Description
Summary:Results of experimental investigations in a flow-type annular cylindrical combustor with an outer diameter of 503 mm are reported. The influence of air addition to products of continuous spin detonation of CH 4 / m H 2 –air mixtures on the parameters of detonation waves, the pressure in the combustor, and the specific impulse is considered. It is demonstrated that air injection into detonation products increases the velocity of continuous spin detonation, the pressure in the combustor, and the thrust, whereas the specific flow rate of the fuel decreases.
