Why is it called a Gurney flap?

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.

What is a gurney flap on a spoiler?

A Gurney flap is a fitting which can enhance the performance of an airfoil like a wing or so-called spoiler on a vehicle. It can improve the ratio between lift and drag to increase efficiency and performance.

Who invented gurney flap?

manager Dan Gurney
3 Gurney flap. Gurney flaps were invented by well-known race car driver and team manager Dan Gurney in 1971 for use on his team’s cars to increase traction for better handling. The device was subsequently introduced to the aeronautics community by Liebeck in 1976 [63].

What sport uses a gurney?

Common applications occur in auto racing, helicopter horizontal stabilizers, and aircraft where high lift is essential, such as banner-towing airplanes. It is named for its inventor and developer, American race car driver Dan Gurney.

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 Wickerbill spoiler?

The wicker bill is an extra high-angled lip added to a spoiler. This addition heightens the aerodynamic properties of the spoiler. The flap that points up increases traction, and the car can make tighter turns.

How do Wickerbills work?

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.

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. The flap is simply a small vertical piece attached to the trailing edge of a wing. Although small, the Gurney flap changes the airflow characteristics around the wing quite dramatically.
