  2. Drop test - Wikipedia

    en.wikipedia.org/wiki/Drop_test

    A drop test is a method of testing the in-flight characteristics of prototype or experimental aircraft and spacecraft by raising the test vehicle to a specific altitude and then releasing it. Test flights involving powered aircraft, particularly rocket-powered aircraft, may be referred to as drop launches due to the launch of the aircraft's ...

    en.wikipedia.org/wiki/NASA_X-38

    The X-38 is an experimental re-entry vehicle designed by NASA to research a possible emergency crew return vehicle (CRV) for the International Space Station (ISS). The 1995–2002 program also developed concepts for a crew return vehicle design that could be modified for other uses, such as a possible joint U.S. and international human spacecraft that could be launched on the French Ariane 5 ...

    The first X-40A drop test occurred at Holloman AFB, New Mexico on August 11, 1998 at 06:59. It was released from an altitude of approximately 10,000 feet (3,000 m) [2] and 2.5 miles (4.0 km) away from the end of Runway 04 by a UH-60 Black Hawk helicopter [1] (later tests used an Army CH-47D Chinook helicopter).

    An X-37 first flew during a drop test in 2006; its first orbital mission was launched in April 2010 on an Atlas V rocket, and returned to Earth in December 2010. Subsequent flights gradually extended the mission duration, reaching 780 days in orbit for the fifth mission, the first to launch on a Falcon 9 rocket.

    It was not chosen to make the test drop at Bikini Atoll and left Kwajalein on 1 July, the date of the test, reaching Fairfield-Suisun Army Air Field, California, the next day. [37] The decision was made to preserve the Enola Gay, and on 24 July 1946, the aircraft was flown to Davis–Monthan Air Force Base, Tucson, Arizona, in preparation for ...

    en.wikipedia.org/wiki/Bell_X-2

    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 ...

    en.wikipedia.org/wiki/NASA_X-43

    The X-43A aircraft was a small unpiloted test vehicle measuring just over 3.7 m (12 ft) in length. [4] The vehicle was a lifting body design, where the body of the aircraft provides a significant amount of lift for flight, rather than relying on wings. The aircraft weighed roughly 1,400 kg (3,000 lb).
