As part of NASA's High-Speed Research Program, NASA's Ames Research Center (ARC) was using its National Full-Scale Aerodynamics Complex to study and curb the noise from the takeoff exhaust or "plume" of turbulent air in the wake of future supersonic jetliners without affecting take-off performance. Project Manager Paul Soderman, an aeronautical and acoustical engineer, said that such future aircraft would have to comply with Federal Aviation Administration (FAA) regulations. An exhaust nozzle of an "ejector suppressor" type was being studied by laser and infrared video. (NASA Release, Jan 31/94)
NASA reportedly transferred $990,000 to the Defense Department's Ballistic Missile Defense Organization to maintain the Delta Clipper program. McDonnell Douglas Aerospace had developed a rocket that takes off and lands vertically, which is covered by this program. NASA wished to keep the option of using the DC-X as a flight demonstrator of single-stage-to-orbit technologies in support of NASA's advanced launch technology effort. The program was operated from the White Sands Missile Range in New Mexico. (RTW, Jan 31/94; H Post, Feb 3/94)
