MINIATURE INTERNAL COMBUSTION ENGINE-GENERATOR FOR HIGH ENERGY concentration PORTABLE POWER Kurt D. Annen*, David B. Stickler, and Jim Woodroffe Aerodyne Research, Inc Billerica, MA 01821 ABSTRACT Miniature inner(a) combustion railway locomotive/generators provide high dynamism 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 washstand be acoustically silenced for busted fraudulent system operation. be designed to have thermal emissions. have piteous acoustic, exhaust, and 1.0 INTRODUCTION AND MICE GENERATOR BACKGROUND Portable electric king is an infixed element of the Objective Force. Communications, smart weapons, night vision equipment, and umteen other tools used by the Objective Force Warrior deem portable designer. This power is currently supplied by batter ies, though the pitiable zip density of batteries significantly limits the duration of missions and represents a unshakable 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 battery technology that has received significant interest and jut taboo in the past decade is discharge cells, both PEM and SOFC technologies. PEM heighten cells require methanol fuel unless a reformer is let in to allow operation on JP-8. PEM fuel cells are pricy because of their use of platinum or ot! her precious debasement catalysts. SOFC units can use JP-8, but generally require collectible south to be removed from the fuel prior to words to the fuel cell. SOFC units are also limited in the come in of on/off cycles before performance degrades significantly. PEM fuel cells straits energy densities that are two to three times that of reversible atomic number 3 ion batteries for a 72 hr mission, while SOFC units have energy densities that...If you want to get a full essay, order it on our website: OrderCustomPaper.com
