A wave rotor apparatus and method of using the transient gas dynamic processes within the wave rotor to accomplish an engine topping cycle. In one form of the present invention the wave rotor is a five port device. Working fluid from the highest pressure outlet port is routed to a port adjacent to and preceding an inlet port admitting air from the compressor. In a preferred form of the present invention there are two port sequences disposed along the circumference of the wave rotor apparatus.

1. A method of cooling a surface of a wave rotor comprising:providing the wave rotor having a rotatable rotor with a plurality of fluid passageways for the passage of a working fluid therethrough, the wave rotor having a plurality of outlet ports through an outlet endplate for allowing the discharge of fluid from the wave rotor and a plurality of inlet ports for allowing the entry of fluid to the wave rotor, the outlet ports including a to-turbine port and a to-purge-and-burner port and the plurality of inlet ports including a from-burner port and a purge-inlet port; rotating the rotor so as to sequentially pass the plurality of fluid passageways by the plurality of wave rotor ports; and closing the to-purge-and-burner port prior to arrival at the outlet endplate of a hot-to-cold interface between a hot working fluid entering the wave rotor through the from-burner port and a lower temperature working fluid existing within the wave rotor prior to entry of the fluid through the from-burner port; and opening the purge-inlet port to admit a purge fluid into the wave rotor while the to-purge-and-burner port is closed.
