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

Never mind Seruzawa's pessimism, maybe they could sell it to the insurance people in Quebec as the answer to the losses incurred by squids wrecking motorcycles.



A disk is a lot lighter than the full wheel, so they would have to really spin it FAST to exactly counter the gyroscopic torques. But then the calipers could be a bit lighter, I suppose.



I've seen the racers thowing their bikes back and forth through the Corkscrew at Laguna Seca. At that location, I'd think that counter-rotating disks would be a terrible idea.

Yea, by using a higher gear ratio the rotor could spin faster than the front wheel. A bonus would be the greater mechanical advantage the brake rotor would have over the wheel's turning for better braking.

This technology sounds right. But you need more testing and results must show in numbers. Money, you need more money for further testing and prototypes. Are you offering any investments? Count me in.

i believe i read in Cycle world that Rossi's GP bike has the engine rotate in the opposite direction as the wheels. They said this would make the bike less stable and allow it to turn in faster- same gyro principles as the counter rotating rotor thing. I guess yamaha decided it was worth the extra gear in its tranny to do this. This is for those of you who can't squeeze a drop of ***** out before asking a Honda or yamaha motoGP team for permission.

I wish the guy would give us some weight numbers for his prototype and maybe a weight estimate on a cast version.

This thing is brilliant.



I didn't know that the gyroscopic effect of something could be canceled with another one rotating the other way. I always assumed that the two gyroscopes would just add resistance together. Obviously, I never tried it. Interesting stuff.



In my head, it seems that it might be harder to actually lock the brakes too, seeing as they're spinning faster.

Yeah, and see how well that worked for them? It really makes much more sense for established, successful teams to go the conventional route. For teams that have nothing to lose it makes sense to try radical ideas. If something works well, the big guys can pick it up by buying the patent (or they can just wait until the patent expires, like BMW did with the Hossack front suspension on their new K1200).

Judging by the crappy website and video that doesn't really show the thing working. I'd say this guy is smart for creating something that will generate enough interest to get a lot of people to invest money into something that will never come to fruition.

I'm working on a motor that pulls in air through the exausts and expels it through the gas tank which now holds cheese.
