Abstract : The objective of the present concept study was to critically review and assess innovative advanced technology concepts of heating and cooling which can be applied to ECUs to support the Global Reach-Global Power strategy of today's USAF mission while protecting the environment. Nine innovative technologies were reviewed and of these, six were rejected as unsuitable to Air Force ECU needs at the present time of the remaining three, Stirling cycle heat pump technology was selected as the most suited to Air Force advanced needs. Hybrid Stirling systems such as the 'pulse-tube', have been identified as being capable to meet all major performance criteria such as appreciable reductions in both weight and volume, increased energy efficiency, and the elimination of occupationally hazardous or environmentally suspect refrigerants. Gains in these areas within follow-on R&D efforts will provide forward deployed forces a more capable, less logistically taxing ECU system.
