The Study On The System Technology Of Light Image Guidance Multipurpose Missile

With the development of detection and control technology, and the in-depth applicationof high-energy propellants, explosives, and new composite materials, As well as thedevelopment of new damage, making the size and weight of the anti-tank missiles are gettingsmaller and smaller, which allows man-portable became possible. The trend is fire and forget,can attack tanks, armored vehicles but also can attack ground fortifications and low-altitudeaircraft.In this paper, the overall program is preliminary design of the system of image-guidedanti-tank missile, by analyzing the visible and infrared-guided principles and targetrecognition technology, the seeker parameters are preliminary designed, the guide way andtrajectory overall program are determined, the two level shaped charge warhead programwhich can destroy of reactive armor is designed at the same time.In order to make anti-tank missiles can take a different trajectory attack, achieving levelflight and Bending summit, which will make the maximum damage efficiency, twin-engineand aero composite control scheme is selected, two kinds of aerodynamic shapes which arerudder and canard would be designed, the external flow field is simulated and analyzed byusing CFD program, aerodynamic parameters are obtainedFor two kinds of aerodynamic control which are rudder and canard, the anti-tank missileflight dynamics model is established based on based on the theory of rigid trajectory, theaffect of two kinds of aerodynamic layout the different rudder deflection angle and the timeof start controlling is simulated of trajectory, two kinds of trajectories are achieved bymatching the parameters of engine and control strategies reasonably. By designing areasonable overall program, aerodynamic layout and trajectory control strategy,thesimulation results show that anti-tank missiles can be achieved the level trajectory andBending summit trajectory for different targets, which has some reference to the man-portable multi-purpose image-guided anti-tank missile design.
