Tandem Wing Aircraft Were Almost A Thing In WWII | Miles M.35/39 Libellula [Aircraft Overview #83]

[@RexsHangar]

Please forgive my average animation skills, I am still learning :) F.A.Q Section Q: Do you take aircraft requests? A: I have a list of aircraft I plan to cover, but feel free to add to it with suggestions:) Q: Why do you use imperial measurements for some videos, and metric for others? A: I do this based on country of manufacture. Imperial measurements for Britain and the U.S, metric for the rest of the world, but I include text in my videos that convert it for both. Q: Will you include video footage in your videos, or just photos? A: Video footage is very expensive to licence, if I can find footage in the public domain I will try to use it, but a lot of it is hoarded by licencing studies (British Pathe, Periscope films etc). In the future I may be able to afford clips :) Q: Why do you sometimes feature images/screenshots from flight simulators? A: Sometimes there are not a lot of photos available for certain aircraft, so I substitute this with digital images that are as accurate as possible.

[@rulingmoss5599]

What about the old speed record racing planes of the 1920s and early 30s? Love what you do!

[@hungryhedgehog4201]

The hangar looks fine if you are using blender, I'd recommend using Cycles to render so it gets raytraced with shadows and all and looking into how to set up the camera like a real one, that's something people often forget, can make things look a lot more "realistic" like it was actually filmed.

[@SoloRenegade]

this airplane doesn't have 4 wings. if a Tandem Wing = it has 2 wings if a Forward Canard = it has 1 wing

[@Smothtiger]

Burt Rutans design of the Quickie is among the more modern tandem winged planes that I know of. Fun to learn of even earlier design prototypes.

[@ErikssonTord_2]

And the tractor propeller solved a lot of issues, but the landing gear was a probelm which Cozy avoided!

[@RichardBetel]

I think the quickie was a later design of his, too. But now I wonder about his influences in the design of many of his early planes. The Vari-EZE (his second plans-built) really looks a lot like the miles planes, not to mention the Ascender.

[@allangibson8494]

The Westland Lysander Delanne tandem wing variant deserves a mention too.

[@ErikssonTord_2]

@@RichardBetel His first was the Vari-Ezy, inspired by the SAAB Viggen fighter. For a long while Rutan argued that canards were best, and now he thinks otherwise. The noisiest aircraft around is the Italian looker Piaggio Avanti, the beyond doubt noisiest propeller aircraft in use. And that is natural with some air accelerated by the powerful propellers to over the speed of sound, like when you bang with a hammer on an anvil. You want to have propellers out of the turbulence, like on the later designs of Miles, and you want a conventional tail for manouvering, but a canard that takes care of trim-changes is excellent, and that is how the Avanti is designed, and the SAAB Viggen only missed the conventional tail!

[@EatPezzzz]

@@ErikssonTord_2 Rutan's first design was the Vari Viggen, not the VariEze.

[@MediumRareOpinions]

Neat, I've never even heard of these prototypes and that's exactly the sort of thing I appreciate about yours and similar channels. Bringing attention to something obscure and interesting.

[@gingernutpreacher]

I heard of the second one but never in this much detail

[@pricelessppp]

And ideas for the war thunder team!

[@JohnSmith-bx8zb]

The Miles company designed and started the build of a jet powered aircraft that would take off, break the sound barrier and land on its own retractable undercarriage. Under lend-lease the drawings and information were sent across the Atlantic. A similar looking aircraft the Bell X1 appeared but with a rocket motor that went on to break the sound barrier. Meanwhile back in the uk the Miles aircraft was cancelled but a scale model was taken up by a Mosquito dropped, it flew, broke the sound barrier and flew off into the vastness of the Atlantic.

[@sablatnic8030]

Around 1980 I happened to have a chat with a gentleman, who was building an RC-model of the M.39, and had phoned George Miles about details, including C.G. The C.G. had Miles said, and after a lengthy pause, the C.G, no, I have no idea where the C.G. was, or where it should have been. But he was very helpful with other details.

[@blaze1148]

It was not 'a weird aircraft of the War' - it was just built 'during' WWII.

[@jjmcrosbie]

Thank you for this video. And how about making one for the Miles Messenger? Produced to meet an Army requirement for an air observation post. Then the MAP threw all their toys out of the pram because Miles hadn't gone through them. So the Army weren't allowed to have it! However the type was used later by the RAF who bought 21. A total of 93 were produced 1942-48, including exports to 9 countries. It had huge rear-wing flaps which gave it the very low stall speed of 25mph! (cf Fieseler Storch stalling speed 31mph.) The engine was a Gypsy Major. Lord Tedder and Monty each had one.

[@senioravocado1864]

Tandem wings are real cool

[@LukeBunyip]

These appear as if they could have been the inspiration for some of the aircraft designs that Gerry Anderson et al came up with for "Thunderbirds"

[@jkorshak]

"Preference for Litho-braking..." 😂🤣 That was pretty good.

[@Gremlin23]

I suspect the M35 was the inspiration for the main aircraft in the Crimson Skies video game. What I am very curious about, though, is how this design would fare if you slapped a jet engine on it.

[@ThorneyedWT]

I wonder how they solved stability problems (which were main fault of XP-55 and all similar planes). Normal airplane's center of mass is situated within tight limits of wing lift force and then far behind tail pushes down to balance weight and lift. When nose goes down, tail gets even more downforce, if nose goes up, tail can get some lift - in both cases returning plane back to straight flight automatically. But tandem wings are exactly what they are called - wings, they both have to produce lift. XP-55 front stabilizer in fact also should be considered wing. And plane can't balance itself this way, any change in pitch suddenly results in more force pushing in the same way. Pilot can keep plane straight with constant corrections, but that is extremely exhausting and will make it impossible to fly without good visual points of reference. Modern planes use that scheme for various benefits, but they have electronic systems that keep correcting flight without pilot even noticing. But in 40s those systems would be impossible to make.

[@duaneharnes]

I imagine Burt Rutan took inspiration from these designs, and took it to a whole new level. Happy holidays to all!

[@mbryson2899]

Thank you for sharing your excellent research and presentation. Subjects such as this one help me understand all the ideas that were being explored.

[@duncangrainge]

Miles flew from Woodley Aerodrome not actuallyReading , just outside. Originally Miles did have a design office in Reading, in Donnington Road. The Miles factory building is still in Woodley but is now an automotive factory. Please see the great book Wings Over Woodley for the full history of the Miles Aircraft Company.

[@shero113]

I noted your oblique reference to the Miles Messenger, and how Miles went around 'channels', to the point the project was almost cancelled. Thanks for the video, and that amazing footage. Excellent research.

[@barbarybar]

Would have worked well with early jet engines. Two at the back of the fuselage side by side. Short inlet and exhaust helping to reduce thrust losses. Also an engine out would not have effected asymmetric thrust.

[@peterjohnson6273]

Always impressed with the work you do, Rex. Thanks.

[@johnjephcote7636]

I was brought up on many immediately-post-war photographic books and the Libellula was described in one of them. I have always admired the Miles team and became deeply interested in their innovations culminating in the harsh dealings by officialdom of their M 52 supersonic jet (to be piloted by Capt. Brown). I remember the 1947 adverts for the Miles pen company (the biro) into which The company had rapidly morphed. (Officialdom also 'took down' Frank Whittle's Power Jets company, desiring their own National Gas Turbine stablishment).

[@philsharp758]

Officialdom's treatment of Frank Whittle was an absoloute disgrace. I suppose going up against vested interests like RR and showing them that their entire piston engine production was obsolete, didn't help matters.

It behaved exceptionally well. except for the part between taxiing to take off and being back on the ground. But I really enjoyed the looks of the B variant. Nice one. Can't wait for your deep dive video. Especially to learn about the thing that looks like the Lancs weird cousin :D

[@sjsomething4936]

We have one of the 2 airworthy instances of the Lancaster at an aviation museum near my home, it flies over several times during each summer and every time I still run out to see it in flight. I’d go for a flight myself but you have to be a platinum member and the cost is in the thousands of dollars Canadian (for an hour) to be at that level. I can only imagine how amazing it would have been to see hundreds taking off from airfields in England at the outset of Market Garden.

[@stretch3281]

Nice to see Miles getting love. Reading is the town of my birth so I've allways known about them but it seems not meny people do, tho that would be very different if our government had let the M 52 fly instead of selling out to the Americans 🤬 P.s. Merry Christmas 🎅 🎄

[@grahamepigney8565]

My father worked for Miles at Shoreham Airport in the '60s. He was scathing about how Miles technology was exploited (some would say stolen) ranging from the M52 to the Aerovan. Miles produced various design in the '40s, of which the M35 & M35 were but two. They also produced an "emergency fighter" the M20 which performed nearly as well as the Hurricane IIB despite having a fixed undercarriage.

[@mr.fredricklawngtawnghedav5094]

Woww! Animation! This channel is getting better and better!

[@jenniferstewarts4851]

we still see the occasional tandem wing designs today, thought they rarely go beyond testing. The tandem wing also shows up in designs for "quad tilt rotors" where the tandem wing allows for the rotors to be placed at the 4 corners of the aircraft such as in the Curtiss-Wright X-19

[@Calilasseia]

And, it's notable that several modern jet fighters have effectively revised the concept. The Saab Viggen was an early example, followed by the Saab Gripen. Likewise, the Dassault Rafale and Eurofighter Typhoon have adopted, in effect, the same aerodynamic layout. I suspect aviation enthusiasts could provide a substantial list of such aircraft, apart from the four I've mentioned. :)

[@Snobiker13]

The Viggen works much the same as the Miles designs, while the Gripen, Rafale and Typhoon are more like the XP-55. The failure of the XP-55 could maybe have been prevented if they had a more advanced control system.

[@johnshepherd9676]

Kelly Johnson's 1939 L133 supersonic fighter design had a similar design with a much smaller canard replacing the front wing. As a design it was well ahead of it's time but I doubt that there was a powerplant with enough thrust to exceed Mach I until the early 1950s.

[@sadwingsraging3044]

Always loved the Miles designs. They, even if unconventional, are pleasing to the eye in proportion and shaping. Can't wait for the longer video on the entire company!🥤😮🍿

[@sjsomething4936]

Thanks for this video, I find it really interesting to hear / see some of the designs of aircraft (and other vehicles etc) that didn’t come to fruition.

[@PaulMcKendrick]

Fascinating!

[@z_actual]

This pair of aircraft were never 'tandem wing' which explains why the CG location was misunderstood. These are relatively straightforward canard aircraft where valuable lessons were learned. Among which the rigging of the CG, the placement of a canard higher than the mainplane, and the use of flaps. The CG if improperly rigged forward as in an emulated tandem, makes the aircraft too responsive to the canard, and with the mainplane in the wake of the canard the flying qualities would be difficult to understand. Once the CG was moved aft, the aircraft behave more normally and more predictably. Even better as on M-39 when the canard was moved below the mainplane, the downwash would no longer interfere with the wing by creating a flow with a negative airstream angle, and all those negative effects would evaporate. Neither of these aircraft would be suitable for carrier operations however, as canards usually demonstrate very poor short field performance unless very light, which warplanes are not known to do.

[@papalegba6796]

Good comment, thanks.

[@amniote69]

Miles aircraft also worked on Britain's attempt to break the sound barrier. That would be an excellent subject for a video.

[@papalegba6796]

Not sure if the proposed engine could break the sound barrier in level flight, but otherwise it was a sound design. Better than the DH Swallow anyway.

[@grahamepigney8565]

@@papalegba6796 The M52 was more than capable of breaking the sound barrier. Engine and airframe development was cancelled and the technology handed to the USA in the guise of the Bell Aircraft Corporation. Thus it went the same way as the swing wing technology which the UK government abandoned with the US government picking up Barnes Wallis's theories for nothing.

[@WilhelmKarsten]

The Miles M.52 scandal was one of the most shameful and humiliating chapters in British aviation history... Miles Aircraft was charged by the Crown with 24 counts of fraud and embezzlement, Frank Whittle was removed from Power Jets Ltd and discharged from the RAF amid allegations of extortion and dereliction of duty. Ministry auditors raided Miles Aircraft and found nothing but incomplete drawings and a partially built wood model of the cockpit layout, nearly all of the funds hadbeen stolen by Miles Aircraft and Frank Whittle.

[@WilhelmKarsten]

​@@grahamepigney8565 Unfortunately that is completely false, no aircraft powered by a obsolete centrifugal compressor turbojet has ever reached Mach 1 in sustained level flight, the are simply too inefficient for supersonic flight.

"Lithobraking" remains my favorite aircraft euphemism. These tandem-wing designs are so fascinating. I wonder if Miyazaki Hayao (of Studio Ghibli) ever saw that modified Lysander, or if his predilection for tandem-wings comes from their resemblance to insects like the Odonata order.

[@philliprobinson7724]

Hi. Thanks for this video, great old footage. I've made many flying model aircraft, canards and tandems, hoping that having two wings supplying lift rather than one would make for a more efficient plane. None were complete failures, but only one produced the desired results. It thermalled beautifully, rising up like a bird on the wing, and I never saw it again. So much balsa, so few results. Back to the drawing board---. Cheers, P.R.

[@SephirothRyu]

With my limited knowledge of wing airflow, I have to wonder if it would have done better had the forward wing been on the bottom and the rear wing on the top. That front wing would have been dumping its downward airflow directly onto the rear wing's upper airflow. ...Oh, looks like that happened with the bomber prototype. And indeed it sounds like it did a LOT better.
