Abstract
An assembly is provided for a gas turbine engine. This gas turbine engine assembly includes a stationary engine structure. The stationary engine structure includes a diffuser, a combustor, an engine case and a plenum. The combustor is disposed within the plenum. The engine case forms a peripheral boundary of the plenum. A gas path extends sequentially through the diffuser, the plenum and the combustor. A first section of the stationary engine structure is formed as a first monolithic body. The first section includes the diffuser and the combustor. A second section of the stationary structure is formed as a second monolithic body. The second section is configured as or otherwise includes the engine case.
Claims15
A manufacturing method, comprising:
- forming an engine structure preform including a first section preform and a second section preform formed integral with the first section preform, the first section preform including a diffuser and a combustor, and the second section preform comprising an engine case;
- separating the first section preform from the second section preform to respectively provide a first section and a second section that is discrete from the first section;
- and
- attaching the second section to the first section to provide an engine structure, the combustor disposed within a plenum of the engine structure, the engine case forming a peripheral boundary of the plenum, and a gas path extending sequentially through the diffuser, the plenum and the combustor.
