Title:
AERODYNAMIC BODY PROVIDED WITH SURFACE CAVITIES
Document Type and Number:
WIPO Patent Application WO/2003/013957
Kind Code:
A1
Abstract:
An airfoil is provided with a surface cavity (1) having an aperture (2), towards the external surface of the airfoil, and defined by a front edge (7) and rear edge (6) positioned transversally to the direction of movement of the profile, in which the front edge (7) is reentrant with respect to the rear edge (6) by a distance (H). The area (5) located upstream of the front edge (7) slopes gradually downwards from the outer surface of the profile towards the cavity (1) in order to divert part of the flow of the fluid F, which skims the outer surface, into the cavity (1).
