Abstract
Aspects of the disclosure are directed to a case for a gas turbine engine, the case including a case wall and a boss that extends from the case wall, the boss including a distal top contoured surface with a through hole fotmed there in, the distal top contoured surface having a non-uniform radial wall thickness.
Claims11
A case for a gas turbine engine, the case comprising:
- a case wall;
- and
- a boss that extends from the case wall, the boss comprising a distal top contoured surface with a through hole formed there in, the distal top contoured surface having a non-uniform radial wall thickness.
A case for a gas turbine engine, the case comprising:
- a case wall that defines a first thickness;
- and
- a boss that extends from the case wall, the boss comprising a distal top surface with a through hole formed there in, the distal top surface having a radial wall surface whose radial thickness is non-uniform.
A method of reducing stress in a case of a gas turbine engine, the method comprising:
- machining a radial wall of a boss so the boss has a non-uniform radial thickness.
