This paper describes all analytical and experimental activities (of NLR, prime contractor, and the subcontractors Bradford Engineering and Daimler Benz Aerospace-Space Infrastructure) to develop a high efficiency low pressure drop condenser and to bring it up to pre-qualifïcation level: - The inventory, dedicated to a literature review of potential concepts and means to improve condenser efficiency and to lower pressure drop, followed by a trade-off, supported by the necessary thermo-hydraulic analysis, yielding the definition of the design. - The manufacture of the condenser defined and the execution of an extensive test programme, performed under conditions reflecting, as close as possible, realistic in-orbit conditions. Thermo-hydraulic modelling was done to predict test results prior to the execution of the tests. The resulting condenser combines the high efficiency of a direct condensation annular configuration and the low pressure drop of a channelled configiuration, as it is shown in detail by results of performance and acceptance tests.
