abstract

A method for aerothermodynamic preliminary design of a wave engine is presented. The engine has a centrifugal precompressor for the wave rotor which feeds high and low pressure turbines. Three specific wave engine designs are presented. Wave rotor blades are naturally cooled by the ingested air; thus combustion temperatures can be as high as 1900°K. Engine pressure ratios of over 25 are obtained in compact designs. It is shown that no nozzles at the end of the rotor blade passages yield the highest cycle efficiencies which can be over 50%. Rotor blades are straight and easily milled, cast or fabricated.
