China's proximity sensor ice test

Recently, it was reported from the China Aerodynamics Research and Development Center that the proximity sensor developed by AVIC Kaitian has undergone 25 cycles of low-temperature, low-pressure, and high-humidity testing over more than 500 hours in three weeks. The test data are in line with the requirements of the experimental program, and the freezing ice test is a complete success.

The success of this test set a record for the first time that domestic aviation products passed the freeze test. It not only further improved the core technology research capability of AVIC Kaitian Sensors, but also filled the gap in domestic ice-free testing and made positive contributions to China's aviation flight safety test.

The proximity sensor serves as the core product of the aircraft position detection and retraction control system, providing the control system with the most original position information, so that the aircraft can safely and accurately retract the landing gear or close the door. The proximity sensor that passed the test was the product that AVIC Kaitian had completed the freeze test in accordance with international airworthiness requirements according to the requirement of the main engine plant, which more effectively validated the technological maturity of the AVIC Kaitian proximity sensor. And high reliability.

AVIC Kaitian developed proximity sensors for five years. Relying on its own deep sensor technology, computer technology, and control technology, it actively implemented military-civilian integration, increased technological innovation, and broke through the non-contact measurement technology of position detection. The product is more traditional than the terminal switch. Long life, small size, light weight, wide range of temperature resistance, strong resistance to mechanical damage, easy to implement system redundancy reconstruction, easy installation and maintenance, complete system self-monitoring capability, has now succeeded in Xiaolong 600, MA60 Many models such as the C919 have been widely used, greatly improving the safety and reliability of aircraft landing gear and door signal control.
