飞行器大气数据传感器布局分析设计

摘要

在对大气数据系统的功能和大气数据传感器的基本工作原理进行介绍的后,详细的分析了大气数据传感器安装要求.经过理论分析,提出了一种利用计算机仿真CFD软件定位大气数据系统传感器位置的设计方法.并以某型号飞行器为例,从静压的要求入手,详细的阐述了数据的建模,确定飞行器构型,选点,数据对比分析,确定最终位置和角度.本方法对于飞行器设计初期,特别是风洞试验和试飞前大气数据探头的位置确定具有实际意义.%After describes the function of Air Data systems and the working principle of Air Data sensors, it analysis the instal-lation requirements of the sensors in detail. During theoretical analysis, it provides a solution for selecting a good location of the air data sensors on the airplane with help of Computed Fluid Dynamics software. And it use the an example of an airplane type, start form static pressure requirement, introduces the data modeling, selects airplane configuration, selects the useful grid point, compares result and analysis, finally get the appropriate location. At the start of an airplane program, this solution is useful, especially before wind tunnel test and flight test.
