用拉氏量计和分析技术研究固体推进剂冲击波作用过程

A LAGRANGE GAUGE AND ANALYSIS TECHNIQUE FOR STUDYING PROPERTY OF SHOCKED SOLID PROPELLANTS

本文建立了适合于研究固体推进剂冲击波作用过程的拉氏量计和分析技术,应用这种技术能清楚地表现固体推进剂内部状态变化过程和化学反应过程。并用这种技术研究了聚硫复合推进剂、丁羟复合推进剂、双基推进剂和改性双基推进剂冲击波转爆轰和爆轰过程。结果表明,复合推进剂与双基和改性双基推进具有明显不同的状态变化过程和化学反应过程。

A Lagrange gauge and analysis technique were developed in order to study response of solid propellants to shock loading. Using this technique the development of shock front and flow field behind the front can be illustrated. Shock detonation transition (SDT) and detonation process of DB, HMDB and two composite propellants have been studied.
