ROTOR WITH INTEGRATED BLADE

摘要

PROBLEM TO BE SOLVED: To considerably reduce a weight and a cost.

SOLUTION: A rotor assembly 10 with integrated blade used in a gas turbine engine comprises a plurality of pairs of airfoil blades 18. Each pair of the plurality of pairs of airfoil blades 18 has a spur extending from a tip of the first pair among the pairs of airfoil blades to a tip of the first pair among the pairs of airfoil blades. The rotor further includes: an outside shroud 12 which integrally joins the first and a second tips to each other in the respective pairs of airfoil blades 18; and an inner diameter hub 14.
