My F1 car - LegendaryM

[wesley123]

lovely updates!

Though(as usual) i have some suggestions:
As you have added those small barge boards i do not see any need to keep the center one.

Also i would add two rear wing pillars instead of one, you can use those pillars to split the air to head through thwe hole and over the normal wing.

And as already told i would head for an mclaren style front splitter, i actually have also my own design ready(wich i might implement in my own car, but first i have to finish it lol) wich actually makes the nose cone some sort of wing, and then creates a splitter in that, on radiator intake height, wich adds flow to the radiator intakes, wich allows them to be smaller.

If I have 2 rear wing pillars instead of 1, then the have to join underneath the wing instead of ontop of it. Also regarding the williams/mclaren style splitter - i'm planning on putting one in and i have had one designed, but seperate from the model (just to find out exactly how it works, and how to model it) for a few months

A question for someone with really good aerodynamics knowledge: Would getting the front wing to stall on a straight reduce drag or would it mess up the flow further down the car, so have a net disadvantage

[LegendaryM]

Another Update:
I've added a williams/mclaren style splitter at the front



Also a new diffuser - the lower deck extends further outwards as the rear wing endplates no longer merge with the diffuser. The second deck is changed from a semi-circle outlet to a flat one to increase the exit area, and the underside of the crash structure is heavily sculpted

Really beautiful work, that diffuser is looking amazing. I like in particular how you have bent the further-most lower rear wing element onto the crash structure like that. Your crash structure is without a doubt, very sculpted and looks great. I'm not sure how much use that secondary lower wing element would be now, but looks cool anyhow. I would probably be more inclined to connect the central support pillar on the underside of the wing though, remember that the upper surface is high pressure, so that could have the potential to increase drag(by a small amount obviously). I like how you changed the upper part of the rear wing enplate too. Looks great, keep up the good work.

Wow! haven't followed this thread since it was about 10 or 11 pages long. Pascal your car looks great. Cant wait to see a rendered version of the rear of LegendaryM's car. The lower central piece on the diffuser looks quite interesting. I'll wait patiently to see any CFD.

Some more updates; focusing on reducing drag by causing wings to stall at high speed.
1. A new front wing. The highlighted element moves upwards and closes the gap, causing the wing to stall.




2. A new frontal lower rear wing element. Because it isnt in the normal wing areas, it doesnt have to pass a flex test, so the upper element (highlighted) flexs at high speeds, stalling the wing and therefore causing the diffuser to stall (as that wing drives the diffuser).

not very safe lol.

Stalling front wing isnt actually a good idea, as it screws up the airflow over the rest of the car, also i have huge doubts if the front wing does even stall.

Diffuser stalling would suck as then air would heap up causing enormous drag(if im correct), stalling is a reallty crap way to gain top speeds, rather make us of vortex generators etc.

It might, it might not, but i can't test it in a wind tunnel can I?

Didnt ferrari stall their diffuser in early 2007 or 2008?

I know you cant test it, but what i assume is that it wont stall, siply because of the AoA.

What ferrari did then was raising the floor on straights, allowing air to go through the bottom more freely, and back to normal for turns, so the car had less drag.

Also in 2006 they let their upper rear wing stall wich did decrease drag, this was the reason for the FIA to put in fixers so the slit couldnt be closed.

Also, wich i did came up is that your front lower rear wing element is part of the rear wing and thus needs to pass the test, it could be an idea to bend it to the diffuser, allowing it to be wider and sealing the rear tires off from the diffusers top, increasing its efficiency.

[LegendaryM]

Another update; i took onboard what wesley said about the aoa of the front wing perhaps not being great enough to stall it, so I have redesigned the front wing:
It now again has 2 lower elements, however instead of the moveable element pivoting around the front, it pivots around the back, so that the gap at the front between the 2 elements can be closed, which will cause the front wing to stall.
While doing this I have also redesigned the shape of the wing to make it smoother

[ESPImperium]

The rate of development on your car is out of this world. Still have the same worries over the legality of your front camera mounting posistions, but never the less the rate of development of your car is out of this world.

Howvever, I was looking at the new Virgin VR-01 today on the videon on their site, and do belive they have one of your previous ideas on their car, the rear wing centre section, how it is swept and sculpted to get as much downforce as posible out if it.

[wrcsti]

To be honest I dont get why you want to stall the wing, Now if you would design a movable front wing that can move into an angle that opened gaps between the elements to let air seep through. Also stalling a difuser is a nogo either as a diffuser usually decreases drag if well designed.
