Portable Anti-helicopter Rockets Cfaw Computer Simulations

This thesis mainly analyzes the elements and characteristics of fuze-warhead system of anti armed helicopter portable rocket bomb, modifies the equivalent model with regard to the vital parts and the unitary body of MNT-24 armed helicopter, advances the design method and numerical value of fuze parameters and warhead parameters which can greatly influence the fuze-battle part cooperation character, and then establishes the mathematic model of fuze-warhead coordination of spherical performed fragmentary warhead equipped with laser-proximity fuze, including fuze simulation model, the model of calculating the fragment number of hitting target and the model of calculating the damage effect on the target. A MATLAB computer programme has been given, which can compute the fuze optimum burst point, the optimum time delay and the unitary body damage probability on all projectile-target encounter conditions. Based on the Monte-Carlo method, the fuze optimum burst area and the optimum time delay are simulation calculated. Moreover, the statistic law of the unitary body damage probability with both fuze parameters and warhead parameters changing is obtained. The simulation results advance the rule of designing fuze parameters and warhead parameters of anti armed helicopter portable rocket bomb.
