DIS instead of DRS?

[tomazy]

The overtaking problem of modern F1 cars is that they can't follow each other through the fast corners, becouse thay lose too much front downforce. So why don't we have a sistem that increases front downforce in corners if the car is less than 1s behind aka Downforce Increase System (DIS).

With this sistem, the car behind would make an old fashion pass with slipstreaming, and when he will go out of slipstream, he would not just drive around the car in front like with DRS. DRS does not provide us with wheel to wheel action, DIS just might?

What are your thoughts on that?

The loss of front downforce is a product of the turbulent wake of the leading car. I would think any aerodynamic surface you put in this turbulent air would perform poorly due to a lack of laminair flow acting upon it. If you had a DIS as you describe I'm guessing it would act to increase the surface area or AoA of the front wing, neither of which does much for the problem of running in turbulent air.

A blown wing of some type would improve downforce. Getting sufficient air flow through the system would be challenging however. It would be heavy too.

There is too much to get wrong with this setup even if they some how find extra downforce in the wake. The driver may not be able to practise with extra downforce in practise since he would need a car in front of him and what happens if there is a DIS failure the driver might understeer away from the track of the DIS device might get stuck hence ruin the top speed on straight.

Basically anything that changes downforce levels during lateral acceleration has a high chance of going wrong.

I think it's a good idea. Of course F1 had adjustable front wings in 2009, but the teams ended up using it for reasons other than intended.
Adding the <1second gap restriction might actually force it to be used as intended.

These are all possible problems with rear wing DRS too. When DRS was introduced there was all sorts of doom and gloom about cars crashing when it fails, but in reality we've had very very few problems.

Personally I think the solution can be much simpler.
All we really need is a reduced reliance of front end aerodynamic downforce and perhaps more mechanical front-end grip.

The less front end aerodynamic grip there is, the less there is to lose from running behind another car.

The adjustable front wing was removed because it was useless at the job it was intended for, the topic of adjustable front wings comes up time and time again on the forum, it may have been worth having a look around at existing threads first.


Turbulence is unpredictable and chaotic in its nature, changing wing angle of attack doesn't seem to be sufficient enough in reclaiming lost downforce.
