Abstract

The Institute for Flight Propulsion (LFA) of the Technische Universität München (TUM) operates a high pressure combustion facility, which serves as a testbed for injector element characterization, film and transpiration cooling as well as material compatibility tests both in national and international research programs. Especially tests to characterise film and transpiration cooling require efficient and stable combustion with minimum pressure oscillations in the chamber. During some test campaigns, the baseline injector showed increased HF pressure oscillations, which had not been observed during the commissioning of the injector in the past. A detailed analysis was performed identifying possible causes for the HF oscillations. Consequently, the possible mechanisms were investigated in a dedicated test campaign, leading to an optimized design of the injector.
