Blade retention scheme using a retention tab

摘要: A turbine blade retention system, for use with a rotor hub disk peripheral circumferential array of spaced apart slots extending between the forward and rearward faces, each slot having radially inward floor side walls adapted sliding engagement root blade. The has bottom surface which when engaged in slot, is from adjacent thus defining gap faces at said selected broach angle. tab an elongated web thickness less than including preformed transverse flange first end second that extends bent on installation into flange. to be disposed rests permit while engages one disk. includes least two deformable protrusions height exceeding gap, so deform secure outward during grinding tip example.
