水雷伞的飞行轨迹研究

据水雷伞实测的弹道参数扣除气象条件的影响，求得无风弹道，作为实战投弹的依据。根据无风弹道修正的结果，求出弹伞系统的阻力特征ＣＡ值，作为研究降落伞开伞段理论的基础数据。然后将求出的ＣＡ值代入运动方程算出理论弹道，再把理论弹道与无风弹道相比较，当误差不大时说明理论弹道的计算方法是正确的，可用于一般水雷伞计算理论弹道用。

Study on the Flight Path of Mine Parachute

The paper finds the trajectory of mine parachute under no wind condition according to the measured trajectory parameters deducting the effect of meteoroingical condition during laying mines with parachutes. Then according to the effect of correction to no wind trajectory,the drag characters (CA) of bomb-parachute system is found as foundanon numbers of the open parachute theory. Then inserting CA value in motion equation we may calculate theoretical trajectory. By comparison of the theoretical trajectory with no wind trajectory, the difference shows the correctness of the methord, and it may be applied to calculate theoretical trajectory of general mine parachutes when the difference is smaller.
