超高速自由飞弹道靶是最重要的现代气动试验设备之一。由于它是超高速范围内唯一能同时模拟再入飞行器马赫数、雷诺数和焓值的一个设备,而且与风洞类设备相比有洞壁干扰较小,无模型支承干扰、不存在流场品质好坏问题和在一个设备上仅通过对模型发射参数的调整,即能实现很宽的马赫数模拟等优点,因此,在高超声速气体动力学和再入气动物理学研究中,能发挥特殊重要的作用。
Ultra-high-speed free-flight ballistic target is one of the most important modern pneumatic test equipment. Because it is the only device in the ultra-high speed range that simulates the Mach number, Reynolds number and enthalpy of the reentry vehicle at the same time, and has less interference with the tunnel wall than the wind tunnel equipment and no model support interference, there is no flow field Good or bad quality problems and the fact that on a single device only by adjusting the emission parameters of the model, that is to say a wide Mach number simulation can be achieved. Therefore, in the study of hypersonic gas dynamics and reentry aerodynamics, Important role.
