초록

Blades, including helicopter rotor blades, gas turbine engine fan blades, air moving machinery fan blades, and the like, have an air inlet near the hub of the blade, which may be on the pressure side of the blade and/or near the leading edge or trailing edge nearer the tip of the blades, with an air plenum between the air inlet and the slots, whereby air is forced into the inlet, through the plenum and out of the slots into the flow adjacent the blades. The slots may be through the suction surface of the blade, typically near the boundary layer separatio...

청구항

[We claim:] [1.]a hub, a leading edge, a tip, a root, a pressure surface and a suction surface;an air inlet extending through the pressure surface of said blade near said hub;a plurality of slots extending through the suction surface of said blade closer to said tip than to said hub near the boundary layer separation point of said suction surface; anda plenum within said blade extending from said air inlet to said slots. whereby as said blade rotates, air is forced into said air inlet and driven by centrifugal force along said plenum to exit from said sl...
