空降兵降落过程的动力学分析与数值计算

Dynamic Analysis and Numerical Computation of the Airborne Force Landing Process

从空气动力学的动力学相似原理出发 ,由量纲分析中的π定理推导出了雷诺数 ,并通过不同情况下雷诺数的分析 ,计算了垂直降落时的速度、距离遵循的规律。

Based on the air-dynamics elementary principle, namely dynamics similar principle, the Reynold's number is derived from the π theorem of the dimension analysis. Through analyzing the Reynold's number in different conditions, the formula for calculating the landing velocity and falling distance in perpendicular falling is derived.
