“…Aircraft icing detection is an important technical means to achieve flight icing warning and ensure flight safety [6,7]. At present, there are various methods for detecting aircraft icing, such as magnetostriction ice detectors [8], infrared ice detectors [9,10], optical fiber ice detectors [11], impedance ice detectors [12,13], ultrasonic ice detectors [14,15], and other sensors. Each type of sensor has its detection advantages and disadvantages, but currently, the icing sensors used on aircraft can only determine whether ice is forming and cannot provide more ice information.…”

In-flight icing detectors are important for the flight safety of aircraft. Detectors based on ultrasonic pulse-echo can be used for detecting ice thickness. To study the influencing factors of ultrasonic pulse-echo detection performance, a simulation model of elastic wave-piezoelectric coupling was established, which was used to analyze the influence of different types of piezoelectric ceramics, matching layers with different acoustic impedances, and different substrate materials on ultrasonic pulse-echo signals. It was found that when aluminum is used as the substrate material, the ultrasonic echo signal has a higher signal-to-noise ratio. Furthermore, the influence of aluminum substrate materials with different thicknesses on ultrasonic pulse-echo was analyzed. The ice thickness can be identified by measuring the time of flight between the aluminum-ice interface echo and the ice-air interface echo. The results indicate that when the thickness of the aluminum substrate is 25mm, the upper detection limit of ice layer thickness can reach about 10mm. Therefore, the detection upper limit of ice layer thickness can be extended by appropriately increasing the thickness of the aluminum substrate material.
