The problem with swing wings that will permanently make them suboptimal is the weight of the swinging mechanism, which is in most designs substantial. Things like the oblique wing where there’s a lot less weight lost to mechanism are much more promising than traditional swing designs.
Wing form was likely examined in detail from this experimentation. Air pushing on air with a mass in between. F15 and X15🤔 Ames Research Center modeling?.. space shuttle design😊
I am a struggling aeronautical engineering student. Your videos keep me motivated in my darkest moments,
Yet another tech that was designed to kill and is now used for mankind's progression and benefit. I do think that the future of self driven cars involves some kind of infrastructure on the roadways themselves
The transition to the sponsorship always is great... Thanks for that gem!
Grumman!
You know how the US and UK beat Germany in engineering? They employed German-American & German-British engineers 😂
The Tupolev is so beautiful.
Always good to see you Paul. Big up on beating cancer you GENT!!
While this was uploaded about a day ago (4/30/2024), the video is approximately three years old. Now I remember why I unsubscribed.
Busemann has two meaning in Norway. Booger or as a direct translation, boogermann or as most people know him, boogeyman.
Hangar queens❤
well done. thank you for all the work and then sharing.
very interesting. I learned a lot (as has been the case on all of your other videos). Thank you for all the work and then sharing.
Indian orbiter has taken images of landing sites, can see everything left behind. No need for them to photoshop anything.
Thanks Paul, another great video. Now I'm off to binge on Panavia Tornado stuff!
How the hell do they take pictures of the ultrasonic shockwaves in flying airplanes?
Its called _Schlieren photography,_ invented by German scientist August Toepler.
Amazing that this design went out of production THAT early - given the service life of many of these jets (and especially the Tomcat being such an icon of the 80s) I didn't realise how very old these designs were. Btw. I appreciate how you pronounce Luftwaffe correctly, and want to offer some advice for other German words: What you see is what you get in many cases, meaning the vowels are usually pronounced just like in the phonetic alphabet (as well as the Romance languages). ;)
Electric tank would change everything
I wonder how they would have fared in Vietnam
The British team working on the supersonic plane had noticed - independently of Busemann - that the wings should be swept backwards because of the shock wave.
Please link a source???
Swing wing was and is heavy maintenance which obviously makes the cost of maintenance really high. Super high maintenance cost is 1 big reason why the F14 wasn't upgraded and was retired
Look at the maintenance, they were Hangar queens
Thank you, for this look at the arrival and disappearance of swing-wing aircraft.
7:35 Braunschweig Labs?
The RLM's _Luftfahrtforschungsanstalt_ at Brauschweig was built in 1935, it was the world's only large diameter supersonic aircraft wind tunnel laboratory. britain did not begin construction of its first supersonic wind tunnel facility at RAE Bedford until 1947.
Thanks for all you do! ❤ hope you are doing well
there is an rc plane that achived transonic speeds using a straight wing while dynamic soaring. it's called the Transonic DP and the pilot is Spencer Lisenby.
Yes, but the Renolds number is scalar, drag increases with size. Real planes have higher drag relative to their size.
Russians assembled one airframe that they had in storage since the collapse of the USSR. They don't have the tooling to manufacture more airframes. You are a fool if you believe anything they announce.
Having worked on the Tornado for a few years I would speculate that the reason for variable geometry wings fell out of favour was the complexity of the swing wing mechanical and hydraulic systems, especially the hydraulic system, and why do I say that?, well plainly speaking it was a complete pile of 💩 to get at, remove and install components and a complete sack of Sh1t, but that is just my opinion and probably has more to do with advancements in aerodynamics and technology systems. Out of all the “swing wing” aircraft types built the best looking is the B-1B Lancer/“bone” it just looks fantastic and vicious, something that it definitely is, and it will be a sad day, for aviation enthusiasts, when the bone is finally put out to grass.
Swept Wing Tomcat: I am cool and the greatest Delta Trapezoidal Diamond on F22: Bonjoir Diamond Wings on YF23: Yooo
The Me262 does have swept wings, but people who have studied the development closer claim it is due to the engines becoming heavier and a need to swift the center of gravity/lift rather than high speed flight.
That claim comes from a single, highly dubious source... it is based on the authors lack of understand in the difference between the RLMs _Projekt 1070_ (which was designed with straight wings and was cancelled) and the _Projekt 1065_ which was designed from inception to have all swept lift and control surfaces and was adopted as the Messerschmitt Me-262. This false myth is easily debunked by the fact that the CoG can be easily changed by repositioning the engines on the wing. and the fact that the Me-262 flew with 1, 2 and 3 engines, many different engine types with different weights and CoGs from many different manufacturers with NO CHANGE in the wing sweep angle. Adolf Busemann designed the 1065 and tested it to speeds up to Mach 1.4 at the _Luftfahrtforschungsanstalt_ the only supersonic aircraft wind tunnel test laboratory in the world during WW2.
The Carreidas 160 was the only civilian jet with swing wings. 😜
youtube hid this from my notifications. I had the bell on and everything.
10:30 The Swallow looks like something out of Looney Tunes. The pilot was Marvin The Martian 🤣
Vickers only built a single jet aircraft it it wasnt even supersonic...
I always wonder, when the main wing is swept back to the second, how BAD the resulting flow is over the combination.
All the advances in engines and aerodynamics could still be applied to a variable-swing aircraft, and it would still have much wider flight envelope everything else being equal. Because physics. Variable angle is not free, but neither is NOT having it. While fixed-angle is cheaper to build, it either cannot attain the same high speeds at all altitudes (F-22 cannot come close to the top speeds of F-14 despite much newer engines), or cannot fly as slow, or (as in most real examples) BOTH. The latter (lack of low speed) costs you dearly as you need longer runways, For Navy aircraft it means you need supercarriers instead of regular aircraft carriers (SO EXPENSIVE!) and much more powerful catapults and arrestors, necessitating heavier running gear. Also without low speed capability you NEED all that unsustainable high G’s to make tight turns, and I don’t care how well you are trained and how good your pressure suit is, at 9g you are not lasting more than a few seconds and still cannot avoid modern missiles with 30g and lateral thrust.
Not only the B-1 and Tu160 remain in service, but I see Panavia Tornado's flying over my house on an almost daily basis. They are of the German Luftwaffe.
Hold on... "Soviets produced 10,000 swing wing aircraft, and the U.S. produce [about a thousand+]" ? Somebody is taking Khruschev propaganda a little too seriously. What is your source?
Somebody didn't read his history books. Khruschev was long gone by the time the Soviets even began mass producing swing wing aircraft.
You guys should do one on China pumping out that MASSIVE Modern Stealth 🥷 Air-Craft Force 😮
swing wings were a great idea but... it was a complete maintenance nightmare. The F-14 needed 40-60 hours of maintenance after every flight. The B-1 need up to 168 hours after every flight. The F-111 required 187 hours after every flight. Compared to the F-18 10-20 hours depending on model. F-16 17 hours, F-15 20 hours, the F-35 9 hours.
Staggering numbers, if true. What would they be doing?
To be fair, those extensive maintenance hours on the F-111 weren't because of the swing-wing design, but mainly because of the leading-edge technology in its avionics systems. I worked in-shop, avionics repair for 5 years. Very complex systems, tied together to provide unparalleled navigation and flight characteristics. You had inertial navigation tied into doppler RADAR and star-tracking nav systems, along with individual roll, pitch, and yaw computers, the terrain following RADAR and attack RADAR systems. When it all worked it was amazing (I have seen photos of a practice bomb leaning against the 'ground zero' pole marker, with it's drag parachute draped over the top of the post). There's a reason that the Aardvarks won many SAC Bomb/Nav competitions, and also destroyed more tanks in the middle east than the A-10 'tank killers'.
Just to clarify, 56-57 Swallowtail design @ approx. 11:00 because U.S. DoD didn't approve. It was because it was completely conjectural. It was the wrong place to put money. Tail-less and without surface controls would not be even possible until computer control had advanced by decades. In the 50's and 60's computer tech's possibility wasn't even comprehended by serious, hard-working, and advanced engineers. It was pie in the sky. There were at least 20 more deserving places to put money that had promise of delivering national security. Even now, with 20/20 hindsight, the design was not viable and doesn't exist. It would have gotten a lot of people killed.
I must be remembered that Vickers had absolutely no experience building supersonic aircraft and only built a single jet aircraft... the Swallow is clearly nothing more than wishful thinking.
The answer could be told in 30 seconds... And the british patriotism is... overflowing, to be polite!
The F-14s wingbox is made of titanium and is difficult to manufacture. One of the main issues with swing wing design is the wingbox.
no one does swing anymore, the new craze is rap pop.
'yo un', TERRIBLE. Or even WORSE: electronic pole driving noise.
The swallow looks like a flutter disaster waiting to happen.
12:02 Man he absolutely carved that part into his head
I imagine the biggest problem with swing wing is when the wings move back the centre of lift also moves back and the trim has to be adjusted. Presumably it's most in balance in at the most commonly used speed and setting.
Why all that blabla from the 1930/1940 …
Here’s my two cents. The Iranian regime is corrupt. This means the people building the bunkers, the materials put into the bunkers, and the methods of building the bunkers are likely compromised. Look at the buildings in China which just fall apart well before they should. I think the US weapons are overbuilt, expecting the best possible enemy defensive works- like the F-15 was an overreaction to the Foxbat. I have a feeling the Iranian bunkers are more propaganda than effective.
You're an excellent writer Curious, love your work!
