Avartek, Scandinavia’s leading drone manufacturer, has been promoting recently its Avartek Boxer gas electric hybrid drone which is a gasoline powered UAS that provides its flight energy by transforming it into electric through its on-board power generator creating longer flight times while carrying heavy payloads. For example, it is capable of flying a 5kg load for 2 hours. The Boxer was first demonstrated a year ago.
The company website states, “Instead of carrying heavy batteries the Avartek Boxer Hybrid is designed around a liquid cooled mini generator power plant that transforms gasoline into electrical power. Currently the Boxer generator is capable of delivering 4 kW of energy.
This quadruples the flight mission lengths and provides easy on field operations due to the lack of battery management and charging problems. The Boxer design is fully custom. The airframe was designed by Avartek in Solidworks and all parts are manufactured in Finland.”
It goes on to say, “Only motors, escs, the flight controller and other electronics are out sourced. The whole copter is designed around the hybrid generator’s capabilities of producing 10x more energy than similar weight in LiPo batteries. 4 kg of gasoline provides 2 hours of flight time at MTOW 25kg, while a typical LiPo battery in this size of a drone of 11kg would only provide 30 minutes. 4 kg of gasoline (5 litres) equals 40 kg of LiPo batteries. On field operations greatly benefit from the very quick duty cycle of hybrid drone by offering easy refills instead of on battery management and recharging arrangements.”
