Abstract
Rocket launching from shoulder-supported systems produces a jolt associated with the change of the launcher mass and weight when the rocket exits the tube. The effect is therefore central to the design of shoulder-supported rocket launcher simulators. An advanced design model of a physical weight unloading simulator has been developed to simulate operation of Javelin, an air defence weapon in use by the Canadian Forces. The developed concepts and systems, however, can be generalized and adapted to facilitate similar training requirements with other shoulder supported systems. The simulator is based on the use of the RObotic Muscle-like ACtuator (ROMAC) to achieve the weight unloading effect at the shoulder and arms of the operator. It has a ceiling-mounted overhead gantry X-Y table servo system that delivers precise unloading action independent of the operator's position/orientation. It allows operator movement within a large 100 ft2 area and it keeps the lifting cable vertical. The system offers rapid response and high fidelity unattended operation.
