AbstractAn engineering technique is suggested to calculate a combustion chamber thrust values for pulse-jet detonating engines. This technique allows us to reduce significantly computation costs and time needed to solve the problem. The one-dimensional classical theory is used to compute a propagation of detonation wave in the chamber. A finite-element model based on the Euler equations is used also to compute non-steady flow of combustion products as well as to calculate filling of the chamber with a fuel mixture. A demonstration example is presented for the technique.
