GAS TURBINE TURBOSHAFT AUTOMOTIVE RADIAL ENGINE WITH CENTRIFUGAL GASES OUTFLOW AND ITS OPERATION METHOD Russian patent published in 2018 - IPC F02C5/00 F01C1/04 F01D1/06 

FIELD: motors and pumps.

SUBSTANCE: invention relates to automobile engines building, allowing to use the combustion products with working medium temperature of about 2,000° as the working medium. Gas turbine turboshaft engine comprises compressor, by the branch pipe connected to combustion chamber, into which the fuel supply branch pipe from fuel pump is brought-in. Compressor is made dual, where each compressor rotor is fixed to the first stage corresponding turbine shaft, at that, the first stage dual turbine both rotors are side by side arranged at the same level in the turbine casing and comprise cages with the radially installed hollow blades. In the cages a perforation is made, which communicates the blades and cages internal volume, inside the rotors and coaxial to them perforated shafts are installed, made with possibility of rotation, on which forming the auxiliary compressor spiral blades are installed. In the first stage dual turbine casing, at the each rotor inlet branch pipes are installed for the hot gases removal into the free second stage turbine and branch pipes for the atmospheric air suction. In the first stage turbine casing, a common input branch pipe is installed, for the hot gases from combustion chamber introduction, and branch pipes for the air discharging into the combustion chamber; second stage free turbine rotor has a hollow shaft and perforation in the cage, as well as hollow blades; engine comprises the auxiliary air cylinder connected to the combustion chamber by the branch pipe.

EFFECT: technical result of invention is the blades cyclic operation, which allows to raise the gases temperature at the turbine inlet to 2,000°, this allows to reduce the gases on the rotor blades thermal effect intensity, that increases their service life, and also increases the engine efficiency; in addition, technical result is possibility to abandon the use of gearbox, possibility to use turbine for the motor braking, and obtain the additional fuel economy.
