摘要 针对嵌入式大气数据传感系统的空速校准问题,提出了一种基于释放气象探空气球获取试验空域的大气静压、静温、风速风向等大气数据,以此为基础进行空速校准的方法。通过对比动静压和真空速2种方法计算获得的马赫数结果,验证该方法的有效性。试验结果表明,该方法简单、有效,可为此类大气数据传感系统的空速校准提供参考。 Against the airspeed calibration for The Flush Airdata Sensing(FADS)system,this paper focused on a new calibration method to get the air data of static pressure,static temperature,wind speed and wind direction utilizing weather balloons.Compared two calculation results of Mach with dynamic-static pressure and true airspeed,the fight test results demonstrated this method was reasonable and effective,and can provide a reference for calibrating the flush airdata sensing system.
