There are many types of aircraft wings aside from the current ones you are familiar with.. Well, maybe not the Star Wars X-wing fighter...not yet anyway. Some of these concept-wing jets are so bizarre that you’ll wonder how they even got into the air…
Check out the Grumman X-29 with its forward-swept wing, and canard control surfaces which some would call a bold innovation...if these can be called that at all. It was created during the height of the Cold War by the ‘men in black’ at the Defense Advanced Research Projects Agency or DARPA for short. NASA was also in on the game with the U.S. Air Force along with aerospace behemoth Grumman. It made its first flight in 1984 as part of a program to build the ultimate fighter jet.
It is the most aerodynamically unstable aircraft ever built. In fact, it was literally impossible to fly this aircraft without a digital flight computer onboard making corrections to the flight path 40 times per second! The engineers of the aircraft all came to the conclusion that if all three redundant flight computers, backed up by three analog computers, failed, the airplane would have broken up around the pilot before they had a chance to eject!
#aircraft #plane #jet #fighter #military #usa #army #navy #russia
The reason why a forward sweeping wing is so unstable is because the air, when passing over the leading edge of the wing, gets compressed where the wing meets the fuselage. Basically, the wings are scooping and sliding air in towards the center of the aircraft rather than back and away as with a rear swept wing.
The effect can be felt by placing your hand outside a car window while traveling. Stick your arm straight out and you'll feel the air build up on the leading edge of you arm as it tries to push you arm backward. Angle your arm backward and the air can pass down the leading edge towards your fingertips with little resistance. Now angle your arm forward in the direction of travel and you'll feel the air rush in towards your face. In an air chamber, this causes huge vortices at the connecting point of the wings and directly above the aircraft as the two vortices off the wings collide. The reason they are so maneuverable in flight is basically because the turbulence is essentially trying to push the aircraft downward which reduces lift. At very high altitudes with less air density, this configuration may work better but it'll never work as well as a rear swept wing.
Thanks for your explanation. I was wondering what, if any , reason why would want the wings swept forward. Seems silly and dangerous.
Keep arms inside car
It was already built.
Shouldn't the title be "Will the USA build another aircraft?"
It b awesome for china new nuclear missile
Not if the DEMONrat's take charge. KEEP TRUMP!!!

I love how he says Star Wars X-wing fighter after showing us a Z-95 Headhunter and an ARC-170.
What he says and what they show didn’t match up throughout the video
Shut up nerd

You missed one operational swing-wing fighter jet. The F14 Tomcat was a swing-wing fighter aircraft for the US Navy. It was a Mach 2+ fighter/interceptor.
Tomcats with F-110's!🇺🇸😁
Great aircraft the Tomcat but was not forward swept winged, it was swept or variable sweep wing rear ward.
F111 Ardvark
The F-111 was a most excellent fighter bomber.
Swing wing design and entire cockpit would eject if necessary to punch out at mach 2.
The Tomcat was rumored to conduct international diplomacy while inverted.......
Another cool thing about the f111 ardvark is it could dump fuel as the afterburner was going to create a massive fireball behind them. I believe it had worked on heat seekers before too
Not only could the US build a forward swept wing aircraft, but we have.
The X-29, who barly function, had big problems to have control, it near fall down several times, they didn't make to get control of the aircraft properly.
It is only the Russian Su-47 (Planned and blueprint's was made in the Soviet era), but do to bad economy after Soviet got dessolved, the, the Su-47 didn't come in the air before 1997, 7 years after the plan. But when it came in the air they had good control over the maneuvering, but was from the start only planned as a sole aircraft produced served as a technology demonstrator prototype for a number of advanced technologies later used in the 4.5 generation fighter Su-35BM and current fifth-generation jet fighter Sukhoi Su-57.
The Russian, German, Japan and even US buildt forward swept wing planes and fighters in the ww2. It was only the German Junkers Ju 287 and the Soviet's who who could have become a good bomber's.
The Belyayev DB-LK, a twin-boom design with forward-swept outer wing sections and backwards-swept tips. It reportedly flew well, maybe the best of them all? Belyayev's proposed Babochka research aircraft was sadly cancelled following the German invasion. The German Junkers Ju 287 was finished to become in the war, so they wouldn't make survive that late in the war.
I don't think US have the technology to make a proper modern forward swept wing fighter the first 20-30 year, they need to learn of the Russian, who also have a forward swept wing trainer, the KB SAT SR-10.
Iran will probably make several of both, forward swept wing trainers & forward swept wing fighters, before US will make to produse a prototype who maybe will could just as good as a F-5 Freedom Fighter
@@udontknowme7798 US built the X-29 in the early 80's, the two X-29s were flight tested through 1991.
@@udontknowme7798 The X-15 is the first hyper-sonic maned aircraft
The days of dogfighting are over. All that matters now is stealth, speed, censors and weapons platforms except navy complicating things with their STOVL-VTOL requirements.
@Ajay Singh it will all be beyond visual range and electronic warfare. Maneuvering reduces speed.
Yes they actually can. Remember the x-29 aircraft?
@ Irrelevant. He merely answered the title question. Could it be done? Yes, since it already HAS been done.
Yes in red white and blue.
FSWs are great if you don't plan on flying faster than 400knots without excessive drag / fuel consumption, you don't mind having an enormous frontal RCS, you don't want to ever have supercruise capability, or the ability to have multiple weapon stations on the wings, and you don't mind replacing the entire wing when they develop stress fractures. A delta or modified delta by comparison will provide adequate low speed handling, along with much lower transonic & supersonic drag, plus area to store internal fuel & mount weapon stores.
The Grumman X-29 was an American experimental aircraft that tested a forward-swept wing, canard control surfaces, and other novel aircraft technologies. The X-29 was developed by Grumman, and the two built were flown by NASA and the United States Air Force. The aerodynamic instability of the X-29's airframe required the use of computerized fly-by-wire control. Composite materials were used to control the aeroelastic divergent twisting experienced by forward-swept wings, and to reduce weight. The aircraft first flew in 1984, and two X-29s were flight tested through 1991.
And never forget the most famous forward swept wing aircraft of all time, Thunderbird 2
The X-Wing was built, but didn't fly as such (it was a kind of compound helicopter planned to be able to stop it's rotor in flight and fly as a fixed wing/rotor aircraft)
It flew using a pair of small wings, but not with its stopped rotors
No one gonna talk about how they used Kerbal Space Program in 10:21 for footage? Pretty resourceful!
Resourcefil in covering the fact that they didn't get a hold of any archive footage in time for compilation & uploading.
For those of you who don't know this guy actually for once knows what hes talking about......
Very refreshing to se someone who actually knows what there talking about,
Nice very nice👍.

Me that has watched macross. See the sukoi SU-47
Me: *YF 19 BABY*
stupid question... they already have.. and they discovered the inherent problems with it. the Grumman X-29.
Very stupid Question indeed; I have vivid memories of this experimental X-29 flying around in 1984. So 36 years later I am curious on who would've wanted to bring the Wright bro's design back; get a fucking grip people.
A Terrible Aircraft. Glad it was experimental.
The Soviets X Wing was a success. Alot better then our X29. They kept flying demos long after.
@Sparky Puddins Thank you, I checked it and it is there.
actually it performed better in maneuvering in extremes positions and turns. But since that is only utilized in specific conditions it wasn't enough to make up for its faults in normal flight. Such as needing flight computers to keep it airborne. Something somewhat related to the boeing 737 X if you will. We learned a lot in this experiment. The value of experimental aircraft doesn't always equate to a successful aircraft but it still pushes us forward in design. I suspect there will be a future aircraft/drone with forward swept wings to serve as wingmans.
Very little about forward swept wings, more about wing designs instead.
Remember to credit Kerbal Space Program.
I used to work for Grumman Aerospace back then when they were working on the X-29 FSW. I used to walk by it in plant 5 in Bethpage, L.I. when I was cutting through and just to see it. Apparently it was not a classified project otherwise I wouldn't have been able to do that.
Thought this would be exclusively for forward-swept aircraft.
Also the fact that he didn't mention the F-14 Tomcat while talking about swing wings irks my soul heavily
The U.S. built the X-29 in the early 80's which first flew in 1984, and two X-29s were flight tested through 1991.
It was so unstabile that they should be happy that they had "Fly by wire", ore they both would have crashed
The tails in planes are no longer necessary, they are evolving like animals, more like Sting Ray's and eventually tailed, using waves forms...
iirc, the X-29 was also designed to test composite construction and at least one was equipped with a Vulcan cannon, which shook the airframe to a far greater degree than expected, also, iirc, primary construction was by Burt Rutan's Scaled Composites company.
In the1960's Gerry Anderson's model designers, some of them went on to build models for Star Wars designed a famous fictional plane with forward swept wings. Thunderbird 2.
Ace Combat is slowly becoming real.
The US Built one of these years ago, it was good for Dog Fighting, but nothing else. The Gruman X-29 in the 1980's
I love the Clone Wars & Battle Of Coruscant clips at the start! xD It’s nice to see Clone Wars and the prequels getting referenced instead of just the original trilogy for once
CLONE WARS was an amazing story
"Not like the X-wing"
*Shows ARC-170*
Before you kids complain I know the Z-95 and the ARC-170 are the predecessor of the X-Wing
America has already built a FSW demonstrator. It's called the X-29A built by Grumman for NASA. So it's not "Could America build a Forward Swept Aircraft" It already has, and did so in the 1980's. It was also a fly by light demonstrator, and one of the first Aircraft to use computers to control airflow over the canards, with wingtips that were allowed to flux, or lightly twist, to help keep it stable in flight. Top speed was a reported Mach 1.9
We already have built one and it was called the X-29 and found that there were more problems than benefits like it was the most aerodynamically unstable aircraft ever built. The engineers concluded that if all three flight computers had failed together, the airplane would have broken up around the pilot before the pilot had a chance to eject. One study on the aircraft determined that the benefits did not outweigh the disadvantages and then stealth technologies came along. The Russians tried it with the SU-47 and found so many problems with wing stress that they scrapped the project and went back to traditional wings on the SU-57.
As mentioned we already have. So has Russia.
Russia... lol.... can all rsa can do... copy of German...
fucking ass is next rsa do best...
and Germany already at WW2 times hahahahahah
Could the US build a forward swept wings? You mean like the Grumman X-29?
The US developed the forward swept wing ages ago but never went into production. It was designed to improve the aerodynamic drag of the conventional wing and had some success but at high speeds, the stress on the wings were enormous and the aircraft became unstable as it could spiral uncontrollably at some point. The program concept was suspended until further technology of better (composite) materials could be developed to produce a better wing that can handle the drawback of flying at high speeds and tight turns without having divergence issues. The US airforce decided it was not a priority to develop agile fast speed aircraft such as this as advances in combat engagements shifted to concentration on thrust-vectoring aircraft technology and medium range smart missiles instead.
"could" is the wrong word.
Mediiiicc “have they built it”, is more accurate...
@@brianpayne4549 yes they have. This is youtube look it up. LOL
This type aircraft was built years ago and considered to be very unstable and could not be produced commercially because of that
We did.. And it was slow, and had an ever present threat of wing shear. The Grumman X29.
the x-29 was made so that the airflow around the wingtips was smoother, so that the plane could achieve supersonic speeds much faster.the main problem might have been the straight flaps on the back, or the thickness of the wings.
I wish we kept F-111. Make a modern version with stealth, swept wing, large fuel tank and high capacity internal weapons capacity. So this jet should be high flying fast and very maneuverable with Long reach and lots of weapons.
You'll have advantages with a swept forward wing, but recourse 1/2 the wings rear ward again, and the wings need to be made twice as strong.The 22;is fine For sweep forward designs round out your points on these and pull them back into the body.
They already did and that was the experimental plane X-29.
Been there done that , The X29 with fixed forward wings, and the Bird of prey with forward swept for dog fighting, straight for landing & swept back for high speed. The f-111, f-14 & B1-B have back swept.
We already made something like this, and with a V tail. The YF-23 blackwidow. Probably the sexiest airframe ever. Plus it was fully stealth. It apparently performed better then the f-22, in stealth, and in performance. but wasnt chosen as the primary US fighter due to some weird reason.
Which the RussianS used to build the su 57
The YF-23 did not have a forward swept wing, it's wing was triangular wing.
The YF-23 was superior in stealth, but was much less manuverable and slightly slower in super cruise.
YF-23 Did not have forward swept wings - So no, it was not something like this.
In the 1980s the X-29 was the first supersonic forward swept wing aircraft.
don't know if people realize this, but all fighters are meant to be aerodynamically unstable to some extent
Its.... Y U N K E R S !!!!! Like "Y a n k"
News Flash! With enough thrust you can make a house fly.
The germans built and flew one in 1943. Forward swept wings are more efficient for lift
name?
The German Luftwaffe built one forward swept wing aircraft toward the end of WW11 . Some of the parts on that German prototype aircraft were actually recovered from crashed American B-17 aircraft .
2:03 First and foremost, that jet pictured is the Northrop Grumman X-29, not the Sukhoi Su-47 Berkut. The Berkut, or Golden Eagle, was a twin engine jet with two tail fins, not one. And it definitely wasn't red.
i love that he did part of this in KSP
Why it should not be possible that the Us will be able to build a aircraft with forward swept wings? Thats was already a concept and maybe tested in Germany at WW2 times!
it doesnt matter anymore, there will never be dogfighting. fighters will most likely never see one another
The design of the wing shall have greater area at the base and stretch forward to cover a greater stress area. More base area is more strength of the wings.The shearing length should be more than half the wings length.Or you can change the design of the plane to have a more wider hips.
I think the future is a mach 5 lifting body with hybrid scramjet engines for suborbital passenger flights to anywhere in the world in 33 minutes.
The video failed to takl about the Grumman NAVY F-14 Tomcat that had swing swept wings and is still considered one the best Navy fighter even if it was retired.
Bro the aircraft in the thumbnail looks insane
The jet on the thumbnail was too rad for me to not watch this video
We can and by the way Russia already has. It's called the Berkut SU-47.
The thumbnail is awesome.
Both the X-29 and the Berkut were fundamentally flawed , and completely impractical . The forward-sweep had advantages , but caused enormous material-fatigue , especially at high speeds . In practice this limited the plane's top-speed , while driving the procurement and maintenance costs right through the roof . What was lacking was a means of stabilizing the wing-ends , in order to prevent twisting in the first place . The simplest way to accomplish that , is to use a dual-wing configuration . The front-set would be low-mounted and swept-back . The rear-set would be high-mounted and swept-forward . These wing pairs would be joined at their ends , NOT box or winglet joined , but actually affixed tip-to-tip . This architecture creates a triangular space-frame type geometry , with the fuselage as the base . Such is an extremely strong structure , and is capable of raising a plane's max-G to incredible levels .
*Long live space-frames !
.😎
I am Indian. I am really appreciate your work .thank you.
Where can I find an image of the swept wing aircraft shown in the thumbnail? I liked it (stealth + swept wing)
Great question. It's only outdated by 36 years.
Here's a thought, research a topic before posting a video that seems to be getting more and more common. One who's only purpose seems to be for the sake of posting anything.
SU-47 was my favorite prototype jet plane.
There is also the Tornado, the Tu-160, Tu-22...
Sweeping wings aren’t uncommon in operational military aircraft.
However forward swept wings are. The title of the video implies that it is about forward swept wings. So you were slightly off topic. Narration and footage didn’t go well together, you showed the wrong planes in more than one occasion (hell, even the wrong starfighters at the beginning).
Germany built a successful prototype late in 1944 and flew it and proved the concept. They had so many advanced designs going at the time other designs took precedence like the ME262 just to name one The germans also developed a proven twin rotor helicopter but purely experimental.
Asn a chile in Houston Texas back in 1948 I saw one of the original flying wings over Houston. It was flying out of Ellington AFB. To look in the sky
and see the bird in flight was a true shock at the time as WW II had not been over that long and we did not really know what it was. It was a Prop
powered bird and the jets came later.
THE SUKOI 47 HAS:
(1) Innovative design yes, but still minor flaws in aeronautics. More should have been pressed in design. (2) Needs to be Faster to be a true interceptor. (3) Needs to have a Better stealth architecture. (4) No where near the USA’s Radar & Weapons package suite. (5) Can they afford to and achieve mass production. This is of any new designed aircraft no matter the tech and innovation regardless of country of origin.
NOTE: A dog fight isn’t worth a hill of beans if we can see it, catch it, out run it, or shoot it down 100 miles away, or overwhelm it in numbers if close scenarios come to play. Not to mention we have plenty of battle hardened veterans which can yield an advantage via experience.
Maybe we can make another swept wing fighter that can put the wings forward and aft. Like an F-14 but more degrees of rotation.
Thunderbird 2 --- need I say more
To those who credit extraterrestrial technology, YES
Humans can design complex things and stack rocks (pyramids) WE made our greatness not Ailens!
The United States is looking into all possibilities and can't wait until their new model comes out. I'm Murican
Yes, the USA can and did; It was called the Grumman X-29.
The YB-49 did go into initial production. I think there were at least 11 planes complete or partially complete before POLITICS killed it under pressure.
is KSP now official flight modeling software? AD-1 starting @10:13
Please credit your source. That probably took a lot of work.
I would have liked to have been told WHAT advantages
a forward swept winged airplane has over traditional wings !!!...I'm over half way in and still don't know.
10:13 Hey that's Kerbal Space Program!
Nah, I’ll stay with my ME-262
Could yes, will they NO! Forward swept wings cone with A speed limit. At around Mach 1.6 you literally rip the wings off.............. Imagine that little feature on a fighter capable of Supercruise.
Would love to see your source on mach 1.6 being the maximum speed of forward swept designs. They can make the wings out of different and new materials
No. There will not be an operational fighter with reverse swept wings. The problem is (was with the X-29) that the wings twisted the wrong direction during turning thus making it more difficult to turn.
The US built one decades ago. It's almost like somebody is making a big deal our of a non-issue so that a thesis can be written. "Publish or Perish" is about 5th on the list of things that are wrong with the world.
Now building a plane with wings that can be swept forward mid-flight, that would be interesting...
Theres no wondering how anything gets in the air. The F-4 Phantom proved that if we put a big enough engine on a rock, we can get it to fly.
Also J's in german sound like Y's. So its pronounced Yunkers not "Junk-ers."
X29 is about 35 years old
Why are you talking about swept wing design when the title is forward swept wings? Forward swept winged aircraft are highly agile, bit extremely unstable platforms.
Man those engineers..
in the early part of the 40's the Germans made the Horton HO 229 almost 5 years before Northrop .Messerschmidt had a design almost identical to the xp 79 . Operation paperclip gave us a 10 year jump on where we were in 1945.
Horten H IX V1: first flight march 1944
Northrop N-9M: first flight december 1942
very good work, well done!
Acute inverse angles are very bad for radar returns. Considering that radar signature is a primary design parameter for everything we do now, any design with acute inverse angles is automatically at a disadvantage to other designs. Any benefits it brings would have to overcome that disadvantage before they could even be addressed as benefits.
If you’re gonna try to prove your theory, the least you could do is portray the actual cockpit configuration of those F-111’s! I’ve worked on three versions of that airplane and not one of their canopies opened the way that is shown in this video!
I don’t think stability is the issue. It’s structural durability which also includes cost issues since you need to use more exotic and stronger materials as well as more expensive structural designs. Lack of stealth could also be an issue but that doesn’t matter for cheaper non stealth planes……. if the cost issues with the complex structure and materials were solved.
Once again ( and as usual ) the Germans from WWII had already built and flown a swept forward jet; the Junkers Ju 287, as early as 1944. They also had a few different ones on the drawing board, Blohm & Voss 209.02, BMW Schnellbomber II, Heinkel P. 1076. As the saying oes, there is nothing new under the sun.
The material that strong and tough enough to withstand the high shear stress of the High-G, High Speed maneuver of the forward swept wing doesn't exist......
Cool. I'm an F-111 toad and a swing wing geek. I didn't know about the Mirage. Cheers.
There's no need. Thrust vectoring made forward swept wings obsolete.
Why is this even a question? The Grumman X-29 was built in 1984 and we determined it wasn't a feasible design going forward.
Feasible, yes. Practical, not really. It didn't excel in any areas besides air-to-air combat. As an experimental test bed it was remarkably successful. Best thing USAF & Nasa did since the XB-10 Valkyrie.
Stay on topic. The title of the video mentions Foward Swept wings, yet you only talk about them in the first 1/4 of the video with 0 mention of the US (even rumored to be) building a new one.
Less - no wing hypersonic glider fighter would be great ! One that could get away from SAM or shoot back to destroy it.
Been there done that successfully aready
There's a reason why forward swept wings aren't used today in jets, very unstable and also you can't achieve high speeds like modern jets today by of the resistance from the forward wings, just not practical
All they had to do was watch a bumble bee. According to scientists, they shouldn't be able to fly at all. Do they have 3 flight control computers? Having experience as a fighter bomber mechanic in the Air Force, I was a crew chief on the FB11-A (Aardvark). I did launch pilots from Pease Air Force base in New Hampshire, I remember they would fly down the east coast and be back in less than 2 hours and 30 minutes, super sonic flight had to be done over water so no sonic booms and broken windows. my favorite military aircraft was the F4-Phantom--it was to me a sports car made into an aircraft. You'll never be told what the actual top speed is as that's need to know information. You will be told what speeds it can attain but you will not be informed on the actual top speed as that information is Need to know.
@Jumpercable wireless The Phantom was and still is my favorite, I was an airframe mechanic then an airframe fitter working on different aircraft. Our Kurnass were properer war machines. Long live Spook, 69th Hammers
@@trespire I loved the way the F4-Phantom looked. It was like a person that designed Super Cars, decided to build a fighter. It had beautiful lines and I'm sure it was a fantastic handling aircraft. I was in the 509th bomb squadron (Strategic Air Command). Thank you for your service.
F4 pair used to make practice bomb runs over our radar compound in Germany in the early 1980s, at least that's what it looked like. Thought it was cool as hell when everything around would kind of rumble and shake.
As we have learned,...if your gonna build a forward swept wing.....it’s gonna be like bird when they turn real sharp,or go up and stall. It would be better! Much better! If it could then sweep back......see? Sweep wing technology works fantastic.....we just can’t do it fast enough. Picture a real falcon....that’s kinda what your shooting for. Also variable thrust has replaced the flapping? See? Mr.Northrop..Mr.Lockheed,..it’s future stuff. Probably build a small version of one. Automatic wing sweep,micro consoled....pilot...just points it! With enough thrust and a little show. It could do just about anything. Put helicopter blades in the wings....for low ground thrust and stability! Give me a lever,...I’ll move the world!
Ah, I think "Muroc AFB" is actually called Edwards AFB located (incorrectly located on your map) on Muroc dry lake bed which was named for the first settlers in the area, the Corum family.
