METHOD AND DEVICE FOR CONVERTING HEAT ENERGY INTO KINETIC ENERGY OF REVOLVING WORKING MEDIUM Russian patent published in 2003 - IPC

FIELD: power engineering; heat-to-kinetic-energy conversion. SUBSTANCE: engine rotor is assembled of three basic systems having common axis of revolution and rigidly coupled together. First one is three-chamber toroidal system. Second is helical system whose sense of rotation is varied to supply air to combustion chamber. Third is helical system whose sense of rotation is varied to evacuate working medium from discharge chamber. Toroidal system chambers are disposed in tandem in common plane of revolution and are intercommunicated through annular channels. The latter are located in same plane as chambers. Chamber which is first from axis of revolution functions to separate and accelerate charged particles. For the purpose it mounts magnetic field windings and polar electrodes building up magnetic field. When chamber functions to accelerate charged particles, it operates as plasma-jet engine. When operating for power-take-off, it functions as MHD generator. Second chamber that functions as combustion chamber mounts fuel injectors, ignition plugs, and helical air-supply system. Second system is assembled of two groups of spirals coiled in opposite sides of revolution gradually converging toward straight tube which enables varying direction of revolving air flow and matching it with sense of rotation of working medium in chamber. Air-entrapping nozzles are mounted at inlets of spirals. Third chamber which is most distant from axis of revolution mounts third system disposed above second one. Third system has two groups of spirals coiled in opposite sides of revolution gradually converging toward straight tube. Third-system straight tuber is disposed above that of second system in a spaced relation providing for working medium discharge. Such arrangement makes it possible to reverse rotation of discharged working medium flow. EFFECT: enhanced efficiency and improved starting conditions of engine. 2 cl, 10 dwg
