Abstract:
An unshrouded turbomachine impeller is disclosed. The impeller comprises a hub and a plurality of sequentially arranged blades. Each blade extends from a blade root at the hub to a blade tip and is comprised of a first blade edge and a second blade edge. A flow vane is formed between each pair of neighboring blades. A connection member extends across each flow vane between neighboring blades and rigidly or monolithically connects a first modal displacement region of a first one of the pair of neighboring blades to a second modal displacement region of a second one of the pair of neighboring blades.

Claim (Index 1):
An unshrouded turbomachine impeller comprising:\n a rotation axis; a hub; a plurality of sequentially arranged blades, each blade extending from a blade root at the hub to a blade tip and comprised of a first blade edge and a second blade edge, the first blade edge and the second blade edge extending from the hub to the blade tip; and a flow vane arranged between each pair of neighboring blades; wherein a connection member extending across each flow vane between pairs of neighboring blades connects a first modal displacement region at a certain frequency of a first one of said pair of neighboring blades to a second modal displacement region at said frequency of a second one of said pair of neighboring blades; and wherein each connection member has a first end rigidly or monolithically connected to a pressure side of a first one of said pair of neighboring blades and a second end rigidly or monolithically connected to a suction side of a second one of said pair of neighboring second blades, or vice versa.
