HIGH DOWN FORCE WINGS
#91
#92
Not exactly... Any airfoil (even a flat plate) has an "angle of attack" at which it will "stall" (create turbulent flow over the curved portion) which kills lift (or in this case, since we are dealing with an inverted wing with the camber on the bottom) it kills downforce. For most airfoils, that angle is somewhere between 12 and 15 degrees of angle.

Hey All
I dont want to take sides but we have tested these wings in a liquid flow bench as well as a wind tunnel in germany it cost us over 3 million dollars to test toy car wings. The test was done by none other than Daild Carlson who is an ex aeronautical engineer for Nasa. I say EX because he quit and then forgot everything he knew. He once owned 50% of Microsoft and is directly related to Elvis Presley !
the results are top secret so dont tell anyone !

What results are we supposed to keep secret? You never posted any.

Anyway, here is the latest .... Boeing, Airbus, and Mugen Seiki are developing new rear wing to increase downward airflow while reducing thermal wind flow signature. Hopefully the new design will increase top speed & downforce at the same time. It is known the Delta Phi Sigma of the angle of attack of the wing will transalate into fuel ecnomy as well. Such hybrid design will be nominated for 2008 noble prize in aeronautical technology.

You forgot to mention that they are also good for the environment. I've been told they reduce green house gases by 10% when run on Mugens and 50% on the Airbus A380.

The Himoto and Proline wings APPEAR to be designed correctly. The Jconcepts one is not. The slotted portion of the wing re-energizes the airflow, allowing it to remain attached on the rear portion which is at a much greater angle- the first part of the wing turns the airflow somewhat, so the AOA limit there is different. Sounds silly, but it is really how it works.
The Jconcepts wing is depending solely on reaction against the upper surface, like a regular parachute. The others SHOULD actually be generating lift (in reverse, so it is downforce) off the lower surface as well, although the way they are molded at the front leaves a bit to be desired... I'm not sure if the ridge along the front causes it to trip the boundary layer to help the airflow stay attached, or causes TOO MUCH turbulence and kills the lift. I'd have to see it in a wind tunnel to know for sure, but I suspect it may be the bad effect and not the good one. None of the manufacturers is putting much real thought into the aerodynamics of those wings!

Food for thought!! Hmmmm!!

when I was running K2 with stock kyosho wing (2 days a week almost every week) 3 yrs ago, I can feel a difference bwtn different wing mounting angles when jumping a long triple. With a higher wing angle, the front end stays up more than a flatter wing angle while in the air. The buggy feels more neutral and easier to drive with flatter wing angle.
so what kind of effect will a high down force wing do while the buggy is in the air? and on the ground? Thanks.
