摘要： A gas turbine engine includes a shaft defining an axis of rotation. An outer turbine rotor directly drives the shaft and includes an outer set of blades. An inner turbine rotor has an inner set of blades interspersed with the outer set of blades. The inner turbine rotor is configured to rotate in an opposite direction about the axis of rotation from the outer turbine rotor. A splitter gear system couples the inner turbine rotor to the shaft and is configured to rotate the inner set of blades at a faster speed than the outer set of blades.

摘要： A high-bypass ratio geared turbomachine comprises a compressor section (24) of a high-bypass ratio geared turbomachine. The compressor section (24) provides at least a low-pressure compressor (44) and a high-pressure compressor (52), wherein a rotor of the low-pressure compressor (44) rotates together with a rotor of a fan (42).

摘要： An exemplary system for delivering a turbomachine fluid to a supplied area is a pump configured to draw fluid from both a first container and a second container when operating in both a positive g-force environment and a negative g-force environment. The fluid from the first container in a positive g-force environment is a mixture of air and oil, and the fluid from the first container in a negative g-force environment is primarily oil.
