Research On Combat Capability Of A High-speed Projectile

The development of modern military technology has increasing demand for weapons of high speed ang high kinetic energy.The muzzle velocity of conventional artillery has nearly reached the physical limit,and an electromagnetic gun was adopted to shot the projectile at very high speed,which makes projectile have tremendous kinetic energy and strong damaged power.In this paper,the performance of the high-speed projectile shot by electromagnetic gun is researched.First,Considering the curvature of the earth and introducing relevant coordinate system,the model of the high-speed projectile is built.Under different initial flight path angle,the range and terminal velocity are discussed.The stability of projectile is analyzed when it flys very high based on the curre of attack angle.Secondly,Considering the initial disturbance,random wind disturbance and error of firing data,the model of firing accuracy is built and the firing accuracy is analyzed under firing data error and dispersion error based on Monte Carlo method.Thirdly,a overload autopilot is designed adopting automatic control theory and the effectiveness of of it is verified.Finally,considering such factors as the speed and flight altitude of typical targets,maximum detection range of radar,available acceleration of high-speed projectile,the kill zone and launch zone of high-speed projectile are analyzed and calculated.
