具有气体动力和物理化学非均匀性的超声速物体绕流(英文)

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。

SUPERSONIC FLOW WITH GASDYNAMIC AND PHYSICOCHEMICAL NONUNIFORMITIES PAST BODIES

The present article deals with the problem of supersonic flow past bodies by a medium with gasdynamic and physicochemical nonuniformities and the effect on the aerodynamic characteristics of bodies. Actions of nonuniformities with respect to temperature profile and to density are discussed in detail.Formation of precursors during interaction between shock wave and thermal layer as well as under the effect of Laser radiation pulse are also carefully described.It should be noted that the input of Laser radiation energy to a supersonic flow may change the flow structure.The presence of regions of higher and lower pressure,emerging from behind the local zones of energy release helps to control the motion of flying bodies.Some measures can be adopted to improve the flying qualities.
