Selected Supersonic Combustion Activities at DLR within the European LAPCAT Project

Kurzfassung

Within the LAPCAT project the working areas of the DLR Institute of Space Propulsion at Lampoldshausen and of the DLR Institute of Aerodynamics and Flow Technology at Göttingen/Braunschweig are focussed on basic experimental and numerical investigations of scramjet combustor processes with regard to the engine development for a proposed Mach 8 long distance cruise plane. The present paper gives an overview of the conducted work and the results, which have been obtained up to now. They cover the investigation of the performance characteristics of single injectors with different outer shapes with regard to mixing and combustion enhancement in a connected tube facility and experimental and numerical investigations of the performance characteristics of a complete scramjet flight test configuration consisting of intake, combustor and exhaust in a free jet ground based test facility.
