초록

A fluid delivery system in a gas turbine engine includes an electric motor, a first fluid pump system and a second fluid pump system. The electric motor operates at a variable speed. The first pump system includes a first pump driven by the motor to deliver a first fluid to the gas turbine engine. The second pump system includes a second pump driven by the motor to deliver a second fluid to the gas turbine engine, the second pump having a variable displacement.
