ABSTRACT:
An improvement to rotating blades is disclosed in a device that will impose anti-moment forces and result in less stress in the said rotating member. The device consists of a rotating body or gyro which is attached to the said rotating blades, and due to the precession of the gyros, a moment is developed which is counter to the moment forces that are normally imposed on the said blades.
