A method of forming a material using a supersonic fluidic oscillator in a superplastic forming process and a related system is provided. The method comprises applying pressurized gas at a baseline pressure to a surface of the material when the material is received within a cavity of a forming tool, and creating pressure fluctuations with a supersonic fluidic oscillator relative to the baseline pressure within the tool cavity. Each pressure fluctuation (i) deforms the material and (ii) subsequently allowing for a partial stress relief of the material during the forming process.

The present disclosure relates to an assembly for formation of a fan blade. The assembly comprises a suction panel; a pressure panel; and a membrane having a leading edge and a trailing edge. The membrane is sandwiched between the suction panel and pressure panel. The membrane comprises a gas entry slot extending in a radial direction, the gas entry slot having a radially outer receiving portion for receiving a pipe, and a radially inner portion. The radially inner portion of the gas entry slot has a substantially uniform width in a direction between the leading and trailing edge of the membrane.

An article comprising a bulk metallic glass skin having one or more functional features integrated therein is described and a method of forming the same is described. The one or more functional features exhibit a variation in stiffness between the one or more functional features and the bulk metallic glass skin that is defined by an applied force over an achieved deformation. The stiffness of each of the one or more functional features is at least 1000 times less than an average stiffness of the bulk metallic glass skin.

An apparatus for forming a panel, including a first face sheet, a second face sheet and a core sheet between the first face sheet and the second face sheet, may include a molding tool defining a forming cavity shaped to correspond to the panel, a heating system positioned adjacent to the forming cavity and configured to heat the forming cavity, and a pressurization system configured to pressurize a cavity volume between the tool and the panel and pressurize a panel volume between the first face sheet and the second face sheet.

Examples of forming metal composites are described herein. In an example, a metal sheet is formed into a predetermined shape using superplastic thermal forming technique. Further, a carbon fiber-reinforced polymer sheet is shaped into the predetermined shape by thermal forming. The metal sheet and the carbon fiber-reinforced polymer sheet are coupled by applying an adhesive between the metal sheet and the carbon fiber-reinforced polymer sheet, to form a metal composite.
