An aircraft includes a turbine engine, a vibration sensor, and a processor. The vibration sensor is attached to the turbine engine and is configured to output a vibration sensor signal. The processor is programmed to determine whether the vibration sensor signal indicates that fan case liner damage has occurred due to icing conditions. The processor is further programmed to indicate that a fan case inspection should be conducted in response to the vibration sensor signal indicating that fan case liner damage has occurred.

Detection of fan case liner damage during turbine engine operation

The pilot communication system employs a transducer array of individual spaced apart speakers and/or microphones for deployment within the cockpit. A signal processing circuit interfaces with the transducer array and also with the aircraft avionics communication system, and selectively applies different time delays to the individual speakers and/or microphones to create in the array an acoustic beam having steerable coverage within the acoustic space of the cockpit. By adjusting the time delays the signal processing circuit directs and focuses sound from the speakers to the pilot and similarly focuses the microphones on the pilot's mouth. In this way the pilots can communicate with each other and with air traffic control without the need to wear headsets. The system also significantly reduces flight deck warnings from being introduced into the cabin environment.

Phased array speaker and microphone system for cockpit communication

A system is provided for identifying a source of an audible nuisance in a vehicle. The system includes a device configured to receive a visual dataset, and to generate a camera signal in response thereto. The system includes a dock configured to removably couple to the device. The dock includes a microphone array configured to receive the audible nuisance, and to generate a microphone signal in response thereto. The system includes a processor module configured to be communicatively coupled with the device and the dock. The processor module is configured to generate a raw soundmap signal in response to the microphone signal. The processor module is configured to combine the camera signal and the raw soundmap signal, and to generate a camera/soundmap overlay signal in response to combining the camera signal and the raw soundmap signal.
