Abstracts:

The paper deals with the results of experimental investigations of combustion of stoichiometric propane-oxygen mixture inside a ring-shaped bubble. It is injected on the metal-liquid boundary. The gas combustion dynamics inside stationary formed bubbles and further hydrodynamic stages of bubble extension and bubble pulsing after combustion of propane are studied. The measurements of force impulse applied to a metal wall are performed. The measurements correlate with photographs of hydrodynamic processes. It is shown in the work that direct pulse gas combustion in water provides force onto the traction wall. This will make it possible to design movers of a new type with direct conversion of chemical energy to kinetic energy of body and avoid energy-consuming complex and intermediate devices (compression ignition engine, reducer, propeller).
