Abstract
A method for engaging a drive shaft of a turbo engine with an output shaft by means of a clutch is provided. The turbo engine is run up to a rotational speed that is subsynchronous to the speed of the output shaft and is maintained at the steady speed before a signal is set or before starting the engagement process.
Claims8
A method for clutch engagement of an input drive shaft of a continuous flow machine to an output drive shaft using a clutch, comprising:
- accelerating the continuous flow machine to a rotation speed which is subsynchronous with respect to the output drive shaft and is held at a steady rotation speed before a signal is set which starts a clutch engagement process;
- and
- setting the signal when a phase difference between two partial shaft trains is such that both centers of gravity are opposite.
