Kurzfassung
High frequency combustion instabilities in liquid propellant rocket engines are investigated using a subscale rocket engine with the propellant combination hydrogen/oxygen at representative conditions. It has been demonstrated in previous test runs with this combustion chamber that it shows self-excited high frequency combustion instabilities at specific operating conditions with gaseous hydrogen at a temperature of 115 K. In order to investigate the effect of the hydrogen temperature, this analysis has been expanded to test runs with liquid hydrogen. It is shown that the hydrogen temperature has a significant influence on the acoustic behaviour of the combustion chamber and therefore on the observed instabilities.
