Feb 3, 2021

Appl. No.:

17/166223

Inventors:

- Schenectady NY, US
Joel Primmer White - Cincinnati OH, US
Gregory Scott Phelps - Cincinnati OH, US
Darrell Glenn Senile - Oxford OH, US
Tyler Lucas Walker - Newark DE, US

International Classification:

B30B 11/02

Abstract:

Compaction systems and methods of compacting components are provided. In one aspect, a laminate of a component can be laid up on a tool of a compaction system. The laminate defines a cavity. A noodle is positioned relative to or in the cavity. A noodle ring is then positioned relative to the noodle. For instance, the noodle ring can be placed over the noodle. A cross section of the noodle ring can be shaped complementary to a cross section of the noodle. A plunger of the compaction system is moved so that it engages the noodle ring. Particularly, the plunger is moved in such a way that a force is applied on the noodle ring so that the noodle ring compacts the noodle into the cavity.

International Classification:

F23R 3/00
F23R 3/60

Abstract:

A combustor assembly for a gas turbine engine includes a dome having a forward surface and an inner surface. The forward surface and the inner surface of the dome at least partially define a slot. The combustor assembly also includes a liner at least partially defining a combustion chamber and extending between an aft end and a forward end. The forward end of the liner is positioned within the slot of the dome. The forward end of the liner includes an axial interface surface and a radial interface surface. The axial interface surface defines a radial gap with the inner surface of the dome and the radial interface surface defines an axial gap with the forward surface of the dome. At least one of the radial gap or the axial gap is less than about 0.150 inches during operating conditions of the combustor assembly to prevent an undesirable airflow.

Abstract:

Composite components having a T or L-shaped configuration that include features that reduce void defects between abutting laminate portions and provide improved mechanical properties are provided. Methods for forming such components are also provided. In one exemplary aspect, a composite component defines a first direction and a second direction and includes a wedged-shaped noodle at a joint interface between an abutting first laminate portion extending along the first direction and a second laminate portion extending along the second direction. The noodle has a first surface that is angled with respect to the second direction. At least one of the plies of the second laminate portion terminate and attach to the angled first surface of the noodle.

International Classification:

F23R 3/28
F23R 3/60

Abstract:

Components and methods for forming components are provided. For example, a method for forming a component includes laying up a plurality of plies to form a component preform that defines an axis of symmetry and a circumferential direction. Laying up the plurality of plies includes overlapping ends of the plurality of plies to define overlap regions and offsetting the overlap regions along the circumferential direction such that any radial line drawn from the axis of symmetry through the plies passes through only one overlap region. In another embodiment, a component includes a body that is symmetric about an axis of symmetry and that defines a circumferential direction and a radial direction. The body is formed from a plurality of plies and has a substantially uniform thickness. Ends of the plurality of plies are overlapped to define a plurality of overlap regions, which are offset along the circumferential direction.

International Classification:

F01D 9/02
F01D 25/24

Abstract:

Nozzles and nozzle assemblies for gas turbine engines are provided. A nozzle includes an airfoil having an exterior surface defining a pressure side and a suction side extending between a leading edge and a trailing edge, an outer band disposed radially outward of the airfoil, the outer band including a radially outwardly-facing end surface, and an inner band disposed radially inward of the airfoil, the inner band including a radially inwardly-facing end surface. The nozzle further includes a flange extending radially from one of the radially outwardly-facing end surface or the radially inwardly-facing end surface. The flange is formed from a ceramic matrix composite material and includes a plurality of ceramic matrix composite plies stacked together and generally having an L-shape in a circumferential cross-sectional view.
