Claim:
1. A multi-surface blocker door system, comprising: a first blocker door rotatably coupled to an inner fixed surface about a forward end of the first blocker door, wherein the first blocker door is configured to rotate about the forward end of the first blocker door such that an aft end of the first blocker door rotates radially outward, with respect to a longitudinal axis of the inner fixed surface, and wherein, when deployed, the first blocker door is configured to block a first portion of bypass air in a fan air duct, the first blocker door operatively coupled to a first drive mechanism, wherein the first drive mechanism is configured to deploy the first blocker door, wherein the first blocker door is located forward of an aft end of a translating sleeve; and a second blocker door rotatably coupled to the translating sleeve about a forward end of the second blocker door, wherein the second blocker door is configured to rotate about the forward end of the second blocker door such that an aft end of the second blocker door rotates radially inward, with respect to the longitudinal axis of the inner fixed surface, and wherein, when deployed, the second blocker door is configured to block a second portion of bypass air in the fan air duct, the second blocker door operatively coupled to a second drive mechanism, wherein the second drive mechanism is configured to deploy the second blocker door; wherein when the first blocker door and the second blocker door are deployed, a portion of the fan air duct defined radially, with respect to the longitudinal axis of the inner fixed surface, between the aft end of the first blocker door and the aft end of the second blocker door is unobstructed by the first blocker door and the second blocker door.
