- W4285344560 abstract "Modern multi-purpose spacecraft for several years must perform complex and diverse tasks in outer space. At the same time, it is necessary to turn on jet engines dozens of times in conditions of practical weightlessness. At the time of starting the engine, the liquid fuel is mixed randomly with the boost gas. In this case, it is impossible to guarantee the contact of the drainage hole with the gas phase, and the drain hole with the fuel. To solve this problem, it is proposed to use various, so-called means of ensuring the continuity of fuel (MECF). The effectiveness of monitoring the position of the liquid in the flight conditions of the aircraft in the passive section of the trajectory is determined by the ability of the MECF to ensure the discharge of fuel from the tank without gas inclusions at any required time with a given flow rate and in the required amount with a minimum volume of unselected residues.
 The article deals with the features of the functioning of the SOST of the inertial type, which includes mesh phase separators (MPS). The need to use the MPS is due to the possibility of the gas phase entering the drain line, both in the passive section of the trajectory and at the stage of switching on the main engines, which can lead to a disruption of their launch. When fuel moves into the drain line, bubbles remain on the mesh surface and prevent the passage of liquid. 
 The article builds a mathematical model of the behavior of gas bubbles on the surface of the MPS in the flow of a viscous liquid. On the basis of the constructed mathematical model, the corresponding numerical calculations were carried out. The proposed method of engineering calculation makes it possible to determine such a MECF design that excludes the possibility of contamination of the surface of the MPS by gas bubbles and the disruption as a result of this normal functioning of the fuel supply system to the engines of spacecraft." @default.
