Abstract: The results of calculations of the pressure, flow rate, and temperature in the combustion chamber of a pulse detonation engine (PDE) for the conditions realized in the experiment are presented. On the basis of the developed mathematical model, the multiparameter calculations are performed for physical processes occurring in the working path of a PDE. We studied the conditions for the occurrence of oscillations in the PDE combustion chamber. For certain values of the parameters of the set-up, the oscillations have constant amplitude and frequency. These results are in good agreement with the data of other authors. The conditions under which the detonation engine can operate in the pulse mode are also investigated in the paper.
