A wide variety of Advanced Short Takeoff and Vertical Landing (aircraft) (ASTOVL) propulsion concepts were studied against a number of different customer requirements including NST6464. These studies are reviewed with particular reference to those aspects which affect concept choice and the quality of the overall system. Once these studies were complete, a reexamination of the principal attributes of a STOVL aircraft was carried out by visiting Harrier operations on deployment both on land and at sea. This together with the results of the full scale landing simulations of an ASTOVL aircraft led to the evolution of a propulsion system for supersonic STOVL aircraft. The key elements of this propulsion system are that in the STOVL regime the propulsion system is unmixed and has the characteristics of the Pegasus (i.e., cool front jets and full nozzle vectoring) but is a mixed flow afterburning turbofan in the flight regime. The critical technologies for this propulsion system are identified and the programs required to underwrite them are outlined. The major characteristics of this propulsion system are compared with other systems and those elements which contribute to a low risk propulsion system are identified.
