METHOD OF ENERGY CONVERSION IN POWER PLANT (VERSIONS), JET-ADAPTIVE ENGINE AND GAS GENERATOR Russian patent published in 2002 - IPC

FIELD: self-contained drive for high power mobile electric generators, propulsion units of vehicles and other devices and mechanisms. SUBSTANCE: according to proposed method, torque on power plant rotor shaft is obtained owing to reactive thrust created by reactive mass of combustion products produces in periodical combustion chamber and transformed into pulses of supersonic reactive jet getting out of jet device into additional masses connecting device where vacuum is built by reactive jet and supersonic jet of combustion products in this device and additional gas masses are delivered into device, then additional gas masses are accelerated by transmitting to them part of energy of combustion products reactive jet pulses and combined reactive mass is formed to create reactive thrust. According to other version, part of available kinetic energy left after creating a torque is utilized by means of blade turbine which is not kinematically coupled with power shaft. Reactive mass jet flow is converted into kinetic energy of rotation of devices kinematically coupled with this turbine and having inertia mass by means of which it is accumulated and, if necessary, converted into electric energy and potential energy of compressed gas. To convert energy in jet-adaptive engine reactive mass is obtained using several working media of different thermodynamic characteristics. Reactive jet is formed in jet device by means of main working medium featuring high potential energy, this jet is directed into additional masses connecting device and is used as active jet in process of connection. Other working medium of potential energy smaller than that of main working medium is directed to inlet of same connecting device. According to proposed method of energy conversion in gas generator, at partial expansion of combustion products in closed volume of periodical combustion chamber, spool valve is shifted from initial position, in which spring is released and exhaust channel is closed, through certain distance. In process of covering the distance, spring is compressed for accumulating energy provided its return into initial position, and passages for discharge of combustion products are opened. Under action of compressed spring, valve is stopped and return travel is started during which fuel is injected under pressure and compressed air is fed to form fuel-air mixture for following thermodynamic cycle. EFFECT: increased efficiency. 68 cl, 32 dwg
