Abstract
A gas turbine engine includes a fan section, a compressor section, combustor section, and turbine section in serial flow arrangement, and defining an engine centerline. An airfoil is located in one of the fan section, the compressor section, or the turbine section. The airfoil defines an interior and extends between a leading edge and a trailing edge defining a chord-wise direction, and extending between a root and a tip defining a span-wise direction. At least one stiffener is located within the interior, having a deformation threshold, and including at least one crush initiator formed on the at least one stiffener. The crush initiator determines deformation geometry of the at least one stiffener in response to a force acting on the at least one stiffener exceeding the deformation threshold.
