Ultra High Efficiency Blower System for Engine and Vehicle Applications

The objective of this program is to define, develop and demonstrate the best methods for moving air for different vehicle systems. The work will begin with an evaluation of all traditional air moving devices and find possible ways to improve efficiency and performance. Air movement technologies, to be evaluated include axial fans and blowers, radial fans, mix-flow blowers, and centrifugal (squirrel cage) blowers. Advantages and disadvantages of each type of air moving device will be examined.A clear understanding of how any air movement device fits into the system will be developed. If the air movement device does not operate at its peak efficiency, the system as a whole does not operate as efficiently as it could. It is paramount that each component within a system be understood from the system's perspective. Work will include the design and development of multiple air movement devices by a mathematical development process integrated with CFD analysis. Solid models of the finalized designs will be used to create working rapid prototype fans and blowers. Each prototype then will be performance tested. This will provide the measurable real world benefit of each design improvement. One or more of the prototype air moving devices will then be incorporated into other ongoing programs. The air moving device will be a part of an advanced fully controllable thermal management system. The system will be integrated into a vehicle platform yet to be determined, possible applications include the Humvee and FMTV. This vehicle will be fully tested to provide a comparison of the benefits of the advanced thermal system.
