Abstract: Aimed at the shortcomings of conventional loose particle detection systems such as low efficiency and low precision, an automatic loose particle detection system for aerospace engines was developed. It was composed of swivel stand driven by motor, driver control circuit, data conditioning and acquisition circuit. With the algorithms of threshold comparison and accumulated average energy comparison, the computer gives results of particle size and location.

Key words: Aerospace engine, Loose particle, Automatic detection system
