Description

 The invention relates to power engineering and power engineering and can be applied in the gas industry, in transport and in other industries.

 The peculiarity of gas internal combustion turbines is that they use reactive forces to obtain torque on the shaft during the combustion of a combustible mixture in internal combustion chambers.

 Closest to the invention is a gas turbine of internal combustion, comprising a housing, a rotor with a shaft and a hollow hub, internal combustion chambers bounded by the internal surfaces of the gas nozzles with valves, and an ignition system (RU 2116480 C1, class F 02 C 5/04, publ. . 07.27.1998).

 However, said turbine has drawbacks.

 It is characterized by limited power, since the channels for supplying a combustible mixture are placed in the form of a collector in the body of a hollow shaft, which limits the live section of the channels, power and efficiency of the turbine. Spark contacts in the turbine are placed individually in each internal combustion chamber, which ensures the synchronization of their work, thereby also reducing the efficiency of the turbine.

 The objective of the present invention is to increase the efficiency of the turbine and simplify its design. The problem is solved due to the fact that the internal combustion chambers have a common channel in the hub with a pipe for supplying a combustible mixture, and a slotted collector is installed at the end of the channel. Moreover, the slotted collector consists of a fixed disk with through holes in the form of a Maltese cross and a movable disk with similar through holes.

One disk has one spark contact, and the other disk has four contacts established relative to each other with an angular interval of 90 ^o .

 The invention is illustrated by drawings, where in Fig.1 shows a combustion chamber; figure 2 - the hub; figure 3 - the end face of the hub with disks; figure 4 is a General view of the turbine, a longitudinal section; figure 3 is a section aa in figure 3.

 In the turbine, the rotor 1 consists of internal combustion chambers 2 mounted on a hollow hub 3. A pipe 4 for supplying a combustible mixture is installed at the end to the hub 3, a fixed disk 5 with through holes 6 in the form of a Maltese cross is fixed at the end of the pipe 4. At the end to the hub 3, a movable disk 7 is fixed with slotted holes 8 in the form of a Maltese cross. In the body of the disk 7, spark contacts 9 are installed opposite each hole 8. In the body of the stationary disk 5, one spark contact 10 is installed.

 The turbine has exhaust pipes 11 with control valves 12. The turbine shaft 13 is mounted on two bearings 14, 15.

 The turbine works as follows. Through the pipe 4, a combustible mixture in composition with air is supplied; during its rotation, the movable disk 7 / disk 7 is mounted rigidly in the end face of the hub 3 and rotates together with the rotor 1 / then closes, then opens the through holes 6 in the fixed disk 5.

 When opening through holes in the hollow hub 3, a combustible mixture rushes under pressure while filling the cavity of the hub 3 and all of the internal combustion chambers 2.

 With further rotation of the rotor 1, the through holes overlap with the movable disk 7, while the spark contacts between the movable disk 7 and the stationary disk 5 are aligned.

 When these contacts are combined, a spark arises, the combustible mixture located in all the internal combustion chambers 2 is instantly ignited, and there is a “clap” with exhaust gases emitted through the nozzle-couplets 11 when the valves 12 are synchronized. Synchronous appearance of “pops” in all the chambers 2 of the internal combustion is ensured by the fact that the chambers 2 are activated as a single unit for the reason that they are communicated by a common hollow hub 3. The same occupancy rate of the chambers 2 of the internal combustion with a combustible mixture and their instantaneous operation and cotton provides maximum turbine efficiency.

 Under the action of reactive forces on the shaft there is a torque that drives the rotor 1 of the turbine.

 Next, the cycle repeats.
