DRS – Drag Reduction System
Drag Reduction System concept has been set up to make races more progress by create effortless overtaking. DRS will be permitted to be used at any time in practice and Qualification but carry on safety intimidation in mind it will bounded with FIA rules and regulations when it comes to actual race day.
How DRS will work in Formula 1?
The drivers will now have a button accessible on steering wheel which will change the angle of rear wing while the car is going at high speeds. This choice will only be accessible when a car is within a certain distance of the leading car.
How and when DRS will be used in races?
Closeness to the car in front will be sensed before the straight on which the wing may be opened. If the car at the back is less than one second the driver will be told that his system is “armed”, but, he may only use it when he reaches a particular point on the following straight line. This point is likely to be 600-800 meters before the breaking point for the following curve.
Currently entertainingly the television broadcasters will be sent a signal each time a system is armed and this will be displayed to the audience. Based on simulation stats’ it appears that the dissimilarity between a car using the wing(DRS) and one not using it is likely to be in the region of 10-12km/h at the end of the straight.
Physics behind the fast moving car
When an object ride through a fluid (air in this case), it counters a resistance offered by the fluid the value of which differ with
(1) Speed of the ride object
(2) Shape of object
(3) Viscosity of the fluid.
When a Formula 1 car ride through the road, the air puts up a resistance against the car the consequence of which is to stop it? This can result in increased power compulsion from the engine which of course we don’t want to happen.
So we are left with a choice to try out to decrease this resistive force known as “aerodynamic drag”. The fundamental theory in easy language can be found in any basic fluid mechanics textbook. Race cars use wings and other aerodynamic bits & construction of car body to reduce this drag. These wings reduce this resistive force by either reducing the area that faces the stream of air coming in or making the flow take a certain path along it which imposes a uniform pressure rather than concentrated pressure and the drag somewhat decrease.
F1 rear wing is designed to do this job. When it is laid parallel to the direction of velocity, it reduces the drag but also causes loss of downforce (which we also generate using these wings for ease of handling, the turns taken at speeds like 150 km/h are only possible due to downforce). So we conclude two things here:
1. When wing angle is less (i.e parallel to air stream), the drag reduces, downforce reduces resulting in increased speed
2. When wing angle is more (i.e perpendicular to air stream), the drag increases but downforce increases resulting in less speed but increased stability
