Abstract
A fuel system for a gas turbine engine includes a fuel pump to provide fuel flow during engine operation and a transmission system that includes an output shaft coupled to drive the fuel pump, and an input shaft driven through a mechanical link to a shaft of the gas turbine engine. The output shaft drives the fuel pump at a variable speed that is independent of a rotational speed of the input shaft.
