PIVOT DOOR THRUST REVERSER

摘要

A geared turbofan engine includes a fan, a low pressure turbine, a geared architecture, and a nacelle. The fan and low pressure turbine are capable of rotation about an axial centerline of the gas turbine engine. The geared architecture connects the fan to be driven by the low pressure turbine. The nacelle is disposed circumferentially around the fan and defines a portion of a bypass flow duct. The nacelle includes a thrust reverser assembly with one or more doors that pivot to block at least a portion of the bypass flow duct in a deployed position.

1. A geared turbofan engine with a bypass ratio that is greater than six, the engine comprising:
a first spool capable of rotation about an axial centerline of the gas turbine engine; a second spool capable of rotation about the axial centerline; a fan capable of rotation about the axial centerline; a geared architecture, wherein the fan is coupled to the low pressure compressor and the low pressure turbine through the geared architecture; and a nacelle arranged circumferentially around the axial centerline and defining a portion of a bypass flow duct, the nacelle comprising:
a thrust reverser assembly with one or more doors that pivot to block at least a portion of the bypass flow duct in a deployed position, wherein the thrust reverser has an effective flow area that is greater than a bypass flow duct exit area of the bypass flow duct.
