A stiffened panel comprises a composite panel, and a stiffener including a base flange on the composite panel. The base flange is tapered towards the panel. The stiffened panel further comprises a composite overwrap layer on only the composite panel and a tapered surface of the base flange.

Stiffened composite panels

A method for working a component to reduce a propensity for advanced dynamic change analyzes affects of a StressWave process on at least one location on a size and shape of the component. The component is also analyzed as to the affects of adding at least one feature on a size and shape of the component. A beginning shape of the component is then extrapolated.

Manufacturing process for extending a length of service of component parts

Methods of fabricating electromagnet assemblies are disclosed. In one embodiment, a includes forming a first helix and a second helix, each helix having a first end and a second end and a substantially oval cross-section, the cross-section having a major axis, each helix being configured to concentrate electromagnetic flux at a midpoint on the major axis. Each helix is bent at an angle and offset from the major axis, resulting in a first planar surface including the major axis and a second planar surface. The first and second helixes are oriented such that the outer edges of the respective second planar surfaces coincide and the outer edges of the respective first planar surfaces are in diametric opposition. The first and second helixes are affixed by their respective second planar surfaces, and electrically connected by their respective second ends.

Layered wing coil for an electromagnetic dent remover

An electromagnet assembly for supplying a region of concentrated electromagnetic flux is provided. The assembly includes a flat strip of an electrically conductive metal. The strip has a first and a second opposite planar surfaces at least one of which is covered by a dielectric material. The strip has first and second end portions. The strip is wound in a coil including at least one first loop and one second loop and disposing the second opposite planar surface in the first loop substantially-adjacent the first opposite planar surface in the second loop. The coil is disposed about an axis of symmetry configured to concentrate electromagnetic flux at a midpoint on the axis of symmetry. First and second electrical terminals are connected at the first and second end portions, respectively.

A power supply for an electromagnetic force system comprising a slow current pulse system in parallel with a dumping circuit feeding a blocking inductor in parallel with a series of diodes; a fast current pulse system of opposing polarity and parallel to the slow current pulse system and blocking inductor, the fast pulse system including a triggered vacuum spark-gap for discharging the fast current pulse system through a working coil such that the current through the coil decreases rapidly and the magnetic field in the gap decreases substantially while the magnetic field in and behind the work piece decreases only slightly, resulting in a large field gradient across the work piece and the creation of a pulse of tension force on the work piece.

Electromagnetic dent remover power supply

A chip breaker drill bushing assembly (11) for a fluted drill bit (37) is disclosed. The assembly comprises a drill bushing housing (13) and a sleeve (15). The drill busing housing (13) includes a body (17) and an outwardly protruding guide shaft (19). The guide shaft has a smooth end (31) for tightly contacting the surface of a work piece (63) to be drilled. The sleeve (15) is located in the body (17) of the housing (13), in alignment with the guide shaft. The end of the sleeve (15) facing the tip (29) of the guide shaft (19) includes a chip breaker (41). The chip breaker (41) includes two spaced-apart teeth (46a, 46b) that are defined by two helical troughs (47a, 47b) that protrude into the sleeve (15). The two helical troughs (47a, 47b) are aligned with two longitudinal apertures (33) in the outwardly protruding guide shaft (19).
