静压孔传感器用于测量飞机飞行所在高度的大气静压,通过大气数据计算机得到飞机的飞行高度和飞行速度。本文通过CFD方法对两种国外现役机型的机身静压场和静压孔气动特性进行研究,结合静压孔传感器的使用特点及设计要求,可以获得使得静压孔传感器修正规律简单的布局位置,为静压孔传感器在试飞修正中获得高质量的测量精度奠定良好的理论设计基础。
The static pressure hole sensor is used to measure the atmospheric static pressure at the altitude where the aircraft flies. The aircraft’s flight altitude and flight velocity are obtained from the air data computer. In this paper, the CFD method is used to study the hydrostatic pressure field and the static pressure hole characteristics of the two overseas active models. Combined with the characteristics and design requirements of the static pressure hole sensor, we can obtain the simple layout of the static pressure hole sensor correction law Position, for the static pressure hole sensor in flight test correction to obtain high-quality measurement accuracy laid a good theoretical basis for the design.
