Tracjectory Simulation And Process Optimization Design Of Artillery Terminal-Sensitive Projectile

Terminal-sensitive projectile has wonderful anti-amor capability then meets with much recognition and be equipped for more and more nations.This thesis establish the Terminal-sensitive projectile trajectory model standing on the overall design and.The airborne endurance is reduced and the system reliability is increased by optimization design of function process parameter.This thesis analyzed and established the process of submunitions separateness,the relationship of reduce velocity and rotate and stable scannning motion.By analysis and simulation,it found some results as these:the loosen time of drag parachute mostly related with the mass value of projcetile bottom and submunitions,drag parachute characteristic in the projectile bottom and the safety seperate distance between projectile bottom and submunitions.At the same time,the error of unchain sheaf rope time should be considered.Rotating parachute trajectory characlistic is related on the effect of reducibility wings,drag parachute’s characlistic and the mothod of finish the drag parachute trajectory.The velocity of reject effect is too small to be ignored in the design of function process.And Point out the principle of high of starting stable scanning motion,and the anylised result shows that system stability,error of high detect and error of the time loosening rotate parachute has little effect on the high of starting stable scanning motion.For the time-control mode unbolting rotate paratrute,the high of starting stable scanning motion rest with the distribute of high of projecting,the time unbolt drag parachute and the distribute of resistance characlistic of drag parachute.The result of system process test shows that the optimization design increase the systerm process reliability,viability and efficiency of the Terminal-sensitive projectile.The study of this thesis can be immediate used in the Terminal-sensitive projectile system design,and it has guidance effect on other platform such as rocket,missile,aerial bomb and motar projectile.
