Abstract
A valve is provided for controlling a flow of a fluid between a first environment and a second environment. The valve includes a frame adapted to fit within a perimeter of an aperture in a divider separating the first environment from the second environment. The valve additionally includes a first gate movable within the frame to control a flow of the fluid through the aperture between the first environment and the second environment. The first gate includes a substantially aerodynamically clean surface substantially free from protrusions disrupting the flow of the fluid over the first gate surface. Additionally, the first gate includes a trailing edge having a baffle adapted to cover an aft edge of the frame when the first gate is positioned to have a small opening angle. The baffle includes a plurality of 3-D notches in a front side of the baffle. The valve further includes a second gate movable within the frame to control a flow of the fluid through the aperture between the first environment and the second environment. The second gate also includes a substantially aerodynamically clean surface substantially free from protrusions disrupting the flow of the fluid over the second gate surface. Additionally, the second gate includes a trailing edge comprising a plurality of 3-D notches in a front side of the trailing edge.
