Tyrrell Boomerang Wing

[Ted68]

They didn't race it, so it must not have worked. But would a wing like this create more down force or less drag or what?

I could imagine the concept was getting more aerodynamic downforce during yaw conditions.

Damn, we need cars looking like this again... no hold barred development!

such an wing has increased wing span, and works better under yaw, i think it would increase drag by alot, as in the centre i believe you will get an bubble. On the other hand, the air will not likely go up on the wing in a straight line, so drag is a guess but im sure it gives more yaw performance

Great pics! I had never seen that wing before.

In that era (~1984) the rules allowed extra "ear-wings" outboard and slightly forward of the main wing--

My guess is the boomerang rear wing was an attempt to exploit the extra width of the ear-wings without the compromise of extra end plates and corresponding end effects.

As I recall from its debut back in 83 was the design was to gain more wing area than the rules allowed. Toleman came up with the idea that as long as you had a 'rear' wing of the maximum allowed width, then another wing could be as wide as the bodywork rules allowed. Maurice Phillipe came up with idea, but the concept ran in practice and soon dropped for a conventional single rear wing. I don't think yaw was a concept considered for aero back then.

Rules back then stipulated maximum width for a wing placed behind the rear axle.

Toleman installed a mid-wing just forward of the rear axle, complementing the standard one:



Others extended the rear wing endplates forward of the vertical plane passing by the rear axle, so they could have wing extensions outboard of these endplates:





This Tyrrell solution kept the width of the wing located behind the rear axle at maximum width, but its delta shape permited for it to be extended further. Notice that the endplates in that Tyrrell also are fully located in front of the axle. It was the most "colourful" solution, but also the least successful one.

Maybe they were looking for a center vortex resulting in downwash on the lower surface? – Just guessing .
