The NASA Advanced Transport Technology Program.

Review of an advanced technology program initiated by NASA to expedite the development and application of advanced technologies to the next generation of subsonic CTOL jet transports. The major technical elements of this program include airframe and engine system studies for identifying technology needs, technology development for providing the necessary base in those areas of the aeronautical disciplines offering significant payoffs, and exploratory flight vehicles for validating advanced concepts and demonstrating specific benefits associated with civil applications. The possible benefits and application of the NASA-developed supercritical aerodynamic technology are discussed in some detail. Early experimental aerodynamic results obtained from wind tunnel and flight investigations are included.
