wind-cutter

Century Dictionary and Cyclopedia

1. n. A construction or configuration for the front end of a high-speed vehicle, such as a railway-car or motor-vehicle, by which the resistance to motion by displacement of the air is lessened. Such wind-cutters are sections of conoids or inclined or warped surfaces presenting a sharp edge of entry into the air, or receiving the wind pressure on areas oblique to the direction of motion. Dirigible aërodromes have wind-cutting ends. The Engineer (London), 1901, p. 432.
2. n. In organ-building, the upper lip of the mouth of a flue-pipe, against which the, stream of air impinges when the pipe is sounded.
