Abstract
The paper presents the work conducted by HPS GmbH on manufacturing, analysis and testing of an innovative CFRP radiator for spacecraft applications, having the same thermal performances and a mass reduction of more than 30 % compared to standard aluminum radiators (in addition see Schlitt et al. in 40th international conference on environmental systems, 2010). The developed configuration can be used as condenser or radiation heat sink on the East/West panels of the spacecraft for either two-phase or single-phase heat transportation systems.
