本节要点只有 一、计算通过正激波的流动特性变化

Chapter 4 Incompressible Flow Over Airfoils Of the many problems now engaging attention, the following are considered of immediate importance and will be considered by the committee as rapidly as funds can be secured for the purpose... The evolution of the more efficient

11. 4 PRANDTL-GLAUERT COMPRESSIBILITY CORRECTION The methods that approximately take into account of the effects of compressibility by correct the Incompressible flow results Is called compressible corrections

This chapter mainly deal with the properties of two-dimensional airfoils at mach number above 0.3 but below 1, where the compressibil ity must be considered

一、可压缩流动的基本特征: x The pivotal aspect of high -speed flow is that the density is avariable一一密度是变量

观察超音速下飞行器的升力、阻力的产生及绕飞行器流动的流场细节,包括激波、膨胀波的构型,可以采用以下两种方法: (1) Conduct flight tests using the actual vehicle 进行实际飞行器的飞行试验 (2) Run wind-tunnel tests on a small-scale modelof the vehicle 用飞行器的缩小模型进行风洞实验
