Applications Of Trajectory Simulation On Effectiveness Analysis Of High Rate-of-fire Antiaircarft Weapon System

The traditional antiaircraft weapon system is used to intercept low-speed targets. If the flying targets at some point in the future through an area are estimated, numbers of guns set fire to this area to expect to destroy the targets. But now the targets have the features with small and fast. The performance of this weapon system is not very high. Now the antiaircraft weapon system which is used to defense missile has been moving in the direction of long bursts and high rate of fire. This new weapon system can intercept the target which speed is more than Mach 2 by continuous shooting. Therefore, the design of ballistic which matches the new weapon system also need to follow up.The main research of this paper is the small and medium caliber high rate-of-fire artillery. First,by establishing the solving model of high rate-of-fire antiaircarft weapon system which hits the target, the hit probability at each point in advance is analyzed, and the model of hit cumulative probability about antiaircarft weapon system and integreted missile and gun on all fairways is established. The trajectory simulation technology is used in weapon system effectiveness analysis. Second Trajectory simulation program written by software is used to analyze the effects of the parameters of exterior ballistics and interior ballistics. The solid model of the weapon is drew by using UG4.0, and the ANSYS software is employed to analyze the impact of structural vibration and analyze the effects of Gatling gun speed, half cone angle, the coriolis force on the muzzle. In terms of improving the effectiveness of weapon systems, the technical of hitting the targets in the same section which can improve the hit probability of weapon system is proposed. The technical of sections interception is analyzed in this paper. The model of the cross-section interception technology is established.Finally, a weapon system effectiveness evaluation of theoretical high rate of fire artillery and integreted missile and gun with the model of hit cumulative probability is established preliminary.The research of this paper has important significance in antiaircarft weapon system and integreted missile and gun.it is used for fire control system.
