Experimental and Numerical Study of a Supersonic Combustion Chamber with Different Two-Staged Injection Concepts

Abstract

to perform and ight tests are rather expensive. Numerical studies are, therefore, often used to perform parameter studies within the relevant Mach number regime. Nevertheless, systematic experimental data are absolutely essential when validating numerical studies. The present study focuses on a two-staged supersonic combustion chamber and hereby joins numerical studies with experimental validation and investigation. Previous studies with a two-staged combustor have proven to have essential advantages compared to the single-staged design. Investigations with the single-staged central injector concept at the Institute of Aerospace Thermodynamics (ITLR), Univer
