Abstract: A method is provided for forming an annular object. This method includes: providing a frustoconical preform extending axially along an axis, wherein a sidewall of the frustoconical preform is angularly offset from the axis by a preform angle; externally drawing the frustoconical preform over an outer surface of a punch and an outer surface of a die clamp to provide an externally drawn body, wherein the outer surface of the die clamp is angularly offset from the axis by a die clamp angle that is different than the preform angle; mating a die with the die clamp to provide a die assembly, wherein the externally drawn body is clamped radially between the die and the die clamp; and translating the die assembly axially along the axis and into a bore of the punch to at least partially internally draw the externally drawn body against an inner surface of the punch.

Abstract: An apparatus for forming a nacelle leading edge includes an actuation assembly, a punch, and a die. The punch is in communication with the actuation assembly and annularly disposed about a first axis. The punch is configured to mate with an interior surface of a preform. The die is in communication with the actuation assembly and disposed within the first axis. The die is configured to retain an exterior surface of the preform. The actuation assembly is configured to effect relative motion between the punch and the preform. The actuation assembly is configured to offset the punch so that the punch is annularly disposed about a second axis, different than the first axis.

Abstract: Aspects of the disclosure are directed to a bonding of a first skin and a second skin to a core material, coupling a sheet to the first skin to form with the first skin an enclosure containing the second skin and the core material, exposing the first skin, the second skin, and the core material to heat, and based on the exposition of heat, applying pressure via the enclosure to the first skin to cause the first skin to deform and expand to a shape of a die.
