    Abstract: A propulsion system including a casing surrounding a fan rotor assembly is provided. An example casing includes an outer layer material, an inner layer material including first openings extended partially through the inner layer material along a radial direction of a first side of the inner layer material, and second openings extended partially through the inner layer material along the radial direction of a second side of the inner layer material opposite the first side, and a spring member coupled to the outer layer material and the inner layer material.

    Abstract: An airfoil defining a span extending between a root and a tip. The airfoil includes a retaining member extending at least partially between a leading edge and a trailing edge defining a frangible line extending at least partially along a chord at a point along the span of the retaining member. The airfoil further includes a frangible airfoil portion extending between the tip and the frangible line. The frangible airfoil portion includes a first plurality of composite plies, at least one composite ply of the first plurality of composite plies wraps around the retaining member. The airfoil includes a residual airfoil portion extending from the frangible line to the root including a second plurality of composite plies, at least one composite ply of the second plurality of composite plies wraps around the retaining member. Further, the residual airfoil portion meets the frangible airfoil portion at the frangible line.

    Abstract: An airfoil defining a span extending between a root and a tip and a chord at each point along the span extending between a leading edge and a trailing edge. The airfoil includes a leading edge sheath coupled to the leading edge of the airfoil. The leading edge sheath includes a flange extending from a frangible line toward the tip along the span and defining a first width along the chord at each point along the span S. The leading edge sheath further includes a base extending from the frangible line at least partially along the span to the root and defining a second width along the chord at a point along the span of the frangible line such that the second width is greater than the first width.
