Compact Auxiliary Power System for Amphibious Combat Vehicle Navy SBIR FY2015.1 Sol No.: Navy SBIR FY2015.1 Topic No.: N151-004 Topic Title: Compact Auxiliary Power System for Amphibious Combat Vehicle Proposal No.: N151-004-0167 Firm: Great Lakes Sound & Vibration, Inc. 47140 N Main St. Houghton, Michigan 49931-9755 Contact: Greg Kangas Phone: (906) 482-7535 Abstract: The GLSV team will deliver a durable, compact, quiet, lightweight APU for powering on-board equipment when the main engine is off, providing silent watch capability for the ACV, and for subsystems operation during at-sea recovery. GLSV has assembled an exceptional team for this project and will integrate an advanced 2-stroke spark ignition engine for the power plant. This engine utilizes a patented technology that offers a high power density, compact size, the ability to utilize heavy fuels, and eliminates problems with cold weather starting that are typical of standard 2-stroke engines. The engine will be coupled to a ruggedized high output alternator that offers the best efficiency and is the coolest running alternator in the high output market. GLSV has been involved in several under armor APU noise and vibration reduction efforts . As the lead integrator, GLSV brings a unique skill set that will result in an improved integration approach that will design noise and vibration performance into the base APU architecture right from the start of the development cycle. This will result in a quiet APU that will also meet the packaging, power generation, and thermal management requirements. Benefits: The GLSV team will deliver a durable, compact, quiet, lightweight APU that will address the following Marine Corps priorities: light and compact, ability to package within a very tight space claim, high power density, low noise levels, high efficiency, and affordability. GLSV's solution is based on proven, maturing technologies and components to mitigate technical risk and assure the ability for near-term transition to the fleet. GLSV's APU is very durable, can utilize heavy fuels, and is based on a 2-stroke spark ignition engine that offers very high power density with increased reliability in cold weather over traditional diesel engines.
