What does wicker bill mean?

The Gurney flap (or wickerbill) is a small tab projecting from the trailing edge of a wing. Typically it is set at a right angle to the pressure-side surface of the airfoil and projects 1% to 2% of the wing chord.

What is a wicker in Nascar?

With the addition of the wicker — an angled metal strip attached to the top end of the spoiler to increase drag — teams also have the options of changing gears without being penalized, provided that change occurs before qualifying.

What is a wing gurney?

A gurney flap is a small lip placed at the trailing edge of a wing, used to dramatically sharpen the exit angle of the airflow, thereby creating more downforce without the downside of drag that a car would have from a steeper wing angle. It’s named after ex-Formula 1 driver and team owner Dan Gurney.

Is a wicker bill worth it?

A wicker bill or larger rear spoiler will increase drag and lower your top speed. The advantage is it will increase your rear downforce at speed if it’s designed for it.

How tall should a Gurney flap be?

For the Gurney flap to be effective, it should be mounted at the trailing edge perpendicular to the chord line of airfoil or wing. The flap height must be of the order of local boundary layer thickness or typically 1% to 4% of the wing chord lengtht.

What is a flap F1?

Gurney flaps have been a part of Formula 1 for decades – invented by American driver Dan Gurney for his own racing operations.
