Turbomachine blade with improved stiffness to weight ratio

摘要

A system includes a turbomachine (20) that includes a stator (60) and a rotor (24). The rotor (24) is configured to rotate about a rotational axis (26,36) relative to the stator (60). In addition, the rotor (24) includes a least one rotary blade (52), and the at least one rotary blade has a tip portion (64) with a patterned structure (54) of beams (56) and cavities (58).
