Some shortening of the anode does'not affect appreciably the
forces acting on the flow of plasma in

Face-type dc plasma motor
Figure ý.6 shows a diagram of a plasma motor with a face-type
layout of the anode-cathode system and a lquia working medium.
The main advantage of this design is thb rational form of the'cathode
which presents the contact of structural materials, with the central
part of tiue plasma bunch having the maximum temperatures.
This motor consists of the folloiing main unitb:
an acceleratorgenerator,
working medium feed, cooling systemi, and poier supply.'
The accelerator-generator 'anit consists of a ring-shaped
molybdenum cathode 1 which can be cooled'by the organosilicon liquid,
heat-resistant insulatcr 2, and tungsten anode 3.
The working meditim supply unit conri'ts of tank 14 withI compressed
gas, tank 5 with the working medium and the heater, doding device
6, and injector 7.
