旋转冲压压气机压缩转子技术分析及展望

bstract:The rotor of ramgen compressor is a new kind of system of compression that adapts the technology of shock wave compression commonly used in the supersonic flight inlet to compress air. Comparing to the conventional compressor, it has a simple configuration, and also has advantages of the higher single stage pressure ratio, small volume, higher compression efficiency and light engine weight. According to the analysis of the principle and configuration of the rotor, the key technology used in the rotor is outlined and analyzed in the paper, including the scheme of shock wave, the leakage and seal, the support of the rotor, and the boundary layer aspiration. In the end of the paper, the potential application of the rotor is discussed.
