Abstract: A multi-airfoil element wing includes a central single-airfoil element and an outer dual-airfoil element positioned outboard of each side of the central single-airfoil element. The single-piece member defines aerodynamic surfaces of the central airfoil element and both of the outer dual-airfoil elements. The single-piece member includes a carbon fiber resin hollow body forming at least a portion of the central single-airfoil element and of both outer dual-airfoil elements.

Abstract: Multiple vertical panel strakes extend from a rear underbody of the automobile in a street configuration. Multiple vertical panel extensions include extension coupling elements designed to removably couple the vertical panel extensions to the plurality of vertical strakes in a track configuration. When the rear underbody aerodynamic diffuser is in the street configuration, the plurality of vertical panel extensions are uncoupled from the plurality of vertical panel strakes and the vertical panel strakes have an overall width that extends a vertical street distance. When the rear underbody aerodynamic diffuser is in the track configuration, the plurality of vertical panel extensions are removably coupled to the plurality of vertical panel strakes and the combined vertical panel strakes and vertical panel extensions have an overall width that extends a vertical track distance that is greater than the vertical street distance.

Abstract: The present invention provides a windshield frame utilizing composite technology. More particularly, the windshield frame preferably comprises a fiber reinforced plastic molded upper frame section bonded with a structural grade adhesive to a fiber reinforced plastic molded lower frame section. According to the invention, steel reinforcements and tapping plates are bonded on or molded into the frame sections to stabilize the structure and provide hardware attachment points. Continuous carbon fibers may also be molded in the frame sections in critical high stress areas. The strength of the bonding between the frame sections is enhanced by a tongue and groove geometry along the interface. In addition, dowel pins and bushings are used to mechanically tie the frame sections together near body side attachment points.
