of the anode-cathode system from overheating by spreading the
discharge contact spot on the surface. The problems of cooling,
repeated switching of the motor, and frequent use are simpler to
solve. The disadvantage is the comparatively heavy weight of the
* ,capacitors.
These motors are generally used for correction.
motors can be used for individual cosmonaut use.
High-thrust
In dc motors the generation and acceleration of the plasma is
accomplished by direct current. The motors can be electromagnetic
or electrothermal. They can be both sustainer motors for interorbital
flights and correction motors. A 3haracteristic of these
motors is the high-temperature operating mnode of the anode-cathode
system.
Ac motors are electromagnetic motors in which the generaticn
and acceleration of plasma is accomplished by alternating current.
They include motors with a progressive magnetic field, high-frequency,
superhigh-frequency, and electrothermal motors. They can be designed
for various purposes.
The high temperatures of the plasma require particular attention
be given to the coolant system and the selection of the materials,
which in turn requires the solution of a large number of' co'apl.x
structural and technological problems.
The type of working medium (solid, liquid, or gas) determines
the structural shape of the power supply system and the plasma
generator.
Based on the arrangement of the cathode-ancde system, these
motors are divided into coaxial, face and track.
