Abstract

The anterior and posterior grilles have a center (2) and a blade group that extends from the center to a ring (6), where the center of the anterior grille (1) includes a convex internal surface with ribs (11). The ribs extend to the internal surface of the center in prolongation of blades (3) of the group. The blades are separated from each other in a region near the center such that the blades are separated from the center. The blades are recessed in the center and on the ring, where the blades include a cross section in the form of an airplane wing.
