Abstract : Based on the historical development and the actual status of requirements, the trends of essential parameters are analyzed, physical and technical possibilities are assessed and a prognosis is offered. Increasing demands for secondary power for subsystems and more powerful engines have led to stronger secondary power components, thus creating a mass problem. Energy losses add a thermal problem. Complexity rises rapidly with the number of inputs and outputs. All of this, together with such aspects as redundancy, reliability, safety, maintainability and life cycle cost, composes today's auxiliary power system. The future system, in response to high performance requirements and budgetary and personnel restrictions, should aim at less complexity and more efficiency.
