Abstract: A fixture assembly including a first fixture portion 202; a second fixture portion 204 that interfaces with the first fixture portion 202; and a bladder 206 assembly mounted to the second fixture portion 204 to face the first fixture portion 202. A method of manufacturing a fan blade (58) includes inserting a blade body 80 and a cover 82 into a fixture 200; and deploying a bladder assembly 206 within the fixture 200 to press the cover 82 into the blade body 80.

Abstract: An airfoil includes an airfoil body (110), a cover (120), and a stud (130). The cover (120) is disposed on at least one of a suction side (102) and a pressure side (101) of the airfoil body (110) and the stud (130) extends through the cover (120) and into the airfoil body (110) and the stud (130) is joined to the airfoil body (110) and the cover (120) by a friction weld. A method of manufacturing such an airfoil is also defined.

Abstract: Aspects of the disclosure are directed to a servicing of an airfoil of an aircraft engine. A first portion of a first bondcoat layer may be removed from the airfoil while leaving a second portion of the first bondcoat layer intact on the airfoil. A second bondcoat layer may be applied to the airfoil using a coating technique subsequent to the removal of the first portion of the first bondcoat layer.

Abstract: A directional translating clamping device (10) comprises a housing (12) that includes a distal housing end (14) and proximate housing end (16) separated along a central axis (18), and a housing recess (22) at the proximate housing end (16) and extending along the central axis (18). The device (10) also includes a slide (24) located in the housing recess (22), and the slide (24) comprises a slide recess (26) at a slide proximate end (28) co-axial with the housing recess (22), and a detent (30) in a radial sidewall of the slide (24) prevents the slide (24) from translating beyond a predetermined axial distance along the central axis (18). A spring (32) is located in the housing recess (22) and exerts an axial force on a distal end (33) of the slide (24). A stub shaft (34) extends from the distal end (14) of the housing (12). A roller ball assembly (36) includes a threaded sidewall that engages with the slide recess (26) to removably and replaceably secure the roller ball assembly (36) to the slide (24).

Abstract: A fixture assembly 200 includes a first fixture portion 202, a second fixture portion 204 that interfaces with the first fixture portion 202, and a sub-fixture 206 movably mounted to the first fixture portion 202. A multiple of actuators (208) selectively move the sub-fixture 206 toward the second fixture portion 204. A method of manufacturing a fan blade (58) includes deploying the sub-fixture 206 from the first fixture portion 202 to effectuate a peripheral diffusion bond to join the blade body (80) and the cover (82) of the fan blade (58).

Abstract: A fan blade includes first and second titanium portions that are secured to one another with an aluminum alloy braze. A method of manufacturing a fan blade includes providing first and second titanium portions, applying an aluminum alloy braze to at least one of the first and second titanium portions, and heating the fan blade to melt the aluminum alloy braze and join the first and second portions to one another to provide a fan blade with an airfoil exterior contour.
