子母弹战斗部抛撒装置内弹道参数研究

Interior Ballistic Parameters of Submunition Dispensers

分析了子母弹燃气抛撒装置的结构原理,根据气动原理,利用准两相流理论,计及火药气体和正在燃烧的火药固体的两相流动。研究了星形隔框式子母弹战斗部的抛撒过程,最终可得到p-t曲线和子弹抛撒速度。

Structural principles of a submunition dispenser are analysed. Based on the principle of aerodynamics, an analysis is given for the process of ejection of a submunition warhead equipped with star-shaped frame. In the analysis the quasi-two-phase flow consisting of the combustion gas from the gunpowder and the gunpowder pellets in their process of combustion are taken into account. The p-t curve and the ejection velocities of the submunition can be derived.
