The Remarkable Turbomachinery-Rotordynamics Developments During the Last Quarter of the 20th Century 2015-01-2487

Rotordynamics developed from the beginning of the 20th century to deal with problems associated with steam turbines. This paper deals with intense developments starting around 1975 through 2000 in rotordynamics to deal with new, larger machines running at higher speeds and higher power levels.
