ECN-2353 Il wingless, corpo di sollevamento aereo seduto su Rogers Dry Lake a ciò che è ora di NASA Dryden Flight Research Center, Edwards, California, da sinistra a destra sono l'X-24A, M2-F3 e l'HL-10. Il corpo di sollevamento aereo ha studiato la fattibilità di manovra e l'atterraggio di un artigianato aerodinamiche progettate per il rientro dallo spazio. Questi organi di sollevamento di aria sono stati lanciati da un B-52 nave madre, poi volò powered by i propri motori a razzo prima di effettuare un approccio distaccato e lo sbarco. Essi hanno contribuito a convalidare il concetto che una navetta spaziale potrebbe rendere gli sbarchi accurate senza alimentazione. L'X-24A fle

ECN-2353 The wingless, lifting body aircraft sitting on Rogers Dry Lake at what is now NASA's Dryden Flight Research Center, Edwards, California, from left to right are the X-24A, M2-F3 and the HL-10. The lifting body aircraft studied the feasibility of maneuvering and landing an aerodynamic craft designed for reentry from space. These lifting bodies were air launched by a B-52 mother ship, then flew powered by their own rocket engines before making an unpowered approach and landing. They helped validate the concept that a space shuttle could make accurate landings without power. The X-24A flew from April 17, 1969 to June 4, 1971. The M2-F3 flew from June 2, 1970 until December 20, 1972. The HL-10 flew from December 22, 1966 until July 17, 1970, and logged the highest and fastest records in the lifting body program. The X-24 was one of a group of lifting bodies flown by the NASA Flight Research Center (FRC--now Dryden Flight Research Center), Edwards, California, in a joint program with the U.S. Air Force at Edwards Air Force Base from 1963 to 1975. The lifting bodies were used to demonstrate the ability of pilots to maneuver and safely land wingless vehicles designed to fly back to Earth from space and be landed like an airplane at a predetermined site. Lifting bodies' aerodynamic lift, essential to flight in the atmosphere, was obtained from their shape. The addition of fins and control surfaces allowed the pilots to stabilize and control the vehicles and regulate their flight paths. Built by Martin Aircraft Company, Maryland, for the U.S. Air Force, the X-24A was a bulbous vehicle shaped like a teardrop with three vertical fins at the rear for directional control. It weighed 6, 270 pounds, was 24.5 feet long and 11.5 feet wide (measuring just the fuselage, not the distance between the tips of the outboard fins). Its first unpowered glide flight was on April 17, 1969, with Air Force Maj. Jerauld Gentry at the controls. Gentry also piloted its first powered flight o
