Window Ailerons

Weather permitting, I prefer driving with my windows down. There are several valid reasons for this preference, such as the added safety of hearing the traffic around you, or , (as it is with me), the ability to rest my arm on the bottom edge of the open window.

If you have ever spent a great deal of time at highway speeds with your window down, you must be aware of the deafening noise this creates, along with the constant wind buffeting that is wont to re-direct your cigarette butt back into the car from time to time.

As a paratrooper (aka the cigarette butt being flicked out the window), I was used to plunging into 130 mph turbulence, as I exited the aircraft; however I was astonished to find myself standing on a platform outside of the aircraft without a lick of wind sheer when I jumped the C-17 Globemaster, toward the end of my paratrooping days.

This strange phenomenon is due to a pocket of low-pressure created by aerodynamic contouring to the fore of the paratrooper exit.

With a properly contoured aileron that extends from the leading edge of the car window, such a pocket could be created over the open window, making for a quieter, smoother and possibly more aerodynamic ride (with windows down), and of course a much safer cigarette flick.
