    Abstract:

    The flush air data sensing system is a key or important flight sensor subsystem for the measurement of flight atmospheric parameters such as air pressure altitude,indicated airspeed,Mach number,Angle of attack and sideshow Angle, which are required for flight safety control,communication and navigation of flying wing pneumatic layout aircraft and precise weapon strike. The effectiveness of water-proof, dust-proof, anti-ice and de-icing design of the flush air data pressure sensor in the system is an important guarantee for accurate pressure feeling, stability of atmospheric parameters and real-time performance during flight. In this paper, aiming at the technology present status of waterproof, dustproof, anti-icing and de-icing of flush air data pressure sensors in flush air data system, analyzed the existing shortcomings and defects, combined with the needs of engineering application and research results of related engineering technology, proposed flush air data pressure sensor complex meteorological environment protection status online monitoring, heater power adaptive control and rapid disassembling design as development direction, illuminates the future of flush air data pressure sensor complex meteorological environment protection technology research goal, content, and involves water, the solutions of key technologies such as moisture monitoring technology, freezing condition monitoring technology, Surface hydrophobic and low detectable technology and easy maintenance structure design technology are given.
