IDENTIFY AERODYNAMIC PRIORITIES IN THREE STEPS

1. SUBMIT YOUR CAD FOR ANALYSIS

  

We work with CATIA V5, Siemens NX, Solid Works, ProE and more We can even work from scanned data in STL format Any level of detail, the more nuts and bolts the better!

2. WE DIVIDE THE CAR INTO SECTIONS AND RUN CFD

Our example has four elements but we can divide your car into as many parts as you like at no extra cost We can go to any level of detail including wishbones, push rods and wing mirrors

IDENTIFY AERODYNAMIC PRIORITIES IN THREE STEPS

3. WE PROVIDE AN AERODYNAMIC PRIORITY LIST

  

We list the components in order of performance In our example 10kg of drag is worth 5.7 kph at the end of the straight This lets you decide where to spend your budget Drag [kg]

NOW TAKE YOUR PRIORITY LIST TO THE WIND TUNNEL OR ASSESS CHANGES WITH OUR CFD

  

The body was top of the priority list in our example Your designer now makes a change to the engine cover and re-submits the CAD (we have experienced CAD and aerodynamic engineers to help make these changes if required) We’ll tell you how your change affects the top speed (or downforce/drag)

-

Body drag = 86 kg Top Speed = 347 kph

CHANGE TO ENGINE COVER -

Body drag = 75 kg Top Speed = 353 kph
