A secondary wing 5, 6 is provided below a main wing of a flying object (such as a light aircraft, a motorized paraglider having a propeller 2 and a harness 1 attached to a primary wing (not shown), an unmotorised paraglider, a microlight aircraft, an unmanned aircraft or a model aircraft). The secondary wing is adapted to pivot and may be controllable independently of the primary wing to vary its angle of attack and thereby increase or decrease the wing loading. The secondary wing may be made from foamed materials, polystyrene, or honeycomb composite or ribbed structure, and may comprise two independently movable elements. The secondary wing may be provided with movable flaps. |
