一种安装在飞行器机翼前缘的FADS系统方案研究
摘要
大多数大气数据传感(FADS)系统都是采用安装在飞行器头部表面的压力传感器阵列来感受大气压力分布
为了避免FADS系统对航电系统和火控雷达系统的影响
给出了一种安装在飞行器机翼前缘的FADS系统方案
推导了其空气动力学模型
给出了上洗角的修正公式
通过风洞测试曲线和理论曲线的比较可以看出:W-FADS系统在小迎角范围内精度较好
对测量大气数据是可行的。
Abstract
Most FADS systems use a matrix of pressure sensors installed on the vehicle nose to measure the pressure of the vehicle surface.To avoid the FADS system’s effecting on the operation of the avionics or fire control radar system
a kind of FADS system which is instrumented on wing leading edge is presented
then the aerodynamic model is introduced and the upwash calibration angle is given.At last a comparison of the predicted upwash and experimentally derived upwash calibration values is presented
and it is conclude that the W-FADS system’s performance is good during low angle of attack and it is a flexible way to measure airdata.
