Bell X-1-2. The X-planes are a series of experimental United States aircraft and rockets, used to test and evaluate new technologies and aerodynamic concepts. They have an X designator within the US system of aircraft designations, which denotes the experimental research mission.

The Northrop X-4 Bantam is a prototype small twinjet aircraft manufactured by Northrop Corporation in 1948. It had no horizontal tail surfaces, depending instead on combined elevator and aileron control surfaces (called elevons ) for control in pitch and roll attitudes, almost exactly in the manner of the similar-format, rocket-powered ...

2024年1月22日 · Unlike her avian namesake, the X-4 Bantam could fly high, far, and fast. She actually drew her inspiration from a former WWII nemesis, namely Nazi Germany’s Messerschmitt Me 163 Komet, which was...

The first X-4 was grounded after only 10 flights, and only the second X-4 (on display at the museum) was used in the joint USAF/NACA program. Instability of the X-4 at high speed led to the conclusion that semi-tailless aircraft were not suitable for …

2014年2月28日 · The X-4 was designed to test a semi-tailless wing configuration at transonic speeds. Many engineers believed in the 1940s that the such a design, without horizontal stabilizers, would avoid the interaction of shock waves between the wing and stabilizers.

The Bell X-1 (Bell Model 44) is a rocket engine–powered aircraft, designated originally as the XS-1, and was a joint National Advisory Committee for Aeronautics–U.S. Army Air Forces–U.S. Air Force supersonic research project built by Bell Aircraft. Conceived during 1944 and designed and built in 1945, it achieved a speed of nearly 1,000 ...

2006年9月13日 · The X-4 was a small twinjet-engine airplane that had no horizontal tail surfaces, depending instead on combined elevator and aileron control surfaces (called elevons) for control in pitch and roll attitudes.

The X-4 was initially powered by two Westinghouse XJ30 turbojet engines and then by J30 turbojet engines with 1,600 pounds of thrust each. These engines boosted the X-4 up to speeds of 630 mph and up to altitudes of 43,300 feet.
