Fleet-Wide Variability for an Integrated Flight and Propulsion System Navy SBIR FY2005.2 Sol No.: Navy SBIR FY2005.2 Topic No.: N05-117 Topic Title: Fleet-Wide Variability for an Integrated Flight and Propulsion System Proposal No.: N052-117-0416 Firm: SC Solutions 1261 Oakmead Pkwy Sunnyvale, California 94085-4040 Contact: Robert Kosut Phone: (408) 617-4526 Web Site: www.scsolutions.com Abstract: This Small Business Innovations Research Phase I project proposes a product development effort aimed at establishing procedures and software tools for quantifying the impact of component dynamic performance variability across a fleet of Integrated Flight and Propulsion Control systems (IFPC). We propose a set of innovative tools to guarantee dynamic performance, for full life, across a fleet of aircraft. The innovative feature of the proposed methods is that a few experiments or high-fidelity simulations are carried out on a small subset of a large number of propulsion controllers and the nearby controllers are validated or rejected using much simpler simulations. The performance criteria for variability analysis include thrust, stability margins, and failures. The evaluation will demonstrate the analytical feasibility assessment for a representative complex high bandwidth propulsion control problem. In Phase I, the developed techniques will be applied to a Short Takeoff and Vertical Landing (STOVL) example. Prototype validation algorithms will be developed in an industrial software environment. In Phase II, technology developed at SC Solutions and UCSD will be made into a prototype software product and will be demonstrated on a problem that can be scaled to a full-sized IFPC system. The potential for wide-ranging commercial applications is very significant since we will be developing the first-ever commercially available validation tool. Benefits: The proposed software product represents a dramatic enhancement over current status of tools for validation for control. Since the software tool features primitives for fleet-wide variability for propulsion control design validation for the first time, the potential commercial applications are great. The technology will have broad commercial and military utility. The potential product from this effort will be a software product for PC or workstation containing the computational tools for generating from a large set of controllers, a small subset of controllers to be tested by experiments or high-fidelity simulation that are compatible with typical workstation control design capabilities. Such a tool will be very beneficial to aerospace companies involved in the control design of high-performance systems which need to model complex flight and propulsion interactions. Return
