Abstract

The utility model relates to a gas turbine composed of a steam turbine type main gas turbine, an auxiliary gas turbine and a reversing four way connected between the main gas turbine and the auxiliary gas turbine. The auxiliary gas turbine is provided with two air inlets which can drive a rotary wheel of the auxiliary gas turbine to rotate forward and backward. The two air inlets are respectively connected with two air outlets of the reversing four way, the air inlets of which are connected with the exhaust outlet of the main gas turbine. High pressure draught extracted by the main gas turbine is guided and accessed in the auxiliary gas turbine by the reversing four way, the rotary wheel of which is driven to rotate forward (or backward) to directly change the direction of output power. The utility model is especially suitable for being used as the engine of a small car.

Description

Wheel type gas-turbine

The utility model relates to gas turbine, belong to engine art.

Existing various gas turbine generally by fuel nozzle ejection combustion gas, form high temperature and high pressure gas through the ignition device burning and act on impeller and make it high speed rotating, drive and be attached thereto the outside outputting power of the main axis rotation that connects.Such gas turbine, it is that design is constant that its impeller is subjected to the direction of pressurized gas effect, thereby the sense of rotation of the main shaft of its outside outputting power also is constant, need the back and forth occasion of driving at some, as as the motor of automobile the time, often need could satisfy its realization two kinds of operating modes of advancing, move backward by the driving mechanism of external complexity.

The purpose of this utility model provides a kind of internal combustion rotor engine that can directly change its power outbound course.

The internal combustion rotor engine of realizing the purpose of this utility model by main combustion machine, auxilliary combustion machine and be connected in main combustion machine and auxilliary combustion machine between the commutation four-way constitute, described main combustion machine and auxilliary combustion machine are steam turbine, the steam turbine of serving as auxilliary combustion machine has two suction ports, one of them suction port is the just commentaries on classics suction port that its runner is just being changeed, another suction port is the counter-rotating suction port that makes its runner counter-rotating, the suction port of commutation four-way and the relief opening of main combustion machine join, two air outlets join with the forward and backward suction port of auxilliary combustion machine respectively, and another air outlet communicates with atmosphere.During work pressure fuel from the ejection of main combustion machine nozzle, after spark ignitor, form the rotation and spray at a high speed rapidly of runner that the High Temperature High Pressure hot-fluid makes main combustion machine from relief opening, enter auxilliary combustion machine through the commutation four-way, the impeller that acts on auxilliary combustion machine makes it rotation, by the outside outputting power of affixed with it pto.The direction of institute's outputting power, both sense of rotation of pto can change by operation commutation four-way, and when the high pressure gas that will lead the combustion machine when the commutation four-way was connected to the just commentaries on classics suction port of auxilliary combustion machine, then this exhaust was just changeed auxilliary combustion machine runner; When the high pressure gas that will lead the combustion machine when the commutation four-way is connected to the counter-rotating suction port of auxilliary combustion machine, then make its runner counter-rotating, both exported one with previous reverse power.When not needing external outputting power, the commutation four-way then connects the exhaust of main combustion machine and is put in the atmosphere.Can fuel nozzle and ignition mechanism be set respectively at two suction ports of auxilliary combustion machine, in the hot-fluid that main combustion machine enters, sneak into high-pressure gas (oil) and igniting once again again, improve the outputting power of subsidiary engine.For guaranteeing the abundant burning of main combustion machine fuel, can be at rotary wheel shell outer periphery one shell of main combustion machine, between the rotary wheel shell outer wall of this outer casing inner wall and main combustion machine, compression impellor is set, and this compression impellor is fixed in outer stretching on the outer runner shaft of rotary wheel shell, utilize the rotation of runner shaft, the rotation of drive compression impellor is pressed into main combustion machine suction port to the outside fresh air inspiration, and the burning that can be main combustion machine fuel provides enough oxygen.

The utility model is simple in structure, manufactures easily, can be directly the size of operating mode by control commutation four-way and fuel feeding realize stepless change and change the direction of outputting power, be particularly suitable for doing the motor of compact car.

Provide embodiment below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of present embodiment

Fig. 2 is the schematic top plan view of Fig. 1

As shown in Figure 1, 2, the utility model is made of main combustion machine 1, auxiliary material machine 2 and commutation four-way 3, main combustion machine 1 and auxilliary combustion machine 2 are steam turbine, just change suction port 5 and the counter-rotating suction port 6 of auxilliary combustion machine 2 join with two air outlets 7,8 of commutation four-way respectively, the relief opening 9 of main combustion machine joins with the suction port 10 of commutation four-way, and another air outlet 11 of commutation four-way communicates with atmosphere by silencing apparatus 12.The master is fired the gas nozzle 14 ejection high-pressure gas (oil) of machine during work, make it fire rapid expansion through spark plug 15 igniting, forming high-temperature high-pressure air flow orders about its runner 16 high speed rotating, discharges from relief opening 9, import auxilliary combustion machine through the commutation four-way and drive auxilliary combustion machine runner 17 high speed rotating, drive affixed with it pto 18 outside outputting powers.Air-flow after the acting then connects a silencing apparatus 20 and enters atmosphere through auxiliary exhaust hole 19.

Can

fuel nozzle

21,22 and

spark plug

23,24 be set respectively at two suction ports of auxilliary combustion machine, in the defeated next hot-fluid of main combustion machine, sneak into high-pressure gas (oil) and igniting once again again, can improve the outputting power of subsidiary engine.

Rotary wheel shell 25 outer periphery one shell 26 at main combustion machine, it is affixed with the runner shaft 28 of main combustion machine to be symmetrical arranged compression impellor 27 betwixt, utilize the rotating band dynamic pressure gas impeller rotation of the runner shaft of main combustion machine, thereby extraneous fresh air inspiration, be pressed into main combustion machine suction port 29, for the fuel combustion of main combustion machine provides enough oxygen.
