Combustor liner attachment assembly for gas turbine engine

A method of assembling a combustor liner panel attachment assembly comprising:

• sandwiching a portion of a first liner and a spring element together;
• disposing a protrusion feature extending radially outwardly from the first liner within a recessed segment of the spring element to axially retain the first liner, the protrusion feature being part of the first liner;
• inserting a metal fastener through a portion of the first liner and the spring element;
• securing the first liner and the spring element together with a nut threaded to the metal fastener;
• and
• radially retaining the first liner and a second liner with a single T-head bolt having a shoulder that overlaps the first liner and the second liner.

A gas turbine engine comprising:

• a compressor section;
• a combustor section;
• a turbine section;
• and
• a combustor liner panel attachment assembly comprising:
• a non-metallic first liner extending from a first end to a second end, and circumferentially to partially define a combustion zone;
• a spring element located adjacent to a portion of the non-metallic first liner and operatively coupled to a stationary structure, the non-metallic first liner and the spring element being sandwiched together;
• the non-metallic first liner having a protrusion feature extending radially outward therefrom, the spring element having a recessed segment, the protrusion feature disposed within the recessed segment of the spring element to axially retain the non-metallic first liner, the protrusion feature being part of the non-metallic first liner;
• wherein a metal fastener extends through a portion of the non-metallic first liner and through a portion of the spring element to secure the non-metallic first liner and the spring element together with a metal nut threaded to the metal fastener;
• a second liner disposed circumferentially adjacent to the non-metallic first liner;
• and
• a T-head bolt having a shoulder in contact with a radially inner surface of each of the non-metallic first liner and the second liner such that the shoulder overlaps the non-metallic first liner and the second liner to radially retain the non-metallic first liner and the second liner, the T-head bolt allowing the non-metallic first liner and the second liner to thermally grow axially.
