NASA's role in aeronautics

NASA civil aviation research efforts in regard to noise reduction, development of very quiet engines, fuel conservation, and aircraft efficiency and safety are outlined. Specific projects discussed include the supercritical wing program, the fly-by-wire control system, the modified JT8D jet engine, the two-segment noise abatement landing procedure, the general aviation safety program, the GAW-1 low speed airfoil, the Army/NASA tilt rotor flight research project, and the remotely piloted research vehicle program.
