Improved Turbo/Superchargers for UAS/UGS Application

Baker Engineering Inc. (BEI) proposes an advanced, electrically-assisted turbocharger to meet the needs identified in this solicitation. BEI"s solution provides a lightweight, durable, self-lubricated turbocharger that will set new standards in performance on heavy fuel engines in the 50-150 Hp class. An electrically-assisted turbocharger offers supercharger characteristics to a turbocharged engine application. The turbo retains thermal efficiency benefits through conventional use of exhaust gas energy for operation, while improving engine low end power with turbo assisted operation. Integration of emerging technologies pertaining to bearing design, lubrication methods, and variable turbine geometry further improve engine performance and turbo reliability. Alternate materials and hardware design options offer weight savings capabilities to the turbo hardware. BEI will expand upon previous electrically-assisted turbo development efforts, where the concept has been demonstrated on a new engine technology called the Opposed-piston Turbo Diesel Engine. Phase I efforts will focus on designing an electrically-assisted turbocharger for this specific application, with emphasis on drive interface, cooling/lubrication, weight reduction, durability and required electronics. During Phase II, the electrically-assisted turbocharger concept will be developed into a working prototype, incorporating data and results from the Phase I effort.
