SOFTWARE AND METHODOLOGICAL COMPLEX FOR STUDYING QUASI STATIONARY OPERATING MODES OF PROPULSION PLANT
The article deals with the issues of numerical simulation of the distribution of parameters along the length of the combustion chamber of a propulsion system and nozzle in a quasistationary formulation. In the courses of special disciplines at the university, students get acquainted with various models of internal ballistics in propulsion systems: thermodynamic, gasdynamic and thermogasdynamic. When studying the influence of the gas flow velocity along the burning surface on the pressure level in the combustion chamber, in order to obtain an idea of the physical picture of the erosive combustion process and to get acquainted with the main laws of the occurring phenomena, numerical modeling is carried out. This paper proposes a developed software and methodological complex for the study of work processes in a quasi-stationary formulation. When creating the program interface, the possibility of independent work by students was taken into account, therefore, such functions as saving the initial data and calculation results to a text file are provided. In addition, the program contains a user error protection function. Testing of the software and methodological complex was carried out using the results of full-scale experiments, which allows us to conclude that the characteristics obtained are accurate. The presented developed software and methodological complex for the study of quasi-stationary modes of operation is used by students not only in the process of laboratory classes and term papers, but also in research activities.
