UNIT OF TURBO-MACHINE AND TURBO-MACHINE WITH SUCH UNIT Russian patent published in 2011 - IPC F23R3/58 

FIELD: machine building.

SUBSTANCE: unit of turbo-machine consists of circular compressor compartment, of turbo-machine case, of circular compartment of fuel combustion, and of circular turbine compartment, rotor of which is rotated with gases escaping compartment of fuel combustion. Also, air jet escaping the compressor compartment facilitates rotary motion with angle of incline relative to lengthwise axis of the turbo-machine. The case of the turbo-machine includes a circular external jacket centred relative to lengthwise axis of the turbo-machine and a circular internal jacket coaxially secured inside the external jacket by means of several radial fastening poles. The fuel combustion compartment is equipped with devices for angular distribution of air imparting rotary motion to jet of gases escaping the fuel combustion compartment; also, gas jet has incline angle in essence equal or exceeding incline angle of air jet leaving the compressor compartment. Devices for distribution of air are made at level of the turbo-machine case and secured with poles. Each of fastening poles has incline angle relative to lengthwise axis of the turbo-machine in essence equal or exceeding incline angle of air jet leaving the compressor compartment and required for transfer of rotary motion of the first step of the turbine compartment. The unit of the turbo-machine consists of additional devices for angular distribution of air corresponding to one or several structure elements chosen from group including a fairing of fuel combustion compartment, devices for injection of fuel to fuel combustion compartment, a cross wall of the fuel combustion compartment arranged along axis of walls of the fuel combustion compartment.

EFFECT: reduced value of aero-dynamic force required for rotary motion of first turbine step, and also reduced weight and increased compactness of turbo-machine, reduced expenditures for fabrication.
