常规弹药弹道修正用推冲器的国内外研究概况

推冲器在国外已广泛用于导弹、炮弹和火箭弹等常规兵器的弹道修正,近年来,它在国内也逐渐成为一个热门的研究领域。本文主要总结了国外几种典型推冲器的结构、性能和应用情况,简要介绍了国内的最新研究进展,并展望了推冲器研究的未来发展方向,认为以半导体桥或金属膜桥作为发火元件、以火工药剂或采用新装药工艺的常规固体推进剂作为输出装药将是今后几年对燃气喷流推冲器进行研究的一个发展方向,另外,开展喷射质量块推冲器的应用研究也将成为国内外在弹道修正用推冲器研究领域的一个重要内容。

Review on Impulse Thruster Used for Trajectory Correction of Conventional Munitions in Domestic and Abroad

In many foreign countries,the impulse thruster(mainly combustion-gas jet type) has been widely used in some conventional munitions for trajectory correction including conventional missiles,glide bombs,cannon launched munitions and rockets and the like.In recent years,it has also been a great interest in researching the impulse thruster used for improving the ballistic accuracy of some projectiles in our country.The studies on the structures,performances and applications of some typical impulse thrusters developed by some foreign countries were simply summarized.Besides,the up-to-date progresses in this research field in our country were also introduced.In addition,some opinions on the future impulse thruster were put forward: firstly,to use semiconductor or metal-film bridge as the element for igniting,and compositions mainly used in initiators or pyrotechnics as output charge,or to use conventional propellants as output charge by improving the charging technology,may be one of the trends for future combustion-gas jet type impulse thruster;secondly,carrying out some basic researches on slug-shot type impulse thruster will be an important part in the research field of thruster in domestic and abroad in the near future.
