Fin-Opening Dynamics for an 8-inch Gun Launched Extended-Range Guided Projectile
Abstract
The fin-opening dynamics for an 8-inch Gun Launched Extended-Range Guided Projectile (ERGP) were analyzed during the typical 20 to 30 millisecond time span immediately after the missile departed the gun barrel. Lagrange's equations were used to develop a set of governing dynamic relationships using four generalized coordinates including missile roll angle, fin-opening angle and fin bending and torsion deflections. The latter two coordinates provided an elastic representation for accommodating the fin's transient response during the fin-opening process...
