  • Patent number: 10752557
    Abstract: A means for attaching a metallic component to a non-metallic component using a compliant material having thermal properties intermediate those of the metallic component to a non-metallic component is provided. The method can accommodate CTE mismatches and wear-type problems common to many assemblies of dissimilar materials. In particular, the method provides a sufficient wear surface to accommodate relative motion and provide a durable wear surface that does not excessively wear/gall/mico-weld itself together and provides the necessary damping and motion for proper operation in aeronautical applications.

  • Patent number: 10500633
    Abstract: A method of manufacturing an airfoil includes the steps of depositing multiple layers of powdered metal onto one another. The layers are joined to one another with reference to CAD data relating to a particular cross-section of an airfoil. The airfoil is produced with leading and trailing edges joined by spaced apart pressure and suction sides to provide an exterior airfoil surface. An exterior wall provides the exterior airfoil surface at the leading edge. An impingement wall is integrally formed with the exterior wall to provide an impingement cavity between the exterior wall and the impingement wall. Multiple impingement holes are provided in the impingement wall. The impingement holes are spaced laterally across the impingement wall.

  • Patent number: 9770866
    Abstract: An example multi-dimensional component building system includes a first chamber having at least one base disposed therein, a second chamber adjacent to and in fluid communication with the first chamber through a first door, and a third chamber adjacent to and in fluid communication with the second chamber through a second door. The second chamber is fluidly sealed from the first chamber if the first door is in a closed position. The second chamber is configured to receive the at least one base via a first transfer mechanism if the fluid parameters of the first chamber are approximately equal to the fluid parameters of the second chamber. The second chamber includes a directed heat source and a build-up material configured to form a component on the at least one base by melting or sintering.

  • Publication number: 20170184120
    Abstract: An airfoil includes an airfoil body including a first side wall and a second side wall that is spaced apart from the first side wall. A longitudinally elongated rib connects the first side wall and the second side wall and divides a cavity into a forward section and an aft section. The longitudinally elongated rib includes at least one opening fluidly connecting the forward section and the aft section of the cavity. The opening is located in a lateral central portion of the longitudinally elongated rib with regard to the longitudinal axis such that first and second sections of the longitudinally elongated rib bound respective lateral sides of the at least one opening. The opening defines a maximum dimension along a direction perpendicular to the longitudinal axis. The maximum dimension is greater than a minimum dimension of each of the first and second sections in the same direction.

  • Patent number: 9404369
    Abstract: An airfoil includes an airfoil body that defines a longitudinal axis. The airfoil body includes a leading edge and a trailing edge and a first side wall and a second side wall that is spaced apart from the first side wall to define a camber line there between. The first side wall and the second side wall join the leading edge and the trailing edge and at least partially define a cavity in the airfoil body. Multiple ribs extend longitudinally in the cavity and are laterally spaced apart from each other relative to the longitudinal axis. In at least one plane that is perpendicular to the longitudinal axis, each of the ribs connects the first side wall and the second side wall along respective minimum distance directions that are perpendicular to the camber line. At least two of the respective minimum distance directions are non-parallel.
