By analyzing the advantages and disadvantages of several new types of engine, a distributed compressing vortex ramjet was introduced and its vortex stamping part was simulated.The main design process was as follows: choosing a centrifugal compressor which design flow was known, then a nozzle was designed connected to this as a vortex stamping plant; numerical simulation software was used to analyze the aerodynamic design performance. Taking the flow overlay of different numbers of compressor as a condition of entry, the effective work speed of the engine was analyzed. Finally, the engine design is feasible.
