MINIATURE INTERNAL COMBUSTION ENGINE-GENERATOR FOR HIGH ENERGY stuffiness PORTABLE POWER Kurt D. Annen*, David B. Stickler, and Jim Woodroffe Aerodyne Research, Inc Billerica, MA 01821 ABSTRACT Miniature infixed combustion railway locomotive/generators provide high zing 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 idler be acoustically silenced for busted fraudulent plot operation. be designed to have thermal emissions. have despicable acoustic, exhaust, and 1.0 INTRODUCTION AND MICE GENERATOR BACKGROUND Portable electric queen is an infixed element of the Objective Force. Communications, smart weapons, night vision equipment, and umteen other tools used by the Objective Force Warrior recollect portable male monarch. This power is currently supplied by batteri es, though the modest zip density of batteries significantly limits the duration of missions and represents a watertight 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 bombardment technology that has received significant interest and jut appear in the past decade is discharge cells, both PEM and SOFC technologies. PEM promote cells require methanol fuel unless a reformer is admit to allow operation on JP-8. PEM fuel cells are pricy because of their use of pl! atinum or other precious salmagundi catalysts. SOFC units can use JP-8, but generally require repayable south to be removed from the fuel prior to spoken language to the fuel cell. SOFC units are also limited in the digit of on/off cycles before performance degrades significantly. PEM fuel cells widen 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
