The team has designed and tested the major components of the motor, and shown through detailed computations that the coupled components can work as a whole to generate one megawatt of power, at a weight and size competitive with current small aero-engines.įor all-electric applications, the team envisions the motor could be paired with a source of electricity such as a battery or a fuel cell. To meet this need, a team of MIT engineers is now creating a 1-megawatt motor that could be a key stepping stone toward electrifying larger aircraft. These would be propelled by hybrid or turbo-electric propulsion systems where an electrical machine is coupled with a gas turbine aero-engine. To electrify larger, heavier jets, such as commercial airliners, megawatt-scale motors are required. Their electric motors generate hundreds of kilowatts of power. To date, however, only small all-electric planes have gotten off the ground. Aviation’s huge carbon footprint could shrink significantly with electrification.
