Abstract A new measuring airdata algorithm is put forward.A vector sensor is applied to the flush airdata sensing(FADS) system to measure the airdata, the mathematics model of particle velocity, sound velocity and airspeed is established, the mach number can be computed, then impact-static pressure can be solved by the mach number. The less computational load and the real-time measurement can be achieved. The simulation shows this method is effective.
