PROBLEM TO BE SOLVED: To reduce the size and weight of a part-span shroud and fillets provided in a blade of a turbomachine.SOLUTION: A rotatable blade for use in a turbomachine includes: an airfoil portion having a leading edge, a trailing edge, a radially inner end and a radially outer end; a root section positioned at the radially inner end of the airfoil portion; and a part-span shroud located on the airfoil portion between the root section and the radially outer end. The part-span shroud decreases in width and thickness from the airfoil portion to a contact surface adapted to engage a mating contact surface on a part-span shroud of an adjacent blade. |
