Unitary flow path structure

A flow path assembly of a gas turbine engine, the flow path assembly extending from a combustor through a turbine section of the gas turbine engine, the turbine section including a first turbine stage immediately downstream of the combustor and a second turbine stage immediately downstream of the first turbine stage, the flow path assembly defining a flow path, the flow path assembly comprising:

• an inner wall defining an inner boundary of the flow path, the inner wall comprising an inner liner of the combustor;
• an outer wall defining an outer boundary of the flow path, the outer wall comprising an outer liner of the combustor;
• and
• a combustor dome positioned at a forward end of the combustor, the combustor dome including a body, an outer end extending radially to the outer wall, and an inner wing extending forward from the body along the inner wall,
• wherein a fastener extends through the inner wing and the inner wall to attach the combustor dome to the inner wall, and
• wherein the combustor dome is attached to only the inner wall.
