Abstract

To improve concentration of projectiles, one-dimensional trajectory correctional projectile with drag brake was studied. The effect on aerodynamic performance of drag brake to the projectile was analyzed, and the method controlling the action time of drag brake was presented. By numerical simulation, the aerodynamic performance for different structure of drag brake was studied where the outer height of the drag brake was same while the mounting position was different, then the additional drag coefficient from different drag brake was got, which can be referred for the design of aerodynamic structure of one dimensional trajectory correction projectile. At the same time, using the selfprogramming software, the effect on trajectory correction capability of action time of drag brake was analyzed, and the computing method of the action time of drag brake was studied. The studying result can be the fundamentals for the exterior ballistic trajectory design of one-dimensional trajectory correction projectile.

Key words： one-dimensional trajectory correction projectile; aerodynamic characteristics; drag brake; trajectory correction capability
