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 ...
The Bell Aircraft Corporation was an American aircraft manufacturer, a builder of several types of fighter aircraft for World War II but most famous for the Bell X-1, the first supersonic aircraft, and for the development and production of many important civilian and military helicopters.
The Bell X-1 was the first crewed airplane to exceed the speed of sound in level flight and was the first of the X-planes. XS-1 pilots. Pilot Agency Flights
The XB-1 supersonic flight took off near Edwards Air Force Base in Mojave, California, and flew through the Bell X-1 Supersonic Corridor and the Black Mountain Supersonic Corridor for 35 minutes.
The XLR11-RM-5 engine was first used in the Bell X-1.On October 14, 1947, the X-1 became the first aircraft to fly faster than the speed of sound (Mach 1). The XLR11-RM-5 was also used in the X-1A and X-1B, and as a booster engine in the U.S. Navy's D-558-2 Douglas Skyrocket turbojet (where it was designated the XLR8-RM-5).
Additionally, the X-22 was to provide more insight into the tactical application of vertical takeoff troop transporters such as the preceding Hiller X-18 and the X-22's successor, the Bell XV-15. Another program requirement was a true airspeed in level flight of at least 525 km/h (326 mph; 283 knots).
In 1947, Chuck Yeager became the first human to break the sound barrier when he pushed the Bell X-1 past Mach 1 during a flight over the Mojave Desert. Boom Supersonic XB-1 breaks sound barrier ...
The Bell X-2 (nicknamed "Starbuster" [1]) was an X-plane research aircraft built to investigate flight characteristics in the Mach 2–3 range. The X-2 was a rocket-powered, swept-wing research aircraft developed jointly in 1945 by Bell Aircraft Corporation, the United States Army Air Forces and the National Advisory Committee for Aeronautics (NACA) to explore aerodynamic problems of ...
