本文研究的问题是超声速气流流过物体时产生的气体动力和物理化学非均匀性及其对物体空气动力特性的影响。就有关流动非均匀性对温度剖面和密度的效应作了详细探讨,还仔细描述了激波与热层相互干扰时以及在激光辐射脉冲的作用下先行激波生成的情况。值得指出的是超声速气流中加入激光辐射能可能改变流动结构,在局部能量释放区域后面呈现的较高和较低压力,有助于控制飞行中物体的运动。可采取某些措施以改进飞行品质。
The problem studied in this paper is the aerodynamic and physico-chemical non-uniformity of the supersonic gas flowing through the object and its effect on the aerodynamics of the object. The effects of flow inhomogeneity on temperature profile and density are discussed in detail. The shock wave generated when the shock wave and the thermal layer interfere with each other and the laser radiation pulse is applied. It is worth pointing out that the addition of laser radiation to the supersonic gas stream can alter the flow structure and the higher and lower pressures that appear behind the local energy release area help to control the movement of objects in flight. Some measures can be taken to improve flight quality.
