Bargeboard

The nose of the Red Bull RB1 , the gray wing behind the wheel with the advertisement for Hangar-7, is a so-called bargeboard

A barge board ( German : air deflector ), also known as turning vanes known is an aerodynamic attachment, which especially in the single-seater - Formula racing occurs. Bargeboards are mounted on both sides at the transition from the nose to the cockpit of the car. The main purpose of these wings is to influence the airflow for more downforce .

Mode of action

Roughly speaking, a bargeboard stabilizes and forwards the air flow swirled by the front wing and the wheel suspension, the so-called dirty air . One task is to reduce the air resistance and to keep the swirling air away from the wings, which are responsible for the pressure of the car. Most of the time, the flow is directed directly to the side radiators of the car to actively help cool the engine components. More rarely, the current is diverted over the side pods to protect the fragile cooling from the strong winds and foreign objects such as loose pieces of rubber after graining , so-called marbles .

Vortex generator

Today barge boards are mainly used as so-called vortex generators to German vortex generators . The air is directed through complex channels in the car to the rear, where it flows into the diffuser of the car and uses the energy obtained from it.

history

A Benetton B193 ; The bargeboard is very clearly visible directly behind the rear wheel suspension

The bargeboard was first used in Formula 1 cars in the early 1990s, but they were kept even simpler. The 1993 Benetton B193 was one of the first vehicles to have bargeboards installed. In the following year, many other teams such as Williams , Ferrari , Jordan , Tyrrell or even the financially weak team Simtek already used such wings. McLaren only followed suit with the McLaren MP4 / 10 in 1995 , but already used such wings in 1993 in some races, namely in Donington , Monaco and Budapest , among others . In the 1999 Formula 1 World Championship , a Ferrari bargeboard almost led to the premature world championship title for Mika Häkkinen , as after the penultimate race in Malaysia the race winner and world championship candidate Eddie Irvine was disqualified for an illegal bargeboard. However, Ferrari protested and successfully demonstrated that the attachment was legal.

It was only after the turn of the millennium that these wings became increasingly complex and not all too rarely contained several smaller attachments. In 2009 the FIA began to regulate the construction and placement of bargeboards with new regulations.
