Thermodynamic method of calculation of rocket combustion chamber volume. Experimental results and conclusions

摘要

The represented work give a method of the calculation of the volume of rocket combustion chamber on the base of boundary characteristic chamber lenght, discovered through the exploration of the vaporization and explosion process of single drops of hydrocarbon fuel in gaseous oxygen stream. Selected control parameters were researched on the experimental stand of which the principal part was the heat microscope Leitz. Single drops of furnace oil, mazout, kerosene, benzine, methanol were examined in air, nitrogen and oxygen stream. On the base of experimental results of explosion was established a relation between the boundary temperature of oxygen stream and the explosive mass of the drop for the suppositional conditions in the chamber and to get the correct injection system.
