PLASMA-JET
ENGINE WITH CLOSED-CIRCUIT ELECTRON DRIFT
 FIELD:
space engineering; stationary plasma jet engines and anode-layer engines of
electric rocket engine units.
SUBSTANCE: engine has at least one compensating
cathode with outlet aperture positioned towards accelerated plasma flow and
anode unit incorporating annular discharge chamber with ionization and
acceleration zones formed by internal and external annular walls, and magnetic
system with internal and external magnetic poles; output aperture of
compensating cathode is disposed in zone confined on one end with external
magnetic pole plane and on other end, with conical surface crossing the line
intersecting interface ionization-to- acceleration zone and external annular
wall; angle of maximum 30 deg. is formed here between this conical surface and
external magnetic pole surface. External pole has annular projection on side of
accelerated plasma flow whose end surface is made in the form of cone.
EFFECT: enhanced reliability and service life of
engine. 2 cl, 2 dwg
