Problems related to dynamics of space structures featuring

liquid propellant leaking out of spherical vessels

Bauman Moscow State Technical University, Moscow, 105005, Russia

The article studies the influence of liquid propellant on dynamic characteristics of space-

craft. We present numerical solutions to the problems related to oscillations of liquid

propellant leaking out of static spherical tanks into a fuel feed. We considered oscilla-

tion problems for liquid propellant leaking out under low-gravity conditions. We supply

a solution to the boundary value problem for proper motions of a fuel tank rotating in

reference to an arbitrary point and featuring a spherical cavity partially filled with liq-

uid, leaking out through an intake device.

Keywords:

spacecraft

liquid propellant

small oscillations, perturbed motion, static tank,

moving tank, spherical vessel, intake devices.
