Additively manufactured hinge assembly

Abstract:

A hinge assembly and a method of additively manufacturing the same are provided. The hinge assembly includes a hub defining a body and a first mounting arm and a second mounting arm each projecting from the body. The first mounting arm and the second mounting arm are spaced from one another and define a hinge axis. The hinge assembly also includes a rotatable member or vane rotatably coupled with the hub and positioned between the first mounting arm and the second mounting arm. The rotatable member defines a vane hinge member or hinge member having a first nesting feature shaped complementary to a portion the first mounting arm and a second nesting feature shaped complementary to a portion of the second mounting arm of the hub to nest the hinge member between the first mounting arm and the second mounting arm. The hub and the rotatable member are simultaneously additively manufactured as distinct, but inseparable monolithic components.
