对为高速度的飞的车辆的表面的飞行器热的加热的凉下来电影的技术的可能的申请被讨论。这种技术广泛地在煤气的汽轮机片的热保护被使用了。它在这份报纸被显示出由把这种技术用于高速度的飞的车辆，工作原则是根本上不同的。为二个模型问题的数字模拟被执行支持争论。除热保护以外，可估计拖减小被发现是另一有利效果。为第二个模型问题，即，在一个范围锥上的为一扇光窗户的煤气的冷却，这部电影的水动力学不稳定性被线性稳定性分析学习观察 laminar 狂暴的转变的可能的出现。

英文摘要：

The possible application of the film-cooling technique against aero-thermal heating for surfaces of high-speed flying vehicles is discussed. The technique has been widely used in the heat protection of gas turbine blades. It is shown in this paper that, by applying this technique to high-speed flying vehicles, the working principle is fundamentally different. Numerical simulations for two model problems axe performed to support the argument. Besides the heat protection, the appreciable drag reduction is found to be another favorable effect. For the second model problem, i.e., the gas cooling for an optical window on a sphere cone, the hydrodynamic instability of the film is studied by the linear stability analysis to observe possible occurrence of laminar-turbulent transition.
