In this proposed Phase II SBIR project for the Office of Naval Research, Orbital Traction, of Houston, Texas, will develop, fabricate, test, and demonstrate a prototype of a novel variable speed cooling fan for use on military ground vehicles. This innovative device will improve fuel efficiency by 1 to 6%, depending upon the particular vehicle and duty cycle, through optimization of vehicle cooling fan speed. This variable speed cooling fan drive, also referred to as a Controlled Velocity Accessory Drive or CVAD, will be extremely compact, highly efficient, and readily adaptable for other military and commercial vehicle applications.
