shock wave drag

常见例句

However, the rings only reduce the pressure drag by 0.4% because the rings disturb the external flow and increase the shock wave drag.
但由于凹环对气流的扰动增加了激波阻力，故包含底部阻力及激波阻力的压差阻力减小并不显著，仅为0.4%。

In the second design step, improvement of wing's aerodynamic characteristic is mainly depended on the weakening of shock which reduces wave drag during the wing section optimization.
在平面形状优化基础上，在机翼容积不变约束下，再采用剖面翼型优化设计，通过机翼剖面细微变化弱化较大马赫数下的激波、减小激波阻力。
