摘要： Duct assembly and method of forming a duct assembly, the method including providing a preform having a unitary body with multiple sleeve sections defining multiple apertures, disposing multiple sacrificial mandrel pieces adjacent the preform body such that at least one of the multiple sacrificial mandrel pieces abuts at least one of the multiple sleeve sections, and forming the duct assembly to define a unitary metallic tubular element.

摘要： A turbine engine with a casing including opposing surfaces and a manifold opening passing through the surfaces. A surface cooler is provided adjacent one of the surfaces. A cooler manifold passes through the manifold opening. A seal is provided between the surface cooler and the casing. At least one bolt is used to secure the surface cooler to the casing with the seal in between.

摘要： A method of forming a tubular element includes providing an attachment joint, and disposing a mandrel adjacent the attachment joint, where the mandrel can also include an outer or exposed surface. Metal can be disposed on the outer surface of the mandrel to form at least a portion of the tubular element.
