Range and Accuracy Improvement of Artillery Rocket Using Fixed Canards Trajectory Correction Fuze

This paper presents a two-phase guidance and control algorithm to extend the range improve impact point accuracy of 122-mm rocket using fixed canards trajectory correction fuze. The consists unique glide phase that is activated after flight’s apex. operates in an open-loop configuration where commands are generated increase rocket. In contrast, closed-loop Impact Point Prediction method based on Modified Projectile Linear Theory used as feedback channel correct drift errors. proposed fuze has simple reliable single roll-orientation configuration. model 7-DOF non-linear dynamic dual-spin with mounted at nose. A Monte Carlo simulation rocket’s inertial launch perturbations show can double without changing motor thrust-time curve. At same time, also be improved beyond results unguided
