11769:RDS Abstract of the Disclosure An adjustable louver blade assembly including a number of horizontally extending, movable louver blades is described. Each of the blades is formed in a generally hollow airfoil shaped cross section having a leading edge and a trailing edge. Trips for inducing turbulent flow of the boundary layer are embossed on the blade surfaces and air flow seal strips can be secured to the trailing edge of each blade. Reinforcing spacer ribbons are frictionally secured within each blade to rigidize the blade. The pivotal axis of each blade is located so that the axis is forward of the center of aerodynamic force exerted on the blade for all attitudes of the blade between a closed position and a position about 60° from the closed position. Blade pivot axis spacing is such that in the fully closed position, the trailing edge of a blade contacts the adjacent blade along its leading edge. A control rod is connected to each of the louver blades so that all of the blades can be simultaneously swung to any attitude between fully open and fully closed. Each of the blades has chevron shaped slits with inwardly bent tabs near the trailing and leading edges of the blade to guide water on the surface of the blade into the hollow blade. Water is discharged from exit ports at the blade end into open vertical channels in the side frames which conduct water to hollow corner conduits for discharge. The frame that houses the louver blade assembly has a wall trap along the top to conduct water flowing down the outside of a supporting wall to the open channels at the side of the louver so that the water does not drip from the frame onto the louver blades, and thus be blown through the louver.
