Abstract: A method is provided that uses half-period translations, ply-upon-pin repositions, and shape-maintaining pins with a bolster plate, with insertable nodal heating elements that provide heat at their rectangular ends and when driven under pressure against opposing pins with rectangular faces cure portions of a pre-impregnated fabric to make honeycomb core composite articles.

Abstract: An electrical component and a method of constructing it are disclosed. The component includes a hollow tubular structure. The structure includes a series of axially spaced apart rings and at least one outer perimeter housing member. The housing member interconnects the rings for defining an internal configuration of the hollow tubular structure for electrical purposes. The rings and the housing member each include inter-engageable elements for helping secure mechanically the rings and housing member together to facilitate final assembly of the electrical component.

Abstract: A low profile non-resonant traveling wave slot antenna operating over broad frequency bands is in the form of a multiple layer circuit, which includes a generally planar slotted conductor sheet having an open smoothly curved tapered planar slot therein and a three-dimensionally smoothly curved stripline conductor sheet having an elongated stem portion electrically connected at its distal end to a feed point on top of the slotted conductor sheet and extending downwardly through the slot therein and terminating in an enlarged smoothly tapered portion to transition the characteristic impedance between the feed point and an aperture impedance matched to free space.

Abstract: The invention relates to high stiffness parabolic structures utilizing integral reinforced grids. The parabolic structures implement the use of isogrid structures which incorporate unique and efficient orthotropic patterns for efficient stiffness and structural stability.

Abstract: A composite structure and method for constructing same for use in fabricating the framework of a spacecraft is disclosed. The structure is cut from flat sheets of composite laminate materials, and then assembled. The use of tenons and mortises provides for self-fixturing and adhesive bonding of the structural components.

Abstract: A composite antenna and method for constructing same is disclosed. The composite antenna has a grid comprised of electrical conductors woven into the warp of a resin reinforced cloth forming one layer of the multi-layer laminate structure of the antenna.

Abstract: A guide rail assembly for clamping circuit boards in place comprising a guide rail directly attached to a heat radiating fin formed from a graphite fiber reinforced plastic. The fins have tenons that fit within the guide rail to provide additional resistance to clamping forces. The guide rail assembly can be assembled using a variety of bonding methods, including adhesives.
