Stagnating Radiators

The Controlled Stagnation Radiator offers the ideal combination of maximized radiator performance at high heat loads and a high turndown ratio via controlled, determinate stagnation at low heat loads by adding passive pressure balancing devices which provide local stagnation resistance.  This allows a radiator optimized for full flow performance to exhibit determinate deep stagnation for high turndowns, as well as in intermediate loads, as is required of modern spacecraft thermal control system design.
