| Abstract |
A theory (mathematical model) of the precession of a flexible rotor with a cavity equally divided by radial baffles and partially filled with a low-viscosity liquid is proposed. Fluid vibrations self-excited in a rotating and precessing rotor with a small number of baffles (from 1 to 3) lead to specific system frequencies and dynamic instability in a range not associated with the usual synchronous critical speed. |
