摩擦阻力是高超声速飞行器气动力的重要组成部分,也是制约高超声速飞行器发展的重要因素,因而对摩擦阻力的准确测量就显得尤为重要。简要介绍了近年国内外与高超声速相关的摩擦阻力直接测量技术的发展状况,同时对中国航天空气动力技术研究院自行研制的两套摩擦阻力测量装置作了介绍,并指出应变式摩阻天平技术是测量摩擦阻力的有效途径之一。文中给出了这两种结构形式摩阻天平的静校结果及其在高超声速风洞中的试验结果,并对结果进行了讨论。
Frictional resistance is an important part of the aerodynamic force of hypersonic vehicles and an important factor restricting the development of hypersonic vehicles. Therefore, accurate measurement of frictional resistance is particularly important. This paper briefly introduces the development of direct measurement technology of frictional resistance related to hypersonic velocity both at home and abroad in the recent years and introduces two sets of frictional resistance measurement devices developed by China Aerospace Aerodynamics Research Institute. It also points out that Strain Frictional Scales Is one of the effective ways to measure the friction resistance. The static results of the two types of frictional balances and their experimental results in hypersonic wind tunnel are given in the paper and the results are discussed.
