Abstract
An example thrust reverser blocker door includes a blocker door that is movable from a stowed position to a deployed position. Flow moves through an area of a bypass flowpath when the blocker door is in the stowed position. The blocker door blocks no less than about 70% and no more than about 85% of flow through this area when the blocker door is in the deployed position, wherein the area does not extend circumferentially past the blocker door.
Claims17
A thrust reverser blocker door, comprising:
- a blocker door moveable from a stowed position to a deployed position, wherein flow moves through an area of a bypass flowpath when the blocker door is in the stowed position, and the blocker door blocks between no less than 70% and no more than about 85% of flow through this area when the blocker door is in the deployed position, wherein the area does not extend circumferentially past the blocker door.
A gas turbine engine thrust reverser system, comprising:
- a nacelle that establishes a radially outer boundary of a flowpath;
- a core engine that establishes a radially inner boundary of the flowpath;
- and
- an array of blocker doors moveable from a deployed position to a stowed position, the array of blocker door in the deployed position blocking more flow through the flowpath than the blocker door in the stowed position, wherein the blocker doors in the deployed position permit from no less than 15% to no more than about 30% of flow through the flowpath that the blocker doors in the stowed position permit.
1 more element
A gas turbine engine thrust reversing method, comprising:
- (a) redirecting no less than about 70% to no more than about 85% of flow from a bypass flowpath through a cascade arrangement;
- and
- (b) moving the remaining flow through an bypass flowpath exhaust.
