Abstract

This article is devoted to the problem decision of mathematical models building as to the dynamics of liquid propellant components in tanks. It shows that it is necessary to apply special dynamic models of liquid component behavior for different phases of SC injection into the orbit. Special attention is paid to cryogenic propellant modeling.

Keywords:

propellant dynamics, over-loads, Launch Vehicle (LV), Spacecraft (SC), Upper Stage (US).
