Abstract: The design of an Advanced Ceramic Fabric (ACF) thermal management device for use in both interplanetary and near-earth space must consider several important aspects of the environment. First, the radiation field at various locations is dominated by a proton component which deposits its energy on the surface of the device. Second, various liner materials must be compatible with the working fluids selected for the system. Third, the fluid dynamics and heat transfer characteristics of this device should be adequately characterized. With the selection of materials that are compatible with the operating environment, the Bubble Membrane Radiator (BMR) which uses ACF materials, may be utilized for several future space missions.
