Abstract
A stiffness boss for a turbine case of a gas turbine engine is disclosed. The stiffness boss includes a head portion disposed on an outer case surface of the turbine case, the head portion configured to provide rigidity in response to a transverse load being applied to the turbine case in a transverse direction. The stiffness boss also includes a leg portion disposed on the outer case surface of the turbine case and connected to the head portion, the leg portion configured to provide rigidity in response to an axial load being applied to the turbine case in an axial direction, such that deformation of the turbine case is resisted.

A stiffness boss for a turbine case of a gas turbine engine, comprising:
- a head portion disposed on an outer case surface of the turbine case, the head portion configured to provide rigidity in response to a transverse load being applied to the turbine case in a transverse direction;
- and
- a leg portion disposed on the outer case surface of the turbine case and connected to the head portion, the leg portion configured to provide rigidity in response to an axial load being applied to the turbine case in an axial direction, such that deformation of the turbine case is resisted.
A turbine case of a gas turbine engine, the turbine case comprising:
- an outer case surface;
- a support member boss configured to secure support structures of the gas turbine engine;
- a stiffness boss disposed on the outer case surface and configured to provide rigidity in response to one or more loads applied to the turbine case, the stiffness boss being different from the support member boss.
A method of fabricating a turbine case, comprising:
- disposing a head portion of a stiffness boss on an outer surface of the turbine case, the head portion configured to provide rigidity in response to a transverse load being applied to the turbine case;
- and
- disposing a leg portion of the stiffness boss on the outer surface of the turbine case, the leg portion configured to provide rigidity in response to an axial load being applied to the turbine case.
