进气道出口测量耙是进气道出口流场测量的重要手段,基于环散的飞机进气道出口测量耙的研制较为复杂。在测量耙的研制过程中,根据环散引气散热的功能及纵向波纹管的结构特点,确定了传统耙与附面层耙的布置形式及安装结构,并经过耙臂静强度计算、振动分析及振动试验,结果表明满足飞行试验需求。环散试验件改装及测量耙的设计方法实用、可行,可对类似基于环散的飞机进气道出口压力测量耙设计提供参考。
The measurement of intake port intake rake is an important measure of the flow field at the outlet of the intake port. The development of measuring harvester based on the annular inlet of the airplane is more complicated. In the process of measuring the harrow, according to the function of dissipating the air and the structure of the longitudinal corrugated pipe, the arrangement and installation structure of the harrow and the surface harrow were established. After the harrow strength calculation and the vibration analysis And vibration test, the results show that meet the flight test requirements. The design method of rehearsal and test rake is practical and feasible, which can provide reference for the design of rake outlet pressure measurement similar to the ring-based aircraft.
