1. An aircraft cabin pressure control system thrust recovery outflow valve, comprising:
- a frame configured to be mounted on an aircraft exterior skin;
a valve element rotationally coupled to the frame, the valve element coupled to receive an actuation drive force and responsive thereto to rotate to a position between a closed position and a plurality of open positions; and
a position sensor coupled to the frame and configured to directly sense rotation of the valve element and supply a position signal representative of valve element position.

Abstract
An aircraft cabin pressure control system outflow valve includes a frame, a valve element, and a position sensor. The frame is configured to be mounted on an aircraft exterior skin. The valve element is rotationally coupled to the frame, and is coupled to receive an actuation drive force. The valve element is responsive to the actuation drive force to rotate to a position between a closed position and a plurality of open positions. The position sensor is coupled to the frame and is configured to directly sense rotation of the valve element and supply a position signal representative of valve element position.

9. An aircraft cabin pressure control system thrust recovery outflow valve, comprising:
-
a frame configured to be mounted on an aircraft exterior skin; an actuator coupled to the frame and operable to supply an actuation drive force; a first door rotationally coupled to the frame and further coupled to receive the actuation drive force supplied by the actuator, the first door responsive to the actuation drive force to rotate to a position between a closed position and a plurality of open positions; a second door rotationally coupled to the frame and further coupled to the first door, the second door responsive to rotation of the first door to simultaneously rotate therewith to a position between a closed position and a plurality of open positions; and a first position sensor coupled to the frame and configured to directly sense rotation of the first door and supply a position signal representative of first door position; and a second position sensor coupled to the frame and configured to directly sense rotation of the second door and supply a position signal representative of second door position. - View Dependent Claims (10, 11, 12)
