    摘要: 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.

    摘要: A method of and system for inspecting a sealed compartment (36) within a gas turbine engine (10) is provided. The method includes using at least one acoustic transmitter (32) to produce at least one emitted acoustic signal into a compartment interior cavity (48). The acoustic transmitter (32) is in communication with the at least one port (52). The array (130) of acoustic sensors (30) is used to sense acoustic signals. The acoustic sensors (30) are disposed in proximity to the seal (50) outside of the interior cavity (48) of the sealed compartment (36). Each acoustic sensor (30) is configured to sense emitted acoustic signals produced by the acoustic transmitter (32) and to produce signal data representative of sensed acoustic signals. The presence or absence of a compromised region (54) of the seal (50) is determined using the signal data from at least one of the acoustic sensors (30) of the array (130) of acoustic sensors (30).
