Planed speed advantage with wing deployed will be 10-15 kmh.Īdjustable wing in closed, non-active position, with air streams ideally connected with wing contours and without any turbulencesĪdjustable rear wing in active - deployed position. As it is a downforce shedding device, it acts against what most engineers are seeking, which is more downforce. The overall effect on straight-line speed is a bit like an F-duct, but much more powerful. This condition of separated flow is called a “ stall” and it is accompanied by a large drop in both downforce and drag on the car. This creates a situation where the two elements of the wing stop acting in harmony and the airflow around the wing separates from the surface of the wing decreasing its effectiveness and improving the straight-line speed of the car. DRS opening is increased by 20mm, boosting its potential power by around 25 percent.). The flap will be able to pivot around a point near the trailing edge (20 millimeters of it), away and upward from the main plane up to a maximum distance of 50mm (85mm from 2019 aero rules change) into a more horizontal position, and open up the slot gap ( For 2019 there was some minor rules change which involve wings. While the main plane remains fixed, the rules allow a driver to press a button on his steering wheel and some kind of actuator will lift the front, leading edge of the flap. Here, I will explain what a driver-adjustable rear wing is, how it works, and how it will be used.Īs for the mechanics of moveable wings, the adjustments that can be made are related to the two elements of the rear wing: the main plane and the flap which gap is adjusted in more favorable ( downforce wise) way closed for most of the lap, providing the car with the full downforce efficiency. The system will be disabled by driver manually, or the first time the driver uses the brakes after the system has been activated.” It will only be enabled if the driver is less than one second behind another at any of the pre-determined positions around each circuit. “The driver may only activate the adjustable bodywork in the race when he has been notified via the control electronics that it is enabled. That’s why the teams voted to remove adjustable front wings and try a new initiative with the rear wings with the intention of generating better overtaking opportunities. Instead it was used as a device to optimize car balance as the tires degraded and the fuel load reduced. The moveable front flap was brought in to try and assist with overtaking too, but in practice it didn’t really make a difference. It was a boring end to a spectacular season.Īfter the FIA World Motor Sport Council announced a new package of aerodynamic rules for 2011, the powers-that-be are hoping for more overtaking after driver-adjustable front wing of 2010 is gone ( a concept that never really delivered what was expected of it), replaced by a driver-adjustable - but FIA regulated - rear wing and bringing back KERS. Contenders Fernando Alonso and Mark Webber, who were first and second in the title race, chose the wrong strategy and found themselves stuck behind Renault's Vitaly Petrov with no way to overtake. The only time it cannot be used under any circumstances is two laps after the start or safety car restart and in wet conditions.Īlthough 2010's Championship proved to be one of the more thrilling with four drivers in the hunt for the World title heading into the final race in Abu Dhabi, it finished like a boring procession. The intention is to decrease drag for the chasing car and improve the chances of overtaking. New FIA "moveable bodywork" technical regulations for 2011 have allowed adjustment of the rear wing from the cockpit at any time in practice and qualifying, but only when a driver is less than one second behind another car at a pre-determined point on the track during a race.
