DEVICE FOR MEASUREMENT OF CHANGE IN THRUST OF PLASMA JET ENGINE WITH CLOSED ELECTRODE DRIFT Russian patent published in 1998 - IPC

FIELD: engine plants of space vehicles. SUBSTANCE: device includes main circular ionization and acceleration channel, at least one hollow cathode located on the outside relative to main channel after its output portion, one anode, devices for supply of gas to be ionized connected respectively with hollow cathode and anode and devices for creating magnetic field. Proposed device contains magnetic flux sensors 101-104 located around accelerating channel, amplifiers 111-114 to whose outputs signals transmitted by magnetic flux sensors 102-104 are delivered and adding circuit 115 whose inputs are connected with amplifier outputs. EFFECT: enhanced efficiency. 10 cl, 9 dwg
