Miniature Aerial vehicles:
Propulsion and Energy Sources

< Most miniature UAVs are powered by electrical motors, which limit their endurance to 1 2 hours, enabled by the power density provided by the batteries carried on board. Although internal combustion (piston) engines could provide a good alternative, their noise signature, weight and reliability are not suitable for MAV applications. Current MAVs are using specially designed lithium primary batteries, while new high density zinc-air cells have also been introduced, to offer up to 33% higher density power compared to lithium batteries. Zinc-Air batteries are designed specifically for mini-UAV applications. Developmental items have already been tested with NASA on a micro-UAV, flying a 58 minute mission. Other designs are underway for micro UAVs such as IAI Mosquito, as part of an Israel's MOD R&D program. Future applications of DARPA's "palm power" power cells could also be applied to MAVs, offering extended range and endurance.
