The translational effects of gas streams, which form after the triple-shock configurations at Mach reflection of blast waves with normal main shock (so-called stationary Mach configurations), were analyzed. Unlike in the case of an elevated explosions of fuel as rocket starts in initially stagnant air, which is considered here as a private case, it was supposed that this shock-wave structure moves in a preceding flow with arbitrary velocity (and corresponding flow Mach number). Analyzing relations of the dynamic pressures across the slipstream, which emanates from the triple point of the Mach reflection, it was shown that the flows after the triple-shock configuration usually differ much in their translational action on surrounding objects. It was found and discussed that some configurations drag the objects initially situated above and below the triple-point trajectory in opposite directions. Moreover, the “trigger” structure was found that remains previous flow drag action on the object above the triple-point trajectory, but switches it to exactly opposite one, if the object is situated below the triple point.

冲击波在轨道站有限空间内的三激波构型的极端平移影响


分析了具有正常主激波的爆炸波（所谓的稳态马赫构型）在马赫反射三激波构型后形成的气流的平移效应。与火箭在最初停滞的空气中启动时燃料高爆炸的情况不同，这里被认为是一个私人案例，人们认为这种冲击波结构以任意速度（和相应的流马赫数）在前面的流动中移动。分析从马赫反射的三相点发出的滑流上的动态压力的关系，结果表明，三激流配置后的流动通常对周围物体的平移作用有很大差异。发现并讨论了一些配置将最初位于三点轨迹上方和下方的物体沿相反的方向拖动。此外，发现“触发”结构保留了对三相点轨迹上方物体的先前流动阻力作用，但如果物体位于三相点轨迹下方，则将其切换到完全相反的流动阻力作用。
