Embodiment Construction

[0023] Reference will now be made in detail to present embodiments of the invention, one or more examples of which are illustrated in the accompanying drawings. The detailed description uses numerical and letter designations to refer to features in the drawings. The same or similar reference numerals in the drawings and description have been used to refer to the same or similar parts of the present invention. As used herein, the terms "first," "second," and "third" are used interchangeably to distinguish one element from another and are not intended to indicate the position or importance of the various elements. The terms "forward" and "aft" refer to relative locations within a gas turbine engine, with forward referring to a location closer to the engine inlet and aft referring to a location closer to the engine nozzle or exhaust. The terms "upstream" and "downstream" refer to relative directions with respect to fluid flow in a fluid path. For example, "upstream" refers to t...

Abstract

A combustor assembly (80) for a gas turbine engine (10) is provided. The combustor assembly (80) generally includes a liner (82, 84) at least partially defining a combustion chamber (88) and having an inner wall (132) defining an inner opening (140) and an outer wall (134) defining an outer opening (142). A boss (152) is defined by the inner wall (132) and extends around the inner opening (140) toward the outer wall (134). A body (160) of a ferrule (144) extends along an axial direction (A2) through the outer opening (142) and defines a central bore (162) in fluid communication with the combustion chamber (88). A radial flange (164) extends from the body (160) along a radial direction (R2) and is positioned between the inner wall (132) and the outer wall (134). The flange (164) defines a flange diameter (166) that is greater than an internal diameter (150) of the outer opening (142) such that the ferrule (144) may slide along the radial direction (R2) but is restrained in the axial direction (A2).

Description

technical field [0001] The subject matter relates generally to gas turbine engines, or, more specifically, to combustor assemblies of gas turbine engines. Background technique [0002] A gas turbine engine typically includes a fan and a core arranged in flow communication with each other. Additionally, the core of a gas turbine engine typically includes a compressor section, a combustion section, a turbine section, and an exhaust section in a serial flow order. In operation, air is provided from a fan to the inlet of the compressor section where one or more axial compressors progressively compress the air until it reaches the combustion section. Fuel is mixed with compressed air and combusted in the combustion section to provide combustion gases. Combustion gases are directed from the combustion section to the turbine section. The turbine section is driven by a flow of combustion gases through the turbine section, which is then directed through an exhaust section, eg, to ...
