Zusammenfassung:An inspection system (88) for rotating fan rotor blades (58) in a gas turbine engine (20) is provided. The system includes a plurality of cameras (100) and lids (108), and a cleaning system (94). The cameras (100) are each controllable to capture an image of a leading edge (62) of a fan rotor blade (58) and produce signals representative thereof. Each camera (100) is mounted to a static structure (54, 74) disposed forward of the fan rotor blade stage (52). The lids (108) are attached to the static structure and are selectively movable between closed and open positions. In the closed position at least one camera (100) is enclosed. In the open position the camera (100) is at least partially exposed and has a field of view of the rotating fan rotor blades (58). The cleaning system (94) is controllable to selectively produce a body of fluid relative to the at least one camera (100) when the respective lid (108) is in the open position.
