IPC: F15D1/00
Filed: 2007-01-26
Abstract: A friction-drag reducing surface is provided to increase speed or save energy by reducing air friction at a wing and a body of an airplane and reducing air friction between a propeller and a rotor blade. A friction-drag reducing surface includes a plurality of spines(1), a head(2) of the spines, and a surface(3) to which the spines are attached. The spines are attached at the interval of 10 micrometers to the surface of an object to move in fluid such as air, water or the like, wherein lengths of the spines are about 15 micrometers. Therefore, the spines reduce the friction with the fluid by preventing the surface from being in directly contact with the fluid flowing around the spines. The spines can be obtained by mechanically cutting or etching the surface where a plurality of tips are raised above the surface independently. The friction-drag reducing surface can be obtained by attaching the spines to the surface.
