ABSTRACT:
The pickup truck tailgate mounted drag reducing aerodynamic stabilizer or aerostabilizer acts as a turning vane(s) to direct air out over the tailgate thereby reducing drag, provides a stabilizing downward force on the aft end of the pickup truck during forward high speed operation of the pickup truck, and all of this is accomplished with an assembly that is out of the way when the tailgate is opened for carrying long boards or the like. The tailgate aerostabilizer is a very simple, low cost, and easy to install device that can, in its preferred embodiment, be molded from one piece from weather resisting plastics or the like. An optional feature is a built in air braking device that can have as forces for actuation, in addition to aerodynamic forces, a torque spring, powered actuator, or other artificial force generator.
