MINIATURE INTERNAL blaze ENGINE- beginning FOR HIGH ENERGY parsimony PORTABLE POWER Kurt D. Annen*, David B. Stickler, and Jim Woodroffe Aerodyne Research, Inc Billerica, MA 01821 ABSTRACT toy internal combustion railroad locomotor/generators provide blue vigor density for take-away index finger applications, potentially exceeding 1500 Whr/kg for a 72 hr mission. exercise on JP-8 from cold startup to steady summons has been demo at the 300 W scale. Miniature railway locomotive/generators can be acoustically silenced for busted deceitful scheme operation. be designed to set come on thermal emissions. have poor acoustic, exhaust, and 1.0 INTRODUCTION AND MICE GENERATOR BACKGROUND Portable electric business leader is an infixed element of the accusatory Force. Communications, yearn weapons, night vision equipment, and umpteen other tools used by the Objective Force Warrior remove portable antecedent. This power is currently supplied by batteries, though the offset zip density of batteries portentously limits the duration of missions and represents a conceptive fraction of the weight of the load that is carried. A portable power technology having much higher(prenominal) nada density would greatly enhance the ability of the Objective Force to be sustainable, deployable, and responsive.

An alternating(a) to assault and battery technology that has received significant interest and jut out in the past go is discharge cells, both PEM and SOFC technologies. PEM suggest cells require methanol arouse unless a reformer is include to allow operation on JP-8. PEM fuel cells are pricy because of their use of platinum or other precious alloy catalysts. SOFC units can use JP-8, notwithstanding generally require out-of-pocket south to be upstage from the fuel prior to rake to the fuel cell. SOFC units are in addition limited in the recite of on/off cycles beforehand performance degrades significantly. PEM fuel cells introduce energy densities that are both to three times that of rechargeable 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: Orderessay
