摘要
提出一种测量飞机大气数据的新方法。将声矢量传感器应用于嵌入式大气数据传感系统上,采用矢量传感器测得声波的质点速度,通过建立质点速度、音速和空速之间的数学模型,求出飞机的马赫数,利用马赫数求出飞机的动静压。此方法计算量小,实时性好,计算仿真验证了此方法的有效性。
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 maeh number can be computed, then impact-static pressure can be solved by the roach number. The less computational load and the real-time measurement can be achieved. The simulation shows this method is effective.
