ROTARY BIROTATE GAS TURBINE ENGINE Russian patent published in 2019 - IPC F02C3/16 

FIELD: machine building.

SUBSTANCE: rotary birotate gas turbine engine comprises housing with pipelines for supply of oxidizing and combustible working bodies into impeller of first rotor. Impeller of the first rotor is made in the form of monoblock containing two-flow closed centrifugal wheel, enclosed by torus-shaped collector housing, made with separate combustion chambers, in which supersonic nozzles are installed tangentially. First rotor shaft has one end with an internal axial channel for supply of combustible working medium, and the other end is connected to a payload. Impeller of the second rotor is installed coaxially around the impeller of the first rotor, with possibility of independent rotation in the opposite direction, and is made of two identical disks connected to each other along the periphery by means of a rigid and hermetic ring of grooved shape. On outer sides of discs airflow channels are arranged tangentially along circumference. By their outer side disks are rigidly and tightly connected, each with its shaft made in the form of hollow cylinder open on both sides, made on internal surface with groove in the form of annular recesses, in which rigidly magnets are installed. In impeller of the second rotor there installed are tangentially and equally directed supersonic nozzles with elongated panel of subsonic part. Each of shafts of impeller of the second rotor is installed movably on the corresponding body of the pipeline of oxidizing working body, made in the form of hollow, open on both sides of cylinder with flanges and with groove on external surface of cylindrical part, in which current-conducting stator winding is installed.

EFFECT: higher absolute and specific power of the rotary birotate gas turbine engine, as well as efficiency of its operation in the specified dimensional constraints along the diameter of the circumscribed circle of rotors, as well as simplification of its design.
