Abstract : The author attempts to quantitatively evaluate the factors impeding efficient balancing of gyrorotors spinning at rates close to actual operating rates by investigating the performance of various balancing machines. A balancing machine with two rigid supports, equipped with pressure indicators for measuring dynamic pressures, a frame-type balancing machine, and a balancing machine with two movable supports were tested. It was found that it is impossible to improve the balancing of rotors using balancing machines with two rigid supports at high spinning rates without eliminating the play in the bushings and in the rotor shaft by introducing flexible elements. For this reason, the frame-type balancing machine must be provided with the means for displacing the frame supports in relation to the planes of correction. In a balancing machine with two movable supports, provision must be made for selecting the location of pressure indicators along the axis of the gyroscope.
