FIELD: mechanical engineering; gas-turbine engines. ^ SUBSTANCE: proposed pulsating gas-turbine engine contains intake diffuser, fan, compressor connected with combustion chambers and then with nozzles of gas turbine or jet engine. Combustion chambers are installed parallel to shaft and their inlet holes open to inlet valves or fixed end face distributor. Outlet pipes from opposite side of combustion chamber are connected, in their turn, with inlet holes made from side of shaft of curvilinear channels of gas-generator turbine. Gas generator turbine is installed on shaft and it has radial tilted to radius, or diagonal relative to shaft curvilinear channels formed by blades curved over periphery of rotor to side opposite of its rotation. Ring guide assembly is made on periphery of gas-generator turbine to which guide assembly in form of one, two or more crescent-shaped space adjoins directly or adjoins rotor of gas generator turbine. Each said crescent-shaped space adjoins in narrowing parts shutoff devices for periodical closing of outlet hole of minimum one curvilinear channel at rotation of gas-generator turbine. Hole is made in each crescent-shaped space wall to adjust size of hole, said hole being connected with nozzle of additional gas turbine or with nozzle of jet engine. Additional shutoff device is made in widest part of each crescent-shaped space for instance, in ring guide assembly. Said additional shutoff device is installed with calibrated clearance on gas-generator turbine to overlap outlet hole of minimum one curvilinear channel at rotation of gas generator turbine. ^ EFFECT: increased efficiency. ^ 3 cl, 3 dwg |
