Abstract
It would be desirable to be able to predict the running characteristics of turbo-generators at the design stage. The paper describes tests on production generators and their component parts, directed at evaluating the relative contributions of these components to the dynamic behaviour of the complete system. Tests have shown that the contribution of the rotor alone may be estimated with some confidence, but that the present state of knowledge regarding the rotor supports, whose characteristics are shown to have a profound effect on the running behaviour of the machine, is inadequate. Theoretical techniques are presented which should rigorously solve any practical configuration provided the correct parameters are available.Keywords
