...Fuller placed the wood boy face down on an improvised operating table and made his incision with a sharp, small-bladed knife. Ultraviolet examination had shown that Golden Boy had already undergone an operation, and Fuller cut along the old, virtually imperceptible scar.* He cut carefully through a top layer of paint (probably put on 700 or 800 years ago), then through a layer of gesso, a layer of lacquer, one of bronze and finally of the statue's original gold. After 30 minutes he lifted out a 2-in.-by-4-in. rectangular section...
...through water. They always failed. As the air flowed over the wing, it broke into curling eddies that dragged at the plane and drank up the engine's power. In theory, the scientists knew that this "burble" effect could be prevented by sucking into the wing a thin layer of air, and with it the incipient eddies. The remaining air would glide past the whole wing in smooth "laminar flow" (see diagram...
This long-discussed system remained largely a dream for 50 years. But last week Northrop Aircraft, Inc. recorded the results of seven years of experimentation with "low drag boundary layer control." After elaborate tests with models in wind tunnels, Northrop engineers fitted the wing "of an F94 jet fighter with a "glove" containing twelve slots running lengthwise along the wing. A suction pump driven from the main engine pulled air into the slots and pushed it out astern with the rest of the jet's gases, adding a little to the thrust. The reduction of drag was extraordinary, even...
Vice President Edgar Schmued of Northrop thinks that B.L.C. (Boundary Layer Control) will be the next great advance in airplane design. It will be most useful in long-range airplanes, since Northrop's figures indicate that the range of any B.L.C. airplane should be almost double that of a "turbulent" plane of the same weight...
...powerful machines are slashing through the hill, cutting a 360-ft.-deep, 2,200-ft.-long scar -the biggest man-made road gash since the Panama Canal. All told, the machines will move 8,500,000 cu. yd. of earth, enough to cover Manhattan Island with a 4.5-in. layer...
