This paper describes advanced heat acquisition and transport components developed and tested as part of the Two-Phase Survivable Thermal Management (TSTM) Program. The components are: a pumped heat pipe coldplate capable of removing very high-flux waste heat loads with a minimum temperature drop; and a thermal transport system designed to transport large quantities of waste heat over large distances with a long life and low power consumption. These components are intended for use in an advanced thermal control system which removes waste heat from high-power spacecraft. For the heat acquisition component, a successful design development phase was completed, resulting in a producible design which met program goals. This design was subjected to extensive tests to demonstrate performance under a wide variety of conditions. The component was found to perform in a predictable manner. Measured overall component thermal conductance was 4.0 W/cm2/°C for fluxes up to 60 W/cm2.
