CAD Modeling for Championship Touring Cars in the field (Argentina)

By Ricci Walker

Now I would like to talk about modeling airboxes and carbon fiber.

This Air Box I had to model at short notice like 2 hours on several occaisions

 

My job was to bring a fresh approach to EF Racing whether by process or technology,

so one day sat with the teams Alias Modeler talking about what he had designed the subject of frontal area sprung forth, as it does, more precisely the regulations that govern how much of the air intake was allowed to be above and below the vehicles horizontal midline. If you are going to model an air box for rapid prototyping you need to talk with the guy that’s going to model the aperture in the front end that the air box is going to fit to. Hed is also changing his front end all the time.

For those that are not familiar with motor racing

a set of rules are drawn up for all teams to abide by  allowing an equal playing field whilst using different makes shapes and sizes of production cars, i.e., ford, Peugeot, Honda, etc.  One of the fairest ways to level the playing field is to limit the engine size and air intake size. This allows plenty of scope to be creative within the boundaries of the legislation however it stops teams chucking sheds loads of money at quick fixes for getting ahead of the competitors.  Many of the manufacture backed teams have been running for years and so the development process has undergone large advances for little initial financial input to very small gains for huge amounts of money, and now to gain a hundredth of a second is akin to moving a Small Mountain from Chili to London.

The teams now try to buy people who can make a difference;

i.e. me from F1, and others from the world rally teams. For example my team purchased a production car, shipped it to “MIRA” the UK’s only independent wind tunnel facility to get full airflow analysis data. This cost tens of thousands and then gave the new vehicle away because it was cheaper than shipping it back to Argentina.

Alias and Catia modelers are always kept busy, modeling the underbody

sump guarde and the milled suspension brackets you can see here, so you can see motor racing is about being creative and adaptable whilst adhering to the regulations. To the casual observer motor racing is black and White but really its grey as the boundaries blur between what the governing body can see and what they are allowed to see. This is the most exciting aspect of the sport for me and really stimulates the creativity glands.

Now back to frontal area, mechanically speaking air is drawn into the engine via the air box which is connected to the engine, the size is fixed by the regulations; however there is a bonus that standard road cars remove called the ram air effect, the process where moving forward forces extra air into the engine enhancing the air/fuel mixture, this is power for free if the ecu (engine control unit) is mapable. The downsides are air flow restriction when closely following the car in front.

I am busier than ever these days

with contract modeling, teaching one to one students from all 5 continents and now of course my brand new website has gone live and it is possible to learn Alias Automotive to a professional level for the lowest rate on the planet.

Pictured below is an Audi A5 Sportback built by one of my students who is now a Digital Sculptor for GM.

Full HD video, just click the picture below

I am now putting some of my tutorials on YouTube, so whilst you’re there you may wish to check them out. There’s a full tutorial on how to create a Ball Corner to Class A Surfacing, Catia V5 spec.

For student’s who have the objective of finding a CAD job in the near future, I still teach One to One students and all of these students get Automotive Modeling or Design/Modeling jobs, so it’s a great investment to make.

Check-Out my Customer Feedback,

Many of my students make it to the top and succeed in becoming pro. Alias Digital Modelers. The hourly rate is very high and there are vacancies in UK. France, Germany, USA, Brazil etc.

On my website I teach you how to build the models you need to get accepted at interview. Why not take a look?

Cheers
