The High Energy Missile Technology Demonstrator (HEMi TD) is a project to demonstrate the lethality of a compact hypervelocity kinetic energy missile to provide light armoured vehicles sufficient lethality to destroy a main battle tank. In support of the development of the HEMi concept, analysis of the missile performance has been performed using modeling and simulation of the engagement. A nominal simulation using constant disturbances composed of boost motor thrust misalignment and dart separation effect permitted the evaluation of the nominal kinematics performance of the missile. Then, a Monte Carlo simulation using randomly generated disturbances was used to evaluate the dispersion and probability of hit of the missile. The rocket motor having been designed for a missile mass of 23kg, the actual mass of 25.8kg leads to a maximum velocity of Mach 5.6 while the objective was Mach 6.5. However top speed is obtained at a range of 325m thus achieving a minimum engagement range better than the 400m objective. The Monte Carlo simulation results demonstrate that the hit probability of 95% required by the customer can be achieved for all target ranges. However, the missile model does not account for guidance sensor induced error. It should be expected that modeling the guidance sensor accuracy would increase the missile dispersion at long ranges. Also, further work is required to estimate the probability of kill achieved by the proposed segmented rod.
