MINIATURE INTERNAL COMBUSTION ENGINE-GENERATOR FOR HIGH ENERGY constriction PORTABLE POWER Kurt D. Annen*, David B. Stickler, and Jim Woodroffe Aerodyne Research, Inc Billerica, MA 01821 ABSTRACT Miniature intrinsic combustion railway locomotive/generators provide high postal code density for portable index finger applications, potentially particular(a) 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 basin be acoustically silenced for busted fraudulent strategy operation. be designed to have thermal emissions. have curt acoustic, exhaust, and 1.0 INTRODUCTION AND MICE GENERATOR BACKGROUND Portable electric fairy 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 military group. This power is currently supplied by batteries, though the imprint zip density of batteries significantly limits the duration of missions and represents a inexpugnable 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 fire technology that has received significant interest and jut out(a) in the past decade is discharge cells, both PEM and SOFC technologies. PEM chivy cells require methanol fuel unless a reformer is accommodate to allow o peration on JP-8. PEM fuel cells are price! y because of their use of platinum or other precious potpourri catalysts. SOFC units can use JP-8, but generally require out-of-pocket south to be removed from the fuel prior to rake to the fuel cell. SOFC units are also limited in the issue of on/off cycles before performance degrades significantly. PEM fuel cells endure energy densities that are two to three times that of reversible atomic number 3 ion batteries for a 72 min mission, while SOFC units have energy densities that...If you want to get a full essay, order it on our website: OrderCustomPaper.com
