Here it is another 3D model, but this is different: it's mine
just joking, i'm serious now. This is the first model i've ever done in 3D (i used Google Sketchup), so forgive me as it's not that good. I wanted to show it to you some weeks ago, before the championship had started, unfortunately my computer broke down...
Anyway, i hope you like it, I wait for your comments, advices, etc
(note: the model is not meant to participate to any sort of virtual challenge, thought I tried to follow the 2012 F1 regulations. ...and I have to confess that i copied the “Coanda exhaust” from Sauber
)
as you can see the car is pretty radical. I did not use cfd programs but in my mind it should work this way: the front wing works together with the sidepods as it keeps the airflow as straight as possible, feeding the “vacuum” in between the lateral crash structures and the lowered sidepods. The sidepods themselves are generally similar to those used by Sauber and Red Bull, designed to direct the exhaust's gases to the diffuser.
The nosecone, i fear, is illegal as you see it now, but this is just to show you the concept: it partially sacrifices the “high nose” concept, but it generates a bit of downforce and, moreover, accelerates and carries a lot of air up to the engine air intakes (they work together with the rear wing) and to the rear.
So, this car is supposed to have a high top speed, tons of downforce at the front and enough downforce at the rear not to drift all the time...
top wiew
please tell me if this nosecone could be legal. It is a triplane: the first two elements are part of the monocoque, while the third one is inspired to that Mclaren's wing recently abandoned that they used in order to separate airflows... do you remember? The point is that I want to use it to pick up the flows in the best way possible, directing them in between the other two elements in order to be slightly accelerated. As i said before the whole thing is also designed to achieve downforce (=similar to Force India's last year concept).
see better here:
Front Wing. The lower elements are devided in 2: the external part is supposed to have the maximum surface useful to create the biggest possible low pressure area; it should also decrease the drag of the wheels (in fact i didn't need to deal with deviating sideways the air, as everybody do, thanks to the design of the sidepods, thus i could concentrate on downforce and drag).
The internal part directs the air to the upper sidepods.
The secondary elements on the top are just meant to help the lowers, to clean the streams and to play with Venturi effect together with the wing's pylons.
lowered sidepods to feed more the rear of the car and to decrease the lift generated by the Sauber's solution
a close view on the rear. Starting from the low-left corner you see a strange floor shape: it is a channel that directs streams sideways, decreasing a bit the rear wheel drag (it is supposed to have a second function too, but i'm not confident... i think i'm going to remove it).
In the center of the photo you see the “Coanda exhaust” (in this area I'd really need a cfd program); it is designed to split the hot flow into 2 secondary flows: the first one is directed to the diffuser, the second should go into the cut, decreasing the pressure around the wheel and “feeding” the floor.
Sorry for the rest... the diffuser area isn't refined at all.
here it is another huge problem I had: the air intakes for the engine and for cooling. That's the impossible part to design without cfd. My idea was to use the air suked by the engine to accelerate more air into the secondary intakes: these ones are supposed to accelerate even more the air and direct it to the rear elements (=more downforce but less angine power).
So, can i use the opposite concept to increase the power output, as a sort of supercharging?
sorry for the long post and for the possible english errors
... but, to be honest, my idea was different and simply crazy (that's why i'm gonna get rid of it, or al least redesign it)
) ....
Help me!
