Abstract
The present application and the resultant patent provide an exhaust frame for a gas turbine engine. The exhaust frame may include an inner casing extending along a longitudinal axis of the exhaust frame, an outer casing positioned radially outward from the inner casing, a strut extending radially from the inner casing to the outer casing, and a relief groove defined in the inner casing or the outer casing and positioned about the strut. The present application and the resultant patent further provide a method for distributing stress concentrations in an exhaust frame of a gas turbine engine.
Claims20
An exhaust frame for a gas turbine engine, the exhaust frame comprising:
- an inner casing extending along a longitudinal axis of the exhaust frame;
- an outer casing positioned radially outward from the inner casing;
- a strut extending radially from the inner casing to the outer casing;
- and
- a relief groove defined in the inner casing or the outer casing and positioned about the strut.
A method for distributing stress concentrations in an exhaust frame of a gas turbine engine, the method comprising:
- providing an exhaust frame comprising:
- an inner casing extending along a longitudinal axis of the exhaust frame;
- an outer casing positioned radially outward from the inner casing;
- a strut extending radially from the inner casing to the outer casing;
- and
- a relief groove defined in the inner casing or the outer casing and positioned about the strut;
- and
- directing a flow of combustion gases through the exhaust frame, wherein stresses generated in the relief groove are higher than stresses generated in the strut.
A gas turbine engine, comprising:
- a compressor;
- a combustor in communication with the compressor;
- a turbine in communication with the combustor;
- and
- an exhaust frame in communication with the turbine, the exhaust frame comprising:
- an inner casing extending along a longitudinal axis of the exhaust frame;
- an outer casing positioned radially outward from the inner casing;
- a strut extending radially from the inner casing to the outer casing;
- and
- a relief groove defined in the inner casing or the outer casing and positioned about the strut.
