SERVICE-FRIENDLY CROSS FLAME TUBE WITH TWIST LOCK ATTACHMENT FOR CAN-ANNULAR GAS TURBINES

摘要

A twist lock attachment mechanism for attaching a cross flame tube to a cross flame tube port that is part of a combustor basket in a combustion section of a gas turbine engine, where the cross flame tube includes opposing flange sections coupled to an end of the cross flame tube and being spaced apart from each other. The attachment mechanism includes an annular collar mounted to the cross flame tube port and first and second spaced apart flange extensions mounted to the annular collar, where each flange extension includes a slot open at one end and blocked at an opposite end. The flange sections of the cross flame tube are positioned between the flange extensions so that the flange sections align with the slots, and the cross flame tube is rotated in a manner that causes the flange sections to slide into the slots.

1. A twist lock attachment mechanism for attaching a cross flame tube to a cross flame tube port that is part of a combustor basket in a combustion section of a gas turbine engine, said cross flame tube including opposing annular flange sections formed to an end of the cross flame tube and being spaced apart from each other, said attachment mechanism comprising:
an annular collar mounted to the cross flame tube port; and first and second spaced apart flange extensions mounted to the annular collar where each flange extension includes a slot that is open at one end and blocked at an opposite end, wherein the flange sections of the cross flame tube are positioned between the flange extensions so that each flange section aligns with one of the slots, and wherein the cross flame tube is rotated in a manner that causes the flange sections to slide into the slots and secure the cross flame tube to the cross flame tube port.
