Weapon System Effectiveness Analysis, Optimization and Simulation - Phase I. Volume VIII. Movable Gun Simulation.
Abstract
A two-degree-of-freedom simulation is developed for a fire control system incorporating a movable gun platform having freedom in the pitch and yaw directions. This simulation uses a second-order predictor scheme with a second-order feedback control system for gun positioning. Limited comparison studies were made both with the fixed M 61 and a movable gun system incorporating first-order prediction (lead computing optical sight system). No extensive parametric studies were made in this report; however, for the maneuvers studied, which were made without considerations for the aerodynamic and dynamic penalties, preliminary indications are that considerably more hits are obtained with a flexible gun system than the present fixed gun. Gun parameters that can be varied in the simulation are angular limitations in pitch and yaw, slew rates in pitch and yaw, damping factors on the biaxial servo mechanism controlling the position of the gun, gun weight, and angular stiffnesses for the system. This movable gun simulation was incorporated as a portion of a new fire control package developed for an existing six-degree-of-freedom simulation. (Author)
