Innovative Onboard Power and Cooling Solutions

"Problem: Provide lightweight on board capability installed in heavy aircraft to generate 1000KVA electricity and 800lbsm/min of pressurized air at 50psia. Fuel cell technology is insufficiently mature for this purpose. System options: 1). Single turboshaft engine/generator(s) combined with load compressor(s) sized to requirements. 2). Multiple turbo shaft engines (2 or more) driving synchronized generators and load compressors sized to requirements. 3). Multiple light weight (2 or more) turbo shaftengines with supplemented airflow at altitude (supercharged) driving synchronized generators and load compressors sized to requirements. 4). Integrated single shaft engine generator(s) as represented by SAE Paper 981281coupled with single or multiple loadcompressor(s). Each option includes: 1). Analysis and selection of optimum generators matched to available shaft power. 2). Develop methodologies for mating generator(s) and load compressor(s) to selected engines. 3). System integration andpackaging i.e. enclosures, ducting, control system, fire suppression etc. and provision for delivering electrical power and pressurized air to the aircraft systems. 4). Weight reduction by modifying aircraft system components. Best value candidate(s)will be identified during first month. Research activity at SDII is underway. Best value candidate(s) concepts refined and developed during balance of Phase I. Anticipated Benefits: The tech
