Research on the Missiles Hanging Brace Interference Test in High-speed Wind Tunnel

张线支撑作为一种特殊的支撑方式能够实现某些特殊试验,目前主要应用在低速风洞,文中旨在研究张线支撑高速风洞气动力影响规律和探究张线支撑在高速风洞应用的可行性。主要介绍了弹箭模型高速风洞张线支撑总体研究方案和模拟试验方案,并针对试验方案进行了数值方法及风洞试验验证。试验结果表明,弹箭模型高速风洞张线支撑干扰试验方案可行,张线支撑干扰较大。

Hanging brace is used as a special way to achieve some special test,mainly used in low speed wind tunnel at present. This paper aims to study the feasibility of hanging brace in high speed wind tunnel and the aerodynamic influence law effect by hanging brace. This paper mainly introduced overall research scheme and the simulation scheme of the missiles in high speed wind tunnel test. Then uses numerical method and the wind tunnel test were carried out to verify it. The result shows that the research scheme of missiles hanging brace interference test in high speed wind tunnel is feasible. The interference by hanging brace is big.
