

But hey did it in the Corsair to keep the landing gear legs shorter and stronger while giving the 18 foot prop clearance.

[@opatrick1961]

You're basically designing a gull winged P51H with a griffon engine and gull wings. The Merlin was 27L and capable of 2.200hp. The Griffon was 37L and potentially much more power. It was used with dual 3 blade props, contra rotating. If you planned to use a P47 style Turbocharger the fuselage would no doubt have to be larger. You have a great thing here, but I think it would have to look different to fit everything in. Not a bad idea here, a big V12 with a mustang style cooling setup, combined with Corsair wings, and a thunderbolt style forced induction system. It would work, but would look somewhat different. Even the griffon would require a larger nose. I still think my first sentence applies. Martin Baker MB5 comes to mind.

[@risingsun9595]

Another automation would be automatic flaps, like what the Kawanishi N1K2 had. It used a simple mercury switch that extended flaps automatically as pilots slowed down in turns to prevent the aircraft from stalling in a dogfight. It was more tempermental to fly but it could keep up with even the best of the late-war US aircraft such as the P-51, F4U, and the F6F.

[@Barstool_cub_driver]

That’s interesting. Didn’t know that.

[@MrWillNeedham]

Quite a few German aircraft, including the 109, had automatic slats that served a similar purpose. A lot of pilots disliked them, even going as far as to fix them permanently in the closed position. The main problem was that their operation wasn't always predictable or desirable. When deployed, they increased the lift but also the drag. This slowed the plane down even more, which is usually the last thing you want in a dogfight.

@@risingsun9595 I'm fully aware the N1K2 had automatic flaps rather than slats, but as I said previously - they served a similar purpose. Automatically deploying lift-enhancement devices was not a unique feature and they were in widespread combat use long before the N1K2 ever flew. The reason they weren't more popular is because speed is life in a dogfight. It's far better to preserve your energy than to turn slightly tighter but be left a sitting duck. Being able to manually override them is all well and good, but if you're having to do that more often than not then it's just extra work for the pilot.

[@BARelement]

8:28 the Spitfire, Mustang, & Bf 109 are all supercharged (either 1 stage, 2 stage, 2 speed, etc) not turbo charged. That would be the Thunderbolt, Lightnings, and a few experimental planes (it was rare in that period outside of prototype).

[@themerc123]

It was rare in fighters but way more common in bombers, turbos at the time required large cooling systems, which add weight, which matters a lot in a fighter but not so much in a bomber. That's why the p47 was completely designed around it the turbo system, and used extensive steam lining to offset the weight and parasitic drag gain from the coolers. The p38 had the fuselage space for the turbo system and was the only plane too allow the Allison engine to be competitive at high alt because America was way behind on supercharging technology, but suffered greatly from high parasitic drag, but that was offset with ridiculous horsepower and a smooth power band across all altitudes. Both turbo fighters suffered from being over weight but if those planes used a modern understanding of turbocharging they would have been untouchable at any altitude. If you're building a hindsight super-prop, turbo charging is the way too go because they make nearly full boost until they quite literally run out of air.

[@mikehawk6918]

The vast majority of ww2 fighters used superchargers, not turbochargers. Turbochargers were extremely heavy and costly to build, hence why the P-47 was the heaviest and most expensive US fighter of WW2. You also said that being lighter was always an advantage, which was maybe correct in the beginning of the war, but as the FW-190 proved, heavier planes had a much easier time diving and consequently climbing from a dive (also known as the "boom and zoom"), which made them virtually untouchable to the lighter aircraft, which could turn on a dime but simply could not follow the heavier aircraft. In fact, when the FW-190 was first introduced, the British had no answer for it, and they had to rush new clipped wing spitfires into production as a stopgap, and later rushed the typhoon fighters into production with disastrous consequences (the planes literally fell apart mid flight over the English channel). I suggest your read combat trials of spitfire vs P-47. As the pilots describe it, the spitfire could turn and gain the tail of the p-47 easily, but the p-47 could disengage and engage with boom and zoom at will, which meant the spitfire was essentially a sitting duck.

[@johntillman6068]

For survivability, you need not only armor and self-sealing gas tanks, but a radial engine. Add a gull wing to a Bearcat, and you're good to go. A land-based variant without folding wings, beefed up landing gear and tailhook would have been even lighter and faster. Four 20mms was a F8F common armament.

[@jurgenh.7980]

You do not necesarily need a radial for increased survivability. Sure. It takes away some vital systems like a water cooling bur you also add a bigger target and bigger frontal surface. Sure. It was kinda the weakness of the P51 if you wanna call it that. But it is not really s design flaw. Its more a design choice. Also. Sure. As said it gives you a bit more survivability. Bit how often will you get critical hits as a pure fighter without getting shot down. A radial gives you more advantages in a multi-role enviroment where speed is a bit less important and raw strenght and flak/light guns are more of a problem.

[@th3lunchb0x]

This is a very sleek and interesting design. The biggest doubt I have about it is the turbo. Using an unintercooled turbo set up would limit the gas quality you could use and reduce top end performance because of increased risk of knock. There is no way this thing could be intercooled the way the P47 and P38 are. The only reason the tail booms of the P-38 are so skinny is because the cockpit was located in between them. The P47 got its massive size not just from the Radial engine (which it shared with the much slimmer Corsair and Hellcat) but from all of the massive intake and exhaust plumbing from the engine to the turbo and intercooler. Also, you're aircraft features open exhaust like a supercharged inverted V-12 of a Bf-109, but with a turbo this would be impractical/impossible because you would have needed to plumb all 12 exhaust tubes down to one to feed the turbo and back to the engine bay, split into 6 pipes on each side and routed back to the front of the aircraft. This would all be easily rectified with a Two-stage supercharged Merlin the P-51D was equipped with although it would not have the advantage of the constant level of boost provided by the turbo wastegates.

Given the 36L 1800hp engine this engine is in the class of the Jumo 213 and Griffon which makes it a late 1943 or 1944 engine. The Griffon IIB did start appearing in 1942 at 1735hp restricted by a simple supercharger.

[@mfree80286]

I think you'd run into compressibility problems before anything else. Fully articulated control surfaces would be the way to go here, as well as differential spoilers to augment ailerons. Only other thing I'd do different to try out would be to straighten the wing, sweep it slightly, and get it up where the center of action for the ailerons is close to or conjugate with the longitudinal CG, and then try and get the tail surfaces neutralized so there's no adverse pitch/yaw from a high roll rate. Consider the A4 Skyhawk, blisteringly fast roll rate but if you did it's 720 degrees/second for more than two rotations you were on the bare edge of departing controlled flight from adverse pitch.

[@frostgd8040]

[@kingghidorah8106]

the side view of the p100 is amazing

[@antimatter4733]

A few more things to consider. 1. Cannon details: not all 20mm cannons are created equal. What's the cartridge size, whats the velocity, what kinds of rounds are you firing. I'd recommend a relatively high velocity, average rate of fire, using SAPHEI-T(Semi armor piercing, High explosive incindiary tracer) rounds. Personally I'd prefer a combination of 2x20mm cannons with 1x30mm cannon, all with similar ballistic properties and the ability to selectively fire the 20s, 30s or both depending on what you're engaging. This effectively gives you more time on the trigger. Intercepting a bomber? Use the all the cannons. A fighter? Just the 20s till you run out of ammo then the 30s. 2. Survivability. Commonly overlooked but a major trade off is how well you want to protect your pilot vs how much weight you're willing to add. Bulletproof glass and armored steel are heavy, but they also give pilots the confidence needed to fly into bomber fire and allow your pilots to bail out and live to fight another day. I'd also add self sealing fuel tanks with neutral gas pressure like in the IL-2 and a fire suppression suppression system to the engine. 3. General designs vs Specific designs. If you're designing a high speed, high altitude interceptor you'll have to make specific design choices vs a low altitude dogfighter. Personally I think speed and climb is more important than the ability to turn. Because you might not be able to hit the enemy, but so long as you're much faster than them and employ they right tactics they won't be able to hit you. And finally all these things add complexity. Is your plane really worth 2x the resources vs 2 standard planes?

[@michaelkolano8686]

What about having 12 .50 cals?

[@wknogl2210]

Wonder if the radiators in the wings will end up being the Achilles heel of this plane, like it is on the HE-100

[@danraymond1253]

Well the He-100 didn't have radiators, it just had cooling lines on the leading edge of the wings, and that was it's Achille's Heel. Because it is much easier and more likely to take damage along the width of the wings when you're being shot at, it would almost certainly get punctured at a higher rate. However, these radiators are very close to the fuselage, and the main coolant radiator is under the fuselage. This makes it much hard to hit. The spitfire had radiators on it's wing that were even further out than these, and it didn't seem to be a particular issue. Plus, many WWII fighters had their oil cooler in the wing roots. Others had them somewhere in the engine cowling, like the Thunderbolt and Hellcat that had them slung under the engine where they're only marginally better protected. The Fw-190 had an annular ring Infront of the radial engine for better aerodynamics, though this likely left it a little more vulnerable than other planes. So no matter where you put it, it was always pretty vulnerable. It just wouldn't be smart to put it (almost) across the entire width of the wings, like the He-100 did.

You should really change the way wheels claps closes. Now they act as a HUGE airbreaks. Landing gear produce a lot of drag as it is

[@Generic_Name_1-1]

Eh taking off and landing doesn't really matter how much drag you're producing. You could also make it so the doors close when the gear is fully extended. Plus that design could double as airbrakes like the Corsair as mentioned by the other commenter.

[@judet2992]

[@BradleyGibbs]

Have a look at the Corsair.

[@MrWillNeedham]

​@@Generic_Name_1-1 Drag matters a lot during take off and initial climb out. That's why the flaps are not extended fully and why the gear is retracted as soon as possible. Turning the wheel covers 90° would improve performance in this critical phase of flight, for no downside. Propeller aircraft already have a huge and easily controllable airbrake in the form of the propeller itself. Adjust the pitch to fully fine at low throttle and the drag increase is huge. This is why most WW2 aircraft didn't need airbrakes unless they were designed for dive bombing. Even if you did want to add an additional airbrake, you'd want to be able to control it independently from the landing gear. There's no good reason to deliberately design high-drag landing gear.

[@kdrapertrucker]

They did this for real, the reasult was the F8F Bearcat. Meant to replace the FM wildcat on smaller carriers. It ended up performing more like a Jet fighter and was used for Jet conversion in the Marine corps and U.S. navy for a few years.

[@iskandartaib]

I think you missed a few things. By 1945 a lot of the proposed designs put the engine behind the pilot a la P-39 and moved the pilot just behind the prop. This would increase visibility over the nose, especially for taxiing and landing. Tricycle gear was also catching on. Everyone was starting to think this way - Rolls Royce was designing a fighter for its Crecy engine. General Motors had its P-75. The Germans had a proposed Me-509. And if you think about it.. practically all jet fighters use this general layout to this day.

I saw that someone had already mentioned the fact that a turbo-supercharger necessarily needs to duct the engine exhaust to a turbine to drive a supercharger. Clearly the exhaust stacks of this 3D design are not collected and ducted to do that. However, there are a lot more issues with this design. There's no intercooler, nor mention of a first-stage mechanical supercharger (which P-38's V-1710 and the P-47's R-2800 engines both had in addition to the turbo-supercharger). I'm not sure where the storage for 900 rounds/510-lbs of 20mm ammunition (not including belt links) is supposed to be, but that's trivial compared to the fact that the space left for fuel tanks is very limited. And you can't just pretend that you could put a bunch of fuel in the tail end, because that would totally unbalance the aircraft's CG. It was fun little design exercise, but it's not much more realistic than Chitty Chitty Bang Bang, Gundam mechs, or Reaganomics.

Fuselage mounted cannon means that the rate of fire has to be carefully governed to reduce the risk of propellor strike - while doing away with convergance issues, it means your rate of fire may be considerably reduced.

So, in a very recent video by the Imperial War Museum they talked about the development of armament on the spitfire. From that I learnt that pilots sometimes used the machine guns to "spray rounds" and only used the cannons when they were more confident of a hit because of the slower rate of fire. Apparently four cannon Spitfires were trialled but the pilots preferred two cannons. So I guess I'm saying that assuming more cannons = better isn't necessarily correct

[@dogeness]

How do you fit a turbocharger plus its cooling accessories in that tiny fuselage? Historically, planes with turbos had to either expose the turbo to the outside air (creating very draggy installations) or the fuselage had to be huge to house extra cooling pipes (P-47). This is basically why towards the end of the war designers moved towards the 2-stage variable speed supercharger as in the F4U-5.

[@goddepersonno3782]

Hi, Aerospace student here if we're talking about an actual WW2 fighter, there are so many factors and limitations that go into building the best possible fighter. Each nation has its own context and its own requirements for what "the best fighter" looks like, and so in many ways, you physically couldn't build a better fighter for Britain during 1941 than the spitfire, or the ME-109 for the Germans in 1939. There wasn't a lot of scientific/aerodynamic knowledge you could give them that would have lead to a meaningful improvement in design here. Maybe better canopy design? They had betted correctly on high-pressure water cooling and were at the absolute cutting edge of what was possible at the time with 1940s manufacturing. I can see a lot of waste in this design that would make it unattractive to nations with smaller distances to cover. 1- it's pretty massive. Based off the engine this is at least the size of the Jug, bigger even than the corsair. The larger it is, the more drag you've got to deal with and so the less effective it could possibly be - this was chosen for America because of the massive territory their carriers had to cover in the pacific. 2- the gear is sitting further out on the wings. This requires extra structural reinforcement so the fighter can sustain landings at full MTOW, and therefore more weight (also I would recommend you get the landing gear covers to close from the fuselage side of the wings rather than from the front so you're not fighting air resistance. 3- gun in the nose section. Although Germany did this with a lot of their designs there are some major potential downsides. First - the guns have to be timed to the prop, risking prop strikes. Second - the stronger the gun the greater the vibration it's putting on the structure that supports the engine. A lot of famous nose-cannon fighters had much shorter engine life because of this. 4- your vertical stabiliser is pretty small for an aircraft of that performance level. I suspect it would suffer from directional instability IRL (yaw control is the hardest control type to model in a simulation) 5- the long wings will reduce roll rate and make the aircraft less manoeuvrable (wing loading looks like it would be fairly good however) As an energy fighter rather than a "dogfighter" some of these issues will be less important than others. Things like radio, tactics, and intelligence are also often just as - if not more important than many flight parameters. I'm sure your Monsoon would be a very competitive design, but maybe not even the best in WW2 if it was actually built and flown in 1945. A fun project nonetheless and I hope you can keep improving with your designs!

The most important factor is that the operational requirement to which the aircraft will be designed is correct, both in terms of the correct requirement for the combat it will need to undertake plus actually deliverable using the technology available at the point in time at which production is required. An example might be the Bolton-Paul Defiant - a perfectly good expression of a flawed operational requirement. As such you could view it as an excellent aircraft as it delivered on the requirement, or a terrible one as a consequence of it being the wrong operational requirement.

The design looks very sleek and undoubtedly very suitable for an interceptor. Before choosing this design as the main fighter of my air force in fictional late 1940s, I would want to know if this aircraft could cover other mission roles such as escort missions requiring long range. What is the fuel endurance like? Would the aircraft have enough fuel to not require constant monitoring of fuel levels during missions other than interceptions over friendly territory? What about suitability for multi-role capability, like carrying air-to-ground ordnance? Another aspect I would want to know is survivability. Does the aircraft feature any armour for the pilot, engine, or the cooling systems? The liquid-cooled engine is fine and many other designs use very similar solution, but an air-cooled radial would have potential for better damage tolerance. Not that I'm questioning the design choices but my fleet aviators were shouting something about a tail hooks and ditching the coolant so that you could cross vast distances over ocean even when missing a few percent of the engine... What about cost? It was mentioned that this aircraft uses a turbocharger for forced induction. How does that affect the cost of the aircraft? Is the turbocharger reliable? How does the ducting work, is there an intercooler somewhere? Could similar performance be achieved at lower cost and weight by using a multi-stage/multi-speed supercharger or a single-stage variable speed supercharger instead? What kind of flight performance does the aircraft have? What about handling characteristics? Is the aircraft easy to fly or is it prone to losing control in stalls? Are the wings more optimized for low drag with a laminar flow aerofoil design, or do they feature a more conventional aerofoil that delays flow separation and gives more forgiving flight characteristics with higher stall AoA? Three 20mm cannons on the nose is adequate armament, but I would be interested in possibility of upgrading the motor cannon to a 30mm, and possibly installing additional guns on wing roots. Especially if the aircraft's main intended role is to be an interceptor, I would want additional firepower to inflict the highest possible damage to bombers during attacks, to shorten the time the aircraft has to stay within the gunners' effective range. Alternatively, a nation I know might be interested in filling the wing leading edge with machine guns, just to make their logistics simpler because they use that particular machine gun cartridge everywhere anyway...

[@ed6091]

Hey aerospace engineering student here, great video! I liked the level of detail you put in, unfortunately you didn’t take about the wing profiles (maybe it due to software limitations). It’s a very cool design, I especially liked the Corsair-like wings because I didn’t know they improved visibility! If I may add something to improve a bit the design would be to add flaps and slats if possible (latter are very important for low speed flight envelops). Also you might want to change the wing shape (seen from above) to an elliptical shape, similar to the one on the spitfire. It’s the absolute best shape for aero efficiency and wasn’t used much because of how hard it was to build. And you could tilt (rotation from above) the vertical stabiliser a bit to counter gyroscopic effect from the torque generated by the engine.

[@reinbeers5322]

Ellyptical wings were shown in postwar testing to offer almost no advantages over a simple trapezoidal wing, which is what the Spitfire's successor, the Spiteful used. They're also stupidly expensive to make and after the Spitfire and P-47, they disappeared completely.

[@ed6091]

@@reinbeers5322 on a strictly theoretical basis an elliptical distribution is the best you can get, in reality the advantage as you pointed out is not worth it but I wanted to point that out anyways but the addition of slats and flaps is a must.

[@reinbeers5322]

@@ed6091 The issue is that once theory met reality, it didn't hold up at all. IIRC it was just 5% better in just one efficiency metric. And that was for a true ellipsis, while the spitfire didn't have one and had a fair amount of wing twist to combat the nasty tip stalls it otherwise would have. As for flaps and slats, they are essential yeah. Surprised more nations and manufacturers didn't use leading edge slats in WW2.

[@ed6091]

@@reinbeers5322 actually from the theory we expected such a small gains in efficiency. Had to look up my aerodynamics notes for this, Cd depends on the Oswald factor, inside this there’s a value that can range from 0 (elliptical) to 0.18 (triangular wing), for a rectangular wing it should be around 0.02 so almost negligible. I believe this was learnt after the experiments you mentioned (delta vs taper ratio graph)

[@wobbleduck]

Ed Heinemann once said that the best way to make an aircraft is to design it around the engine you want to use. Radials were popular during the war for a reason because they had a higher power/weight offering compared to V-12's, and some of the later R-2800's had similar superchargers to the Merlin which gave them good performance at altitude. This also meant no radiators and coolant on board to cut back on weight even more. Additionally, gun convergence will still be a factor, although not as much as wing mounted guns. Height over bore from the sights will still play into the accuracy of the guns, and there's something to be said about a wider shot pattern when you aren't using targeting computers to give you a gun solution. Nose mounted guns also severely cut back on your ability to carry ammunition which also adds complexity for the maintainers every time they need to tear into something under the cowling. But, this is purely about performance and not logistics. I'm interested to see how this design will do. I must admit though, it looks really good.

[@CyberneticArgumentCreator]

You're not describing convergence, you're describing something like windage.

[@wobbleduck]

@@CyberneticArgumentCreator windage is an environmental factor, convergence is a mechanical factor related to how the guns are mounted. Regardless if it's nose mounted or wing mounted guns, your bullets will need to be zeroed at a set distance calibrated to the sight. Which is why I brought up hight over bore being a factor with nose mounted guns.

[@ozcarplayz1656]

About the supercharger boosting. In modern airplanes it's called ground boost. In modern reciprocating engines, a turbo is used to keep the same engine power up to a certain altitude, this was done with a type of wastegate which would close as altitude increased. But during ww2 you could not really leave any performance on the table. So many planes, especially late war ones, used superchargers which could change gears and therefore spin faster and deliver more air to the engine. This was done manually on some airplanes and automatically in others. The p-47 is an odd example as it featured both a turbocharger and a supercharger. This gave the aircraft pretty good high altitude engine performance On the other hand, the germans used extensive use of MW-50 as well as GM-1 mixtures. Basically GM-1 mixture is just nitros oxide injected into the manifold of the engine(at very high altitudes) and coupeled with MW-50(50% water 50% methanol) injection could keep up with mustangs at high altitudes A little sidetrack but i hope this clears things out. I maybe missed the part where you said it's ground boost it is still morning here afterall...

[@jonathanalexander7225]

Really nice piece of work. One thing I would have personally added would be contra rotating props. This design as is would have the same vice that most heavy, fast WWII fighters had, namely, the pronounced torque twisting that plagued the P-51, Fw-190D, and other high powered fighters. Eliminating that torque is a tremendous boon to dogfighting capability, allowing the pilot to eke out even tighter and faster turns.

[@HelmutGaming]

It has some similitudes in design to the BV-155B-1 and the Ta-152 H1

[@RunninWild17]

Very cool concept. Might recommend modifying the underbelly scoop with a cooling door in the rear. That way you take advantage of the Meredith Effect to reduce drag/increase overall thrust. Also the engine cowling, while very sleak, probably does not offer enough space around the engine block for adequate heat dissipation. The Luftwaffe had this issue with the He-177, where they tried shoving two engines into a nacelle that was far to tight, and had huge problems with overheating, bursting into flames and killing the crew. Still a great concept, just needs a bit of refinement.

[@irritatorgoner1087]

dear god, i love absolutely everything about this aircraft. it's almost a combination of the mustang, the bf 109 with the wing design of the b7m2, although i've finding strange the use of a inverted v engine instead a regular one, but since this problably not a German engine (wich will burn as the sun) and i'm anyone for talk bullshit just gonna say that the design it's a true dream of aviation. i was also thinking that with the guns in the nose u can have a lot of setups in the wing such bombs, rockets and addition guns like the 109 and the 190. Let's make with a radial engine next time, or not who i am to say?

Just one thing sticks out to me: The nose reminds me of the F-4 Phantom, although the Phantom's nose is probably longer. This isn't an issue for, say, a Fox-2 fight, but if you're turning and burning trying to get a gun solution on a bandit, a long nose can obscure the target, meaning you have to take a less straightforward deflection shot.

Late war fighters needed to strengthen these areas as power increased. - alternatively, contra-rotating props would adress torque and p-factor. - high position of the horizontal stabilisers - looks like they might get interference from the fuselage or blanked out by the wings at high AoA.

[@SEMJW]

As for U.S. design the F8F Grumman Bearcat (nickname; engine with a pistol grip) was the culmination of piston engine fighter/interceptor development by 1944. Core values or Hard Factors need to be complimented with Soft Factors, such as mission adaptability, part/service commonality, reliability, ease of transitional training. It would be interesting to have a 'what if' of using a Wright R3350 radial that was developed for the Boeing B-29 and later for the Douglas Skyraider to power a Super Bearcat that would have a larger airframe not a conversion like the Reno racer named, 'Rare Bear'. It would be the ultimate Zoomiest-Boomiest plane with excellent hard/soft factors and could be put into service more quickly than a radical prototype based project. The Grumman Hellcat is a good example of that.

[@bradswim]

[@panzerwafflez7228]

Just curious, why did you choose a liquid-cooled inline engine instead of an air-cooled radial engine? You can save weight by not relying on coolant, they're more robust/protected, and they provide slightly more power over inline engines.

[@dannowak6468]

Enjoyed the video. When you said turbocharger did you mean super charger and if you mean turbocharger where did you put it and where is the duct work hidden? Problem with turbochargers was that they where bulky. The only turbocharged V12 I'm aware of was the P38 and it's turbochargers where huge.

[@Splomf]

I already see some disadvantages to the design. The long nose will make frontal visibility quite poor when landing or leading shots. Another thing that could be changed is that a 4 bladed propeller (while less efficient then a 2 or 3 bladed one) will provide more thrust with the amount of power this plane is pushing. I can't tell from the footage, but it looks like this plane (at least from a design standpoint) wouldn't have a very high rip speed, or very good energy retention. Energy retention is very important in a fighter from this era, otherwise you'll just be booom and zoomed into the ground cause you can't retain your speed while making turns or energy trapping.

[@FishbedFive]

Flyout: Ah, shit, now I gotta make fuselage wings now... SimplePlanes: First time?

[@b1laxson]

Though just viewing now (10 months after upload) you had some very good ideas that also inspire me. There are some technical points Im puzzling which may in part be how much is modelled in Flyout. Some critique points: = love the emphasis on visibility in the pre radar age = I do like the gull wing for various reasons including shorter thus stronger landing gear = There are pros/cons to a tail dragger. They can be trickier in crosswinds (TMU). A front tricycle you can always plop the nose down after the main wheels touched. The front tricycle guards the propeller from ground strikes in ways the tail dragger doesn't. = Biggest concern for me is the space for the top front 20 mm cannons as Im just not sure there is the length for their barrels. The through the engine barrel is a reference. Maybe they would work. On the Aircobra those top front were 50 cal MG in part as thats the most that they could fit. = Turbocharger/supercharger mentioned. TMU Flyout doesn't have us managing the ducting needing. The ducting is a secondary concern for me.

[@erich930]

Great video! I love all of your content, and I would love to try Flyout one day. Are torque, P-factor, and spiraling slipstream simulated in the game yet?

[@quentinking4351]

Three 20mm firing through the prop is certainly a choice. The interrupter gear is well known and reliable, but it reduces usable volume for the engine. Guess that's part of why the cockpit seems far back. Also I'd run the oil coolers and radiators on the side. P-51s in Korea had a devil of a time with ground fire putting holes in their radiator. But still, another great vid.

[@rederos8079]

Impressive power-to-weight isn't the only thing that really matters in terms of performance. A capable airfoil is one of the more important parts too. Thing with the high performing airfoils is though, that they were prone to some interesting stall conditions... I think P-51 was a good example of that. Bf-109 imho has one of the better wing designs, as slats were a really big help in maintaining the stability at high angles of attack. Looking at this plane you made, with a spitfire-like elliptical wingtips, a thin airfoil but a long wing chord, to me it seems like a very typical wingtip staller with perhaps quite dangerous spin characteristics... And the long wing chord with a thin airfoil makes it that when the wing stalls, it's quite agressive, as a lot of lift becomes none at once, since the long leading part of the wing would mask the whole wing at high aoa. A rounder, shorter and thicker wing would stall trailing part of the wing first, with most of the leading part of the wing still flying, providing a typical buffeting warning for the pilot and allowing for higher angles of attack->more pulling. This aircraft to me seems like a very good interceptor, but not much of a dogfighter... I am no expert though, so it would be interesting to see what somebody more professional thinks of this. But anyway, a nice interesting video and topic!

[@reinbeers5322]

[@TinKnight]

A few concerns (for a real-world application): Liquid cooled engines tend to be heavier & less reliable than air cooled. The inverted gull wing on the Corsair proved to be heavily limiting for low speed control, landing, & safety in the event of damage. There's a reason pilots preferred the F6F. 3 20mm cannons would've been pretty light armament. Many cannon-armed fighters had 2 or 4 cannons plus MGs. The 8 .50 cal on a P-47 had a much longer firing time plus a higher likelihood of hitting a fleeting target. "Nothing bad comes from being lighter"... tell that to all of the Zeroes that were shot down as soon as Americans learned how to fight. Even the F4F had a positive kill ratio against it, let alone the F4U, F6F, & P-38. The canopy looks to have a limited rear view arc compared to the later versions of the P-47 & P-51. The majority of fighters shot down by other fighters were pounced on from behind & had no idea they were being targeted.

[@OliverWhiteTailAlexander]

Altitude compensating turbochargers do exactly like you said, but there is a little more nuance to it. Is the turbo you're using here an automatic wastegate setup or fully manual? Many modern aircraft use automatic setups, where the oil pressure of the engine itself controls the wastegate, but older aircraft used manual setups where a separate control was present to control the amount of exhaust gas being allowed into the turbine. With this setup you would have a control for the throttle, mixture, prop, (the normal ones) and turbocharger. Manual controls allow for more fine tuning of the manifold pressures but automatic setups are simpler to use and less prone to pilot error. For the most part during the second world war, turbocharging was for bombers and heavier fighters, while supercharging was for literally everything else. Turbos required expensive materials and were considerably larger and heavier than superchargers, relegating them to aircraft where weight wasn't a priority. There were however some notable exceptions like the P38 with its twin boom design allowing for turbocharging as a second stage, and the Jug, which ditched the standard V engine and supercharger setup for a radial and turbocharger. The decision to use a turbocharger is interesting, and I'd love to know more about the specifics of the setup you've created. What does it weight? Why did you chose a turbo over a supercharger? Is it a single stage? is it intercooled? Is it automatic or manually controlled? boost pressures and service ceilings? Is all of this stuff even relevant to FlyOut? References: A.
