Study on the Method of Separated Trajectory Correction of Fuze for Spin Projectiles

The method of separated trajectory correction of fuze for spin projectile is researched.Computing the error of projectile trajectory is very important to projectile trajectory correcting while the projectile is flying.Based on the trajectory being separated into several parts in the drop part of trajectory,a quickly computing model of trajectory according to Taylor expression is given,then the correction force is computed quickly.The computing method of correction force and time of the canard correction mechanism is discussed,and a feasible correction scheme of correction fuze for spin projectiles is given.
