Study On The Damage Of Floating Targets By Fragmentation Combatants

As a kind of aircraft,the floating target was adopted by the military of many countries,and deployed in the border area,with the characters of low cost,wide monitoring range,long delay time,to perform monitoring of neighboring countries and low warning tasks.It made a great threat to national territorial security problems.Therefore,it is an urgent problem to attack the floating target efficiently.In this paper,the problem of damaging stratospheric floating target by fragment warheads is studied taking a typical fragment warhead model as an example.(1)To analyze the characteristics of the fragment field of the fragment warhead take natural fragments and prefabricated fragments as examples.The mass distribution,spatial distribution,initial velocity and velocity attenuation rules of the fragment field are obtained.Select specific kinetic energy criterion as the damage criterion for floating target destroyed by fragment warhead base the floating target characteristics.The equivalent model of the key parts of the air target are established,and the the damage condition is studied.The results show that about 83%of the natural fragments can penetrate both the target skin and the radar,make effective damage;the prefabricated fragments field can damage the target different incidence angles.(2)Establish the dynamic distribution density function of the fragments field.By the calculation of the dynamic distribution density function based MATLAB,shows that,under the dynamic explosion condition,the dynamic distribution density will decrease with the increasing of the fragments flying distance.,the dynamic distribution density will decrease with the increasing of the dynamic fly-scatter direction,increase with increasing of the frame velocity of the warhead under the same fragmentation flying distance.(3)Deduction the mathematical model of the killing space and the damage probability of the floating target attacked by the fragment warhead.the destruction probability and killing space are calculated through MATLAB simulation.The damage probability will increase with the increasing of the intersection angle of target and warhead when the warhead is at a certain height,the different intersection conditions and the fragment flies at a certain distance.The killing space will increase as the increasing of the fragments number,the fragment initial velocity,and the explosive Gurney constant increase,decrease with the increasing of fragment shape coefficient and shell thickness.
