  • Publication number: 20240409238
    Abstract: A decision tool models emissions for a sustainable aircraft fuel (SAF) for the lifecycle of the fuel. The decision tool includes a controller module configured to receive data related to at least one fuel pathway for the fuel wherein the fuel pathway considers emissions from initial feedstock production to fuel burn during flight and arrival. The decision tool determines at least one fuel pathway for the fuel used to fuel the aircraft during a flight, models an emission score for the at least one fuel pathway, and then outputs the emission score where a user can purchase the fuel or make other decisions based upon the fuel pathway provided by the decision tool.

  • Patent number: 12129769
    Abstract: A method of forming an erosion shield for a turbine blade includes depositing a layer of filler material defining an upper surface. The method also includes depositing a layer of erosion-resistant material across the upper surface of the layer of filler material. An interface is defined between the layer of filler material and the layer of erosion-resistant material and has a shape of the upper surface. The method also includes machining the layer of filler material to produce the erosion shield. The erosion shield has the layer of erosion-resistant material, the machined layer of filler material, and the interface defined therebetween. An inner surface of the erosion shield is defined by the machined layer of filler material that is sized and shaped for attaching to a leading edge of the turbine blade. Each of the interface and the inner surface extend a length of the erosion shield.

  • Publication number: 20240229648
    Abstract: A method of manufacturing an erosion-shielded turbine blade includes providing a turbine blade for use with a rotary machine. The turbine blade includes an airfoil extending between a root and a tip. The airfoil includes a pressure side and an opposite suction side, and each of the pressure and suction sides extends between a leading edge and a trailing edge. The method also includes printing a green body part by an additive manufacturing process by selectively depositing a binder solution across a particulate erosion-resistant material, and sintering the green body part to produce a post-sintering erosion shield that includes densified erosion-resistant material. The method also includes coupling the erosion shield to the leading edge of the turbine blade.
