Abstract : The Hybrid Propulsion for Air Force Applications Study was performed by the Air Force Phillips Laboratory at Edwards Air Force Base, California. The hybrid propulsion study's four main objectives were (1) to conduct a survey of the current state-of-the-art technology in hybrid propulsion, (2) to determine if there is a payoff for using hybrid propulsion in Air Force missions, (3) to make recommendations as to whether or not hybrid pro- pulsion should be pursued by Phillips laboratory, and (4) if hybrid propulsion is to be pursued, produce a technology development plan. An industry survey of current state-of-the-art technology in hybrid propulsion identified several advantages and disadvantages associated with hybrid propulsion. Identified areas of concern were combustion efficiency, fuel regression rate, and mixture ratio shifts. The identified Air Force application was the use of a hybrid propulsion system in an air-to-air missile. Volume-limited designs were produced that showed that hybrid propulsion offers good potential for an air-to-air missile that can meet insensitive munitions requirements as well as provide improved energy management. A flight engagement analysis was performed to establish the mission advantage supplied by the hybrid systems formulated in the design task.
