Methods used for propulsion test and evaluation for both ground and flight testing, which are very important when the engine systems under consideration are supporting hypersonic vehicles, are considered. The propulsion systems of these vehicles are highly integrated within the airframe of the vehicle with many supporting systems being shared by both. To ground test an engine system such as this, it must first be separated from the vehicle. An approach to accomplish this through the use of reference planes is discussed. Both direct connect and free jet testing methods are discussed and some of the advantages, disadvantages, challenges, and issues associated with these testing techniques and approaches as they apply to hypersonic propulsion are addressed.
