After a review of advanced radiator concepts, a rotating film radiator concept is analyzed to reduce the radiator mass in solar dynamic power systems. The concept envisions a rotating disk with a thin film of radiator liquid flowing radially outward while radiating directly to space. The radiator concept only utilizes currently existing technologies and overcomes containment problems faced by another concept, the rotating bubble membrane radiator (RBMR), which is also analyzed. A preliminary design suggests that the rotating film radiator can achieve a specific mass of 5.5 kg/kWt or 3.5 kg/m2.
