Simulation Study Of Gliding Extended Range Rockets

Modern warfare, the range is one of the most important performance indicators rocket,studied in this paper is how to improve the content of rocket range. This paper compares the extended range of other technical means, scheme selection gliding range increased weapons range of ballistic theory, analysis of the various simulation techniques to simulate the effect of canard wing aerodynamic layout,Selection fluent odynamic simulation software simulation,simulation results greatly increase the rocket's range, verify the feasibility of the extended-range mode.This paper introduces the various countries of the world research and development trends of the extended-range missile,presents selected as the main way of gliding extended range projectile way,further comprising providing the barrel muzzle velocity,rocket-propelled auxiliary extended-range way to increase the range of the projectile. Secondly,based on the principles of aerodynamics,this extended-range missile was designed in the shape selection,including wing shape design choice,the choice of the type of layout,tail shape design,the type layout,the main structural characteristics of the missile body and requirements.By fluent simulation,various calculation parameters,indicating that this profile is true and reliable design,practical good. Introduced each projectile control system design issues need to be considered,including the static stability control system,and control the selected feature points,disturbance motion equations,transfer function analysis. Then analyzed missile during flight by the force of circumstances,the establishment of various equations,including the kinematic equations,dynamical equations,mass change equation,geometry equation,control equation. Finally, this paper proposes gliding range ballistic segment control programs,and prototype bombs gliding trajectory analyzes, a significant reduction in the amount of onboard computing automation system at the same time.Gliding Range segment optimal controlprogramme, can achieve close to optimal ballistic missile prototype sub-optimal trajectory of98%, suboptimal and optimal ballistic trajectory difference is small, break optimal control scheme proposed for the gliding extended range rockets on the feasibility of engineering applications.
