Patent ID: 8870264

Claim:
A pair of symmetrical, revolving, dihedral, semi-permeable aerodynamic devices, comprising one left such device ( 1 ), featuring a central cavity section ( 13 ), leading edge profiling ( 8 ), trailing edge profiling ( 12 ), top end profiling ( 10 ), lower end profiling of the leading edge ( 15 ), dihedral angle ( 9 ), central cavity section relief opening ( 11 ), variable permeability holes ( 14 ), and is based on a base ( 4 ), which can rotate about an axis of rotation ( 16 ), via a control mechanism ( 5 ), which is supported through the support module ( 6 ), which is capable to move independently of, or in tandem with, one right such device ( 2 ), (which is symmetrical to the left device ( 1 )), and which can rotate about an axis of rotation ( 17 ), and is connected via a support structure ( 7 ), the aerodynamic devices depending on their size and form are fitted on the vehicle in any position determined by the aerodynamic effectiveness of the devices, the devices ( 1 ), ( 2 ) can rotate clock-wise as well as counter-clock-wise, independently, or in tandem, the dihedral angle ( 9 ), effectively splits each aerodynamic device into an upper and a lower section, and forms the central cavity section ( 13 ), which resembles a base-ball glove, which has a concave (inner) and a convex (outer) surface, due to the contouring of the inner and outer surfaces.
