摘　　要：对于一些高性能飞行器(如飞翼布局飞行器),仅采用安装在机头表面的测压孔的FADS系统方案.某些情况下不一定能够给出较为准确的飞行姿态数据;针对飞翼布局飞行平台对高精度迎角、侧滑角的依赖性.给出了一种采用安装于机头表面的测压孔和机翼前缘的测压孔相结合的FADS系统方案,推导了其空气动力学模型,并用BP神经网络拟合出了迎角和侧滑角的修正曲线,结果表明该方案能够满足系统精度的要求。For some high performance aircraft, for example , flying wing , FADS system which is only instrumented on the nosecap surface sometimes can＇t provide airdata correctly enough. In allusion to flying wing vehicle which needs more accuracy angle of attack and angle of sideslip signal, a kind of FADS system whose pressure orifices are instrumented both on the vehicle nosecap and on the wing leading edge are presented, then the aerodynamic model is introduced and the calibration curve for angle of attack and angle of sideslip using BP neural network are also given, result shows the system can provide the measurement precision we need.
