由可移动插板式畸变发生器产生进气总压畸变流场 ,以综合畸变指数评定流场畸变程度 ,试验研究了进气总压畸变对某型涡喷发动机气动稳定性的影响。试验确定了发动机的最大 (或临界 )综合畸变指数和总压畸变敏感系数。
The total inlet pressure distortion flow field was generated by the movable flapper distortion generator. The distortion degree of the flow field was evaluated by comprehensive distortion index. The effect of total pressure distortion on the aerodynamic stability of a turbojet engine was experimentally studied. Test to determine the engine’s maximum (or critical) integrated distortion index and total pressure distortion sensitivity coefficient.
