大口径火炮发射装药点传火模拟试验装置的研究

设计了一种大口径火炮发射装药点传火系统的模拟试验装置，用于测定大口径火炮装药点传火实体的燃烧特性。通过在该模拟试验装置上进行不同点传火结构方案的试验研究，筛选优化出点传火结构方案，进行了装药内弹道验证试验，测得膛压曲线光滑，压差曲线呈衰减状。实验说明该模拟装置，可以对不同点传火结构方案进行对比、筛选，为大口径火炮装药点传火结构设计以及火炮射击试验初期的安全评估，具有指导作用。

Research on Simulation Testing Device of the Ignition System for Large Caliber Propellant Charging

A simulation testing device of the ignition system for large caliber propellant charging was designed to measure the combustion characteristics oi tne system. The tests for different ignition struc?tures were done by the simulation testing device. The optimized ignition structures were screened by the simulated results, and a series of the inner ballistic tests was carried by the two ignition structures. The results of the tests verify that the measured chamber pressure curves by the screened ignition structure are smooth and the pressure difference between the curves is attenuate. The simulation test?ing device can be used for screening the different ignition structures and guiding the ignition structure design and the safety evaluation of original firing test.
