Developing a Test Stand to Verify Accuracy of Conducted Research at the Early Design Stages of Active Descent Systems of Spent Launcher Stages


Background/Objectives: This article deals with the make-up of a test bench and justifies selected parameters of an experimental model unit, heat carrier and model liquid. Methods: The authors employed mathematical and physical simulation. It should be stated that the necessity of solving a number of specific problems arises during physical simulation. Findings: A physical model of model liquid gasification has been described. A methodological approach has been suggested to assure accuracy of physical simulation as exemplified by investigation the model liquid gasification process based on a set of criteria that ensure accuracy and objectiveness of the physical model. The efficiency of suggested measures for enhancing experimental research accuracy has been provided. Due to the application of the suggested methodological approach on the developed test bench, the following results are achieved: experimental research data accuracy is enhanced; measurement reliability is enhanced; and fewer resources are spent for the experiments. Application/Improvements: Basic criteria of physical simulation in the field of heat and mass transfer that were developed are universal, simple and easy to be applied to research of a great variety of sophisticated technical systems.
