According to news from the China Aerodynamics Research and Development Center, the proximity sensor developed by AVIC Kaitian has undergone a total of 25 low-temperature, low-pressure, and high-humidity test environment cycles over 3 weeks and 500 hours. All meet the requirements of the experimental outline, and the frozen ice test was a complete success.
The success of this test set a record for the first time domestic aviation products passed the frozen ice test. It not only further improved the research capability of the core technology of AVIC Kaitian sensors, but also filled the gap in the domestic frozen ice test, and made positive contributions to China's aviation flight safety test.
Proximity sensors are the core products of aircraft position detection and retractable control systems, which provide the most primitive position information for the control system, so that the aircraft can retract and retract the landing gear or close the doors more safely and accurately. The proximity sensor that passed this test is the first domestic product to complete the freeze ice test according to the international airworthiness regulations of AVIC Kaitian according to the requirements of the OEM, which more effectively verifies the technical maturity of AVIC Kaitian proximity sensor And high reliability.
Over the past five years, CATIC has developed proximity sensors, relying on its own deep sensor technology, computer technology, and control technology to actively implement military-civilian integration, increase technological innovation, and break through the non-contact measurement technology of position detection. Long life, small size, light weight, wide temperature range, strong resistance to mechanical damage, easy to realize system redundancy reconstruction, easy installation and maintenance, complete system self-monitoring capability, now successfully in Jiaolong 600, MA60 , C919 and other models are widely used, greatly improving the safety and reliability of aircraft landing gear and door signal control.
