Lightweight Carbon-Carbon High-Temperature Space Radiator

摘要

A document summarizes the development of a carbon-carbon composite radiator for dissipating waste heat from a spacecraft nuclear reactor. The radiator is to be bonded to metal heat pipes and to operate in conjunction with them at a temperature approximately between 500 and 1,000 K. A goal of this development is to reduce the average areal mass density of a radiator to about 2 kg/m~2 from the current value of ≈10 kg/m characteristic of spacecraft radiators made largely of metals.
