Patent Primary Examiner
A radiator system uses an innovative passive control scheme in combination with dependable mechanical design features to meet or exceed the requirements for orbital applications. The disclosed radiator system is unique because we target an extremely high turndown ratio of 200:1 with an entirely passive two-phase pumped loop using ammonia as the working fluid. Sections of the radiator will selectively freeze to assist the turndown, and the mechanical design of the radiator can handle the high pressures experienced during such freezing and thawing events.
