Abstract

Transient response of an overcritical high-speed rotor is considered. A rapid increase of unbalance initiates a series of rotor-stator collisions succeeded by full annular rub during which a very high dynamic load can develop, exceeding by several times that due to separate collisions. The main reasons leading to such a potentially catastrophic response are highlighted.
