Abstract
The combustion in a free cylindrical gas charge caused by detonation transmission from the initiating tube was experimentally investigated. The dependences of the combustion velocity change along this charge for stoichiometric mixtures of ethane, ethylene and propane with oxygen were obtained. A pulsating combustion pattern along the charge was observed, as a consequence of the damped oscillatory process. The speed of this process varied from the detonation velocity at the section of the initiating tube to 200–350 m/s at the end of the gas charge.
