Development of a technique for the detection and quantification of water and ice in the fuel tanks of an aircraft

During the daily operation, water can accumulate in the fuel tank of an aircraft. Freezing of this water during flight can result in dangerous situations during flight and on the ground. To reduce the risk of stuck mechanics or malfunctioning systems, the water is removed regularly. However, ice can be stuck in the tank if it is not removed by the normal procedures. To detect and quantify this, three different acoustic emission sensors are tested in a fuel tank model. Next to a classical piezoelectric setup, a Laser Doppler Vibrometer and an optical fibre setup are used to measure acoustic emission events during the melting of ice.
