| In modern battle field the requirement for the precision of weapon is harder and harder, as not only decides the victory of the war but also come down to decrease of non-battle object. The trajectory correction projectile is cheap precise guided ammunition comes forth in 1980's.The integrated technology of the two-dimensional trajectory correction aiming at the air-object is studied on the basis of analyzing and summarizing the present situation and developing tendency of trajectory correction projectile of inside and abroad. A new structure of electromechanical actuator is offered and its kinetic model is made according to the control principle of the two-dimensional trajectory correction projectile. Based on the xxmm weapon of navy, we set up the easy model of the trajectory, analyze the ability of the canard, design the theory sample and the control system, and process the captive test.Based on analyzing and experiment, this actuator has the advantages of low load, quick response, small volume and credible action. It is very suitable to tiny rolling projectile. |
