Abstract
A mounting bracket of a gas turbine engine includes a first mounting flange configured to connect the mounting bracket to a casing of the gas turbine engine, a second mounting flange configured to connect a component to the mounting bracket, and a bracket leg extending between the first mounting flange and the second mounting flange. The mounting bracket has a first stiffness when a load is applied in a first force direction and has a second stiffness different from the first stiffness when the load is applied in a second force direction opposite the first force direction.
Claims15
A mounting bracket of a gas turbine engine, comprising:
- a first mounting flange configured to connect the mounting bracket to a casing of the gas turbine engine;
- a second mounting flange configured to connect a component to the mounting bracket;
- and
- a bracket leg extending between the first mounting flange and the second mounting flange;
- wherein the mounting bracket has a first stiffness when a load is applied in a first force direction and has a second stiffness different from the first stiffness when the load is applied in a second force direction opposite the first force direction;
- wherein the first mounting flange extends perpendicularly from the bracket leg;
- wherein the first mounting flange is configured to abut a casing boss protruding from the casing assembly;
- and
- further comprising a side flange extending from the first mounting flange, the side flange configured to extend along a side surface of the casing boss.
A casing and component assembly of a gas turbine engine comprising:
- a casing assembly of the gas turbine engine;
- a component assembled to the casing assembly;
- and
- a mounting bracket to secure the component to the casing assembly, the mounting bracket including:
- a first mounting flange configured to connect the mounting bracket to the casing assembly;
- a second mounting flange configured to connect the component to the mounting bracket;
- and
- a bracket leg extending between the first mounting flange and the second mounting flange;
- wherein the mounting bracket has a first stiffness when a load is applied in a first force direction and has a second stiffness different from the first stiffness when the load is applied in a second force direction opposite the first force direction;
- wherein the first mounting flange extends perpendicularly from the bracket leg;
- wherein the first mounting flange abuts a casing boss protruding from the casing assembly;
- and
- further comprising a side flange extending from the first mounting flange, the side flange configured to extend along a side surface of the casing boss.
A gas turbine engine, comprising:
- a combustor section;
- a turbine section driven by products of the combustion section;
- a compressor section driven by rotation of the turbine section;
- and
- a casing and component assembly including:
- a casing assembly of the gas turbine engine to which the component is assembled;
- a component assembled to the casing assembly;
- and
- a mounting bracket to secure the component to the casing assembly, the mounting bracket including:
- a first mounting flange configured to connect the mounting bracket to the casing assembly;
- a second mounting flange configured to connect the component to the mounting bracket;
- and
- a bracket leg extending between the first mounting flange and the second mounting flange;
- wherein the mounting bracket has a first stiffness when a load is applied in a first force direction and has a second stiffness different from the first stiffness when the load is applied in a second force direction opposite the first force direction;
- wherein the first mounting flange extends perpendicularly from the bracket leg;
- wherein the first mounting flange abuts a casing boss protruding from the casing assembly;
- further comprising a side flange extending from the first mounting flange, the side flange configured to extend along a side surface of the casing boss.
