Cabin pressure thrust recovery outflow valve with single door

摘要

A single valve door thrust recovery outflow valve is provided that does not rely on a relatively large and expensive actuator to move it, and does not create unwanted drag during aircraft cruise operations. The valve includes a valve frame, a valve door, and an aerodynamic flap. The valve door is rotationally coupled to the valve frame, is adapted to receive a drive torque, and is configured, upon receipt of the drive torque, to rotate between a closed position, a full-open position, and a plurality of partial-open positions between the closed position and the full-open position. The aerodynamic flap is coupled to the valve door. When the valve door is in the closed position and in numerous partial-open positions, the aerodynamic flap makes the thrust recovery outflow valve aerodynamically clean.

主权项

1. An aircraft cabin pressure control system thrust recovery outflow valve, comprising:
a valve frame configured to be mounted on an aircraft exterior skin, the valve frame including an inner surface, an outer surface, a forward seat, and an aft seat, the inner surface defining a flow passage through the valve frame; a single valve door rotationally coupled to the valve frame, and including a leading edge, a trailing edge, and two side edges, the single valve door adapted to receive a drive torque and configured, upon receipt of the drive torque, to rotate between a closed position, a full-open position, and a plurality of partial-open positions between the closed position and the full-open position; and an aerodynamic flap including a first end and a second end, the first end coupled to the single valve door, the second end biased toward the trailing edge of the single valve door, wherein the second end engages the valve frame when the single valve door is in the closed position and in a plurality of open positions.
