Abstract:

An investigation was conducted to determine the magnitude and character of tracking errors occurring after firing a rocket at a moving target from a lightweight mount. Six professional gunners with varying degrees of experience fired 3.5-inch rockets from each of three dis tinct types of tracking devices, viz., a two hand wheel system, an electrical rate system, and a viscously-damped, integrated position control system free mount. There was no significant difference in magnitude of tracking error between the free mount and the rate system, with both achieving 0.5 mils RMS error across all conditions of angular rate. The two-hand wheel system was significantly worse with 1.0 mils error at low rates and 2.0 mils error at high rates.
