Systems, apparatus, articles of manufacture, and methods are disclosed to improve fan operability control using smart materials. An engine comprising an engine surface in an airflow path, a sensor positioned on the engine surface, and a smart-material-based feature positioned on the engine surface, the smart-material-based feature triggered to modify the airflow path when the sensor outputs an indication of a detected deviation from a reference value of an operating parameter of the engine.

Methods and apparatus to improve fan operability control using smart materials

A method for producing a component layer-by-layer include the steps of: depositing a layer of particulate material having a first area over a build platform; applying a radiant-energy-curable binder to the layer so that a selected portion of the first area is uniformly coated with binder; selectively curing a second area of the layer smaller than the selected portion of first area, using an application of radiant energy in a specific pattern that defines the geometry of a cross-sectional layer of the component; and repeating the steps of depositing, applying, and curing for a plurality of layers until the component is complete.

Selective curing additive manufacturing method

Pitch control assembly and propeller blade assembly having a spider hub are disclosed. The spider hub includes a hub and a set of arms spaced circumferentially about the hub and projecting radially from the hub, wherein the set of arms are configured to receive a set of blades such that a blade root of a blade is rotationally mountable into an arm included in the set of arms, a crosshead located within the hub and axially moveable relative to the hub, a torque tube located in the arm and extending into the hub, wherein a pitch angle of the blade can be adjusted by axially moving the crosshead to rotate the torque tube to effect a corresponding rotation of the blade.

Pitch control assembly and propeller assembly and method of adjusting pitch

Hub assembly and propeller blade assemblies incorporating partial hub assembly having a backing plate with a set of partial root seats and a set of clamps selectively operably couplable to the backing plate with each clamp defining a second partial root seat and wherein when a clamp is coupled to the backing plate a root seat is formed, propeller blades having roots are received within the root seats.

Hub assembly and propeller assemblies

Propeller blade assemblies and a propeller blade retention assembly including a sleeve for operably coupling a propeller blade to a hub wherein the sleeve retains the propeller blade within the hub and allows the propeller blade to rotate about its pitch axis and where the sleeve includes a self-aligning mechanism.
