Abstract: Based on the mechanicsm of inlet swirl, the measures to prevent andrestrain the inlet swirl of present aircraft in an all-round way from the inlet designpoint of view are studied’ It is hoped that the author’s thinking will benefit the solution of the problems in engine/inlet compatibility arising from swirl’
