    Abstract: An apparatus for automating the fabrication of a copper vertical launch (CVL) within a printed circuit board (RGB) includes a feed mechanism to feed and extrude copper wire from a spool of copper wire and a wire cutting and gripping mechanism to receive copper wire from the feed mechanism, cut and secure a segment of copper wire, insert the segment of copper wire into a hole formed within the RGB, solder an end of the segment of copper wire to a signal trace of the RGB, and flush cut an opposite end of the segment of the copper wire to a surface of the RGB. The wire cutting and gripping mechanism includes a wire cutter to flush cut the segment of copper wire and an integrated heated gripper device to receive the copper wire from the spool of copper wire and cut and grab a segment from copper wire.

    Abstract: A process of fabricating an electromagnetic circuit includes providing three laminate sheets, forming a first feature in a first laminate sheet of the three laminate sheets, and forming a second feature in a second laminate sheet of the three laminate sheets. The second feature is aligned with the first feature when aligning the second laminate sheet with the first laminate sheet. The process further includes stacking the three laminate sheets so that the first laminate sheet is positioned above and aligned with the second laminate sheet and the second laminate sheet is positioned above and aligned with the third laminate sheet. The first feature and the second feature define a contiguous element. The process further includes filling the contiguous element with an electrically conductive material to form an electrically continuous conductor.

    Abstract: An apparatus includes a structure (100) configured to receive thermal energy and to reject the thermal energy into an external environment. The structure includes a lid (104) and a body (102). The structure also includes (i) multiple inline and interconnected thermomechanical regions (106-112) and (ii) one or more oscillating heat pipes (114a-114b) embedded in at least some of the thermomechanical regions. Different portions of at least one of the lid and the body form the thermomechanical regions. The one or more oscillating heat pipes are configured to transfer the thermal energy between different ones of the thermomechanical regions. At least one of the thermomechanical regions includes one or more shape-memory materials configured to cause a shape of the structure to change. Each of the one or more oscillating heat pipes includes at least one channel in the structure.

    Abstract: A system includes a flight vehicle (502, 602, 700) and one or more deployable radiators (504, 604, 702). Each deployable radiator includes a structure (100, 300) configured to receive thermal energy and to reject the thermal energy into an external environment. The structure includes (i) multiple inline and interconnected thermomechanical regions (102-108, 306-312) and (ii) one or more thermal energy transfer devices (202, 314a-314b) embedded in at least some of the thermomechanical regions. The one or more thermal energy transfer devices are configured to transfer the thermal energy between different ones of the thermomechanical regions. At least one of the thermomechanical regions includes one or more shape-memory materials configured to cause a shape of the structure to change. The thermomechanical regions may include one or more heat input regions (102, 306) configured to receive the thermal energy, one or more heat rejection regions (108, 312) configured to reject the thermal energy into the external environment, and one or more morphable regions (104, 308) including the one or more shape-memory materials and configured to change shape.

    Abstract: An apparatus includes multiple thermal actuator switches (100, 500, 700, 902-904, 1002-1004) configured to control a transfer of thermal energy. The thermal actuator switches are arranged in a stacked configuration. Each switch includes first and second plates (102-104, 502-504, 702-704) and a piston (108-110, 508-510, 708-710) movable between the plates. Each switch also includes a phase change material (112, 512, 712) configured to (i) expand to move a surface of the piston into a first position and (ii) contract to allow the surface of the piston to move into a second position. The surface of the piston thermally contacts the first plate and increases thermal energy transfer between the plates when in one of the first and second positions. The surface of the piston is spaced apart from the first plate and decreases thermal energy transfer between the plates when in another of the first and second positions. Different ones of the switches include different phase change materials that expand or contract at different temperatures.
