Abstract
An airfoil assembly for an engine having an airfoil body, a composite spar, a sleeve assembly, and a set of paddles. The composite spar having an interior spar portion located at the interior of the airfoil body and an exterior spar portion exterior of the airfoil body. The sleeve assembly comprises an outer sleeve and an inner sleeve. The set of paddles can extend from the inner sleeve or the outer sleeve towards the other of the inner sleeve or the outer sleeve.
Claims20
An airfoil assembly for an engine, the airfoil assembly comprising:
- an airfoil body comprising an outer wall bounding an interior, the outer wall extending between a leading edge and a trailing edge in a chordwise direction, and between a root and a tip in a spanwise direction;
- a composite spar having an interior spar portion located at the interior of the airfoil body and an exterior spar portion exterior of the airfoil body;
- a sleeve assembly comprising an outer sleeve and an inner sleeve circumscribed by the outer sleeve, wherein at least part of the exterior spar portion of the composite spar is received at a radially outer surface of the inner sleeve;
- and
- a set of paddles extending from the inner sleeve or the outer sleeve towards the other of the inner sleeve or the outer sleeve.
