Trajectory Correction Projectile Structure Of The Servo And Control

In modern battlefield 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 conies 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 China 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. A sample of the actuator and its control system are designed for 100mm ammunition.On the results of analyzing and simulating, this actuator has the advantages of low load, quick response, small volume, credible action and high output torque. It can drive four rudder faces by only one electromotor and is very suitable to rolling projectile.
