The results indicate that:(1) for high subsonic inlet flow,the boundary layer in blade suction surface being aspirated can increase the cascade pressure rate and flow turning angle,but not always reduce flow loss;(2) for middle subsonic inlet flow,the boundary layer in blade suction surface being aspirated can increase the cascade pres.
结果表明:(1)对于高亚声速压气机叶栅,采用吸力面附面层吸除可提高叶栅的扩压度,但不一定能减小流动损失。
It is emphasized that the kind of extremely low altitude, subsonic winged missiles should play a key role in the future, and some supersonic and combined winged missiles should be developed actively and gradually so as to b.
