拉杆活塞式发射装置内弹道建模与仿真

为了进行小尺寸、长行程、低过载发射,设计了一种拉杆活塞式发射装置.根据经典内弹道理论,采用集总参数法对混合装药下舍高低压药室的发射过程建立了内弹道模型;采用四阶龙格库塔法对该模型内弹道过程进行了求解.数值计算结果表明,拉杆活塞式发射具有较低的最大膛压和发射过载,但随着拉杆数量和质量的增加,对弹丸做功效率有所下降.拉杆活...

Modeling and Simulation of Interior Ballistics of Slide Rod Piston Launching Device

A slide rod piston launching device was designed to perform a type of new launching with low acceleration,long travel-length and no gas leakage.According to the classical interior ballistic theory,lumped parameter method was applied to establish the model in which the mixed charge was considered for the low and high pressure launch of the slide rod piston launch device.Four-step Runge-Kutta method was used to solve the equations of the model.The numerical calcuation result shows that the launch of slide rob...
