To enable this capability, modeling and simulation tools that have the ability to be reconfigured to meet UAS design and development needs are required. Bihrle Applied Research Inc proposes the development of the Wake Interaction Determination for Simulation (WInDSim). The WInDSim concept leverages technology from previous SBIR efforts and COTS software, developed by BAR and its consultant, to create a comprehensive tool to model the effects of air wake disturbances on an air vehicle. The WInDSim will be an externally hosted simulation enhancement tool that uses state-of-the-art unsteady CFD-based wake models and advance aerodynamic prediction algorithms to compute wake-induced aerodynamic increments. The proposed Phase I effort examines the feasibility of the WInDSim concept by investigating several wake induced aerodynamic prediction methods and comparing results with measured data collected during previous research. In addition, a demonstration of the WInDSim concept will be performed. With the feasibility of the tool demonstrated, a Phase I optional effort defines software specifications and detailed designs. Benefits: The WInDSim will provide the ability to enhance the flight fidelity of wake interaction scenarios for existing simulation architectures without substantial code modifications. The reconfigurable nature of the software tool allows countless applications of tank-receiver combinations. The conceptual design of the WInDSim allows for application beyond wake interaction aerodynamics such as effects due to adverse weather and ship-wake. Such applications, when applied to military and civil pilot-in-the-loop flight simulators, expand training capabilities and improve safety. Return
