潜伏式武器水下减速着陆运动仿真

为了研究潜伏式武器采用减速伞结合舱段分离的方法实现水下安全着陆的可行性,建立了该武器使用减速伞减速及舱段分离着陆时的相关运动过程的数学模型,采用数值计算方法对该运动过程进行了仿真分析,得到了武器减速直至着陆过程中武器及其舱段运动的仿真结果,并对减速伞不同的开启角度对整个着陆运动过程的影响进行了分析。仿真结果表明:通过选择合适的减速伞开启角度、开启深度、舱段分离深度以及钢缆长度参数组合,基本可以实现武器的安全着陆。

Simulation on Underwater Landing Motion of Latent Weapon

In order to study the feasibility of latent weapon safely landing underwater by using parachute and separating into parts,the mathematic models were established on the basis of the analysis of the whole motion process including the deceleration and the weapon landing. The characteristics of the deceleration motion were numerically simulated. The simulation results of the motion of weapon and bay section in the process of weapon decelerating until landing were obtained. The effect of the parachute opening angle on the whole landing process was analyzed. The simulation result shows that this scheme is feasible for the weapon safely landing by choosing the appropriate parameters such as opening angle of parachute,the opening depth,the separation depth of bay section and the length of steel cable.
