Generation of Consistent Rotorcraft Dynamics Models for Life Cycle Simulation Support

"Simulation models of rotorcraft are used in a wide variety of Army applications. Conceptual Design applications use models of the sensitivity of performance to design parameters. Preliminary and detailed design applications use physical models to adddetail and predict stability and loads. Test and evaluation applications use stability and load predictions to select maneuvers, instrumentation, and test conditions. Training applications use real time models to drive instrument displays, visual displaysand motion platforms. Simulation Based Acquisition combines manufacturing, operational, and economic models to predict life-cycle costs. In order to assure consistency between the models used to support these diverse applications it is desired to derivethese specialized models from a "Primary" comprehensive model. This will provide traceability and facilitate Verification, Validation and Accreditation (VV&A) for these models. ART has developed FLIGHTLAB, a simulation productivity tool that supportscomprehensive modeling and analysis, selective fidelity modeling, and code-generation to separate a model from the development environment and link it to a user's application. In this SBIR, ART proposes to demonstrate the feasibility of using FLIGHTLAB toderive a broad range of specialized rotorcraft models from FLIGHTLAB comprehensive models to support Army applications. The Phase I activity will focus on the development and testing of a rotor
