摘要： The system and method of the present application can include machining complex part features in a flat metal sheet (401), and subsequently forming the machined flat metal sheet to have the desired shape and contours. Prior to the step (303) of machining the complex part features, the method can include (311) calculating a scaled location of the complex part features so that the subsequent forming step (305) acts to translate and deform the complex part features into a desired location.

摘要： To protect an article with an aerodynamic surface, such as an aeroplane propeller or helicopter rotor, from erosive damage caused by flying particulate matter, a thin elastomeric protective covering is provided. This layer covers approximately 15% of a forward face ( 15 ) a leading edge ( 12 ), and approximately 90% of the rear face ( 13 ) of the article. Typically, it is made of polyurethane with hardness between 85 Shore A and 80 Shore D. It is applied by centrifugal casting using a silane log gammaglycidoxporpyl-tri-methoxysilane as a coupling agent when bonding to a metal surface such as aluminum.

摘要： A sheath (12) for covering and protecting a component leading edge of an airfoiled component is disclosed The sheath includes a sheath leading edge (14), and a first protective side (16) and a second protective side (18), wherein the first and second protective sides (16,18) are merged at the sheath leading edge (14). A cavity (20) is formed between the first and second protective sides (16,18), wherein the cavity (20) is adapted to have the airfoiled component positioned therein and engage an inside surface of each of the first and second protective sides (16,18). The sheath (12) is formed from a material including cobalt, and preferably a nickel-cobalt composition. Preferred embodiments include cobalt in the nickel-cobalt composition present between 8-32wt.% and 30-54wt.%, based on the weight of the sheath. An airfoiled component construction is also disclosed. This construction includes a main structural component formed in the shape of an airfoil, wherein the main structural component has a leading edge (14), and a sheath covering and protecting the leading edge (14), wherein the sheath is formed from a material including cobalt such as a nickel-cobalt composition. Preferred embodiments include cobalt in the nickel-cobalt composition present between 8-32wt.% and 30-54wt.%, based on the weight of the sheath.

摘要： A fan blade (52) includes a lattice structure (80), a fill (82), and a structural wrap (84). The lattice structure (80) defines an airfoil body (110) that has a cavity (116). The lattice structure (80) defines at least one spar (106) that extends radially from a root (60) of the airfoil body (110) towards a tip (78) of the airfoil body (110). The fill (82) is disposed within the cavity (116). The structural wrap (84) is disposed about the lattice structure (80). The structural wrap (84) defines a plurality of plies (120) that extend from a leading edge (70) of the airfoil body (110) towards a trailing edge (72) of the airfoil body (110).
