SELF-ALIGNMENT AND BALANCING OF COAXIAL ROTORS,
Abstract
In modern gas-turbine engines wide application has been found for dynamic systems formed by two coaxial rotors turning with different values for their angular velocity. At high angular velocity of the rotors the basic problem of dynamics is the distribution of the critical numbers of turns outside of the zone of the operation velocities, the lowering of the vibration overloads and amplitudes of oscillations in the transition through the critical number of turns, the diminishing of the dynamic components of the support reactions, and the self-alignment of the rotors in the zone of operational velocities. One of the possible means of solving this problem is the making use of the effect of self-alignment of a rigid rotor turning in two elastic supports and the spreading of this effect over the system of coaxial rotors, which are turning with different angular velocities.
