Radial C-shaped diffusion structure suitable for supersonic incoming flow

The invention belongs to the technical field of power machinery, and discloses a radial C-shaped diffusion structure suitable for supersonic incoming flow, which comprises radial diffuser blades (3), a C-shaped groove (4) is formed in the front edge of the radial diffuser blade (3), the radial diffuser blade (3) is arranged on the outer side of the centrifugal impeller (5), the centrifugal impeller (5) can rotate between the air inlet casing (6) and the base disc (7), and working fluid flows through the radial diffuser blade (3) from the centrifugal impeller (5) and enters the axial serial blade (16) and the exhaust shell (1). And the radial diffuser blades (3) are positioned between the base disc (7) and the wall surface of the diffuser casing (2). The size of a flow separation area can be reduced, the uniformity of outlet airflow is improved, the efficiency of the gas compressor is improved, and the possibility of surge or stall is reduced. 本发明属于动力机械技术领域，公开了一种适用于超音速来流的径向C型扩压结构，包括径向扩压器叶片(3)；所述径向扩压器叶片(3)的前缘处设
