Supersonic Transports - Propulsion Systems - Application of Advanced Technology

The SST will require considerable advanced technology in several areas of the engine propulsion system. The steps taken by Pratt & Whitney Aircraft to advance the state-of-the-art related to the fulfillment of these requirements are described. Above all, it is emphasized that a satisfactory commercial SST engine for all practical purposes must include a development program after engine certification and qualification that is comparable in magnitude to that achieved prior to certification. This continuing development program is essential in order to attain the maximum in engine dependability, durability, and maintenance.
