Identify this (style of) spoiler.

[St. Anger]

At a complete loss here, any idea if there is someone manufacturing spoilers of this style that I can search for on google/ebay?



If not, another option would be just to make one - where would you go about looking for an adjustable hinge type mechanism to make it either follow the line of the boot or stick up like in the picture?

Over to you guys, the combined wisdom of PH has yet to fail me!

Thanks in advanced!

Try 'ducktail'

The little supports are splitter brackets and are height adjustable (to change the angle of the spoiler).

IIRC someone is currently making those for GT40 replicas so maybe check that out, I guess there made of plastic or aluminum, didn't the TVR sagaris use similar?

also, the adjustable screw mechanism is also used on front splitters.

Already had a search for "Adjustable Ducktail" on both ebay and google to no avail unfortunately.

eBay even autocorrected it to "Cocktail" for me.

The splitter bits look ideal, fantastic shout. Should be fairly easy to fabricate up something with them.. No?

Isn't that a Gurney flap?

No, that's a very small 90' flap added on the trailing edge of (usually front) wing aerofoil designs.

ETA - The black strip you can see on this wing on Senna's MP4/8 is a Gurney flap.

Well this is always described as a Gurney flap. Not arguing, just saying....

Quite wrongly.

Looks like they just use hardware store hinges to fix them. It doesn't need an airtight seal underneath, which would be really difficult to do because of the curved boot lid.

It is a gurney flap. They're normally on the trailing egde of a wing but it's still a GF when it mounted on the boot.

Gurney flap must be 90 degrees, otherwise it isn't a Gurney flap. That TVR spoiler isn't, surely.

In theory they should be set at 90 degrees on the pressure side but the OP is more likely to get what he's after if he searches for Gurney Flap rather than spoiler.

It might well be known as a Gurney flap-style spoiler, that's a bit more correct! But what's indicated on the McLaren and in the diagram there is an actual Gurney flap. The aerodynamic principle will work in a similar way putting one straight on the body, though.
