Abstract
Abstract Effectively detecting aircraft icing caused by supercooled water is essential for ensuring safe flight. This paper utilizes ultrasonic pulse-echo technology to measure ice thickness. Unlike traditional ultrasonic detection devices, which are widely used for flaw detection but are bulky, inconvenient, and have low detection accuracy, this study develops a multichannel, high-resolution pulse-echo wireless detection system with a field-programmable gate array (FPGA) as the central processing unit. The system primarily involves the design of ultrasonic pulse-echo hardware, high-speed data processing, and wireless transmission. Ice detection experiments were conducted on an ice-aluminum double-layer structure. The test results indicate that this system can effectively detect the thickness of ice layers with a resolution of 1 mm.
