ВПЛИВ ТЕМПЕРАТУРИ НА ПРАЦЕЗДАТНІСТЬ ПАЛИВНОЇ СИСТЕМИ КОСМІЧНИХ ЛІТАЛЬНИХ АПАРАТІВ

Abstract

The tasks that modern spacecraft must solve during the flight task are constantly becoming more complicated. Accordingly, the conditions for the functioning of all systems and, above all, the fuel system are complicated. This system should provide the engines of the aircraft with fuel components when they start and operate under conditions of action of a variable field of mass forces, that is, in conditions of practical weightlessness. In these conditions, the nature of the impact on the performance of the fuel system of various external and internal factors changes significantly.
 The paper analyzes the degree of influence of the temperature of the structural elements of the spacecraft and liquid fuel on the performance of individual components of the fuel system. Some existing approaches to this issue are considered and it is concluded that it is necessary to conduct further research in this direction in order to improve existing and create new, more modern, fuel systems of multipurpose spacecraft and acceleration units.
