METHOD OF INCREASING A REACTIVE THRUST IN A TURBOREACTIVE TWO-CIRCUIT ENGINE AND A TURBOREACTIVE TWO-CONCURRENT ENGINE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC F02K3/06 F01D1/32 F02C3/16 

FIELD: motors and pumps.

SUBSTANCE: method of increasing the reactive thrust in a turbojet dual-path engine involves supplying the oxidizing and combustible working fluid to the primary path of the primary circuit, their mixture formation, combustion and subsequent outflow of combustion products therefrom, to obtain mechanical energy for rotating the motor fan. Oxidizing working medium is supplied to the flow path of the second circuit. Expiration of combustion products of oxidizing and combustible working fluid is carried out through the engine nozzle with the formation of a propulsive thrust pulse. Over-enriched mixture of oxidizing and combustible working fluid is supplied to the combustion chambers of the rotary gas turbine engine introduced into the flow path of the first circuit. Resulting products of incomplete combustion upon exhaustion are directed radially into the flow path of the second engine circuit to mix them with the flow of the oxidizing working fluid. Combustion of this mixture is carried out with the subsequent supersonic exhaust of the products of its complete combustion through the nozzle of the engine.

EFFECT: invention is aimed at increasing the power and economy of the turbojet two-loop engine, reducing its size and weight, increasing the resource and reliability of operation.
