Design of high-precision air data solving system for advanced vehicles
针对先进高性能飞行器对高精度大气数据的测控需求,研发设计了一套适用于亚声速飞行器的嵌入式大气数据传感(flush air data sensing,FADS)系统.该系统首先基于数值建模技术建立了FADS系统模型的压力数据库,并针对建模数据精度及风洞试验校准数据分析了Ma=0.2～0.4 对应的压力误差限;其次,开发了攻角实时解算算法,并集成到工程原理样机中;最后基于风洞试验和飞行试验对FADS系统的实时解算算法及样机进行了系统评估,并通过事后模…查看全部>>
In this paper,we propose a flush air data sensing system for subsonic aircraft.Firstly,a pressure database for the FADS system was established by modeling and numerical simulations,and the corresponding error bounds in the range Ma=0.2～0.4 were analyzed based on the model accuracy and wind tunnel calibration.Secondly,a real-time algorithm for the FADS system was developed and integrated into a prototype.Finally,a systematic evaluation of the real-time algori…查看全部>>
