NASA has numerous requirements for in-space repair capabilities to aid future missions beyond earth orbit. A subset of these requirements is adhesive patch materials that provide permanent or temporary repair of a wide variety of surfaces with minimal surface preparation and that can operate in the space environment. This work will result in the production of a repair kit for in-space applicatio ...

This Small Business Innovation Research project will develop Pressure Controlled Heat Pipes (PCHPs) for precise temperature control (milli-Kelvin level). Several optical systems, lasers, and detectors require tight temperature control to better than +/-1K. Some new missions even desire temperature control and thermal gradient control to the milli-Kelvin level. Typically precision temperature co ...

The overall program objective is to develop a high temperature variable conductance heat pipe (VCHP) backup radiator, and integrate it into a Stirling radioisotope power system. A VCHP is similar to a heat pipe, but has a reservoir and a controlled amount of non-condensable gas (NCG) inside the reservoir. At low power, most of the condenser is blocked by the NCG. As the power increases, more and ...
