JET ENGINE Russian patent published in 2004 - IPC

FIELD: transport engineering.

SUBSTANCE: proposed jet engine contains device for converting energy and device for vaporing liquid fuel between which continuous-action working combustion chamber is installed. Liquid fuel vaporizer is made in form of igniter provided with nozzle with spark plugs in its inlet part, and device for preparation of fuel and fuel nozzles for delivery of gaseous fuel into working combustion chamber is installed in outlet elongated part. Combustion chamber is provided with inlet air device with diffuser, heat part with spark plugs and outlet contraction part made elongated in form of neck getting into energy converter. The latter is connected with entry of jet nozzle through mixing chamber and is made in form of several series connected cylindrical pipes fitted into each other with clearance. Cylindrical pipes of energy converter have different diameters of holes. Diameters of following pipes are greater than diameters of preceding pipes. Mixing chamber is connected with divergent part of jet nozzle at outlet of which chamber is installed directing gas-air flow parallel to engine axis. Vacuum chamber with air conduit pipes is installed at other side of engine housing at outlet of air intake. Hemisphere with holes, into which suction air conduit pipes get, tightly first vacuum chamber from opposite side. Suction air conduit pipes connect energy converter with vacuum chamber. Vacuum chamber is cylindrical, with outer and inner envelopes. Axial-flow air compressor is installed inside inner envelope before device vaporizing liquid fuel. Air turbine is installed on one axle with compressor at inlet of air intake.

EFFECT: increased service life and efficiency of engine.
