My F1 car - LegendaryM

[r.singh]

Hello ,
I am new to F1 tech.I work with Formula Student Race Car team of my university.I am responsible to develop an Aero-Package for the car from scratch.Ou team has no experience in this.My idea is to select few appropriate wing profiles from database,model them using different shape of end plates & then do CFD.Based on results of CFD ,I want to decide on design.
But I am facing a problem with CAD modeling in NX(Unigraphics)..Dat file is not importing well..
can anybody help here.?

Hello LegendaryM,

I am a current Level 3 Engineering student and one of the units we as students has to complete is an engineer project which lasts thoughout the year. I am looking into how to prevent a Formula one car from flipping. This is rare for modern Formula 1 cars but when it does occur it can be fatal. I have decided to adap the roof flaps which are used in NASCAR to a Formula 1 car and need to create a solid works model of these roof flaps attached to an Formula 1 car.

Looking through the other posts on this forum other people has left an email address and requested your solid works model. I was wondering if you could please send me the file of your Formula 1 car in solid works form so that I can attach the roof flaps to it for my engineer project. Also your model is so detailed it will realy help me to explain in my final presentation all the components of an Formula 1 car. Our project requires me to contact a Formula 1 team when this is required I will make clear that the design of the car is not mine and that I asked your premission first. I will also make it clear in my final presentation.

Thank you you taking the time to read this post. Here is my email address below:

So the 2012 car, albeit rather late:

The new car is designed completely from scratch, which is the main reason it has taken so long. No parts are carried over from last year.






Starting at the front, the front wing is a development of the one a posted in December.

Its a fairly conventional front wing, and i plan to update it soon, but its also the first front wing ive made which fully complies with 3.75 and 3.4.2, which relates to thickness in the outer section of the wing.


Ive copied williams/sauber and have incorporated the brake ducts into the blade. The lower front suspension also mounts onto the wheel higher to reduce blockage from the front wing


The sidepods are more conventional on this car, although i think the old ones where unrealistically small. There is a cooling exit on top of the sidepods. I plan to update the pod-vane by making it curve over the top of the sidepod like sauber.


Although the front of the floor is not in any way revolutionary, it is much more refined than previous designs I have done, especially where the leading edge meets the splitter.


The airbox is conventional, with a fairly large undercut. This is the first car ive designed which fully complies with 3.8.4; a minimum 75mm radius is maintained all over the areas needed, whereas on the old car sometimes i had to reduce it to 50mm


The exhaust exits as far forward as possible and quite wide out. I designed the exhaust position after doing the sidepods as i dont think compromising the airflow to the rear of the car as much as sauber is worth it. That said, the exhaust is aimed to blow towards the area inside of the rear of the tyre, although i would have to do cfd to see if it actually was.


I have also incorporated the rear brake ducts into the blade. I have added alot of winglets onto the rear of the brake duct and the top rear suspension members are at a much more realistic angle. The drive shaft is also at a less extreme angle, although the rear of the car is still very low


Here you can see how low the rear impact structure is to get the best possible flow under the beam wing, and the second cooling exit. I have incorporated the a limited ddrs into the car, though at the moment it only stalls the beam wing


The rear wing is fairly conventional, ive copied ferrari style cutouts. You can also see how thick the rear wing endplate is to house the tubing for the ddrs


The diffuser is not radical, but refined in my opinion. It exits partly to the side in a similar fashion to lotus. I also have a small cutout in front of the rear wheels which i also had last year. I dont have a hole for the gearbox starter hole yet ala red bull as i plan to do something involving the ddrs in this area.



The main innovation/ trick on the car is the last bit of the exhausts.
5.8.3 states that the last 100mm of the tailpipe must have a maximum diameter of 75mm and point at least 10 degrees upwards. This is problematic as I want the exhaust gases to go downwards. What' ive done is nozzle the exhaust before the last 100mm and make it horizontal so the exhaust gases should exit horizontally and not 10 degrees upwards, making it easy for the downwash effect to work

Which soft did you use to make those models??? Thanks!!

with the top edge being continuous (without the step at the bottom) wouldn't the gas attach to that surface and suck the flow upwards and you'll just have disturbed flow in the bottom after the step???

a very crude, quick drawing explaining what i mean

EDIT: I have uploaded the model so it can be viewed in a browser with solid edge viewer: http://www.filefactory.com/file/aghfbc3/n/DR09B_exe

Can anyone tell me if this file is still available for download?

[luminado]

Impressive and creative. Good to see the model you create. I like that clever exhaust solution. It is really smart way. Let me know how is going buddy. best of luck.

Dear LegendaryM,
I am very interested in your project and I am impressed in what you have designed!
Is there any way that you could update the links to an old or new version of the CAD file of your F1 car?

Thank you in advance,
Dennisdn

Sorry to resurrect at ~8 year old post, but I found some of the old CAD files for this project and put them on OnShape if anyone would like to have a look. Unfortunately they're only dumb surfaces and there's no assembly of the whole car, but hopefully a few people will find this interesting:

Nice!

[humble sabot]

The old picture links are dead. What does this thing look like again?
NVM, the onshape page loads them up. But it is exceedingly slow.
Thanks for the share
