X-33 Hypersonic Aerodynamic Characteristics [PDF]
Journal of Spacecraft and Rockets, 1999 Lockheed Martin Skunk works, under a cooperative agreement with NASA, will build and fly the X-33, a half-scale prototype of a rocket-based, single-stage-to-orbit (SSTO), reusable launch vehicle (RLV). A 0.007-scale model of the X-33 604B0002G configuration was tested in four hypersonic facilities at the NASA Langley Research Center to examine vehicle ...
