    Abstract: An attritable engine includes an engine case, which includes an outer wall and a fuel rail integral with the outer wall. The fuel rail includes a fuel line integral with the outer wall, a fuel ring configured to receive fuel from the fuel line, and an injector throat configured to receive aerated fuel from the fuel ring. The engine case includes counter distortion webbing defining the injector throat and is integral with the fuel rail and the outer wall. The engine case includes a combustion chamber configured to receive fuel from the injector throat.

    IPC: F01D5/28

    Abstract: An airfoil includes an airfoil body that has a trailing edge region. The trailing edge region includes first and second monolithic ceramic exterior walls, a flow discharge passage between the first and second monolithic ceramic exterior walls, a ceramic matrix composite (CMC) liner at least a portion of which is disposed in the flow discharge passage between the first and second monolithic ceramic exterior walls, and an array of pedestals disposed in the flow discharge passage. Each of the flow guides bridges the CMC liner and at least one of the first and second monolithic ceramic exterior walls.

    Abstract: An assembly for use in an attritable engine includes a hub and a blade. The hub is configured to rotate about a centerline axis passing through a center of the hub and is formed with a first type of layer-by-layer additive manufacturing process. The blade is connected to and extends radially outward from the hub. The blade is formed with a second type of layer-by-layer additive manufacturing process that is different than the first layer-by-layer additive manufacturing process. The hub and the blade are integrally formed together as a single piece of material with a layer-by-layer additive manufacturing process. The blade includes a root of a first material, a platform connected to the root, an airfoil connected to and extending from the platform, and a tip connected on a distal end of the airfoil opposite from the root. The platform includes a material that is different from the first.
