We examine power and energy systems for propulsion, guidance, navigation, control, communication and other primary, secondary and auxiliary systems of unmanned aerial vehicles (UAVs). The major objective is to develop a scalable and modular design concept in energy harvesting, energy storage and energy management. Different energy sources, including solar energy, are used to power light-weight long-endurance low-, medium- and high-altitude UAVs, satellites and other platforms. Fixed wing UAVs must ensure flight specifications, mission effectiveness, speed, altitude, endurance, etc. Agile and maneuverable rotary wing UAVs are also enabled by alternative energy sources. We study high-efficiency energy systems, low-power electronics and energy management for propulsion systems, control surfaces actuators, sensors and other key components.
