| 摘要 | Systems and methods for driving an oil cooling fan (36) of a gas turbine engine (10) during different modes of operation of the gas turbine engine (10) are described. A system may include a coupling device (40) configured to: transmit motive power from a power turbine shaft (22) of the gas turbine engine (10) to the oil cooling fan (36) during a first mode of operation where the power turbine shaft (22) is turning, and to decouple the oil cooling fan (36) from the power turbine shaft (22) during a second mode of operation where the power turbine shaft (22) is prevented from turning. An alternate source (42) of motive power may be configured to drive the oil cooling fan (36) during the second mode of operation. | ||

| 主权项 | 1. A system for driving an oil cooling fan of a gas turbine engine, the system comprising: a coupling device configured to: transmit motive power from a power turbine shaft driven by a low pressure turbine of the gas turbine engine to the oil cooling fan during a first mode of operation where the power turbine shaft is turning, and todecouple the oil cooling fan from the power turbine shaft during a second mode of operation where the power turbine shaft is prevented from turning; and an alternate source of motive power configured to drive the oil cooling fan during the second mode of operation, the alternate source of motive power including a high pressure turbine of the gas turbine engine. | ||
