摘　　要：动能拦截弹(kinetic energy interceptor,KEI)主要用于拦截在助推段、上升段以及中段飞行的中远程和洲际弹道导弹,具有高速、高加速的特点。通过文献资料的研究分析和建模仿真,对KEI导弹的总体参数、气动参数、动力参数进行了反设计和研究,并对KEI导弹的飞行性能和拦截性能进行了仿真,结果表明:KEI导弹能够在约60 s内加速至6 km/s,并对典型目标具备在助推段/上升段拦截弹道导弹的能力,对国内拦截武器的发展和研究具有参考意义。Kinetic energy interceptor(KEI)is mainly used to intercept medium-range and intercontinental ballistic missiles flying in the boost phase,ascent phase and midcourse,with the characteristics of high speed and high acceleration.Based on the research and analysis of literature and modeling simulation,this paper conducts reverse design and research on KEI missile′s overall parameters,aerodynamic parameters and dynamic parameters,and simulates KEI missile′s flight performance and interception performance.The results show that KEI missile can accelerate to 6 km/s in about 60 s.It also has the ability to intercept ballistic missiles in the boost phase/ascent phase for typical targets,and has reference significance for the development and research of domestic interceptor weapons.
