Abstract
A retrofit gas turbine engine includes a compressor, a combustor and a turbine. A tie shaft is connected to rotate by the turbine, and provide rotational drive into a gearbox. At least one fuel pump is connected to be driven by the gearbox. The at least one fuel pump delivers fuel downstream toward the combustor, and also has a return line. An added accessory turbine is positioned on the return line, and drives an added accessory which has been retrofit added to an existing gas turbine engine. A method is also disclosed.
