I think Kev really hit the nail on the head.
Others may disagree, but I think of Engineering as solving a problem. In our context the problem is winning the competition (not necessarily true for...
The last few years Natsoft has been doing the timing for the events, it also keeps all the results on its website - which I think you can actually access live.

Thanks for the kind words guys.
MCoach,
There really isn't anything different between a 'diffuser' and a wing - all the principles remain the same. Airfoils also have a 'diffusing' section which...
Interesting discussion so far - although a little heavy on the 'gut feelings'.
Z is correct when he states that if you're looking to win economy/efficiency you should look to underbody aero...
For what it's worth, direct acting dampers are back on the table for us (Monash)in 2013. We ran them from 2006-2010, and managed to win 2 events and 1 design event with them. There are some...
Agreed, Haunted Hills is an amazing circuit. Perhaps if we can work it so cars do continuous laps without slowing down - with some dedicated marshaling/flagging this should be possible. Much better...
The lateral accel is in G's, with the yellow curve from a 3-axis Crossbow accelerometer, which is soft mounted with rubber and unfiltered in i2 (I think the crossbow might have some internal...
The G's spiked to about 1.9, ignoring roll angle.
Typically we don't bother accounting for roll angle as we run a pretty high roll gradient - 0.86% error at 2G cornering.
As for not accounting for...
Here's a bit of a diagram I just knocked up to help people understand the calculation:

The total wing package hasn't been finished (should be mounted in a week or two), but it's expected to be around 10-12 kg - approx the same as the 2010 package but a lot bigger. Every year we've been...
Just a heads up to all the Vic teams, there is another Khanacross (Basically an Autocross) at Bryant Park AKA Haunted Hills next Sunday (26th). It's about 1.5 hours east of Melbourne, near Moe.

More importantly, how many competitions have been lost due to a pneumatic/electronic shifter?
Thrainer,
We've done both on-track and theoretical (lap/comp sim) studies on the effects downforce and drag play on fuel usage. Interestingly, CL has a greater effect on fuel consumption than CD...
sbrenaman,
Generally speaking, the lower the rear wing the worse it operates (Lower downforce and lower drag, but at a lower L/D), however if you run an undertray you could get a boost from the rear...
The only way wings can make you lose points in Design Event is if the team doesn't justify them sufficiently. It’s the same for any major system on the car really.
I also wouldn't say wings will...
Hey Mikk,
There are a lot of myths about diffuser design so be careful what you believe. Probably a good idea to have a look at some literature on diffusers, Zhang has published some good work...
