Abstract:
1. An airframe, comprising: a structural reinforcement member including a base flange and a leg extending from the base flange, wherein the structural reinforcement member has a terminal end region that includes a terminal edge of the structural reinforcement member; a skin operatively coupled to the base flange opposite the leg and extending longitudinally beyond the terminal end region of the structural reinforcement member, wherein the skin and the structural reinforcement member collectively define a run-out region encompassing the terminal end region of the structural reinforcement member and a portion of the skin adjacent to the terminal end region of the structural reinforcement member, wherein within the run-out region the skin is more flexible than within portions of the skin that are adjacent to the run-out region, wherein within the run-out region a recess extends into the skin on a side of the skin that is opposite the structural reinforcement member, wherein the recess extends into the skin opposite the terminal edge of the structural reinforcement member, and wherein the recess is longitudinally aligned with the leg of the structural reinforcement member; a plurality of fasteners extending through and operatively coupling the structural reinforcement member and the skin within the run-out region and laterally adjacent to the recess; and a splice plate coupled to the skin opposite the structural reinforcement member within the run-out region, wherein the splice plate extends across the recess.
