Abstract

Sufficient energy provision for a high flight autonomy is one of the greater challenges for the unmanned aerial systems (UASs) to become efficient and economically profitable for various agricultural applications ranging from remote sensing to farm supply applications. This chapter presents the main architecture of different kinds of UASs and analyzes their power and energy demands and their suitability for alternative tasks. Focusing on different types of propulsion systems, it analyzes their performances and response to power demand variations. It also presents different types of energy storage components and the technologies employed for providing electric power in UASs, their capacity, main features and discuss the key factors affecting drone power demands and energy consumption. Finally, the chapter highlights the most promising future technologies implemented to improve drone endurance and provide a clean energy source presenting also some commercially available solutions.
