智能弹药用新型电控固体推进剂的研究进展
Research Progress of New Electrically Controlled Solid Propellants for Smart Ammunition
摘要
Abstract
In view of the requirements of current solid rocket motor,such as unrepeatable start and stop,difficult to achieve controllable thrust,combined with the advantages of solid rockets and liquid rockets,research institutions at domestic and for-eign have explored an electrically controlled solid propellant with repeated ignition and flameout,adjustable combustion speed and controllable output energy.The research status of new electronically controlled solid propellants at home and abroad is sys-tematically introduced.Firstly,the development of various electronically controlled solid propellants(ammonium nitrate,hy-droxylamine nitrate,lithium perchlorate)at home and abroad is summarized,as well as their applications in micro-thruster,ar-tillery shell igniters and solid engines.Secondly,the effects of formula composition,voltage,current,external ambient tem-perature and pressure on the combustion rate,ignition delay time and mechanical properties of electronically controlled solid propellants are summarized.Then,the start-stop mechanism of electronically controlled solid propellant was analyzed,and the reaction mechanism of ammonium hydroxylamine nitrate and lithium perchlorate based electronically controlled solid propellant was introduced.Finally,the future development of electronically controlled solid propellants is prospected,and it is pointed out that there are still key research directions in the future:enhance the research on the preparation process amplification of e-lectronically controlled solid propellants;design new electrosensitive oxidants to solve the problem of uncontrollable combus-tion under high pressure;carry out experimental research of large-scale electronically controlled solid engines;reveal the cou-pling effect of electric energy and propellant combustion by numerical simulation.62 References are attached.关键词
