description A variable gear ratio gas turbine engine system includes a planetary gear set, a gas turbine engine, an electric machine, and a controller. The gas turbine engine includes at least a low-pressure compressor, a high-pressure compressor, a combustor, a high-pressure turbine, and a low-pressure turbine. The low-pressure turbine is coupled to the low-pressure compressor via the planetary gear set. The electric machine is coupled to the planetary gear set and its rotational speed is used, at least in part, to vary the gear ratio of the planetary gear set. The controller is in operable communication with the gas turbine engine and the electric machine and is configured to control: the low-pressure turbine to rotate at a substantially constant speed and the rotational speed of the electric machine to thereby vary the gear ratio of the planetary gear set, whereby the speed at which the low-pressure compressor rotates is also varied.
