METHOD OF CLEANING STATIONARY PLASMA ENGINE ACCELERATION CHANNEL WORK SECTION OF EROSION PRODUCTS Russian patent published in 2012 - IPC F03H1/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to electric jet engines and plants built around accelerators with closed electron draft called stationary plasma Hall engines. It may be used to increase efficiency and stability of operating performances. Cleaning is performed by increasing magnetic field induction radial component in acceleration channel to B=(1.2-1.,5) B_op, where B_op is optimum radial component at which discharge current reaches minimum. Note here that discharge current is maintained at rated level while discharge voltage is kept at rated level or increased to magnitude not disturbing engine efficiency.

EFFECT: stable characteristics in space operation and ground tests thanks to efficient removal of erosion products.
