We have developed a hybrid-electric propulsion system that is recharged by an internal combustion engine, and other methods to sustain battery charge levels and improve safety by guaranteeing that aircraft can land using remaining electrical energy if the engine fails. We are also researching fuel cells to potentially bridge the transition between battery-powered and internal combustion engine-powered UAVs.
