My design

Here are our CFD links and discussions about aerodynamics, suspension, driver safety and tyres. Please stick to F1 on this forum.

The cars already have enough cooling issues, which is why they use the inclined radiators for more radiator for their limited frontal area. Also, isn't one purpose of chimneys to help suck more air into the radiators? It seems like they have trouble with cooling on the radiators of that size to me.
Size doesn't matter :wink:

No seriously, don't take dimensions and positions on my drawings as a definitive or scale. I also think that more longitudinal position of radiators instead of what we have today would enable use of much bigger radiators (hope this is visible on the drawings).

Yes I'm trying to reduce drag buy decreasing direct confrontation of radiators with air stream hoping that huge amount of air flowing trough the tunnel would be able suck out (pick up) air from the sidepods that is ATM+ while the air in the tunnel is ATM-. Just as air in the diffuser of a carburetor sucks out fuel.

Even more, in carburetor fuel is ATM= and the air is ATM-, while here, the difference between pressures is much greater for sidepods air is ATM+ and tunnel air is ATM-.

*ATM = atmospheric pressure

You could compare it with cooling on fan ground effect cars where sidepod inlets were minimized because the fan was enabling sufficient air flow. My tunnel acts like fan and therefore I believe that this system enables significant reduction of sidepod inlets – reduction of drag.

Apart from that, I’m very curious what would the gain of overall aero efficiency be having in mind much narrow slipstream for the air could flow in huge amount around the monocoque without going so wide or being choked in sidepods as it is the case on modern F1 cars.

Greater stability and speed seam to be gained too using trimaran advantages.

This system works using Venturi tube & Bernoulli equitation principles forgot to mention this but believed that it is obvious.

That reverse coke design has a lot of materials in the drivetrain. To me, it's excessive, and the inertia of those parts would have a definite effect on acceleration or braking. I think it would add mass, parts, and complexity.
And I would believe that only some form of trailing link suspension would be used, and that limits the design of the suspension.
Sorry, I think that this cool concept has some very serious design limitations.

You're right. A way around it would be with chain drives?

For me it was around the seventies and it was mind boggling when the teams would introduce the new cars, so part of my reason for doing these is because the new car introductions have become tediously boring in comparison. [/img]
I grew up spending much time in a workshop and garage with my grandfather, father and uncle so technical stuff was with me since the early childhood. I can remember watching F1 and racing in general from early '80s and the interest only rises as the time goes by.

But I'm not of those who think that history begun when they became aware of the world that surrounds them so I constantly explore what was before I can remember in order to have better understanding of presence and hint of a future... For example, Turbo charger and Variable valve actuation were invented and patented by Louis Renault in 1902!

I presume that majority believes that for example Variable valve actuation was invented by Toyota or BMW in the late ‘80s or ‘90s…

Regarding your reversed coke bottle concept….Did you consider using gearbox/diff. assembly attached to the engine crankshaft in the middle? It has been done in the late ‘80s by some company (I can’t remember it).

They used geared flywheel wheel in the middle of the crankshaft and it distributed power outside to another gear of the gearbox/diff. assembly attached to the middle of engine block. This enabled use of 100% transversally positioned engine with gearbox/diff. assembly in the middle which also enabled that half-shafts have identical length.

I just cannot find any links for you all, but I have seen a picture of a venturi car design dating from the early 1900's! It clearly shows a venturi underside to exploit bernoulli's theorum. I am fairly sure it is seen in "Aerodynamics of Road Vehicles - by Wolf-Heinrich Hucho"

I like your curious mind - keep up with the ideas.

I testing the concept of using the increased airflow as a venturi to improve radiator flow for a FSAE car using CFD a long time ago. I think the problem was that when we tested different angles, a lot of drag was caused by changing the flow direction to go through the radiator. We found it was best to leave the radiators normal to the flow. to get the best flow rate through the radiator compared to the drag on the vehicle. If you have an internal hole through the body, there would be lot of due to effects of junction drag and from the increased surface area causing more skin friction.

I think it is really cool people are thinking out of the box.
