Kurzfassung
Currently several green propellants as substitute for the highly toxic hydrazine are under investigation. A possible alternative are so called nitrous oxide fuel blends. This paper presents the results of combustion tests conducted with a premixed monopropellant consisting of N2O and C2H4. In four test series the influence of the mixture ratio, the chamber pressure, the chamber length and the mass flux on the combustion efficiency and on the heat flux is analyzed and discussed. Furthermore four empirical Nusselt correlations derived by Bartz, Cinjarew, Dittus-Boelter and Gnielinski are compared to the experimental results and finally modified to improve their accuracy.
