FIELD: engines and pumps.
SUBSTANCE: plasma engine with closed electron drift comprises primary circular ionisation channel confined by structural elements from insulating materials and exposed at its outlet. At least one hollow cathode is connected with ionising gas feed line. Ring anode concentric with primary channel is spaced from its exposed end. Circular buffer chamber is arranged at primary channel inlet part, behind anode zone, its radial size exceeding that of the primary circular channel. Pipes to feed ionising gas are communicated in direction towards anode via circular distributor with zone different from that of anode.
EFFECT: higher thrust, simplified design, guaranteed operating cycle.
