Energy conservation techniques: increasing the endurance of small UAVs

Energy conservation techniques: increasing the endurance of small UAVs
All small Unmanned Aircraft (UA) have severe limitations from a lack of endurance capability. This is a direct result of using battery technologies which are limited in their capacity, current capability, mass and energy density. The most widely used chemistry in small battery powered UAVs is Li-Po with its peak energy density of about 200 Wh/kg. Much research has been directed at finding alternative power sources, from Solar, Hydrogen Fuel Cells to Nuclear batteries. The latest contender is Li-S chemistries which appear to offer energy densities of up to 400 Wh/kg within the next 2 years. Li-S batteries claim to be safer in terms of damage tolerance and the lack of thermal runaway, which can be an issue with the current generation Li-Po batteries. This presentation will outline the alternatives and point towards the likely future direction of this technology. The author will also present other design strategies and design tools which help to promote the efficient use of power within these types of Unmanned Aircraft.

Abstract

All small Unmanned Aircraft (UA) have severe limitations from a lack of endurance capability. This is a direct result of using battery technologies which are limited in their capacity, current capability, mass and energy density. The most widely used chemistry in small battery powered UAVs is Li-Po with its peak energy density of about 200 Wh/kg. Much research has been directed at finding alternative power sources, from Solar, Hydrogen Fuel Cells to Nuclear batteries. The latest contender is Li-S chemistries which appear to offer energy densities of up to 400 Wh/kg within the next 2 years. Li-S batteries claim to be safer in terms of damage tolerance and the lack of thermal runaway, which can be an issue with the current generation Li-Po batteries. This presentation will outline the alternatives and point towards the likely future direction of this technology. The author will also present other design strategies and design tools which help to promote the efficient use of power within these types of Unmanned Aircraft.
