Two-Phase Thermal Control for Planetary Base and Surface Systems Applications: A Critical Review of Some Research Issues to be Investigated 2008-01-2006

Discussed are some critical theoretical and experimental research issues to be investigated for candidate two-phase thermal control systems (and their components), to define what is to be done to develop reliable systems, for near and far future planetary applications envisaged. An earlier publication SAE-2007-01-3242 (“Design of planetary two-phase thermal control systems, using experimental data of terrestrial model systems, built according to thermal-gravitational modelling and scaling laws”), discussed that such advanced thermal control systems are one of the key technologies needed for future applications within the framework of the NASA Authorization Act 2005. This act specifies a programme to be established to develop sustained human presence on the Moon, including a robust pre-curser programme to promote exploration, science, commerce and US preeminence in space, also as a stepping stone to future exploration of Mars and other planetary destinations. Results of this publication are briefly summarised, and made more complete. Also additional interesting thermal issues are added. This altogether results in a possible, long-term research roadmap.
