REDUCTION IN JET FLAP INTERACTION NOISE WITH GEARED TURBINE ENGINE

摘要

A turbine engine system mounted on an aircraft wing includes a gas turbine engine having a spool, a turbine coupled with the spool, a fan coupled to be rotated about an axis through the spool, and a gear assembly coupled between the fan and spool such that rotation of the spool results in rotation of the fan at a different speed than the spool. The gas turbine engine is operable to discharge a jet plume that interacts with a flap of the aircraft wing. The gas turbine engine defines a design fan pressure ratio of 1.25-1.50 to control sound resulting from the jet plume that interacts with the flap.
