摘要
本文介绍了再生式液体发射药密闭爆发器再生注入装置,给出了能够包括活塞运动与液体喷注之间耦合关系及贮液室中液体惯性的数学计算模型,探讨了液体发射药的雾化燃烧规律,指出了瞬时燃完假定的合理性.在该模型的基础上给出的计算结果能够较好地符合实际情况,有较高的理论和实用价值.
This paper introduces a regenerative injection System of liquid propellant for closed bomb, and gives a mathematical model including the coupling relation between the piston motion, liquid jet and the liquid inertia in the liquid reservoir. Through discussing the spray and combustion rule of the liquid propellant, the paper shows that the instantaneously burnt model is appropriate. The calculation based on this model is suitable to the Practical condition, and the calculation results have theoertical and practical value in a certain extent.
