Abstract
An airfoil assembly having a trunnion and a spar. The trunnion having an inner surface defining a socket with a flared section with an open top. The spar extending from the socket and through the open top. Further, the spar being formed by a plurality of composite plies including a radially innermost ply having a respective centerline, and a radially outermost ply having a respective centerline that is parallel to the respective centerline of the radially innermost ply.
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 trunnion defining a socket, the socket having an opening formed along a top surface;
- a spar extending from the interior of the airfoil body and through the opening into the socket, the spar having a spar centerline and a flared section terminating at a distal end within the socket, the flared section being formed by a plurality of composite plies comprising:
- a radially innermost ply having a respective centerline;
- and
- a radially outermost ply having a respective centerline that is parallel to the respective centerline of the radially innermost ply;
- and
- an inner sleeve extending along at least a portion of the radially innermost ply, the inner sleeve having a sleeve centerline that is parallel to the respective centerline of the radially innermost ply and the respective centerline of the radially outermost ply.
