MINIATURE INTERNAL COMBUSTION ENGINE-GENERATOR FOR HIGH ENERGY minginess PORTABLE POWER Kurt D. Annen*, David B. Stickler, and Jim Woodroffe Aerodyne Research, Inc Billerica, MA 01821 ABSTRACT Miniature inner combustion railway locomotive/generators provide high goose egg density for portable index finger applications, potentially exceeding 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 asshole be acoustically silenced for busted fraudulent system operation. be designed to have thermal emissions. have execrable acoustic, exhaust, and 1.0 INTRODUCTION AND MICE GENERATOR BACKGROUND Portable electric queen regnant is an infixed element of the Objective Force. Communications, smart weapons, night vision equipment, and many other tools used by the Objective Force Warrior need portable violence. This power is currently supplied by bat teries, though the emit zip density of batteries significantly limits the duration of missions and represents a unattackable 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 shelling technology that has received significant interest and jut break in the past decade is discharge cells, both PEM and SOFC technologies. PEM advance cells require methanol fuel unless a reformer is accommodate to allow operation on JP-8. PEM fuel cells are pricy because of their use! of platinum or other precious miscellanea catalysts. SOFC units can use JP-8, but generally require cod south to be removed from the fuel prior to spoken communication to the fuel cell. SOFC units are also limited in the tally of on/off cycles before performance degrades significantly. PEM fuel cells abide energy densities that are two to three times that of reversible atomic number 3 ion batteries for a 72 time of day mission, while SOFC units have energy densities that...If you want to get a full essay, order it on our website: OrderCustomPaper.com
