Countering Torque

Ultra-high-speed flywheels, for energy storage, and flywheels used for vehicle traction energy rely on this principle for neutralising the resistance to turning that is developed as a result of rotation and large angular momentum. Larger ships sometimes have twin propellers rotating in opposite directions partly to improve manoeuvrability as compared to same-direction rotation.

Sir:

You already have the only solution........parallel counter rotation......

Great experience in "Drag Boat Racing".....best solution is two counter rotating engines (usually big block Chevies) to preclude induced tendency to flip when the prop comes out of the water and the boat rotational parasitic drag is reduced to air.

In some aircraft over sized prop/power (radil engines) to short wing ratio twists the plane in the air.

All leverage related.

MR. GUY

The Russians and the Brits tried contra-rotating props as one solution. On large twin screw submarines the work around was opposed screws (eg port ran clockwise, starboard ran counterclockwise) It's a bit frustrating, as I was hoping that we'd come a bit further than the days of the Fairey Gannet. ;) Thanks for the assist, but all and continuing ideas welcome.
