GAS TURBINE ENGINE WITH FAN CLEARANCE CONTROL |
| 摘要 |
A fan section for use in a gas turbine engine has a fan rotor with a plurality of blades and an outer fan housing surrounding the plurality of blades. A tip clearance is defined between a radially outer tip of the blades and a radially inner surface of the fan housing. A fan drive shaft drives the rotor. A drive input drives the fan drive shaft. A shifting mechanism shifts a location of the blades relative to the drive input, thereby controlling the tip clearance. A gas turbine engine is also disclosed. |
