I have flown several gliders that had mildly swept forward wings. That was done for a very practical reason, as those gliders were all 2 seat trainers, and the rear seat was at the CG position of the lift of the wings. That made the weight of the person in that seat, non-contributory to the trim of the glider (only affected the total weight), and the front pilot was the only one that affected the weight and balance.

You want us to buy into your channel? 1:50 in and you state that WWII aircraft wings were of the straight design, you named a few including the Spitfire. The spitfire wing is elliptical. It doesn't quite fit in the ME-109 or P-51. Yes the main spar is perpendicular to fuselage center-line but the plan is a drag reducing ellipse.

Question for the engineers out there: During the design of the forward swept wing, did the engineers already know about the need for the twist stiffness (Kt in the diagram@8:02), or did they have to discover it through observation and/or analyzing crash data and failed wings? Not having an engineering education, I'm not sure if or how they could have even know it was an issue.

The canard positive lift vs. horizontal stabilizer negative lift is far from new. Stability in a design is determined by the degree the aircraft will tend to return to normal flight. The canard was used by the highly-efficient Wright Flyer. The problem was stability. Canards are destabilizing like putting feathers on the front of the arrow. Forward swept wings have the same effect plus adds instability to the yaw axis which is where the twist problem comes from. The swept forward wing moves the center of lift closer to the canard, which makes it short-coupled, which makes it highly responsive, like a car with a short wheelbase. Being short-coupled also gives little leverage to stop things once they start to get out of hand without adding a lot of strength and surface area which is self-defeating. The B1 Lancer has a small computer controlled canard to assist with this problem, and the B2 depends entirely on the computer for its stability. The Germany talk I always hear is laughable. In 1939 Germany was the only country who wanted war and the only one who had prepared for one. They had destroyed everyone else's country in the previous war. That facts are, Germany lost technologically to both the US and Great Britain in every technology that mattered to the war. The US The Lockheed L-133 was a practical canard jet proposed in 1939 with axial flow engine that they would be prevented from building. The Vought V-173 "Flying Pancake" flew in 1942. Jack Northrop made the flying wing the focus of his work during the 1930s. In 1941 before the USA entered World War II, Northrop and Consolidated Vultee Corporation had been commissioned to develop a large wing-only, long-range bomber designated XB-35. He was crushed when they went with the B-36 but before he died while confined to a wheel chair and unable to speak, the Air Force briefed him on their new, highly classified, Northrop-built B-2 Spirit bomber. Built in a flying wing configuration and incorporating many of Jack Northrop’s design innovations, the B-2 has evolved into the most capable bomber in aviation history. Upon seeing the drawings and a scale model of the aircraft, Northrop reportedly wrote on a sheet of paper in a shaky, feeble hand, "Now I know why God has kept me alive for 25 years." When WW II was going a year past projected, they told Lockheed they might need a jet fighter to counteract Germany's jets against their bombers, but in order to make sense, they had to have it in 5 months. They delivered a debugged and flying P-80 in and a production plan in 137 days. It saw limited service due to Germany's mismanagement and more sudden collapse. Notice it's the Goddard Space Flight Center. Robert Goddard, whose plans Germany extended for their own rocket program, was also denied pursuing rockets like Germany in WW II. All the US would pay for was rocket assisted take-off for the war effort. The German rocket program had no strategic value and a complete waste of resources. The best Germany achieved was 7 miles from the aiming point, down from 28 miles, and they killed more of their own people building it than all of the rockets killed. By contrast, the US spent 1/10th the resources on the atomic bombs and it saved 1/2 a million US casualties, shortened the war, and saved the enemy from starvation. Great Britain defeated them with their radar by 1940, and drove them off the sea with their electronics, hedge hogs, and Ultra. By 1941 Great Britain already had them mired in North Africa. They were stuck in Stalingrad by 1942, waiting for a tank that was not ready. They spent 2 years, massive resources to build an Atlantic Wall that was overcome in less than 8 hours with far fewer casualties than they took to build it. The deployment of technology that had no strategic value for the war was to deceive themselves as to their situation. Obviously the allies would target those involved in these technologies after the war because they focused on winning and did not invest in technologies that did not align with that goal during the war.

You are also correct on how the US won the technology race, as well as the britains. And yeah, the Russia move was probably the biggest strategic blunder ever made by a warring force next to the Pearl Harbor attacks and Napoleon's shot at Russia. However, many... Deja vu. Hmm. However, many technologies discovered post war were grounded in wartime research, not unoften by german researchers. The main reason many things weren't implemented or realized was due to the fact that Germany was fighting almost a five front war; eastwards russia westwards the US, northwards Britain, southwards.... ehm... France, I guess? Kind of. Hey, normandy. Anyways, they also had resources invested in africa. The thought process behind attacking russia was probably to preemptively stop them from mobilizing a force capable of overrunning germany. What I mean to say is, without overreaching and thus minimizing ressources and putting priority into maintaining a set standard Germany's technology could most definitely have rivaled it's opponents. However it would have resulted in Russia being an even more powerful opponent. Either way, the one who starts the war without the means to end it always loses. Most definitely if your allies are not on par with your enemy's allies. In a way, I'm glad Germany lost, though. Then again, a shame to all the history that was destroyed in the process.

very intersting. the stabilization shouldnt be a problem anymore today, as it is common practice in drones now. maybe it would be interesting to pick this design back up.

Pretty well done, however, you forgot to mention/glossed over the fact that conventional wing designs include a twist from root to tipi so that the ailerons are at a lower angle of attack and remain effective early in the stall to help prevent the aircraft from rolling over and entering a spin.

Hace 4 días
wataaaaaaaa
wataaaaaaaa

But that very early part of the stall, when an aileron goes down, it will increase the angle of attack and cause that wing to fully stall before the other wing;Hence the neutral aileron instruction for recovery on many airplanes.

I think this plane was a gift to the Soviet Union. You have to understand the times. When this thing was brought out, the US was quietly ruining the USSR by making them blow large chunks of their R&D budget on insane projects. I mean, sure this was a model for an incredible dog fighter. Unbelievably maneuverable, etc. We had a lot of stuff like this in the can and we were letting the reds try to copy some of it, knowing that they were racing down a dead end alley. Why would we need this, when an F-14 can turn inside a Cessna 150 (watched one do it at Luke AFB in 1980 - absolutely shocking!) and an F-16 can do better than that? (And now, an F22 can tie them all in knots!)
