The new system has an electric engine which is connected to the conventional engine, a high-efficiency lithium battery and an electronic system that draws energy from the battery and adapts it to the needs of the plane. It also has a battery charger which operates during the flight. “We maximize the capacity of the battery in generating movement with the electric engine, and we have found that we can also use the system as a hybrid for light aircraft: the pilot can activate it when she wants, adding up to 40 horsepower for take-offs or whatever is needed,” said Daniel Cristobal, from AXTER Aerospace and an alumnus of the UC3M. This way, it could be used as if it were an electric turbo to increase the power of the aircraft in certain maneuvers.
This system, which is being marketed and patented internationally, can be installed in all light aircraft, new or already operating. Also, it might eventually be applied to other types of aircraft, such as gyroplanes, gliders, drones and other unmanned aerial vehicles. In addition to saving lives and avoiding financial losses resulting from accidents, its architecture reduces the airplane’s operating and maintenance costs, lowers fuel consumption and reduces the emission of greenhouse gases and noise pollution.
