Transpiration Cooling Using Liquid Water

Abstract

At the German Aerospace Center (DLR), a possible solution for handling extreme aerothermodynamic heat loads
\nhas been investigated. The solution involves an innovative new way of transpiration cooling, using liquid water. The
\nconcept has been tested at the arc heated wind-tunnel section of DLR. The test campaign will be described and the
\nresults will be compared with transpiration cooling using a gas as a coolant.
