Hi Paul! I’ve been watching your channel for many years and absolutely love the videos you make. I think I’ve seen all of them! Your style of presentation, speaking voice, impartial approach, article research, shirts, and obviously topics of interest have kept me watching. That said and as much I do actually enjoy Ground news, the segways in to the advertisements have become a tad more jarring as of late. Maybe it’s just me, maybe not. Perhaps a poll would help 🤷🏼‍♂️ In this video, the transition was so seamless that I actually skipped it immediately as soon as I realised. My suggestion and something I’ve seen work on other channels, is to include a little info box that states ‘Advertisment’. It lets the viewers know that the information now on screen is NOT the subject matter, and tunes them in to what you’re saying about the advertisement, and might lead to more conversions to the sponsor link. Maybe 🤷🏼‍♂️ Just a thought. I might be wrong.

TB1 was actually a swing wing design and they made a marvellous overhead shot of it deploying the wings to their forward position for the first ever episode.

On the F-111 aircraft, we seldom had any maintenance issue regarding the swing mechanism nor the items to accommodate it in the fuselage. Yes, we had major wing carry through box issues early on, but the design was sound, just the issue of welding embrittlement bit us in the butt, big time, and we lost a few crew, unfortunately, again, early on. IIRC (I was an Aircraft Production Superintendent) at most we had to keep an eye on the over wing fairing systems, but it was never, ever a chronic issue like some of the early avionics and stab actuators, just a check for wear on pre & postflights.

That is not true. 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, 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.

@gort8203

Ай бұрын

If you think swing wings have been surpassed you misunderstand their purpose. There isn't a non- VG aircraft that approaches the aerodynamic efficiency of a VG wing over a wide flight envelope. Quite literally the aircraft gets to use a different wing for the flight regime in which it is operating at any given moment. Bombers like the F-111 and B-1 had swing wings because they can lift more and fly further while retaining the ability to go very fast when necessary. You can go that far with a big high aspect ratio wing or you can go that fast with a small low aspect ratio wing, but you can't do both with a single wing. Aerodynamics didn't change, the mission profile changed.

Furthermore, the Lightning has a higher thrust-to-weight ratio of 0.74 compared to the F-104's 0.54.

The Tomcat is my favorite of the swing wing aircraft. For a big aircraft is was quite maneuverable at low speeds with the wings straight. It had the first microprocessor (custom made) that controlled a flight computer that governed the wing sweep. The Tomcat's wing sweep was automatically set by the computer based on aerodynamics at any given moment. I would imagine the hinged design limited their max g more than what later aircraft like the F-15 and F-16 were limited to. And there was more maintenance required for them than ones with a fixed sweep or delta wing.

Swing-Wing aircraft CAN accelerate through the Mach and transonic regime like few others can, given the same amount if thrust/weight ratio, a swing wing will blow the doors off an equivalent fixed wing jet, except deltas. (Which can't land anywhere near as slow). Bottom line: Delta is the best. Swing-wing performs similar at high mach. But can land far slower and handle better at low speed.

@HappyBeezerStudios

Ай бұрын

Yeah, the low speed performance of a straight or back swept wing and the high speed performance of a delta wing. That is flight performance, not carrying performance. The weight of the swing mechanism is weight that can't be used for bombs or fuel, so a swing wing design will have less range and/or payload capacity than a fixed wing design. Plus the mechanic means higher manufacturing and maintenance cost.

I would contend that advances in aerodynamic design actually had very little to do with swing wings disappearing. Most swing-wing aircraft actually had more complex flaps and slats than the fixed geometry aircraft that replaced them, often including double and triple Fowler flaps and real slotted slats instead of just leading edge droop. Leading edge extensions that many modern fighters have their roots in the wing gloves of swing-wing aircraft and the double delta of the Sweedish Drakken from the same era. The F-14 was the odd one out as the only production swing wing air superiority fighter or interceptor, and only because as a naval interceptor it needed to combine an interceptor's speed with long loiter times and unrefueled range. the F-15, which was designed around the same time for the same role, except for the airforce, which has much more refueling capacity, had no need for swing wings. Basically every other swing-wing aircraft was a strike aircraft designed to fly fast at low level to avoid radar. The faster you go, the bigger your wings, and the less sweep, the more turbulence throws you around, so going supersonic under 500 ft requires extremely small and highly swept wings so the aircraft stays controllable and doesn't exceed its G limits going that fast in low-level turbulence. The F-105, which was the last pre-swing-wing plane to play that role had a takeoff and landing speed of around 230 mph, a full 100mph faster than the swing-wing aircraft that replaced it. swing wings both increased lift for takeoff and landing themselves and allowed extreme flap configurations to be mounted so that they could takeoff and land at forward bases with less than 6000 ft (2000m) of runway. It also made low-level supersonic strategic bombers like the B-1, Tu-160, and Tu-22 possible at all. Just as an interesting aerodynamic note, the concord represents about the maximum size for a supersonic aircraft without a swing-wings regardless of its engines. large aircraft have to use delta wings because blade-like wings don't have enough bending strength. those delta wings (with or without a tail or canards) have a significant bleeding edge angle, so as the wing gets bigger, its span and area is limited by how long the wing root is. Because area scales with length squared while volume scales with length cubed, if you tried to get bigger than the concord with a delta wing, the wings would have to be longer than the plane, which obviously doesn't work. What killed swing wings from a military perspective wasn't improving aerodynamics or engines so much as improving electronics, mostly for cruise missiles that could do the same job better and with less risk without having to worry about takeoff or landing.

@jj4791

Ай бұрын

That's a great comment, lot's of detail. But I disagree (slightly). The reason the F-14 needed a swing-wing was for mach 2.4 performance while being able to land on a carrier under manual control of the pilot directed by a signal officer in all weather. It had to get slow. And it had to go fast. And it had to do both with a heavy weapon and fuel load. Swing wing is practically the only way to make this happen. No naval jet can reach or exceed mach 1.6-1.8 without swing wings.

Interestingly, I never heard of this story. In spite of being interested in US/Soviet relations, fall of the wall history, and a fan of general aviation. Based on my amateur/armchair psychology, I would say this Rust person might be a psychopath. Clearly a driven and motivated individual accomplishing interesting feats. Clearly lacks regard for any and all laws. Or of any real dangers of reality itself. Lacks any and all empathy, stabbed a female co-worker for rejecting him. His parents appear to have sold his exclusive story before he arrived back home. What kind of parents would capitalize of their captured son before he returned? (Bad mothers/not good enough mothers, see Prof. Sam Vaknin for a professional explanation on how this is the driving mechanism which creates Psychopaths).

A very concise and through presentation. Thanks.

Really enjoyed this 1. I loved the swept wing designs.

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.

If it works, it works. It takes time for a new, cheaper to maintain plane to balance out the purchasing cost.

Weight and stealth requirements is my best guess.

Nope. Maintenance costs. The F-14, for example, requires 50 hours of maintenance for each hour of flight time. This trend continues today with the B-1B being notoriously difficult to keep flying with lower readiness rates compared to the B-52 or B-2

indeed... the Swallow was pure science fiction.... Vickers never built a supersonic aircraft, it only made a single subsonic jet.

hope your health is good. cheers. watching now 1m after publishing and im sure this is wonderful content as always.

One thing not mentioned in this video about 'swing wing', and I'll make this point specifically about the F14... I have learned a lot about dogfights by watching DCS videos(specifically: Growling Sidewinder(aka: GS)). GS loves the F14, however, when GS dogfights against the F14 he points out certain things about it, specifically: you can get a pretty good 'read' on how fast the F14/swing wing aircraft is flying based on the geometry of it's wing(ie, the F14 is slow when it's wings are straight and fast when it's wings are swept). This is very good information if you are the adversary aircraft(knowing the approximate speed of your enemy aircraft allows you to make the correct maneuvers to put your aircraft in an advantageous position to kill your enemy). somethingtothinkabout

13:51 He finally gets to the point and vaguely answers the question. The video would have been a lot more interesting if they'd focused on answering the question and detailed HOW swing-wings create stability and HOW active controls do it better, leaving stealth to be major design factor. It's such a shame and rather frustrating when a title poses an intriguing question but then content barely addresses it.

wow, nice video ... very informative

Always educational 👍

1974 was the b1A. Which was killed by Carter. Reagan brought the program back which was redesigned as the b1b Lancer, which wasn't as fast at high altitude, but had faster low level dash speeds

Paul, Thanks for all the hard work you put in to these videos. I tried Ground News but dropped them after they identified AP and Reuters as Right of Center. For funding, you should start selling the shirts you wear in these videos. I haven't seen the same one twice and they are all cool enough to command a great following. Cheers!!

This guy covers *the most interesting topics ever!!*

I remember hearing that the F-111 was 9% of the Gulf war air fleet but accounted for 25% of the maintenance costs. Cost aside a double delta wing or wing with leading edge extensionsis basically the same but way easier to build and design

The X-1 also that the benefit of a TWR sufficient to overcome the missive transonic drag of its design. With its shape the biggest problem was that it did not have area rule incorporated in its shape as much as its straight wings.

F-16 is such a monumental achievement that even today, 50 years later remains the top dog.

In 1974, it was the B-1A design not the B-1B. I was at Edwards Air Force Base when a B-1A crashed in the 80's. That crashed is what led to the B-1B.

Thank you!

Since as a kid a love how the F14 tomcat looked and had a toy with a swing wing that was so cool up until now. But as I grew old knowing the more moving parts are there the more headaches to deal with.

i missed him so much, glad hes back!

Great presentation. Minor nitpick: The US B-47 bomber was the "Stratojet," not the "Stratofortress." The "Stratofortress" name went to the B-52. A major problem of swept wings manifested itself on the B-47 as a consequence of the relatively low output powers of the jet engines of the day. If they'd stuck to the original plan of a straight wing, the jets chosen might have done the trick. Sweeping the wings -- combined with comparatively low-thrust engines by modern standards -- meant for some absurdly long takeoff distances, particularly at airfields at higher altitudes. The solution was "JATO" or "Jet Assisted Take-Off," which essentially added rocket engines that would only be fired at takeoff. Not an optimal solution, however, since the JATO bottles were themselves heavy and they had to be positioned uncomfortably close to parts of the airframe in which fuel was stored. The eight-engined B-52 corrected the thrust problem and caused the B-47 to fall by the wayside pretty quickly. An officemate of mine who was some years my senior remembered being a crew chief on the B-47 in the 1950's, when it was still regarded as an option for use as a strategic bomber over Soviet territory. But he used to comment that he was on a few of the very last runs of the B-47 when it actually still carried bombs. By the mid-1960's, the B-52 was carrying the bomb payloads and the B-47 had been relegated to other tasks such as photoreconnaisance.

Two uploads in a week, whew. I usually watch these 3-4 times to absorb everything, going to turn into a daily routine. 😂

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). ;)

The title is not quite correct. Swing wing aircraft ARE still being made. The Tu-160 is still in production.

Even as an F15 guy, there is something so cool about an F111 or F14 or Tornado with it's wings all the way back!

It takes a-lot of work to look this good.

I had a toy F14 Tom cat and just folding it's wings was the coolest thing. I remember that clearly. I even had a F18-hornet which had a wired remote control. 😂

Still using the B-1B. It’s still working. It’s still awesome.

A big factor was also low level operation during the cold war. It is no great surprise that most of the swing wind aircraft were air to ground. The swing wing allows them to move from a low wing loading for shorter take off and landing to a higher wing loading for smoother low level flight. The pinnacle of this was the Panavia Tornado which, as well as swing wings, had slats, full length double slotted flaps and thrust reversers to aid with short take off and landing as well as fly by wire to allow smother low level flight at very low levels.

Lifting body shaping is part of modern fighter design

Fantastic as ever.

I want to build a line of folding wing amphibious aircraft, so they can utilize most boat docks.

Thanks for answering my questions about the loss of swing wing aircraft 😎

Great presentation. Just a correction, the B-47 was the Stratojet, the Stratofortress was B-52.

The 010 by Vickers is beautiful, but with the engines on the wing tips-good luck landing it if one of them fails...

It was really more science fiction considering Vickers had only ever made a single jet aircraft and it was unable to fly supersonic.

High performance hang gliders are slightly swing wing. The angle of the wings is swept slightly further back for takeoff and landing which increases washout and makes stall more forgiving and makes it more manoeuvrable.

Damn, that frontal view of a white TU-160 was gorgeous. Somehow I’d only ever seen side profiles of them before now.

The Vickers Swallow removal of control services was done by vectored thrust not variable wings. The four engines where vectored similar to rocket engines for control authority.
