Combustor assembly with fastened combustor liner and head

A combustor assembly for a gas turbine engine, the combustor assembly comprising a combustor liner, a combustor head, a cowl and a fastener, wherein:

• the combustor liner and the cowl define a cavity, wherein the combustor liner includes a radially outer annular wall and a radially inner annular wall defining the cavity therebetween, wherein the radially outer annular wall and the radially inner annular wall define a combustion chamber of the cavity on a side of the combustor head remote from the cowl;
• the combustor liner has an integral combustor liner lug that extends radially into the cavity from one or more of the radially outer annular wall or the radially inner annular wall of the combustor liner toward the other of the radially outer annular wall or radially inner annular wall;
• and
• the fastener extends axially into the integral combustor liner lug to fasten the combustor head to the combustor liner,
• wherein the cowl is arranged axially adjacent to the combustor head, wherein an aft surface of the combustor head and an aft surface of the cowl each abut a forward surface of the integral combustor liner lug.
