By combining gas and electric motors, Airstier, a German company, is hoping for faster flying and lengthier flight times. This new innovative concept can stay airborne for up to 60 minutes and carry up to 5kg in weight. You can help make the “yeair!” design a reality by contributing on KickStarter.
While combustion-powered drones can be more difficult to control as effectively as battery-powered UAVs, airstier claims to have tackled this limitation by developing a “electrically powered alternate/hub shaft”. This shaft is “coupled to the combustor to relate accelerations and delay values”, which the firm says enables its flight to be as stable as an all-electric drone.
The additional power of the combustion engines should also let the yeair! drone operate in stronger winds than is possible using consumer drones today. yeair!’s dual engines also allow for one engine to take over and keep the craft airborne in the event of engine failure.
