双药室装药实现能量补偿的技术研究

Study on Energy Compensation Technique of Double Chambers Charge

从理论上分析了双药室装药方式实现能量补偿、增大p-l曲线作功面积的可行性,并进行了相关实验。主装药室和附加药室的装药量分别为32和10g,控制主装药室和附加药室的点火时间差为1.5ms。结果表明,双药室装药p-l曲线的作功面积较普通装药明显增加,在150MPa附近出现了压力平台,炮口初速提高了56.3m/s。采用双药室、适时补充能量的装药方式能够增大p-l曲线的作功面积、实现压力平台、提高炮口初速。

The feasibility of double chambers charge forming energy compensation and increasing area underneath the p-l curve have been discussed theoretically and the relative experiments were done. Main chamber charge mass and subsidiary chamber charge mass adopted are 32 gram and 10 gram, respectively. The controlled ignition time difference between main chamber and subsidiary chamber is 1.5ms. The experimental results show that the area underneath the p-l curve of double chambers is larger than that of ordinary charge, a pressure platform appears around pressure 150MPa, and the muzzle velocity is increased by 56.3 m/s. The double chamber charge of compensated energy made the pressure platform really appear, and the area underneath the p-l curve and the muzzle velocity increase.
