Actuator lever for setting the angular position of guide vanes in a turbo machine

The lever (40) has an intermediate part (44) connecting ends (42, 48) of the lever, where the end (42) has a thickness and a width greater than that of the part (44). The part (44) and the end (42) have predetermined shapes and dimensions to increase natural frequency of the lever in flexion and in...

Beschreibung
Zusammenfassung:	The lever (40) has an intermediate part (44) connecting ends (42, 48) of the lever, where the end (42) has a thickness and a width greater than that of the part (44). The part (44) and the end (42) have predetermined shapes and dimensions to increase natural frequency of the lever in flexion and in torsion beyond vibration frequencies of a turbomachine and to maintain stiffness of the lever. An independent claim is also included for a compressor of a turbomachine having vanes and an actuator lever.
