The accurate measurement of air data is critical for the navigation and flight control of vehicles. Comparing with the intrusive conventional air data measurement system, the flush air data sensing system is more suitable to hypersonic vehicles, stealth vehicles and high angle of attacks vehicles. The development of the flush air data sensing system is reviewed. The components of the flush air data sensing system are introduced. Four key technologies during the application of this system(pressure ports arrangements, aerodynamic models and solution algorithms, calibration algorithms, the failure detection and management) are proposed. Based on the different application schemes on different vehicles abroad, different application modes of these four key technologies are analyzed. These four key technologies are tightly related to the accuracy and reliability of the system. Finally, the applications of the flush air data sensing system to future aeronautical/astronautical vehicles are prospected.
