GENERATOR OF PRESSURE PULSES IN COMBUSTION CHAMBER ACOUSTIC CAVITIES AND LIQUID-PROPELLANT ENGINE GAS GENERATOR Russian patent published in 2014 - IPC F02K9/96 G01M15/02 G01M15/14 

FIELD: engines and pumps.

SUBSTANCE: generator comprises housing with connection pipe and prechamber to accommodate the sleeve made of dielectric to house electrodes. Note here that one electrode is arranged in prechamber axis to make the common electrode. Other electrodes are arranged in circle at equal spacing. Note here that axial electrode is connected with other electrodes by 0.02-0.5 mm diameter metal wires. Electrode other ends are intended for connected to high-voltage sources. Ends of electrodes arranged inside prechamber are bulged, purge nitrogen feed union being connected to said prechamber. With even number of electrodes arranged in circle, axial electrode end, in radial direction towards said electrodes, through radial intercrossing channels can be made to receive metal wires. Note here that ends of every said wire are connected with appropriate pair of opposed electrodes arranged in circle. Blank threaded hole is made at axial electrode end which crosses said through radial channels. Screw is fitted therein to clamp said metal wires to inner edges of axial electrode through channels.

EFFECT: generation of several stable pulses at single test of combustion chamber and gas generator.
