GEARED GAS TURBINE ENGINE INTEGRATED WITH A VARIABLE AREA FAN NOZZLE WITH REDUCED NOISE

摘要

A gas turbine engine includes a spool and a turbine coupled to drive the spool. A fan is coupled to be driven by the turbine through the spool. A gear assembly is coupled between the fan and the spool such that rotation of the spool drives the fan at a different speed than the spool. A fan nozzle is located downstream from the fan. The fan nozzle includes a variable area nozzle configured to change an exit area of the fan nozzle. An acoustic liner partially lines the fan nozzle.
