Abstract
In the study of combustion processes in the combustion chambers of air-jet engines, the main attention is paid to determining their thrust characteristics. The main way to determine the thrust characteristics is the direct measurement of the thrust generated by the combustion chamber or a charge of solid fuel. Another way to determine the thrust characteristics is to define the momentum of the jet flowing through the sonic nozzle according to the known flow parameters at the nozzle exit (pressure, temperature, and gas composition). Depending on the task at hand, it is convenient to use one of the indicated methods. In this paper, the results of determining the thrust characteristics of a model combustion chamber have been compared in two ways under the conditions of one experiment.
