Abstract. The experimental research of the carbon composite material sample of payload fairing half structural element was carried out under different types of loading. Mathematical and physical modeling of the sample loading using aerodynamic flow was conducted. Heat loading was researched by the method of a thermal analysis during which typical heat dots corresponding to the changes in the sample structure were determined. Ultrasonic influence on the sample characteristics was considered. As a result, the value of heat leak to the structure surface while moving in the atmospheric phase of the descent was determined.

Abstract.The aim of the researchis the quality operations of the design process at the stage of research works on the development of active on-Board system of the launch vehicles spent stages descent with liquid propellant rocket engines by simulating the gasification process of undeveloped residues of fuel in the tanks. The design techniques of the gasification process of liquid rocket propellant components residues in the tank to the expense of finding and fixing errors in the algorithm calculation to increase the accuracy of calculation results is proposed. Experimental modelling of the model liquid evaporation in a limited reservoir of the experimental stand, allowing due to the false measurements rejection based on given criteria and detected faults to enhance the results reliability of the experimental studies; to reduce the experiments cost.. IntroductionIn this study, at the stage of scientific research as the main characteristics of the object, which is included in its quality, the reliability criterion of scientific resultsis applied.To assess the reliability of the research results is to establish the degree of closeness of numerical and experimental studies results. Taking into account such factors affecting the final result as: different conversion, assumptions and simplifications in the mathematical and physical models, using the wrong dimensions, human factors, external conditions the carrying out of the experiment, which lead to inaccuracy and various sorts of errors that require minimization.The methods of ensuring the theoretical results reliability were used at the stage of research works by using known solutions for the process under study and the licensed software, that confirmed with experiments and a satisfactory convergence of the calculated and experimental data.The analysis of the current level of theoretical and practical achievements in the field of quality operations in the early design stages of complex technical systems by Russian scientists: V. Vasil'ev, A. Akhtulov, A. Al'breht, D. Golovin, and foreign scientists: B. Anderson , V. Roshan Joseph , Harriet Black Nembhard, showed that there is a need for improved approaches, concepts and methodologies of quality operations theoretical and experimental studies, that is, the creation of the generalized characteristics of the research results, to evaluate their objectivity, depth, novelty and usefulness [1][2][3][4][5].
