| Abstract: | Three kinds of the simulation equipment had been investigated for different M numbers on the same testing vehicle. Conventionally the total pressure distortion is used. But according to the theory of compressor, the velocity distortion may be more essential. So not only the total pressure distortion patterns but also the velocity distortion patterns had been measured. The relationship between the velocity distortion and the total pressure distortion had been found. The configuration of the velocity vector means that the attack angle of the blade of compressor will be fluctuated both by the distribution of the velocity and by the direction of it. According to the outlet distortion pattern of the aircraft intake and on the basis of the characteristics of baseline simulator, a reasonable composite equipment can be achieved. The model must be tested and revised. |
