I’m an Aerospace Engineering major and in my intro to AE class we had to make gliders. And my friends team made one with a circle wing to mess with the tryhard kid in their group. It was surprisingly successful.

[@tomaskolacia8834]

On the Kuyusu those wheels on the stabilizers are there so the stabilizers don't rub off during take off. The rear wheels are from under the wings, and the "struty things" are the front and the back wheels.

[@ThePlumAbides]

Yeah, I'm kinda hoping he revisits this video and does the Kuyusu right.

[@kittensandmarmalade]

He also didnt even try disabling the bottom tail fin's controll surfaces, which they wouldnt have had.

[@MikeDCWeld]

​@It's Sessy a bit more attention to detail and looking at the picture for more than 3 seconds would help a great deal.

[@chrissugg968]

I think the 'strutty thing' is the aerial, not the wheels.

[@mfg-music5875]

also the plane was facing downwards so he would never take off doesnt matter the speed, thats why the real one faced upwards so i generates lift and not act like a f1 car...

[@bt1234567892010]

I'm genuinely surprised the least flying-capable looking plane actually worked, the ring-wing is neat.

[@jamoecw]

it is used in different designs and modern normal wings use some stuff on the wing tips based on the closed wing design to minimize wingtip vortices that creates drag (those white lines). a variation of the ring wing is a box wing, and you might have seen those before since it is simpler to make and design.

[@bt1234567892010]

@@jamoecw I think i've seen the box wings? Still that's interesting to know~

[@bt1234567892010]

@Lux Aeterna there's also crosswinds that could be an issue. I imagine a strong crosswind would make it very unstable.

[@udu5450]

yah it has better glide then normal planes i don't know if that's a fact but a ring paper airplane flys much farther than the normal ones so you know making that bigger should have the same effect but who knows

[@jetsonian]

When you're making replicas of vintage craft, you should disable engine vectoring and rely on the control surfaces to generate lift. Thrust vectoring wasn't available in jets until the 1990s.

[@freewilly1193]

​​@mandellorian while perhaps potentially accurate of some, it is still an important note, as many of these designs may or may not have had them. They were prototypes. However, this doesn't necessarily mean that they all had access to the top engineering.

[@Roller-Coaster_Creations]

7:18 The thing why the biplane didn’t took of. Was that the control surfaces were not rightly balanced.

[@ryanhamstra49]

Also the jet is too high for the length and is causing it to pitch forward. Needs the control surfaces further back

[@bryaneveridge2104]

He managed to not bother with correctly setting up the control surfaces on any of the ones he built. 😂

[@martijnkosters9024]

5 tonnes of fuel certainly didnt help matters.

[@Aston3003]

And the main wings are not angled too

[@jonhg92]

Ey. Dont butcher the guy. 😂 hes a civil engineer, not an aeronautical engineer

[@jimmymcgoochie5363]

The ring wing would probably fly a lot better if the top part of the wing was further back (more sweep), giving the control surfaces more leverage. For the designs that didn’t work out, you could say they… didn’t take off (sorry)

[@sgador]

I mean the pic clearly had landing gears in a trike formation the wheels on the ends of the vertical stabs was just there incase of a bad bounce edit: This is for the Shinden

[@RetirededKat]

When I was in 6th grade I made a glider that was simply a ring with a folded leading edge. It was a great glider. The extra weight and thickness on the leading edge kept it straight and created a pressure differential similar to an aircraft wing.

[@derekv4552]

Once again, in love with the design. The architect is growing in this one

[@AsteroidWrangler]

You may be a civil engineer, but when it comes to my field, you're definitely an architect. Still, you gave it a good bash.

[@budshoot6951]

Challenge - make the RingWing efficient! It showed so much promise - just needs some tweaking and it seems scaling up the wings would greatly help. Awesome video though!

[@jacksonnovak6568]

Fun fact swept wings are really only useful close and above the speed of sound

[@death99ification]

for the leduc. the cockpit was actually INSIDE the air intake. you can see the cockpit located in the air inlet in the photos.

[@rpgaholic8202]

Things to note, your Kyuushu failed because the IRL plane was pitched backward to help with take-off, yours was pitched forward which is why you crashed before getting airborne.

[@BGerbs66]

Also the "struts" he put on weren't actually on the plane. The picture obviously shows a front retractible gear with 2 more gears in the rear

[@MikeDCWeld]

​@BGerbs66 yeah, who knows where he got the struts from. Also, how did he not see the very obvious landing gear?

[@tonypepperony3727]

you should try to make the Tail-sitter. it takes off and lands on its tail (vertically) then tilts horizontally for forward fligh

[@angry_ike7628]

Matt was looking at the paintings, like at 1:59, for the "strutty-thing," not the photograph. And I'm pretty sure that strutty-thing was an instrument antenna wire like for radio or something. Nearly all aircraft of that period had them. Just google "WWII aircraft antenna" and check the images to get a better understanding.

[@HaoPham-ls2cs]

Cxe?

[@wolfwrcx]

a small tip about designing flyable planes in KSP: center of mass should be slightly in front of center of lift. too far forward and can't nose up. behind center of lift will make it naturally nose up. Wheel location depends on pitch controlling surfaces. If you use Elevator, which pushes tail down, making it squat, then placing wheels at the center of mass makes sense, but if you have Canards, then it doesn't, because they just lift the nose up.

[@iuhihs]

4:41 you are missing 2 larger wheels under each wings.

[@viralvirtualofficial]

omg the Belphegor picture was taken actually at my hometown! sadly its no longer there, it was removed, but im very surprised im seeing that exact pic in this channel, that plane was part of my childhood, everytime i was watching that plane when we went by it, since then i love flying and actually was flying gliders at the exact same airport, where this pic was taken!

[@creeperspartain3935]

I don't think Matt knows much about how control surfaces work. Matt, please look up the difference between ailerons and elevator control surfaces. Your ailerons shouldn't both go up when you want to pull up.

[@bmthfan1231]

You're right, he's your friend and will totally notice you

[@thesovietvorona1007]

The first one was actually made after the American XP-55 Ascender which is fairly similar in looks. So that should be a definite mention. Only three ever built. Two are gone and we have one left in a museum in my state. But yeah. That’s the OG.

[@cybercat7851]

I’m not sure if you noticed, but on the 3rd plane, the cockpit is in the engine. You can see it in the ramjet cone, not mounted on top.

[@freewilly1193]

Thought that was what I was looking at...

[@andrewince8824]

It was also plexiglass. No hope of ejection, no rearward visibility and the pilot needed to wear brown trousers to fly it. Awful idea.

[@jenniferstewarts4851]

Kuyusu had "5" landing gear. the main nose landing gear with its door (what you called a strut), the wing mounted landing gear, which made up the main gear, then 2 small wheels on the tails to act as strike gear, these were not supposed to touch the ground or even be used, but instead act as "strike plates" if the plane over rotated on takeoff. As to planes not looking like that.. they actually do... a lot of modern fighters now use the same "style" such as the eurofighter.

[@evanhurt8673]

I haven't watched you in months and I just saw this video and I remembered I loved you

[@RealCivilEngineerGaming]

Love you too

[@davidneugebauer8021]

Im sorry but you missed the point to the first plane. It has to look upwards, in your video it was pointing downwards, it was pushed into the ground and crashed :)

[@Makujah_]

12:08 I'm not a kerbal player nor an airplane engineer, but isn't the wing's orientation on the Ring gone wrong after the first flap? What I mean is, I think some of the wing bits create negative lift because of the upside down shape. Am I wrong?

[@oliviervm86]

not to nitpick, but u missed wheels on the first plane. there are more weels under the back wings

[@Friendly_Neighborhood_Dozer]

0:18 the beluga looks (and probably is) like someone saw a normal cargo plane and went “MORE!”, and someone else just chopped off the top of an airbus and slapped a giant pipe the size of a railway tunnel on top.

[@Streaky100001]

Ah, Matt, that strut on the J7W.... it's not actually a strut at all. It's a piece of wire anchored at the 2 masts. It acts as the antenna for the HF (long range) radio.

[@woobilicious.]

Matt's inability to design a flying plane is probably the biggest hurdle in all of these designs, center of lift, and center of weight are so important, The Kyushu design can't take off because the wheels are too far back and it has to leaver the entire craft upwards to angle the wings upward, you want the back-wheels to be closer to the center of weight so it pivots around the wheels (which the original design has), and also designing the plane so it's nose is pointing upwards, not downwards, helps too, and that would be easily solved with shorter back legs.

[@meneertjeman2719]

Maybe you could try in the next vid the Dutch V Wing plane, where the passengers sit in the wings. I enjoy your vids.

[@andrewince8824]

Not heard of a Dutch airframe like that but the Junkers G38 used a thick wing with passenger cabins at the wing root. I wouldn't be shocked if Anthony Fokker or maybe Koolhoven gave such a design a fair go. Exquisite aeronautical engineers among that lot.

[@philtheninja7208]

the first one, those small wheel were just stabilizer wheel, its got the standard trike landing gear config

[@No1sonuk]

4:34 indicates the problem with the Kyushu. You have the elevators on the main wings, so it's just pushing the back down. It should use the canards (front stubby wings) as the elevators. That would pull the front up. As for "...planes don't look like this..." Look up "Eurofighter Typhoon". 7:30 Your main wings have elevators again. You're not creating rotation around the CofG. It should be just ailerons on the wings, with the elevator on the tail. 9:27 Leduc - Again, elevators in the wrong place...

[@AddSomethingCreativeHere]

Matt. I challenge you to make a realistic Bomber like the tu 95 in Simpleplanes

[@kimi1984]

So "Leduc" was the inspiration for Thunderbird 1 which beggers me the question... Do you think you could make the Thunderbird vehicles in Kerbal?? 🤔 Great video by the way!

[@antonycooper2419]

the 1st one you missed the wheels. 1 front then 2 rear. the 2 on the flaps was prob to stop it from scraping the ground on take off :)

[@rickbrown8206]

Matt, may be time to try a new plane design that's right up your alley. Have you seen NASA's new X-66A they just unvailed? It has trusses and struts to help with transonic flight. Thought you might be interested!

[@GK34779]

There are actually ring-winged plane ideas so well done!

[@vampyr2936]

The struts and wire underneath the plane are the antenna for the long range radio, it's one of the only near universal features of WW2 era aircraft

[@lovebus00]

You can make propellers by angling wings. They actually work pretty well

[@Atlessa]

But how do you turn them? Last I checked there's no moving parts (ie motor hub) in KSP2 yet.

[@jaym8299]

On the lunac the outer wheels weren't actually cantered out, just appears that way in the photo. They just go straight back but yeah cool stuff my dude.

[@jfolz]

Is there any chance RCE will ever learn how control surfaces work?

[@zyeborm]

I dunno man he still tries to turn planes using rudder only. I used to think the phrase "mechanical engineers build weapons, civil engineers build targets" was just a pithy quip but even looking at polybridge he still hasn't discovered the 4 bar linkage even on maps that basically come with one built in lol. Anything that moves is his enemy.

[@AddSomethingCreativeHere]

No.

[@bmthfan1231]

​@@zyeborm you aren't smart

[@willie9899]

Your ring probably didn't want to pull up because it's CoL (center of lift) was too far behind your CoM (center of mass). If you pushed the ring forward (and possibly the engines backward), it should be a little more maneuverable. With the CoL being so high, however, it's going to desire a flatter pitch regardless

[@ShinQdan]

3:03 it's not for strength, this single "strut" is not a structural part of a plane, it's an antena.

[@Thoran666]

I hope you improve on the ring wing design in the future RCE. That's quite a unique design and I feel feel a few extra wings or flaps it could perform a lot better. For the UKSE!

[@cyberfutur5000]

I really, really, really want to sit over a pint with you ant tell you how air planes work. Seeing a Brit saying that the french where on to some thing hurts my soul. If you ever are in Germany ring me up! You can tell me how to bridge stuff and I explain how to fly over unbridged stuff:D (Actually I really adore french air plane design)

[@i-own-cartel]

How does your pc not explode at 60+ fps?! What godlike specs does your pc have? Anyways I love your ksp videos and I would love to see them being made more frequently. Maybe you could design your own rockets again instead of recreating other rockets. With those rockets you could fly to other planets and just mess around in space..

[@davewebster5120]

I wish you'd given the shinden better landing gear to at least see how it flew. But really cool video!

[@jakec7532]

I feel like you missed out on the whole concept of lift that planes are centered around as the wings need to be angled

[@C0R3894]

You can recreate the prop engines with the smallest jet engine and reverse thrust it when it’s in front and normal on back

[@zachtribbett9731]

This should be a series!

[@hixonreaper3546]

Hey Civ, the Japanese pusher prop didnt have support struts underneath. That was the front landing gear and the back landing gear which had air surface covers for when the gear was retracted.

[@Awesomekraken677]

They didn't make the ring wing cause while having the fuselage in the wing made it more fuel efficient, that was cancelled out by the massive increase in drag.

[@misek_limbu]

7:32 I thought this was gonna be a cannon event

[@jason59k55]

FYI your parts are not snapping correctly because you need to make sure the little magnet icon on the bottom is glowing yellow, that turns on the snap

[@cameroncashatt692]

i cant imagine how hard it would be to produce main spars strong enough to support that wing surface on the ground. then support the plane once in the air. That's probably one of the main reason.

[@criggie]

The Leduc locates the pilot's seat inside the nosecone of the engine. THAT's why it was so weird. Bailing out is likely to result in pilot-injestion into engine.

[@marcalcantara1174]

I love your silliness but "realistic" stuff like this is what got me subbed a lot ago, back when you recreated IRL bridges on poly bridge, please make more videos like this 🙏 (it's okay if you don't)

[@oasntet]

The ring wing would have had better control if you'd left the flaps alone; the flaps at the top of the ring were behind the center of mass, so if you want to pull up you want those to push the tail down.

[@velarswood]

Hoooold on. He had a proper architect moment. Isn't the jet at the end just a fancy biplane and he clearly says jet biplanes don't exist for a reason...

[@replay_pete]

About PZL M-15 here is a fun fact. "...In reference to both its strange looks and relatively loud jet engine, the aircraft was nicknamed Belphegor, after the noisy demon..." Source: Wikipedia.

[@meatharbor]

The Shinden's neat and all... But I'd like to see something like the Horten Ho 229 or Vought V-173, both serious aircraft that serious people took seriously.

[@sweetbutpsycho7358]

You could do an 8 style wing ether side to side or top to bottom and it might give you more stability

[@TheLazerKiwi]

did you know that the cockpit of the leduc was at the ''Ram'' Part of the ramjet and not ontop?

[@jfperkins5076]

If there's a tail, please turn off pitch on the main wing control surfaces. It'll help.

[@TheAquabears]

3:21 - I think that the thing you think is a strut is actually a radio antenna.

[@denizalicesme9797]

We need more KSP 2 videos for the honor of the UK Space Agency!!!

[@Notaracialslur]

7:11 your elevator are on your main wing so the force of the horizontal stabilizer is being canceled out by the wings having the elevator control so essentially the back wants to go down to pull up but the front won’t let it

[@flimph]

From the image on the video i wondered if this based on a very efficient design

[@VENOMFPV1995]

The biplane was failing to fly due to the ailerons being used as elevators... think of it as downforce... if your main wing ailerons are angled upwards it's trying to push the aircraft down instead of creating lift.

[@Lindrios]

"Now let's see why Jet-Powered Bi-Planes don't exist anymost." I wasn't expecting to find that statement to be so emotionally moving and adrenaline inducing 😅

[@Astraeus..]

For the ring-wing design to be able to turn you'd probably need to make the vertical sections out of a tail-wing/rudder. That way they can direct airflow appropriately and allow turning normally (by which I mean without having to make a banked turn).

[@Atlessa]

KSP2 doesn't differentiate between rudder and wings, so the only change he cpuld make is in the dimensions of each segment.

[@brickbrack_]

7:30 "There's a building coming towards me" I don't think that's quite how that works... 😂

[@alexanderamborsky8245]

I don't remember what they're called, but I think most airplanes have those small tail wings for better stability. Do they not work in kerbal or has RCE just forgotten about them?

[@AddSomethingCreativeHere]

The horizontal stabilisers?

[@shawnbolack5703]

I love this video concept, it will also be fun to see it in trail makers or something like

[@andrewince8824]

They definitely weren't. It used a ramjet, in fact, it was a giant ramjet with pilot sat in the intake. A plexiglass cone with no rear visibility and 0 hope of ejection because he was sat in part of the intake. Terrible design. The design shown in this video almost has more in common with a MIG 15/17/19/21 than the Leduc. Probably why it flew so well and Bill didn't get ingested by the engines.

[@jamoecw]

for experimental aircraft KSP1 works better, though you can't adjust wing shape so you need to be a bit creative when making them.

[@chrissugg968]

You can just turn the wheel units backwards, if you need a wheel to be closer to the nose.

[@acompletelynormalhuman6392]

8:08 this is because it is designed for slower flight then most mondern aircraft. when the aircraft gets close to the speed of sound it's wings will experience supersonic flow even before it breaks the sound barrier the supersonic flow over the wings makes it incredibly difficult to control (if possible) so modern wings sweep backwards to delay supersonic flow over the wings. I don't understand fully why this works something about the spanwise and cordwise flow also 10:45 the idea of culculer wings in general is to get rid of wing tip vortesy wich cause drag. they do this by eliminateing the wing tips. this is also why toradel propellers are a thing they don't have a tip at the end so no wing tip vortesy from. I'm assuming the reason why this plain was abandoned was the same reason a similar fighter jet desing the Coléoptère was abandoned. It was abonden for numoris reasons but the big one was the wing proved to be incredibly unstable and one of the prototypes even crashed. for camushal jets the wings usually aburtyly curve up wich reduces wing tip vortesy as the high pressure and the low pressure zones combine less. I don't know why modern fighter jets don't do this but I'm assuming it's because their wings are shorter so it may not be as much of a problem I also think it might affect the radar cross section

[@gaybowser3609]

The J7W1 was actually supposed to have its propeler replaced with jet engine but due to Japan loosing WW2 it never happened. So your depiction of the plane is somewhat historically accurate.

[@ItsSlusher]

tThe ring-wing is so cool! It would take up less space at an airport because of the reduced wingspan wile filling the same amount of passengers, Sooo... Smaller plane with the same capacity of big plan = More terminals = More flights without the cost of expanding the whole airport. It must be an older design from some time ago since it says its by Lockheed and not Lockheed Martin

[@Khaztaroth]

I played the video and heard "Hello fellow engineers!" then I realized there was no audio coming from my computer, my brain just perfectly remembers the intro and will play it on it's own.

[@nidodson]

Given how no one is playing KSP2 on Twitch anymore already, I think we can declare it a failed EA Launch, exactly how the nay sayers said. Also, given what the reviews of the recent updates have been, it makes clear the game is still in alpha. (Did they think the A in EA meant Early Alpha, instead of Early Access?)

[@3DPDK]

You'll find that high speed aircraft didn't start using swept wing designs until the US began experimenting with hypersonic speeds and rocket propelled aircraft in the late 1950s and early 1960s. The X-1 and X-15 even had a tapered but straight wing design. It wasn't until attempting to solve the issue of oscillating wing tips just at sonic speeds that they discovered that the delta (actually conical) shape of the air wake could be better utilized by sweeping the wing to match the shape of the wake. Only the F-86 used in the mid 50s by the US Army Air Force had a modified swept wing hinting that aerodynamic engineers were beginning to understand sonic air perturbance. The most stable paper airplane you can make is a strip of paper stapled into a ring with a paper clip used for ballast. As an actual aircraft it MUST use a rudder for turning as there is no angled horizontal orientation to the ring as it rotates around it's center axis.
