The elevator must be deflected upwards, not downwards 4:07 Anyway great video!

[@RealEngineering]

Yeap. That’s a stupid mistake that I overlooked, and even told the animator to animate the mistake.

The narrator at 5:41 says "vortice". Would he correctly mean "vortex" (plural, "vortices")?

[@jacobr7729]

While you're at it i'll point out hydraulics is spelled hydraulics and not hydrolics

[@lukeardagh3372]

The wing armament was actually seen as a disadvantage because each gun needed to be configured to converge at a particular distance, which reduced overall accuracy. The BF109's nose guns concentrated firepower and improved roll rate by centralising mass.

[@MrNicoJac]

True! However, the convergence point meant you _had_ to be a _specific_ distance from the target for maximum accuracy. But this _also_ meant that you could _opt_ for a more spray-and-pray approach at different distances. So, like, you can put all your eggs in one basket, or decide that a few rounds on target was better than none. Which was a "luxury"(?) that the Bf-109 did not have. Right? 🤔😅

[@KORInashi]

When compared one to one the wing armament could be considered a disadvantage and less pilot friendly. However when fielding planes and maintenance it could be a great advantage to have fewer moving parts and a greater number of guns firing.

[@alganhar1]

Really depends on what each gives up. Its much harder fitting a heavy nose armament on a single engine prop fighter because the prop and the engine are in the way. So while the armament is arguable more accurate, you have far less throw weight. Mount those guns in the wings however and you can fit more of them, arguably less accurate, but more throw weight, especially with the B and C wings which were the cannon armed wings. Accuracy is only part of the equation, throw weight is just as important, how many rounds can you throw at the target in the very limited period of time you have it in your sights. Given the ranges those pilots were firing at, typically less than 400 metres, often *much* less, then the argument about gun convergence become less critical, and that increased throw weight that Spitfires armed with the later wings were able to deliver to their target becomes more important. After all, that convergence is only growing less and less severe as the range closes. In other words, their are costs and benefits to both wing mounted and nose mounted armaments in prop fighters, and it really depends on what the priorities are for the air forces involved. It is no accident that the prop aircraft that mounted the heaviest nose armament were ALL twin engine designs....

[@nickmgls6523]

I once saw a video which said that the nose gun caused reliability issues

[@starstreakalex7372]

in that case both armament configurations can be seen as equally advantageous and disadvantageous, as wingmounted is preferable for flight performance but nosemounted is preferable for combat performance

[@sethb3090]

I was born in 47, and as a small child my parents were still in the habit saving any bits of aluminium foil they came across. It seems that during the war years there was country- wide effort to secure as much aluminium scrap as possible with which to build Spitfires. This is easily one of the best and thorough Spitfire documentaries I've yet seen...

Mounting the guns centerline is beneficial when it comes to aiming and gun convergence. Wing mounted guns are typically set at angle so their shots converge at a certain range, making that range the optimal range. But that also means that outside the optimum aiming is harder and half your shots will always miss. Great video! The Spitfire is just beautiful!

[@Stealth86651]

While true, it's not as much of an impact as you think. You generally didn't take shots until you were *very* close, so you didn't exactly have much of an effective firing distance to allow the convergence to break up the shots much. This effect is much more prominent in video games than it ever was in real life. You really only had an effective range of 250m, and around 400m for bombers under best conditions, otherwise you're just wasting ammunition.

[@Kman31ca]

@@Stealth86651 Oh it had an impact for sure. The Bf-109 spent a lot of time also shooting at bombers, which with a centerline armament meant they could shoot accurately while keeping out of the bombers defensive guns.

[@Stealth86651]

He was a young man in his 20s when he also had that great responsibility in signing off those planes, after being serviced, AS 'fit to fly'. Years later - in middle age - he admitted he would never have the nerve to do that type of job again. But youth is a wonderful thing, and he - and many more like him - did their jobs, and did them well. He was one of the lucky ones to survive the war, live to raise a family, and lead a good life. RIP Dad, and to all the other young men and women who fought during WWII - and the many who did give their lives - may you rest in peace, also, and know that you ALL were from the 'Greatest Generation'. :)

As someone who has studied the Spitfire all my adult life and also flown one, can I say that this documentary is of impeccable quality. There are a few misplaced clips of Hurricanes and Hispano Buchons, but that's forgivable. Your explanations of aerodynamic principles are very clear and accurate, and you rightly focus on the key points that made the Spitfire an apex predator: Bev Shenstone's wing design; the power to weight achieved by Rolls Royce engines; and the radiator technology that Supermarine had developed during the Schneider Trophy campaign. I'm really impressed and Nebula has instantly become a trusted brand. I have taken out a sub and look forward to much more.

Actually in a turn, you increase the deflection of the elevator, not decrease it as stated in the video; that is the rear edge of the elevator move upward. This works to move the tail downward and the nose upward, which increases the angle of attack, and thus increases lift to compensate for the loss of the vertical lift component while banking.

[@cadenorris4009]

Another thing to note is that an aircrafts turn performance is not solely dependent on it's turn radius, although it is important for many maneuvers of a dogfight (one circle, scissors, etc.). The other crucial component is turn rate, or how many degrees per second the aircraft can complete in a turn. This is important for two circle dogfights, as well as other fights. If you want to learn more, look up one circle vs two circle dogfights!

[@MrMarinus18]

The Bf-109 did have 2 advantages. The first was a higher rate of climb due to lower wing loading. The second was the high pressure fuel injection engine which meant it could perform high speed dives. The merlin engine was fed by a carburetor which meant it would stall if put under the same forces. The main reason the Germans were unable to achieve air superiority though was the home field advantage. British fighters could afford to fight far more aggressively than their German counterparts as they had full fuel tanks and could use them up as they would just land. The Germans had to consider the distance back home as well. Also quite a few planes that are shot down don't crash. Holes in the fuel tanks or a compromise of the engine or limited damage to the flight controls can render a plane unable to fly but still capable of landing safely. If a British plane got disable by light damage the pilot would just be put in a different plane and the plane would be repaired. If the same thing happened to a German both the pilot and plane were lost. When the roles reversed the British didn't fare much better than the Germans had with their bombings. What made the bombings successful was the collapse of Germany's air defenses due to the overstretching of the eastern front and the incompetence of Gouring. Germany never developed a well functioning fully integrated air defense network like Britain did and by 1943 even if the British lost a lot of planes that didn't matter due to the practically infinite resources provided by the US.

[@MDzmitry]

@@MrMarinus18 First of all, in wing loading a Spitfire would always outperform a contemporary Bf.109 model. Secondly, 109's advantage in climb rates (albeit not tremendous and at times non-existent) was provided by the sheer horse power per kilogram ratio. And the never-ending stanza about fuel injection falls apart since 1942 and the implementation of Merlin 66 (alongside US-produced 266 model), 70-series and every later iteration. Even if you consider 1942 "late", fuel injection alone doesn't win battles, it only gives a chance to escape alive. Didn't stop Mk.I and (later on) Mk.V Spits from warding the Germans off above Britain, Malta and North Africa until Mk.IXs arrived.

[@jlglover4592]

Thanks for your work, in general, but specifically on airplanes. Your videos on the P-47 Thunderbolt and the A-10 Warthog were amazing. This video on the Spitfire is awesome, too. The Spit was the most beautiful fighter of WW2, imho. The P-51 Mustang would be a great analysis for you. The way it was mediocre until is got the Rolls-Royce Merlin engine would be interesting. Thanks for your efforts, from a guy who lacks the math skills but can understand your explanation.

[@masonborden5594]

Ive always felt like people dont appreciate the absolute workhorse that its the p-47. It was a vital plane introduced at a vital time, and while it had its issues, much like the m4 sherman, it was the right weapon at the right time. Not the best, but far from the worst.

[@sheldonholy5047]

The P51 was much more aerodynamically advanced than the Spitfire, especially in cooling drag reduction. However the Americans struggled with supercharger design, and it was the introduction of the Merlin 66 that greatly improved high altitude performance. This is what made the difference.

[@slammerf16]

@@sheldonholy5047 P51 was a great plane, although it couldn't climb or turn like a Spitfire. Its strengths were in other areas - especially range. Also, and this is not meant disparagingly, the P51 was cheap to build which gave it a big advantage over the P47 and the Spitfire in wartime. US mass production made a huge difference to the outcome of WW2 and the careful use of strategic materials was a big part of that.

[@sheldonholy5047]

@@slammerf16 also a very good point - the spitfire did take around 30-40% more man hours to manufacture than most of its contemporaries, namely the Bf109. This is quite often overlooked. The Germans did well considering their lack of many materials which the allies had access to, which forced them to use ball bearings instead of sleeve bearings, which is quite undesirable in large engines.

[@PiersLawsonBrown1972]

Very good presentation, one minor flaw that has already been covered a lot. The saddest part of the whole Spitfire story is the death of RJ Mitchell before he got to see what his plane was truly capable of, perhaps a brief mention of that would be nice.

Great video and great visuals as always! Please note that at 4:11 the elevator should be deflected upward to make the airplane pitch up, increase the angle of attack and, ultimately, produce more lift (and more drag).

[@garrycollins3415]

Yes. Elevators up gives downward lift causing the aircraft to pivot around the center of mass which pitches the nose upward increasing lift.

[@user-do5zk6jh1k]

The wing is also where all the appreciable lift comes from. The elevator just produces a rotational moment to increase the wing's angle of attack. I'm surprised Real Engineering made this mistake. He's usually a lot better at getting his facts straight, even on the topic of aviation.

[@mrjockt]

The layout of the guns in the Bf-109 did have its advantages, since all the guns, especially in the later models from the 'F' onwards, were located in a small frontal area, two above the nose and one through the propellor spinner, the fire was concentrated and meant a shorter burst did more damage.

[@ancientheart2532]

This is the best I've seen. In particular, you talk about the advantage the inverted, fuel injected Daimler-Benz Bf109 engine had in neg. G manuvers, compared to float carb. Allied aircraft (Spits...Mustangs). To wit, 109 pilots could push straight over in a dive; Allied aircraft....as you pointed out, had to roll over inverted or the engine would flood.

[@HarryJones-xr5td]

Well worth the time. Lots of relevant facts.

[@icojb25]

An elliptical taper to the planform does not require that the leading and trailing edges both taper equally - rather it requires the length of the total chord in the spanwise direction to taper elliptically. How the designer chooses to arrange (stack) the airfoils (fwd and aft) in the spanwise direction is totally up to them, and, as was done in the Spitfire, the airfoils are often stacked so the 1/4 chord is straight - yacht designers do this very often too for rudders, to the turning moment is colinear to the rudder shaft. Remember the local amount of lift of proportional to the length of the chord, so (assuming you have no washout and the same airfoil section), all you need to do is taper the total chord length along the span in an elliptical fashion.

[@ericalawson631]

Another clever innovation in the radiator design was that cool air drawn into the radiator was heated by the radiator core causing it to expand, then when it left the radiator, it was travelling significantly faster than when it entered, thereby creating a small amount of thrust (in effect a jet) which also partially negated the drag created by the radiator. Clever man Mr. Mitchell. we can only imagine what kind of designs he would have come up with if he'd had access to turbojets.

[@mikeland3453]

Thats like saying the pilots ate beans before every flight because farting added extra thrust.....

[@ericalawson631]

@@mikeland3453 lol, true though very clever design of the radiator inlet and outlet

[@bobsakamanos4469]

Actually, that radiator cooling scheme you describe was due to Meredith (1935) at RAE. The Spitfire radiators were a bandaid solution when the glycol liquid / radiators were adopted. That space in the wings was originially intended for fuel tanks. Meredith and RJ Mitchell collaborated on an upgraded version of the Spitfire (Type 312) with a more efficient ventral radiator which RJ was working on when he died in 1937. The square, wing-mounted radiators were a main source of drag and didn't really enable the Meredith effect unfortunately.

[@SuburbanDon]

I was sure how interesting this would be but I really learned a lot. Good job.

[@masboyrc]

Thank you for explaining and presentation, appreciate it 👍

[@philipplenzlinger445]

Great content, as always! However, I’m not sure your explanation of a narrow radius turn is correct: in a steep turn a pilot will pull on the stick to add some nose up attitude which adds a vector complementing aerodynamic lift of the wing to increase vertical lift and a centripetal force thus diminishing the turn radius an keeping the aircraft in horizontal flight. A pull on the stick will deflect the horizontal stabilizer upward, creating a downward force on the tail (nose up of airplane) In the video the contrary is shown and told. Second small correction: the pressure equalization on the wingtip will produce a VORTEX (plural vortices) around the wing contributing to induced drag. Keep up the good work. I always enjoy your videos. Thanks!

[@dr.kraemer]

we get ourselves into this kind of trouble when we decide to use pluralization rules from other languages. 'vortexes' sounds like a perfectly cromulent English word to me.

[@bobsakamanos4469]

yes, the video made an error regarding the elevator direction, but was bang on regarding the induced drag due to increased AoA. The Spitfire elliptical wing generated less induced drag than other fighters, especially at higher altitudes, despite having a thin wing. Brilliant design.

[@johnharen9921]

I think you should read "Secrets of the Spitfire" - the biography of Beverley Shenstone - the senior aerodynamicist working for Mitchell . The elliptical wing was not merely chosen to cover the guns. Apart from the reduction in induced drag, the wing , which was actually 2 semi ellipses with a common major axis on the 25% chord line, had many other benefits apart from providing enough depth to cover the guns and undercarriage.

[@DevinGibson6316]

ꜱᴇɴᴅ ᴀ ᴍᴇꜱꜱᴀɢᴇ👆👆..

[@bobsakamanos4469]

The benefits of the elliptical wing were first described by english aerodynamicist, Fredrick Lanchester in 1907. Prantl expanded on his work in 1918 with the Lanchester-Prandtl wing theory. Operationally, its gentle pre-stall buffet allowed the Spitfire pilot to ride the edge of the stall in combat without fear of sudden wing stall/ snap roll. Hurricane pilots didn't have the same warning and hence were more reluctant to push their aircraft to the limit. Kittyhawk pilots also were afraid of the aileron snatch and flick roll if too agressive in the turn. The P-40s also had a tendency for the rudder to lock up in certain manouvers. Spitfires saved many a pilot due to its fine handling.

[@ianoverseas]

[@punkypink83]

Love this. Recently went to the RAF museum and saw quite a few Spitfires! Would love a video on the Hurricane too. While the Spitfire is iconic, I think of the Hurricane as the unsung hero of the Battle of Britain, especially as it accounted for 60% of all enemy losses

[@nathanz7205]

60% of air to air kills maybe

[@the_ejj]

that may be true, but the spitfire was a anti fighter fighter where as the hurricane was anti bomber. without the spitfires luring and engaging the 109's the hurricane's would not have such a high kill rate

[@joeblack8915]

People who use that argument fail to mention that during the battle of Britain, the Spitfire only had 19 squadrons compared to the Hurricane's 30, yet the spitfire shot down a greater percentage of aircraft in relation to its smaller numbers. Had there been parity in the numbers of the two aircraft, the Spitfire would have easily outstripped the Hurricane's figures on a one-to-one basis. Leaving that aside, these two fighters, along with the many other aircraft involved in WWII, helped turn the tide of the war.
