Research Projects: Research projects are focused on an improved understanding of human-in-the-loop simulation as well as the enabling technologies for the virtual flight test and virtual test track environments. General research topics include: Human motion perception measurement and modeling Human control behavior measurement and modeling Simulator motion drive algorithm (MDA) development and tuning  -The MDA filters the calculated vehicle motions to fit within the envelope of the simulator motion envelope High-fidelity real-time fixed and rotary wing aircraft models suitable for Handling Qualities evaluations Aircraft parameter estimation Current and Recently Completed Projects: Effect of simulator yaw motion on pilot’s control of helicopter yaw tasks Visual/motion phase detection threshold of human subjects An actuator state based adaptive motion drive algorithm Parameter estimation techniques for flight vehicles with invasive flight control systems The addition of a dynamic inflow and curved wake model to a real-time helicopter simulation. Potential Future Projects: Development of a high-fidelity motion drive algorithm for a large displacement driving simulator Experimental determination of optimal tuning parameters for fixed wing simulator motion drive algorithms Measurement and modeling of human motion perception thresholds Development of a human control model with internal noise sources Engineering level fidelity real-time fixed wing aircraft models
