Method, system and computer program product for the optimization of power system architectures at the aircraft level during pre-design

In an aircraft power system architecture, power requirements stem from functional top-level aircraft requirements and from the interrelationship among many systems. Thus, to balance power in the overall aircraft power system architecture or at least a portion of the power system architecture at the aircraft level, these interrelationships are considered. A method, system and computer program product are provided for the management of power system architectures at the aircraft level during pre-design. The designer can specify top-level aircraft parameters, and power values in all the systems of the aircraft at varying levels of complexity can be displayed.
