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 supersonic flight and to expand the speed and altitude regimes obtained with the earlier X-1 series of r...

2014年2月28日 · Two X-2 airframes, nicknamed “Starbuster,” were built at Bell’s plant in Wheatfield, New York, using stainless steel and K-monel (a copper-nickel alloy). The vehicles were designed to employ a two-chamber Curtiss-Wright XLR25 throttleable liquid-fueled rocket engine. It had a variable thrust rating from 2,500 to 15,000 pounds.

Following the success of the X-1 series, the Bell X-2 was built to extend airspeed into the Mach 3 range and to develop fight controls for supersonic aircraft. The story of the X-2, while one of amazing progress, was made tragic by loss of life and …

The Mitsubishi X-2 Shinshin (三菱 X-2 心神, formerly the ATD-X) is a Japanese experimental aircraft for testing advanced stealth fighter aircraft technologies. It is being developed by the Japanese Ministry of Defense Technical Research and Development Institute (TRDI) for …

This is the story behind a headline one test pilot made in an X plane last autumn. It was the last flight for both. At five-thirty on the morning of September 27, 1956, the alarm clock jangled harshly on the bedside table of Capt. Milburn Grant Apt, thirty-two, a senior test pilot at Edwards Air Force Base, Calif. Apt shook himself awake and ...

The rocket-powered X-2 was designed to be the first airplane capable of surpassing Mach 3 (three times the speed of sound) and to achieve altitudes above 100,000 feet. Launched from beneath the wing of a modified B-50 bomber, Capt. Milburn G. Apt flew a perfect flight profile and successfully achieved a speed of Mach 3.2 (2,094 mph).

2019年3月26日 · This plane was the first to reach Mach 3, but it had to make real sacrifices on the altar of speed. Was it worth it? The successor to Chuck Yeager's X-1 paid a deadly price for breaking this supersonic record.

Re-live 1950's Edwards AFB with William Holden, Lloyd Nolan and the X-2 in this Hollywood film.

2023年5月1日 · The Bell X-2 was a swept-wing, rocket-powered research aircraft designed to fly three times faster than the speed of sound. It was flown to investigate the problems of aerodynamic heating, stability, and control effectiveness at high speeds and altitudes. On each mission, a Boeing B-50 bomber carried the X-2 to launch altitude and released it.

Bell aircraft built two X-2 aircraft. These were constructed of K-monel (a copper and nickel alloy) for the fuselage and stainless steel for the swept wings and control surfaces. The aircraft had ejectable nose capsules instead of ejection seats because the development of ejection seats had not reached maturity at the time the X-2 was conceived.
