Front End Analysis of Soldier Individual Power Systems

摘要

The 1991 Army Science Board (ASB) Summer Study on 'The Soldier as a System'identified power as a major barrier to maximizing the soldier's warfighting capabilities. Individual Power was identified as an essential component of the Soldier System concept. The Front End Analysis (FEA) of power, conducted 1 May 1991 to 15 March 1992, delineates the requirements/constraints for achieving the power levels needed by dismounted soldier. The FEA drew upon the achievements and advances in power technology from the Army, other services, allies, and industry to evaluate state-of-the-art technologies and integrate them into a system with synergistic improvement in combat effectiveness. The FEA covers primary nonrechargeable and secondary rechargeable batteries, fuel cells, internal combustion engines, Stirling cycle engines, vapor and liquid cycle engines, and radioactive isotope power sources. Several other technologies were examined, but were judged not suited for further development. They are discussed in the FEA appendices. The operating and performance parameters of each technology were evaluated using a computerized parametric model. The model results indicate that primary battery-driven systems satisfied the short duration (8 hours), low energy mission and fuel-driven system satisfy longer duration, higher energy missions.
