China Academy of Aerospace Aerodynamics has tested an embedded air data sensing (EADS) system on an advanced research vehicle at subsonic speeds during a series of successful flights. For these tests, the EADS system was calibrated between Mach 0.20 and Mach 0.90, and flight test data was collected between Mach 0.10 and Mach 0.90, α = − 4° ~ 12°, β = − 4° ~ 4°. The EADS system received pressure data from surface pressure ports and generated a real-time angle of attack, angle of sideslip, real airspeed, Mach number, free stream pressure and dynamic pressure estimation on board the vehicle. The solution data were primarily used to evaluate the EADS system performance, and the estimated flight parameters was used by the flight control algorithms on the vehicle for these successful flights. This paper provides an overall architecture of the EADS system and solution algorithms and presents the flight solution algorithm performance. This paper also provides comparisons results of the wind tunnel results and theory analysis. Results indicate that the EADS system can be used adequately to estimate the flight parameters of the vehicle during the flights. The system performance has been evaluated by comparing the real time EADS to the other on board system air data computer measurements to give a quantitative comparison. Factually agreements of approximately 3 m/s in real air speed and 0.5° in angle of attack and angle of sideslip have been achieved. This is the first successful application of the EADS system to the real-time flight control in subsonic vehicle in our country.
