Kurzfassung
In the arc heated facility LBK a transpiration cooling concept based on porous CMC material was qualified for application in external hypersonic flow, in particular for atmospheric entry. The experimental setup allowed a direct comparison of the thermal behaviour of transpiration cooling to a well-qualified passive thermal protection technology. Tests were performed for different coolants at various flow rates in order to identify the influence on cooling efficiency. Nitrogen, argon and helium were used as coolants. It was found that for a given configuration there is an optimal coolant flow rate for each coolant. These optimal coolant flow rates could be identified and compared for all coolants used.
