The achievement of a single-power generation distribution and utilization system on future high-performance aircraft will yield many benefits in the form of improved maintainability, reliability, and logistics. It will also reduce aircraft weight and the number of skill catagories required in maintenance training programs. Current aircraft have two parallel and nearly equal-sized secondary power systems (electrical and hydraulic). Of the two, only electrical has the potential for powering all significant functions on the aircraft from radio to landing gear. However, even though electrical power generation and distribution has always been competitive with hydraulic, electrical actuators (utilization) have been heavy and slow. For this reason, hydraulics have for many years monopolized all actuation applications in which power and/or frequency response requirements were moderately high.
