초록

An elongated airfoil is perforated in such a way as to cause boundary layer air at the airfoil surface to be drawn into the airfoil, and then evacuated.

청구항
▼

In an elongated airfoil having an upper wall, a lower wall, a forwardly presented and convex front wall, and a trailing edge portion, the combination comprising (a) first partition means in the airfoil extending generally lengthwise thereof, to form with said walls a front chamber and a rear chamber, (b) the front chamber including a section spaced generally lengthwise of the airfoil, (c) certain perforations or slots at and in the forwardly presented front wall associated with said section whereby air is forced into said section to flow therein lengthwi...
