Driven rotors unloaded in the housing by means of bearings with gas lubrication; in the hollows of the teeth of the driven rotor is bypass window 13, which are near Century MT injection channels 14 and filling the channels 15 communicated with the combustion chambers 16 in which is installed the fuel injector 17. The axial length of the rotor 11 is two times the length of the rotors 10, 12 and they are displaced diametrically oppositely from the axis of the male rotor. In the end covers 18 and the disks 19 of the housing in the area N. M.T., corresponding to the maximum volume of the chambers made the inlet 20 and outlet 21 of the inlet ports 22 connected respectively with the inner cavity of the gondola, which is communicated with the output of the low-pressure compressor 23 and the exhaust manifold 24, the output of which is connected with the working path of the gas turbine 25. Working camera with motors and seals with gas lubrication 26, 27, the design of which is known (SU, ed. mon. 958755 A, class F 16 J 15/44, publ. 15.09.1982). In addition, the motors are equipped with an active management system clearances between the rotors and the housing, which is similar to (SU, ed. mon. One obliteration gaps directly when the engine is running (EN, patent 2013582, CL F 02 In 53/00, publ. 30.05.1994). Inside the leading rotor is cavities, channels and heat exchange fins of the cooling system, and an axial hole in which, by means of spline connection (for example, with intermediate balls) with the possibility of axial displacement of the installed shaft 28 of the fan or screw 29 and the shaft 30 of the fan 31. The shaft 28 through the angular contact bearing 32 mounted in the frame 33, bonded through a fixed guide vanes 34 with the body. With the frame are fastened together also a guiding apparatus 35. On the shaft 28 fixed turbine 25, the fan 29 is connected turbine 36, with the fan 31 is fastened the last stage of the turbine 37, the nozzle 38 and the rear fairing (COCs) 39. The shaft 30 is passed through the axial hole of the rotor 9 and discharged through the radial-thrust bearing 40 located between the engines in case. In the axial hole of the shaft 30 posted shaft connection 41 between the turbine 42 and the rotor 23 of the low-pressure compressor. Crowns 43 directing vanes of the low-pressure compressor is installed or in the housing or drum 44, through which the blades 45 and the disk 46 is rigidly connected to the leading rotor 8. The compressor rotor is mounted on bearings 47, 48. The disks ventilyatsionnie blade of gas turbine engines instead of the rotor, while the shafts of the propellers, it is advisable to connect the shafts of the motors through reduction gear. It is also possible the performance of the installation with a front location of the fans, in this embodiment, the compressor and the inlet 51 may be installed on the front fan. When the rotation of the rotors 8, volume 11 magzumovich cameras varies from a minimum in a Century MT to a maximum of N.M.T. Approximately 30oto N. M.T. open outlet port 21, then the inlet box 20 and compressed in the compressor 23 air flow blowing out of the working chambers of a rotary engine, the combustion products through a manifold 24 are received in the gas turbine 25, 36, 49, 50, 42, 37. In the phase of ~270oafter a Century MT blowing pumped, the air is compressed to a pressure of ~ 2 MPa, through the window 13 and the discharge channel 14 with a twist is displaced into the combustion chamber 16 is mixed with fuel supplied by the injector 17, the mixture is ignited and burns with a high pressure of up to about 7 MPa, then the expansion of the combustion products and blowdown. Diametrically opposite the offset of the slave rotor 11 relative to the rotors 10, 12 provides trim radical forces of gas pressure on the driving shaft 8 and unloading their bearings. Power is recorded; torque on the fan increases additionally turbines 25, 36, 49, 50, 37. The free energy of the turbine 42 through the shaft 41 of the drive unit 23. Technical and economic efficiency of the proposal, it is useful to illustrate this with the following example:Main technical data of the propulsion system with 5-section rotary engines (approximate): Length, mm - 3800 The area of the midsection ( 740 mm), m2- 0,43 Weight, kg - 1100 Fan diameter, mm - 2400 The pass ratio - 56 Power - 8000 KW Specific mass, kg/KW was 0.138 The temperature in the combustion chamber - 2800 TO The degree of pressure increase (at an altitude of 10 km) - 200 UD.fuel consumption: 0.15 kg/kWh UD.pull - 0,134 kg/kgf The rotational speed of a shaft - 3000 rpm The air excess factor - 1 High technical indicators have a natural explanation: the high temperature of the gases in the combustion chamber in excess of about 1000 To level temperatures in modern gas turbines, a high degree of pressure increase, the possibility of exclusion from the design of the reduction gearing, etc. Careful optimization of the design and use of modern materials (ug is the R advantages. Installation retains the advantages of using a traditional gas turbine engines due coaxially their location (decrease midsection) and high efficiency axial fans or propellers. Rotary motor includes a stator 51 stop it working cavity formed by the Central cylindrical bore leading rotor 52 and four intersecting with the Central hole bores for the slave rotor 53; to which is bonded end caps 54, 55, in which the bearings 56, 57 are installed leading to the rotor shaft 58 and driven rotors 53, evenly spaced around the male rotor in the bores of the housing. Leading the rotor is provided with a ledge-teeth 59 cycloidal profile associated with depressions 60 on the driven rotors. In the Central cylindrical hole has outlet ports 61 pipes 62, the bores for the driven rotor is the inlet window 63 for purging the compression chambers 64, which are formed by the volumes of the cavities 60 and fragments of 65 in the Central cavity located between the Windows 61 and driven rotors. In addition, the bores of the stator under the slave rotor holds the outlet 66 and the inlet 67 of the window and rinsing troughs from combustion products. Inlet box 6 is placed in a single window with a common pipe; perhaps their separate execution and the connection of each with his pipe, for example, to purge cameras compress air to a higher pressure than when the blowing cavities from combustion products through the pipe 69 connected to the exhaust tract. It is advisable to execution of the branch pipes with the resonant length, which increases the efficiency of purging basins and recharge cameras compression by dynamic boost. The rotors are synchronized by gears communications 70, 71 installed in the housing of the ignition device 72, which may be a spark plug or fuel injector. Housing and rotors are made of heat-resistant materials with a low coefficient of thermal expansion (CTE), for example, structural ceramic, glass-ceramic, sapphire, plekon and other and connected with each other with minimum clearances of the order of 0.02-0.1 mm working surface can have a relatively "soft" abrasion coating, for example, on the basis of graphite; the tops of the teeth of the male rotor and the edges of the depressions of the driven rotors are covered with material of high hardness and wear resistance. In addition, by sealing the edges of the depressions on the tops of the teeth on the rear (downstream) surface of the teeth of the male rotor and polozhennyh along. The optimum number of teeth of the male rotor and the number of driven rotors is taken from two to five, and the number of teeth and the driven rotors can be equal, as in Fig. 4; (bearings 56 of the male rotor is almost completely discharged from the forces of gas pressure), or the number of teeth and the driven rotors are executed by the difference in the unit (for example, four of the slave rotor and five teeth; the positive effect of the uniformity of the torque on the output shaft 58). In the bores of the stator under driven rotors can be filled with additional channels 73 to increase the degree of expansion of the gas from the depressions 60, but this positive effect should be compared with negative short-term (almost instantaneous) leakage at the time of passage of the tooth tip of the rotor through the channel. Very simple design is shown in Fig. 6, 7, it contains a bidentate leading rotor 84 and two slave rotor 75 with three depressions 76 each, the inlet 77 and the discharge nozzles 78 to purge cavities with compressed air or bessovestnoi mixture, exhaust pipes 79, located in the front along the male rotor side of the camera housing extension 80, the vehicle ignition 81 (injector or spark plug). When COI is I through holes. Possible option of nozzles 82 and Windows 83 for purging the compression chambers 76, made separately from the nozzles 77 (see Fig. 7). When the engine through pipes 68, 69 compressed air from a blower or turbocharger is blowing depressions 60 of driven rotors, then the fuel injection through the nozzle 72 by a large margin, the corresponding speed of the engine, blowing the compression chamber through the window 63 with the release of combustion products through the nozzle 62, the compression to a minimum volume (C. M. I., see Fig. 4) where the end of the period of preparation of the mixture and ignition delay, then the ignition, combustion, expansion in the depressions 60, about twice the continued expansion in the chambers 74 and exhaust through the pipe 69 into the exhaust manifold and the turbine unit charge. The performance of the engine with the two tabs of the male rotor and the two driven rotors with three cavities each connection in the process of expanding the volume of the basin with camera extension before the release of gases into the exhaust pipe 79 (see Fig. 6), thus the need for the bypass channel available in the well-known analogue eliminated eliminated accompanying disadvantages. The same positive amatore, paired with four slave rotors with two cavities each. Non-contact seals provide a high circumferential speed of the rotor (of the order of 50-100 m/s), the adiabatic mode with the lowest dosed cooling the most heated seats corps and uncooled rotor; eliminates lubrication of rotors and waste oil, while losses from gas leaks less mechanical friction losses in reciprocating engines. The combined effect of these factors enables the creation of extremely light engine with a specific gravity of ~0.03 kg/kW, simple, reliable, environmentally friendly, long service life and high efficiency. 1.
