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