Did Jack Northrop see the B 2?
Jack Northrop, the aviation pioneer who founded Northrop Corp., was granted an extraordinary government security clearance just before his death in 1981 to see the company’s design for the B-2 Stealth bomber, which resurrects the “flying wing” concept he had invented in the 1940s, the company’s chairman disclosed …
What happened to the YB 49?
The last operational YB-49 prototype was destroyed on 15 March 1950, during high-speed taxi trials at Muroc Field. The nose wheel began to encounter severe vibration problems and finally collapsed; the aircraft was completely destroyed in the ensuing fire.
Who had the first flying wing?
The first powered all-wing aircraft to fly was the D. 4 in Britain in 1908. It was a V-shaped biplane, built by a British army officer, John William Dunne, who acknowledged that it was “more a hopper than a flyer.”
When was the first flying wing developed?
1909
Possibly the first true flying wing, which was shaped like an elliptical seed, was designed and flown by Czechoslovakian designer Igo Etrich in 1909.

Designed and manufactured by Northrop, later Northrop Grumman, the cost of each aircraft averaged US$737 million (in 1997 dollars).
Are Flying Wings stable?
The results obtained show that the flying wing configuration can be dynamically stable; however, the longitudinal and lateral- directional oscillations decay so slowly that a stability augmentation system would be required to assure an acceptable dynamic response of the aircraft.
Who invented the Delta Wing?
Alexander Lippisch
The practical delta wing was pioneered by the German aeronautical designer Alexander Lippisch in the years following the First World War, using a thick cantilever wing without any tail.
Why are flying wings unstable?
The moving CP means that the wing is inherently unstable. This is because it equally opposes the forces made by the unstable wing. Why Flying Wings Don’t Have Stabilizers. Flying wings need a considerable distance between the CP and CG, a lot more so than normal wings on a tradition aircraft with a tail.
Why are flying wings swept?
In transonic flight, a swept wing allows a higher Critical Mach Number than a straight wing of similar Chord and Camber. This results in the principal advantage of wing sweep which is to delay the onset of wave drag. A swept wing is optimised for high speed flight.
Why did Grumman leaving Long Island?
Grumman insists that it will remain in Bethpage. Grumman is a case study of the massive restructuring taking place within the United States defense industry and the need to shift manufacturing away from high-cost, high-tax states such as New York, Mr. Harwood says.
Why did Northrop choose the YB-49 flying wing?
Northrop adopted the flying wing shape for the B-2 because it offers the advantage of a low radar cross-section. Advances in fly-by-wire technology have made the B-2 much easier to fly than the YB-49 (or the YB-35).
Is the YB-49 the same as the B-36?
However, the fuel-hungry engines shrank the YB-49s combat radius, making it more comparable to a medium bomber than to the long-range B-36. Unfortunately, while the YB-49 could outrun the B-36, it lacked the speed of Boeing’s new B-47 Stratojet medium bomber. Sabotage? The YB-49 prototypes suffered an unusual run of bad luck.
What was the service ceiling of the YB-49?
The service ceiling of the YB-49 also increased, an important consideration for escaping Soviet interceptors. However, the fuel-hungry engines shrank the YB-49s combat radius, making it more comparable to a medium bomber than to the long-range B-36.
Is the B-2 Spirit the same as the B2?
The B-2 Spirit, while utilizing radically different technology, bears a strong visual resemblance to its distant cousin. Indeed, the two aircraft share exactly the same wingspan. Northrop adopted the flying wing shape for the B-2 because it offers the advantage of a low radar cross-section.
