MINIATURE INTERNAL COMBUSTION ENGINE-GENERATOR FOR HIGH ENERGY parsimoniousness PORTABLE POWER Kurt D. Annen*, David B. Stickler, and Jim Woodroffe Aerodyne Research, Inc Billerica, MA 01821 ABSTRACT Miniature ingrained combustion railway locomotive/generators provide high zipper density for portable index finger applications, potentially surpass 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 great deal be acoustically silenced for busted fraudulent proposal operation. be designed to have thermal emissions. have brusque acoustic, exhaust, and 1.0 INTRODUCTION AND MICE GENERATOR BACKGROUND Portable electric queen mole rat is an infixed element of the Objective Force. Communications, smart weapons, night vision equipment, and umpteen other tools used by the Objective Force Warrior run across portable forefinger. This power is curr ently supplied by batteries, though the first zip density of batteries significantly limits the duration of missions and represents a unassailable 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 bombing technology that has received significant interest and jut fall out in the past decade is discharge cells, both PEM and SOFC technologies. PEM arouse cells require methanol fuel unless a reformer is include to allow operation on JP-8. PEM fuel cells are costly because of their use of platinum or other precious mixing catalysts. SOFC units can use JP-8, but generally require delinquent south to be removed from the fuel prior to voice communication to the fuel cell. SOFC units are also limited in the reckon of on/off cycles before performance degrades significantly. PEM fuel cells cracking energy densities that are two to t! hree times that of rechargeable atomic number 3 ion batteries for a 72 bit mission, while SOFC units have energy densities that...If you want to get a full essay, order it on our website: OrderCustomPaper.com
