is required (such as during takeoff ) the plane uses both the engine and the motor to drive the propeller. Once at cruising height, however, the motor can continue to assist the engine to help save fuel or be switched into “generator mode” and for it to recharge the batteries while the plane is in fl ight. According to the University of Cambridge, this is the fi rst time this has been achieved. A module designed by the engineering department at Cambridge is used to control electrical current to and from the lithium-polymer cell batteries, 16 of which are housed in compartments in the wings. There are many other similar eff orts, including those by
NASA, Airbus and a number of startup companies, and that are moving in similar directions.
MORE TO COME The move towards electrically-powered aircraft is still years away from having commercially-viable products, but we should see many novel UAVs, small GA and experimental aircraft emerging on the scene. It’s coming sooner than many might think. If aerospace fi rms are able to adapt technologies from the automotive and electronics markets in regards to power generation, power storage, and newer materials, the hybrid business jet cannot be that far away. It could then be followed by a hybrid regional jet. We might need to wait a bit longer for an “Airbus A380, powered by the Energizer bunny,” but who knows? All it takes is a few unpredictable research breakthroughs in nanotechnology, better solar cells and a few lighter aircraft materials.
