Research On The Damage Probability Of Helicopter Gun To Maneuvering Target

The aimed helicopter can fire strike on the ground and air targets on the modern battlefield,and can provide fire strike support to our units.In this paper,the trajectory tracking and prediction technology of maneuvering target is firstly studied and analyzed,with no trace of kalman filter interactive multiple model algorithm of target trajectory prediction,prediction and the result was compared with conventional CV,CT motion model analysis,through filtering processing algorithm for maneuvering target tracking in the process of filtering error and standard deviation;Then both inside and outside of the gun ballistic calculation analysis model is established,and through the numerical simulation analysis of the interior and exterior ballistic gun in the process of explosive load effect on the velocity of the gun and shot Angle velocity,ballistic wind,on the outside of the gun ballistic impact,then analyzes the initial disturbance,the helicopter down wash flow outside the aircraft gun ballistic impact,and establish the air cannon balls scattered and vertical target calculation simulation model of dissemination;Then,the damage probability calculation and analysis model of the aircraft gun to the ground two-dimensional maneuvering target and the air three-dimensional maneuvering target are established,and the damage efficiency of the aircraft gun to the maneuvering target is analyzed.Finally,Matlab and C# hybrid programming technology are used to compile the damage probability analysis software of the air gun to the maneuvering target by modular programming,which is convenient to calculate and analyze the trajectory tracking,internal trajectory,external trajectory,shooting spread and damage probability of the air gun to the maneuvering target.Through theoretical calculation and simulation analysis,the calculation and analysis model of the helicopter cannon’s shooting effectiveness against ground and air maneuvering targets is established,which provides theoretical basis and technical support for the effectiveness analysis,simulated confrontation training and actual combat performance of the helicopter gun.
