Summary	This research effort will continue to explore the development of fluidic exhaust nozzles for pulse detonation engine systems that have the ability to deliver a greatly improved nozzle thrust coefficient. This is achieved through the use of secondary air injection in the divergent portion of a converging-diverging exhaust nozzle which generates a "fluidic" nozzle wall, thus providing a capability to dynamically change the effective nozzle exit area. The secondary air required to achieve this appears to be less than 1% of the aggregate flow and can be obtained from the conventionally discarded boundary layer removal flow on supersonic intakes. Additionally, rotating detonation engines (RDE) will be studied to explore the use of RDE systems for both rocket-based and air-breathing applications.
