LIDAR BASED FOD DETECTION FOR GAS-TURBINE ENGINES

A foreign object debris (FOD) detection system (265; 465; 565) for a gas turbine engine (120) comprises a light detection and ranging (LiDAR) sensor assembly (270; 670; 770; 870). The LiDAR sensor assembly is configured to scan a pre-determined volume (320; 415; 515) within an inlet (310; 410; 510)...

Beschreibung
Zusammenfassung:	A foreign object debris (FOD) detection system (265; 465; 565) for a gas turbine engine (120) comprises a light detection and ranging (LiDAR) sensor assembly (270; 670; 770; 870). The LiDAR sensor assembly is configured to scan a pre-determined volume (320; 415; 515) within an inlet (310; 410; 510) of the gas turbine engine. The inlet may be defined by a nacelle (101) of the gas turbine engine. The LiDAR sensor assembly may comprise a single transceiver, a transmitter and a receiver, a plurality of transmitters (772) and a receiver (780), or a plurality of receivers (880) and a transmitter (872).
