A simplified traction dyno

A simplified traction dyno

(OP)
I've been promoting, at my site, that which I call a "traction dyno." This is nothing more than an adaptation of the constrained testing used in the automotive industry...before the use of full chassis fixturing...to quantify the effects of cornering loads on the chassis. I've simply rotated the tether 90 degrees in plan view to allow evaluation of traction effects.

In other words, this is a means of evaluating drag race suspension adjustments in the shop, without the need for even starting the engine.

While some racers have been using the procedure, many have complained that a convenient tether attachment point isn't available on the car, or in the shop, or both.

I've finally come up with a way to substitute a gravitational force for the tether force. While this provides only one data point, normal suspension linearity warrants extrapolation to the conditions existing at maximum launch acceleration.

The procedure description and a spreadsheet are on Page 37. I'm looking for questions and comments.

RE: A simplified traction dyno

Sorry, this is an 'inside' joke and you will not understand, but perhaps Isaac/Ivymike will post a link---

I just got an e mail about the "testing of a new Airbus 340-600 in France by an Arab flight crew from Abu Dhabi".  From my vantage point, it sounds like you may be headed in the same direction. ;o)
