From the mid-60s up to 1981, swing-wing aircraft led the way for new multirole aircraft that combined the low-speed stability and efficiency of a straight wing with the high-speed performance of a swept wing and led to some of the most famous fighters and bombers of the 70s, 80s, and 90s. But from 1981 onwards not a single new aircraft was built with a swing-wing design. In this video, we look at why this happened.

      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.

      I doubt it. Swing wing aircraft usually need hydraulics in order to move the wings. Military aviation hydraulics need to withstand extreme heat and cold. This means that military aviation hydraulic liquids are usually some of the most toixc cancer causing chemicals known to man. They are very dangerous to work with during maintenance.
      An F-22 might take longer to service, but at least you don't have as many moving hydraulics parts as an F-14.

    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.

      The 'carry through box' issues were eventually solved by RAAF engineers, who figured out how to do a Carbon Fibre Overwrap on them, so the CF took the stretch loads and the metal took the compression and flex loads. It's the reason why the US tried to force a sale of the Aussie jets back to the manufacturer, to pull the boxes apart and try to reverse engineer them. Story goes that when the jets few back to the US for some maintenance tasks, the original boxes were refitted, as the Carbon over-wrap technique used was classed as a National Secret at the time.

      The English Electric Lightning seems superior to the F-104 for several reasons. The Lightning reaches Mach 2.3 compared to the F-104's Mach 2 speed. Additionally, it boasts a larger wingspan of 10 meters, providing better stability and maneuverability, compared to the F-104's shorter 6-meter wingspan. Furthermore, the Lightning has a higher thrust-to-weight ratio of 0.74 compared to the F-104's 0.54. It's puzzling why the F-104 was designed with its stubby wings if it doesn't achieve higher speeds than the Lightning.

      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

      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.

One thing I found interesting about their development was that they needed very robust vacuum tubes that could survive impact with the water after the torpedo was dropped from an airplane. Instead of glass envelopes they were placed inside of cavities machined out of a metal block, and the filaments were overdriven to reduce warm up time so they could be lit immediately after hitting the water

    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.

    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
      @jj4791 20 วันที่ผ่านมา +5

      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.

    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
      @HappyBeezerStudios 3 วันที่ผ่านมา

      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 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

    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.

    My first thought is "They are complex, heavy, and expensive"
    Sure, it can have different aerodynamic modes, each with it's own optimal speed area, but all that mechanical stuff has weight, weight that doesn't do anything for the plane when it's not changing the wing mode. Weight that could be used for more fuel or more payload.
    Lots of bits necessary to maintain the mechanic. So more different replacement parts need to be manufactured.
    All that increases cost. You need more planes to deliver the same payload and each of these planes is more expensive to build and maintain.
    And then obviously the fact that modern jets aren't build to fly at the same speeds.
    Intercepting duty is done by missiles, so no need for those huge speeds and climb rates. Close range dogfights are exceedingly rare, so no need for extreme slow speed manoeuvrability. (Some even suggest omitting the nosegun for that reason)
    And what we see nowadays are delta and trapezoid wings, which are fine from slow speeds up to slow supersonic flight. Exactly what modern jets do.

    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.

    The whole point of swing wings was so you could go supersonic at low altitude , survive the turbulence and still be able to land at a safe speed.
    If you were hauling at mach 1.2 just 100 feet above the ground to avoid radar , you needed small wings that wouldnt slam the aircraft with 15G bounces when you hit the kind of turbulence you see at 100 ft.
    But wings that small wouldn't be able to take off with a heavy payload
    So the F-111
    Then cruise missiles got good and took over that job.
    The F-14 was a high speed interceptor to carry a lot of long range air to air missiles extremely fast and still be able to land on a Carrier.
    Then the SM-2 got good.
    The reason swing wings went away is because missiles took over the jobs they were doing.

      No way, VG wings are far more efficient than fixed wings, which have to compromise for the portion of the flight envelope where they need to be most efficient. The F-15 wing was designed for maneuverability at high subsonic speed, but it is not as efficient during cruise or dash as a wing that can reshape itself. VG didn't make sense for the F-15 mission but made great sense for the F-111 and B-1 mission. Aerodynamics didn't change, the mission profile changed.

    • @batmanjones655
      @batmanjones655 18 วันที่ผ่านมา

      VSW's may be more efficient aerodynamically. They may even make sense in the small picture. But not in the big picture. Delta/hybrid wings can fly low speed approaches now because of advanced FBW. Not to mention TVC when it comes to maneuverability in high and low speed regimes. Why do you need all the added weight, moving parts, and single point failures of a VSW when a more effective solution has been found and implemented? It was a great solution in the 70's when they designed them. We just found better solutions. So no, aerodynamics didn't change. But the entire paradigm of high performance flight did.

    • @gort8203
      @gort8203 18 วันที่ผ่านมา

      @@batmanjones655 Not “may be more efficient”, they are more efficient. And a simpler solution has not been found-if you think that you do not understand the actual problem VG wings solve. Forget maneuverability, we're not talking about making a better dogfighter. The F-15 looked at VG and discarded it because the extra weight was counterproductive for sustained maneuverability in the part of the envelope for which they optimized the wing, and total efficiency across the entire flight envelope was less important. The F-14 didn’t have a VG wing to make it a better dogfighter, it had a VG wing to meet the fleet defense mission requirements of a heavy load and long endurance coupled with high-speed dash. A fixed wing optimized for dogfighting could not do all that. The mission drives the wing.
      TVC is about controllability at low speed and has nothing to do with subsonic efficiency beyond allowing for smaller control surfaces. Delta wings can fly at low approach speeds without FBW, which has nothing to do with it. The delta wing is very inefficient at low speed.
      The added weight of a VG wing pays for itself in less fuel carried to go a given distance. You lift more fuel off the runway and use less fuel per mile, allowing more payload and range, but can still sweep the wings back for high speed when tactics require. The added cost and complexity paid for itself in allowing a single aircraft to strike a target that would otherwise require multiple aircraft. More capable aircraft always cost more to obtain and maintain.

      ​@@batmanjones655 The pot calls the kettle black. You claim to understand engineering while you don't even see that thrust vectoring and FBW don't do anything like what VG does for efficiency. Thrust vectoring also adds weight and complexity, but unlike VG does not pay for itself by increasing the range or payload of the airplane, which is why it was not included on the F-35.
      TVC and FBW might allow a given design to eke out a minor increase in efficiency at a particular point in the flight envelope, all other things being equal (which they are not in a new design). VG allows an airplane to be significantly more efficient throughout the envelope. That efficiency alone pays for the extra weight. Better yet, the increased cost of VG was paid for by making the aircraft more effective in combat, allowing fewer aircraft to perform a given mission. You criticize my understanding, but it is you who does not read well and does not understand total efficiency.
      Your statement that FBW computers can allow wings like those on the F-15 and F-18 to outperform VG wings remains inaccurate. It indicates that you don't even understand the purpose of a VG wing. VG was not replaced by FBW and TVC; it was replaced by changes to combat mission requirements that outweighed aerodynamic efficiency.
