Abstract
A pre-exit thrust reverser includes an upper reverser door pivotally mounted to a frame and having an upper trailing edge, a lower reverser door pivotally mounted to the frame and having a lower trailing edge and an exhaust duct fixedly mounted to the frame. The upper trailing edge is configured to extend aft of the lower trailing edge when the thrust reverser assumes a deployed state.
Claims18
A pre-exit thrust reverser, comprising:
- an upper reverser door pivotally mounted to a frame on an upper side of a central axis extending through the pre-exit thrust reverser and having an upper trailing edge;
- a lower reverser door pivotally mounted to the frame on a lower side of the central axis and having a lower trailing edge;
- and
- an exhaust duct fixedly mounted to the frame,
- wherein the upper trailing edge is configured to extend aft of the lower trailing edge when the pre-exit thrust reverser assumes a deployed state and
- wherein the upper reverser door has an upper door length and the lower reverser door has a lower door length, the upper door length being greater than the lower door length.

A pre-exit thrust reverser for a turbofan engine, comprising:
- an upper reverser door pivotally mounted to a frame on an upper side of a central axis extending through the pre-exit thrust reverser and a lower reverser door pivotally mounted to the frame on a lower side of the central axis, the upper reverser door having an upper door length and an upper trailing edge and the lower reverser door having a lower door length and a lower trailing edge;
- and
- an exhaust duct fixedly mounted to the frame, wherein the upper door length is greater than the lower door length and wherein the upper trailing edge is configured to extend aft of the lower trailing edge when the pre-exit thrust reverser assumes a deployed state.
A gas turbine engine, comprising
- a core engine;
- a nacelle surrounding the core engine;
- a fan operably connected to the core engine and configured to drive air along a flow path in a bypass duct between the nacelle and an outer casing of the core engine;
- a mixing section where exhaust from the core engine is mixed with air from the bypass duct and
- a thrust reverser downstream of the mixing section, wherein the thrust reverser comprises
- an upper reverser door pivotally mounted to a frame on an upper side of a central axis extending through the pre-exit thrust reverser and having an upper trailing edge;
- a lower reverser door pivotally mounted to the frame on a lower side of the central axis and having a lower trailing edge;
- and
- an exhaust duct fixedly mounted to the frame,
- wherein the upper trailing edge is configured to extend aft of the lower trailing edge when the thrust reverser assumes a deployed state and
- wherein the upper reverser door has an upper door length and the lower reverser door has a lower door length, the upper door length being greater than the lower door length.
