Research output: Chapter in Book/Report/Conference proceedingConference contribution


An experimental combustor, designated BKH, has been developed at DLR Lampoldshausen to investigate combustion instability. The combustor operates with cryogenic liquid oxygen and hydrogen propellants at supercritical pressure conditions analogous to real rocket engines. It features an excitation system for driving acoustic disturbances in order to study combustion instability phenomena. BKH experimental results are being used to develop and validate numerical models. Methods of simulating the influence of the excitation system on the BKH chamber have been examined and the results compared with BKH experiments under cold flow operating conditions.
