Variable speed and displacement electric fluid delivery system for a gas turbine engine
摘要：
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.
摘要（中）：

燃气涡轮发动机中的流体输送系统包括电动机，第一流体泵系统和第二流体泵系统。 电动机以可变速度运行。 第一泵系统包括由马达驱动以将第一流体输送到燃气涡轮发动机的第一泵。 第二泵系统包括由马达驱动以将第二流体输送到燃气涡轮发动机的第二泵，第二泵具有可变排量。
