There are results of the magnet system
numerical computation of the Anode Layer
Thruster with power up to 100 watts, taking into account heat generation while
its work. The description of the numerical model for
computation of thermal condition of the thruster is given
and the results of the computation are
shown. On the basis of the
obtained profiles of temperature
distribution depending on the
amount of heat the computation
of the magnetic system is made. The range of powers at which there is no significant
demagnetization of the magnetic elements of the system and
disturbance of the magnetic field profile in the channel of the thruster. Numerical computations
were carried out in the software package
ANSYS.
Key words: thruster with anode
layer, thermal state, the
magnetic system, demagnetization.
