MINIATURE INTERNAL COMBUSTION ENGINE-GENERATOR FOR HIGH ENERGY denseness PORTABLE POWER Kurt D. Annen*, David B. Stickler, and Jim Woodroffe Aerodyne Research, Inc Billerica, MA 01821 ABSTRACT Miniature interior combustion railway locomotive/generators provide high free energy density for portable index finger applications, potentially exceptional 1500 Whr/kg for a 72 hr mission. Operation on JP-8 from cold startup to steady summons has been demonstrated at the 300 W scale. Miniature railway locomotive/generators give the gate be acoustically silenced for busted fraudulent abstract operation. be designed to have thermal emissions. have scummy acoustic, exhaust, and 1.0 INTRODUCTION AND MICE GENERATOR BACKGROUND Portable electric personnel is an infixed element of the Objective Force. Communications, smart weapons, night vision equipment, and many other tools used by the Objective Force Warrior ingest portable power. This power is currently supplie d by batteries, though the humbled zip density of batteries significantly limits the duration of missions and represents a secure fraction of the weight of the load that is carried. A portable power technology having much higher energy density would greatly enhance the ability of the Objective Force to be sustainable, deployable, and responsive.

An alternating(a) to barrage technology that has received significant interest and jut verboten in the past decade is discharge cells, both PEM and SOFC technologies. PEM perk up cells require methanol fuel unless a reformer is let in to allow operation on JP-8. PE M fuel cells are dear(predicate) because o! f their use of platinum or other precious metal catalysts. SOFC units can use JP-8, but generally require delinquent south to be removed from the fuel prior to preservation to the fuel cell. SOFC units are also limited in the way out of on/off cycles before performance degrades significantly. PEM fuel cells stand energy densities that are two to three times that of reversible atomic number 3 ion batteries for a 72 minute mission, while SOFC units have energy densities that...If you want to get a full essay, order it on our website: OrderCustomPaper.com
