The Fire Control Calculation of New Shipborne Gun to Sea Target Based on Terminal Impact Angle Constraint

摘要

According to the characteristics of the controllable muzzle velocity of projectile launched by new shipbome gun, a method of calculating the firing data based on terminal impact angle constraint is proposed. The projectile muzzle velocity is added as a new firing data element of controllable muzzle velocity of shipbome gun, and when striking the sea target in sight, there is a nonlinear relationship between the hitting probability and projectile muzzle velocity. The model of projectile exterior ballistic and the equation of solving hit problem are established and solved, and according to the terminal impact angle constraint of projectile, the range ofprojectile muzzle velocity is determined. Using the derivative free method, the optimal muzzle velocity of projectile is found. Based on terminal impact angle constraint, and making the maximum hitting probability as optimal conditions, the firing data of the new energy shipbome gun weapon can be calculated effectively.
