Abstract
A hanger for use in a gas turbine engine exhaust system comprises a first bracket, a second bracket, a pin and a bumper. The first bracket is for connecting to an exhaust duct or liner of the gas turbine exhaust system. The second bracket is for connecting to an exhaust duct or liner of the gas turbine exhaust system. The pin extends through the first and second brackets to bring the first and second brackets into pivotable engagement. The bumper is positioned adjacent the first or second bracket to inhibit movement of the first bracket relative to the second bracket.
Claims20
A hanger for use in a gas turbine engine exhaust system, the hanger comprising:
- a first bracket for connecting to the gas turbine exhaust system;
- a second bracket for connecting to the gas turbine exhaust system;
- a pin extending through the first and second brackets to bring the first and second brackets into pivotable engagement;
- and
- a bumper positioned adjacent the first or second bracket to inhibit movement of the first bracket relative to the second bracket.
A suspension system comprising:
- an exhaust duct of a gas turbine engine;
- an exhaust duct liner disposed within the exhaust duct;
- a pin extending along a pin axis between the exhaust duct and the exhaust duct liner;
- a first bracket connected to the exhaust duct, the first bracket comprising:
- a first strap through which the pin extends;
- a second strap through which the pin extends;
- and
- first and second side rails connecting the first and second straps;
- a second bracket connected to the exhaust duct liner, the second bracket comprising:
- a first loop through which the pin extends, the first loop being positioned between the first and second straps;
- and
- a bumper positioned between the first loop and the exhaust duct.
An exhaust duct liner suspension system comprising:
- a first bracket having a first strap;
- a second bracket having a first loop positioned adjacent the first strap such that the second bracket is radially displaceable relative to the first bracket;
- a pin extending through the first strap and the first loop such that the first bracket and second bracket are circumferentially rotatable relative to each other, wherein the pin limits radial tensile loading between the first and second brackets;
- and
- a bumper positioned adjacent the second bracket to dampen radial compressive loading between the first and second brackets.
