2009 design concepts

[greenpower dude reloaded]

Oh and one more thing..

Without having read the rules (shame on me) whats the possibility of of the teams using the front wing as it now extends as far as the front wheels a bit so say some sort of shield just to keep the air off the best part of the front edge?

To give some of you an idea as to how lossy wheels can be. In the racing series i race in one team made one modification to they're car between races by covering three of they're wheels (most of us don't have the man power to get everything done in time for a race) and reported a 4 mph increase in speed which mean't that they could reach 31mph instead of 27.

So far we've hit 39.7 without a rear end

and the science behind it is that as the top of the wheel is effectively going twice the speed it has 4 times the drag and therefore needs 8times the power to overcome said drag.

i dunno just a thought..

There's a restriction on the hight of the front wing and on the size of endplates.
However, for sure teams will try to lessen the darg front wheel generates by any means. i think that probably outer part of profiles of the wing would be with the maximum avaible AOA, whilw the inner would be flatter.

I've been reading the rules again... maybe this helps:




3.7.5 The bodywork ahead of the front wheel centre line and between 750mm and 840mm from the car centre line must have a projected area of no less than 95,000mm² in side view.

As of 2008, in side view, the endplate can be as big as 110,000mm² (550*200, or 350-900mm ahead of the front wheel center line and 150-350mm high).

According to 2009 rules, the endplate is located between 75-275mm high and 450-1000mm ahead of the front wheel center line, which results in the same 550*220=110,000m². Endplate's size is not reduced in comparison to 2008. Actually, its area has to be >=95,000mm² out of 110,000mm²!

Furthermore, article 3.7.5 above gives the endplate a specific location beteween 750 and 840mm from the car center line.




3.7.6 Bodywork ahead of the front wheel centre line and between 840mm and 900mm from the car centre line must have a projected area of no less than 28,000mm² in plan view. Furthermore, when viewed from underneath, the bodywork in this area must form one continuous surface which may not be more than 100mm above the reference plane.

This is the edge of the front wing (flips, vortex generators and stuff like that)

In plan view, the area is 33,000mm² and must have 28,000mm² of bodywork in it.

Then, when viewed from underneath, bodywork in this area cannot be higher than 100m, which means it can be no more than 25mm high if we consider the bottom of the endplate as a "reference plane". This can't be anything but the bernoulli thing I think, just like current cars.



Here's a quick sketch:

3.7.5 in green

Great work mariof1 , =D>

Could it be possible to post an analogous sketch for the rear wing as well

Images are always better than words

[mariof1]

Ok, this is the rear wing:





Rear or front view

Maximum of two elements in the green area and one in the blue area. Orange is the maximum area for endplates. Bodywork is also permitted in the light green area.




Plan view

Bodywork in the light green area must be between 200 and 400mm above the reference plane





Side view

There must be 330,000mm² of bodywork in the orange area (total is 390,000mm²)

@marioF1

Thank you. That is very helpful. =D>

[smirkoff]

Great, marioF1,

I'll try to do the adaptation for the front wing of my model following your drawings. The rear wing is right into the measures, although it's only an adaptation of a 2007 wing of a previous model.

[Ogami musashi]

Smirkof first congratulations for your model.

I'm not quite sure about the squarish sidepods. There's indeed a minimum radius, but curved shape stays possible.
Also please note that the radius imposition only works from 100mm above the RP which is about 50mm above the flat bottom.

Other than that and the front wing as suggested bymarioF1 i think you're spot on.

Thanks again.

Great work once more mariof1 , a 1000 thanks

[smirkoff]

Also please note that the radius imposition only works from 100mm above the RP which is about 50mm above the flat bottom.

Many thanks, Ogami,

actually I've tried to apply some of the small design freedom permitted by the rules as mentioned by you in my model. It's really curved inwards in the "carbon exposed" part between the end of the sidepod and the step plane, a bit just like it was in the late-2000 season Jordan EJ10, or before in the Minardi 194. The lighting of the scene doesn't help to notice the curved shape at that spot. I hope I'll have some time in the next days to do a revision of the model and render some other views.

Thanks again!!

[Ogami musashi]

i thank you, this is a great thing to do a full 3D model.

Ok, this is the rear wing:





Rear or front view

Maximum of two elements in the green area and one in the blue area. Orange is the maximum area for endplates. Bodywork is also permitted in the light green area.




Plan view

Bodywork in the light green area must be between 200 and 400mm above the reference plane





Side view

There must be 330,000mm² of bodywork in the orange area (total is 390,000mm²)

On which yrs regulation is this drawing based? because according to the 2008 technical regulations, it says that
"No part of the car behind the rear wheel centre line may be more than 800mm above the reference plane.

and in this drawing..it looks like the rear wing is 950mm above the reference plane.
can u please explain?

[mariof1]

In fact it is in accordance with 2009 regulations

[rjsa]

In fact it is in accordance with 2009 regulations

@Mariof1: In the front wing plan view, the proportion between the main profile and the flaps (chord length) is according to the rules or is just an illustration?

TIA,

Ricardo

[pranav]

In fact it is in accordance with 2009 regulations

Thanks "mariof1"

by the way awesome drawing!!! =D>
