Experimental Investigation of Self-Excited Combustion Instabilities in a LOX/LNG Rocket Combustor
Get PDFTwo types of combustion instabilities were observed in a multi-injector research combustor with LOX/LNG propellants operating at conditions similar to an upper stage rocket engine. The first was identified as an excited tangential acoustic mode of the combustion chamber and can be explained by coupling with the LOX injectors, similar to the mechanism previously observed in tests with LOX/H2 propellants. The other type is characterized by longitudinal acoustic oscillations with amplitudes of at least 20% of the mean chamber pressure. Analysis of the test data suggests that flashback of a lifted flame is likely to be the trigger mechanism for the second type of instabilities
