Claims19
A method for working a combustor float wall panel having an existing cooling pin and a first contour comprising:
- adding a supplemental body to the combustor float wall panel, the supplemental body having a second contour, the supplemental body lacking the existing cooling pin;
- and
- attaching at least one second cooling pin to the supplemental body, the at least one second cooling pin being longer than the existing cooling pin.
A method for working a combustor float wall panel of a gas turbine engine comprising:
- separating the combustor float wall panel from a combustor of a gas turbine engine, the combustor float wall panel having an existing cooling pin;
- adding a supplemental body to the combustor float wall panel, the supplemental body lacking the existing cooling pin;
- attaching at least one second cooling pin to the supplemental body, the at least one second cooling pin being longer than the existing cooling pin;
- and
- returning the combustor float wall panel to the combustor of the gas turbine engine.
