Default Re: UPDATE: Counter-Rotating Disc Successfully Tested At Jennings

The only way I could understand what this thing even did was to watch the "1st test" video when they're going slow. The other videos and pictures didn't really let me see the reverse rotation.

Having this new system won't magically snap it into alignment, but keeps that natural precession (as seen in the circle slowly traced out by the pole of a spinning gyroscope) out of the equation. With this powerful (because of the weight of the tire, rim, etc.) force nullified, the rider can easily correct the alignment when the front tire touches back down. Seems like a pretty sound application of physics to me.



By the way I'd seen that hideous last wreck into the parked car, and I'm pretty sure the guy survived. A little harder, and the car might have been flipped onto it's roof!

I actually saw a half hour TV documentary dedicated to this guy (I'm sure you can find the whole video on the web). He was a mute, slightly crazy when it came to bikes. He survived the crash, the coma, and need facial reconstructive surgery. He's back to riding crazy (and his girlfriend was translating his sign language on the show).

No, he didn't. See the 5 minute long video here:

Lots of replays of the crash. Description of his injuries.

What an ass ... "to be old and wise you need to be young and stupid" he says



After seeing the video I am sorry he made it. An ******* like that is going to go on until he kills somebody else ...

The real question is, how well does a reverse-rotating rotor work with a car tire on the back?

I would like to see some figures reguarding parasitic power losses. It takes power to drive those gears. This is not measurable on a dyno, so I guess you would have to take it to the strip and see differences between a stock bike and the modified brake bike.

It's probably not all that much. You would have to spin up the rotors in the forward direction anyway, so you're really only looking at the mass of the gears themselves. The effect on acceleration is probably no where near what it is on handling due to the increase in unsprung weight.
