Abstract

This thesis is about the ’Qualification of a Hybrid Rocket Engine for a Sounding Rocket’. With a particular focus on combustion instabilities and combustion efficency. First the backround and motivation of this thesis is presented. Following an introduction of the program Matlab and the within written code for the test analysis. Afterwards the theory of combustion instabilities is discussed with an main emphasis on hybrid rocket engines. In particular the theory and state of the art of lungitudinal waves, vortex shedding, low-frequencies and Helmholtz-instabilities are presented. Additional, possebilities for damping oscillations in terms of geometric changes, build ins and additives are discussed. After that, some chosen tests are presented and their results discussed. Finaly the Thesis gets summerized and and outview for future research is given.
