Hi all!

Like Hades does on his own tread, I've started a fantasy F1 shape within the 2011 regulations. The car is still WIP but for sure, there will be template for it. I didn't manage to give you a template for the 2009 cars I did, so it's a bit fair to give you template for this one!

I have got NO knowledge on aerodynamic, but for fun, I will explain why I shaped my fantasy car this way.

[B*******] begins now

This car will run the Cosworth Engine

Within the rules of 2011, basically, RedBull's sharkfin style has been forbidden and also the roll-over bar a la Mercedes, so I decided to just have a classis engine cover with the mandatory bodywork on the engine cover.
New rules prevent any aperture on the underfloor behind the driver cockpit, in order to prevent the double diffuser. Height of the diffuser has been reduced too from 200mm to 175mm. So basically, the diffuser is less efficient, but still, is the part which give the most downforce ( with the underfloor of course ) with not a lof of drag. So I opted for a high nose, in order to put more air under the car and maximaze the diffuser effect ( U-shaped nose a la RedBull has been used in order to put the most clean air as possible under the nose ) .

The mirrors cannot be in the sidepod fin anymore since China 2010, and they cannot be fit too close to the cockpit ( like Ferrari and Redbull did last year for instance )

On this second shot, you can see that the sidepod rear end is really tight and really low, in order to make the diffuser working best with the lower and upper rear wing. Also, in a slight way, it lowered the center of gravity which have been highered by the raised nose.

The apertures from the sidepod end are very tiny, so hot air is evacuated by an aperture on the engine cover, like did RedBull. A little wing is placed behind the aperture to guide the airflow upwards in order to reduced the drag caused by the rear wing.

Rear wing feature the movable device. There is not a lot of precision on the rules of how it can be implemented to the car, so you can use the movable device like a mini-winglet which will have the effect to have better airflow through the upperface of the rear wing ( like did the BAR in 2004 in Australia which was immediatly asked to reduce the size by the FIA because it was too efficient ).

The front of the car is very complex ( I'm sure in real life it will NEVER work!

).
The main wing looks a lot like Toyota's and Lotus's ones, shaped in a way to reduce vortices on the inner part of the wing, without losing a lot of downforce. Like all cars in 2010, front fins are shaped in a way to guide airflow away of the front wheels.

The upper front wings ( I don't know how are they called, but I talked about the wings who lies with the front fins ), add extra downforce to the car and not only put the airflow above the front wheels but also on the external side of the wheels. Why I choose that? Because of Massa in Barcelona, after he damaged his front wing by hitting an HRT I believe, he gained 0,5s on the next laps. His wing where oriented like mine! But honestly I think he gained 0,5s just because I wasn't behind a car anymore.

The little appendice near the center line of the car seperate the which go into the radiator to the flow which go around and above the sidepod. It also permit to feed air to a special part of a car...

This is a weird shape for a splitter!

Basically, new rules prevent the use of double diffuser. But I think I've found a way to use Legal Double Diffuser. Last year, an aperture was made near the rear wheel centerline on the underfloor in order to make the ddd working. Now, bodywork which can be seen from underneath must form one continous surface from around the rear end of the cockpit to the end of the diffuser.

But my opening is made a lot earlier. There is a slot under the splitter which will be reduced along the length of the car in order to accelerate the airflow going through it. I tried to put the maximum of clean air flow through this slot to maximize the effect of my ddd

The exit of the diffuser. It's a simple shaped double decked diffuser. Gurney trim's has been added on top of the main diffuser in order to create a low pressure area which will help airflow exiting upwards and reducing the drag.

As I said earlier, all I said is certainly a Non-sense

but it's just for fun!
