摘要
对传统"硬式"支撑系统和"软式"张线支撑系统,以及绳牵引并联支撑系统的支撑形式进行分析.对比实验结果表明,低速风洞试验的静导数测量采用"软式"支撑系统较好,张线支撑系统只能实现静导数测量;绳牵引系统不仅具有张线测量静导数时的全部优点,而且还可以实现单自由度的和多个姿态角组合的飞行器模型的多种振荡运动时的动导数测量.在传统风洞试验基础上,结合绳牵引系统的自身特点解析,归纳绳牵引支撑风洞试验系统的静导数和动导数的气动导数解算原理.
After analysis of the traditional strut suspension system,cable mounted suspension system,and wire-driven parallel suspension system,it can be concluded by comparison that it is a more suitable way to use cable mounted suspension system to measure the static derivatives of the aircrafts in low-speed wind tunnels but it can only measure that,and wire-driven parallel suspension system not only owes all of the advantages of cable mounted suspension system when measuring the static derivatives,but also it can measure the dynamic derivatives when the aircraft performs the oscillations including single degree-of-freedom oscillation and other oscillations with the multi-attitude combination.Based on the principle of traditional wind tunnel tests and the inherent characteristics of wire-driven parallel suspension system,the summary of calculation principle of aerodynamic derivatives including static and dynamic derivatives of the aircraft in wire-driven parallel suspension system for low-speed wind tunnels is made.
