A study was performed to define and evaluate secondary power systems for an advanced Army rotary-wing aircraft, using existing technology and two advanced technology levels. The basic aircraft mission, performance penalty parameters, and system components are defined. From a total of 162 candidate systems, 36 were selected for detailed comparisons. Evaluation parameters included incremental takeoff gross weight, system weight, volume, reliability, maintainability, availability, power APU that drives into the aircraft accessory gearbox with two electrical generators and two hydraulic pumps. Main engines are started pneumatically by bleed air from the APU. Cockpit cooling was an optional addition, and an air-cycle system was selected. (Author)
