Abstract: A turbine engine that includes an engine casing including a shell and an angel wing member. The angel wing member includes a base defined at the shell and a tip positioned distal from the base. The turbine engine also includes a backsheet extending over the angel wing member such that an angled region is defined in the backsheet at an interface with the tip. The tip has a predetermined contour capable of mitigating stress concentrations in the angled region induced from said tip.

Abstract: A turbine engine that includes an engine casing including a shell and an angel wing member. The angel wing member includes a base defined at the shell, a tip positioned distal from the base, and a first side and a second side that define a thickness of the angel wing member. The thickness of the angel wing member is non-uniform between the base and the tip.
