Abstract
Cooling experiments are performed by DLR Institute of Space Propulsion, applying a transpiration cooling system to a scramjet model combustion chamber. Nitrogen coolant is injected through different porous wall samples made of sintered stainless steel into a Mach 2.5 hot gas main flow. Different inlet conditions as well as the response of the transpiration cooling to a shock impingement caused by a 9.3° half wedge are investigated. Results show good cooling efficiency of the transpiration cooling which is not affected much by the impinging shock. A comparison with common theoretical cooling models shows their limited applicability to measurements downstream of the porous section.
