Abstract: This paper presents an analytical study of the unstable operation of a ramjet in ground testing. A culculation of the characteristics of the measuring system for the combustion chamber pressure is also presented to show the validation of the experimental data, A criterion of combustion stability are proposed on the basis of experiences.
