Great info. I was in the timing trailer announcing the run as it went side ways right in front of us. Mike did a great job & save. Thanks for sharing it and so others know what can happen at speed and with the damp salt. :cheers:

intriguing to ponder to what degree the aero characteristics of the car
played into/impacted the "save"

No flat sides, makes a big difference, Terry even mentioned this to Rick Vesco  as he has designed all of the liners with round surfaces and Terry built this liner the same way.

I would put the car shape and Mike's driving as about 50/50 for the save. That big tail fin makes a lot of force to straighten the car out and as Glen said the car does not have flat sides to trip over. Interesting watching the vid in the amount of wandering the car did before it got to the 3 mile mark. I wander if it was Mike looking for traction or the car not being stable.

A great save! and I hope that they go 450!

Why would round sides be better in a spin situation?  Less aero induced tipping force on a sideways moving vehicle?

Extremely informative insights. The simultaneous front, rear, and cockpit video shows the progression of events quite clearly.

Thank you very much for sharing all this.

Practically looks like its slaloming the 3 miles gates. 

Nish, Speed Demon, Copeland.  How many others got in trouble at the 3 mile over the span of that week?

Curious to know, when the steering is at full lock, how many degrees is that at the front wheels?

I spoke with Terry last night and he said they really didn't want to do that again.  :-o  :cheers: Wayno

I think 5 degrees lock to lock.Thats what the two Vesco liners have.

Cp & Cg article (was: 2015 The Year Ahead (Nish Motorsports))
« Reply #29 on: April 06, 2015, 11:23:22 AM »
Eva put up an article about how to calculate Center of Pressure (Cp) and Center of Gravity (Cg) on her new science on-line magazine Science Envy.
http://scienceenvy.com/race-car-engineering-400-mph-how-to-stay-straight-and-on-track/
It is a spruced up version of our article we posted on Landracing.com a while ago, with a few newer pictures. (We wrote this article at the urging of Tom Burkland and Rex Svoboda.)

The Speed Demon team and the Nish team have graciously come forward with their best theories of what caused their difficulties during the 2014 season. Both teams suspect that the Cp and Cg relative positions may have moved during the development of their vehicles and may be the root cause of the instability in their vehicles. We thought it would be a timely moment to re-publish the article to explain the physics behind Cg and Cp placement, since we all face these issues.

Our vehicle, the KillaJoule, runs like on rails, (so far, knock on wood) so this method for estimating Cp and Cg placement has worked for us, so far.....
