| Abstract: |
| A new aerodynamic design principle has been put forward to solve the inner flow problems of the supersonic or transonic compressors with large deflection which can further increase the stage load. This principle is called as low-reaction and aspirated aerodynamic design principle for supersonic or transonic compressor. A verification of the principle has been carried out. The three-dimensional viscous numerical simulation results show that a stage pressure ratio 2.5with efficiency 87% at tip tangential speed 370m/s has been attained, which demonstrates the possibility of this principle to increase the stage load. |
