Precessional vibrations and resonances of compound shells during complex rotation

A study is made of the problem of precessional vibrations excited in a thin-walled rotor with a branching meridional section by gyroscopic inertial forces during the complex rotation of the rotor. Methods of solving the problem are proposed. It is established that resonant vibrations may be excited while the rotor is undergoing complex rotation.
