FIELD: engines and pumps.SUBSTANCE: proposed engine comprises main circular ionization and acceleration channel, at least one hollow cathode, circular anode, pipe with header to feed anode with ionised gas, and magnetic circuit to induce magnetic field in said main circular channel. Said main circular channel is composed around engine axis. Said node is arranged aligned with said main circular channel. Magnetic circuit comprises at least one axial magnetic core surrounded by first coil and inner rear polar tip that makes a solid of revolution, and several outer magnetic cores surrounded by outer coils. Said magnetic circuit incorporates extra, in fact radial outer first polar tip making the concave inner peripheral surface and, in fact, radial inner second polar tip making the convex outer peripheral surface. Said peripheral surface represent corrected profiles. The latter differ from circular cylindrical surface to make variable-width clearance there between. Maximum clearance is located at sections aligned with location of outer coils. Minimum clearance is set at sections located between said outer coils to produce uniform radial magnetic field.EFFECT: higher power output, decreased amount of wires and their weight.7 cl, 8 dwg |
