| 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 de-veloped. 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 compari-son, the computer gives results of particle size and location. |
