A heat rejection system includes a plurality of panel subassemblies and a solid state heat pipe flex joint. Each panel subassembly includes a fin, a solid state heat pipe manifold, a first solid state heat pipe tube operatively connected to the solid state heat pipe manifold and secured to the fin, a second solid state heat pipe tube operatively connected to the solid state heat pipe manifold adjacent to the first solid state heat pipe and secured to the fin. The solid state heat pipe flex joint operably connects the solid state heat pipe manifolds of two of the plurality of panel subassemblies in a hermetically sealed configuration, and is configured to permit repositioning of the two panel subassemblies relative to each other.

Solid state heat pipe heat rejection system for space power systems

A solar receiver device includes a metal conduit and a glass container disposed around the metal conduit such that there is a space between the glass container and the conduit. A coating is disposed on the metal conduit and has a composition that includes at least one element from silicon, titanium, aluminum, barium, and samarium.

Solar receiver and solar power system having coated conduit

An apparatus is provided and includes a reactor core, a boom and a shield assembly supportively interposed between the reactor core and the boom, a heat pipe disposed in thermal communication with the reactor core, a thermoelectric power converter operably coupled to the heat pipe, struts supportively coupled to the heat pipe at opposite ends of the power converter and hinge joints to rotatably couple the struts to the boom, at least one of the hinge joints being spring-loaded.

Thermoelectric power converter support structure

A method of forming a nanocomposite thermoelectric material having microstructural stability at temperatures greater than 1,000&#xb0; C. The method includes creating nanocrystalline powder by cryomilling. The method is particularly useful in forming SiGe alloy powder.

High temperature stable nanocrystalline SiGe thermoelectric material

A thermal expansion compensator is provided and includes a first electrode structure having a first surface, a second electrode structure having a second surface facing the first surface and an elastic element bonded to the first and second surfaces and including a conductive element by which the first and second electrode structures electrically and/or thermally communicate, the conductive element having a length that is not substantially longer than a distance between the first and second surfaces.
