Abstract

Nowadays, hard competition between aerospace manufacturers calls for the development of innovative systems, implying long and costly studies. In rocket propulsion using liquid propellants, the com- bustion chamber is one of the key elements. If not designed properly, safety issues can occur, when high-frequency instabilities develop in the combustion chamber and provoke structural damage to the whole system. This phenomenon is particularly difficult to study experimentally, due to the high cost of the tests. Moreover, the power required for hot fire tests of rocket elements is so large that sometimes no experimental test rig can supply it.
