This week, I was pleased to attend and present at a workshop hosted by MITRE on the topic of expeditionary power and energy. MITRE is a non-profit organization that applies their deep technical capabilities to support the U.S. Department of Defense and other branches of the U.S. government. Topics addressed in the workshop covered every aspect of energy—from well to wheels, including biofuels, storage, transmission, conversion and usage. It is clear that an “all of the above” approach to energy is necessary to support our troops, just as it is to improve our environment and economy via better passenger and commercial vehicles.

Developing the Next-Generation Combat Engine

Improved fuel economy is important for many applications, but it is especially important for military vehicles. These vehicles are adding armor to protect against improvised explosive devices. They’re also adding expensive and heavy armament and communication technology. As the vehicle weight increases, so does the need for more powerful engines to maintain the same performance characteristics. And, these more powerful engines add weight.
 
One way to reduce this weight, however, is to use propulsion systems with high power density. A paper written by Charles Raffa, Ernest Schwarz and John Tasdemir of the U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC) emphasized that the “real need is for the complete propulsion system to be power dense”. This includes the engine, transmission, cooling system, air filtration system, intake and exhaust ducting, controls, accessories, batteries, fuel systems and final drives. A key way to increase the power density of the propulsion system: use a more efficient engine, since it can dramatically reduce the volume and weight of the fuel required for a given range.

Wednesday marks the start of GVSETS, a three-day event focused on the latest technologies for military ground vehicles. Introducing breakthrough innovations designed to aid and protect our troops, this year’s symposium features a presentation from Achates Power. The topic: how can the Achates Power opposed-piston engine improve the operational efficiency of military vehicles?
 
While opposed-piston engines have been used in aviation and combat vehicle applications and continue to be used in maritime applications, there are several factors that distinguish the Achates Power engine from previous opposed-piston engines. Continue reading
