Method and apparatus for hot forming metal parts
A metal part is hot formed by placing a metal part blank on a forming tool and installing a fabric cover over the forming tool, overlying the metal part blank. The fabric is at least partially wrapped around the metal part blank. The metal part blank is heated to a temperature sufficient to allow forming of the metal part blank. Forming pressure is applied to the metal part blank that conforms the metal part blank to the forming tool by tensioning the fabric.
Air management of honeycomb composite inserts
A fastener assembly includes a base which defines a bore which extends through the base. The fastener assembly further includes a receptacle wherein the receptacle includes a sidewall wherein the sidewall defines a channel which extends through the receptacle. The channel extends from a first opening defined by the sidewall to a second opening defined by the sidewall and the sidewall is connected to the base wherein the second opening aligns with the bore of the base. The sidewall of the receptacle defines a vent opening which extends through the sidewall. The receptacle and the base define a flow path through the vent opening of the sidewall, through the channel of the receptacle, through the second opening of the sidewall of the receptacle and through the bore of the base.

Method for spin forming lipskins
Method of manufacturing of components used in the field of aviation aircraft and, specifically, an aircraft engine nacelle lipskin. Instead of spinning flat plates, this method uses spinning a cylinder, thus eliminating waste material. It also eliminates the need for rivet lines which results in better laminar flow. Further, there is a reduction of other costs in addition to reducing drag.

Vacuum forming method
A method for forming large titanium parts includes forming bends into a titanium plate for form a bent part. The bent part is then roll-formed to form contours into the bent part. The surfaces of the contoured part are rough-machined, and the part is then secured to a bladed form fixture. The bladed form fixture comprises a plurality of header boards that secure the part to the fixture. The fixture part is placed in a thermal vacuum furnace and a stress-relieving operation is performed. The part is removed from the fixture and final machining takes place.

METHOD FOR FORMING AND HEAT TREATING NEAR NET SHAPE COMPLEX STRUCTURES FROM SHEET METAL
A method of manufacturing a complex-shaped metal part, including the steps of applying a metallic sheath around a sheet metal workpiece and applying an electric current through the workpiece in the metallic sheath to heat the workpiece. The method also includes shaping the workpiece in the metallic sheath into a complex-shaped metal part while it is being heated. The shaping can be performed between two ceramic dies or using other techniques for forming complex shapes and curvatures into the workpiece. The method then may include cooling the complex-shaped metal part and removing the metallic sheath from the complex-shaped metal part. This method can allow reactive and refractory material to be safely heated without oxidation when heating/forming in air when the workpiece is sealed within a sacrificial stainless steel or nickel alloy envelope to protect the enclosed workpiece.
METHOD FOR MANUFACTURING A BEAM WITH CLOSED SECTION
A method for manufacturing a beam (P1, P2) with closed section, the beam being produced by combining a first profile (P10, P20) and a second profile (P11, P21), including the following steps: producing the first profile by a first stamping of a first plate (5, 50) between a first punch (1, 10) having a first imprint and a second punch (2, 20) having a second imprint and incorporating a core (3, 30) modifying its second imprint; holding the first profile (P10, P20) on the first punch and positioning the core (3, 30) above the first profile (P10, P20); producing the second profile (P11, P21) by a second stamping of a second plate (6, 60) against the core (3, 30) between the first punch (2, 20) and the assembly formed by the superposition of the first punch (1, 10), the first profile (P10, P20) and the core.
Stretch forming method for a sheet metal skin with convex and concave curvatures
A method of forming sheet metal skins of the inner fixed structure of a blocker door thrust reverser assembly having convex and concave curvatures. The method includes plastically stretching a sheet of metal about a mandrel having a chordwise central first axis to form a substantially convex shape. The method further includes the addition of features after the substantially convex shape is formed to facilitate plastically stretching a portion or portions of the substantially convex shape into a substantially concave shape about an axis that is substantially parallel to the chordwise central first axis.
