摘要

A rotary ramjet engine (E) is provided operating with a very low axial flow component. The engine has a rotor (210), shaft (204), a plurality of ramjet combustors mounted on the periphery of the rotor (210). A set of spaced helical strakes extend from the outside surface of the rotor toward the interior wall of the engine case, less a running clearance therefrom. A centerbody (36) is provided for each ramjet engine. The centerbody is disposed parallelto the strakes and includes leading edge structure (34), opposing sidewalls, a shaped cavity, and a rear end wall.
