Abstract: Sanders, a Lockheed Martin Company, is leading the development and integration of the Vehicle Health Management (VHM) system for Lockheed Martin's VentureStar Reusable Launch Vehicle. The primary objective of this effort is to provide an automated health status and decision-making system for the vehicle. A detailed simulation of the VHM system on RLV is currently being developed using the Foresight Design and Modeling Tool. The simulation will consists of models of key components of the RLV VHM system. An effective detailed system simulation will allow for system and design engineering, as well as program management teams, to accurately and efficiently system designs, analyze the behavior of current systems, and predict the feasibility of making smooth and cost-efficient transitions form older technologies to newer ones. This methodology will reduce program costs, decrease total program life-cycle time, and ultimately increase mission success. !5
