颗粒模压发射药装药的点传火性能
|
摘要
以粒状高能硝胺发射药为基础药,经过表面钝感、包覆、模压处理,制备颗粒模压发射药。设计底部结构和传火管结构两种点传火结构方案,利用30 mm高压模拟火炮,研究颗粒模压发射药装药的点传火性能。结果表明,与底部结构相比,传火管结构将颗粒模压发射药装药的点火延迟时间缩短15.2%,膛内最大负压差降低8.41 MPa,装药床受到的最大挤压力减小11.93 MPa。传火管结构方案使颗粒模压发射药装药具有良好的点传火性能。
Graunnolded gun propellant was prepared based on nitramine propellant by surface-deterring,surface-coating,and grain-molding.Two ignition schemes including bottom configuration and central core igniter were designed.Results show that compared with the bottom configuration,ignition delay time shortens 15.2%and the maximum negative pressure difference decreases 8.41 MPa of central core igniter,and the maximum extrusion process of the propellant decreases 11.93 MPa,which indicate that central core igniter ignition scheme can bring perfect ignition performance for grain-molded gun propellant charge.
