The aim of the invention is to increase the efficiency of the known propulsion.

The aim is achieved in that in the Central part of the combustion chamber is installed ball evaporator, the combustion chamber is made with a spherical body, covered with insulation, the outside of which has a spherical Golovnin, which is located concentric with the combustion chamber containers for compressed air and liquefied gas, connected to the combustion chamber of the radial tubes, and outside of Golovnina installed with a gap filled with water and connected with a water nozzle, steel casing, the diameter of the intake hole straight pipe exceeds the diameter of its cylindrical part, and the diameter of the outlet pipe thruster bolanderi with pedals and racks, located in engagement with the installed between the gear kinematically connected with the gear contact ring device interrupts the ignition circuit; Golovnin consists of upper and lower parts with screw connection, with upper hinges (hinges) fixed handle; steel casing bolted to the base of Golovnina.

In Fig.1 shows the stern of the boat, top view; Fig.2 section a-a in Fig.1; Fig.3 section a-a in Fig.1 (enlarged) when the engine is operating on natural gas, and Fig.4 is the same, the upper part of the engine operating on diesel fuel and gasoline; Fig.5 section b-B in Fig.3; Fig.6 section b-b In Fig.2; Fig.7 section G-G in Fig.6.

Mover LDK has a combustion chamber 1 (Fig.3) spherical shape, placed in the centre of Golovnina 2, on the peripheral part of which are annular chambers 3 and 4, respectively, for natural gas and compressed air, and a Central chamber 5 for compressed air. The combustion chamber 1 is connected with the chambers 3, 4 and 5, tube 6, through which the combustion chamber 1 is supplied natural gas and compressed air. Natural gas in the chamber 3 flows through the pipe, blocked by a valve 7, and the compressed air the settlement of the piping set 6, coming from cameras with compressed air and natural gas, electrospace 9, and in the upper part of the chamber 1 is set to the nozzle 10, which is the tube 11 from the tank with water, blocked by a valve 12.

Golovnin 2 consists of two parts: top and bottom, which are connected by means of a large screw thread 13. For ease of screwing and unscrewing the upper part of Golovnina 2 provides a handle 14 on the hinges (hinges) 15. The lower part of Golovnina is rigidly connected to the base 16, which is fixed on the bottom of the boat 17.

The combustion chamber 1 has a vertical gasovod 18, gradually turning in a horizontal tapered pipe 19, which at its front is recessed in the bottom of the boat 17 to about 1/10-1/20 of its diameter, and at the end of the stern of the boat 17 1/2 its diameter and replaces the keel to the stern of the boat 17. The pipe 19 is coaxially inserted the nozzle 20 with the annular gap 21 between the cylindrical surface and the pipe 19. The front part of the nozzle 20 has a smooth increase of the diameter to the diameter of the tube 19.

The combustion chamber 1, gasovod 18, the pipe piece 19, which is located against the pipe 20 and the inner surface of the socket 20 are heat-insulating coating 22, indicated in Fig.3 Phillips W is 23, inside three streamlined supports 24 is installed from the same heat-resistant metal teploenergiey evaporator 25 spherical shape with a small fairing 26 above gazivoda 18.

Golovnin 2 has a steel casing 27, which bolts 28 secured to the base 16. To seal between the casing 27 and the base 16 are laid rubber gasket 29. The casing 27 has inner and outer thermal insulation coating 30 (internal thinner coating 30 in Fig.3 not shown).

From the valves 7 and 8 lines nozzles to the clutch 31 is installed between the casing 27 and the base 16, through which they are connected respectively to the hoses in giving natural gas and compressed air. Through the clutch 31 is a pipe with a valve 32, going to the water pump, and the wiring 33, coming from electronica 9 to the coil 34 of the ignition capacitor, borrowed from the vehicle's electrical system.

A compressor for supplying compressed air into the chamber 1 shown in the form of a pump 35, a similar pump for pumping car cameras. The pump has two cylinders with pistons 36 and 37 and rod 38, the upper part of which is made in the form of pedals 39, rigidly connected with the toothed rail 40. Between which is engaged also gear 43, rigidly connected with the contact ring, with contacts, isolated between them and connected by the shaft 44 of the gear 43 to the weight of the pump housing connected to the terminal "-" of the battery 45. Terminal "+" of the battery 45 is connected to the contact 46 of the circuit breaker ignition, that the rotation of the gear 43 closes and opens the contacts of the contact ring, associated with the gear 43.

In Fig. 4 shows the upper part of Golovnina 2B propulsion LDK, using as fuel the gasoline or diesel fuel. Unlike Golovnina 2 for operation on natural gas (Fig.3) Golovnin 2B has in its upper part, the nozzle 47 for injecting liquid fuel instead of natural gas, and dome camera 48 for compressed air. In addition, the changed position in the chamber 1 of the injectors 10, electronica 9 and tubes 6 compressed air from the chamber 48 into the chamber 1.

The work of the propulsion unit using natural gas produced in the following order. Steering the boat 17 sets the chair in accordance with its growth by moving the seat 49 by using the handle 50 and an appropriate mechanism and, alternately pressing the foot pedal 39, actuates the pump-compressor 35, p the gas (or liquefied gas) into the chamber 3 (with open valves 7 and 8) and connects the circuit 33 work electronica to the battery 45. His assistant, a rotating pedal device, actuates the pump and generator to supply water into the casing 27, recharge the battery 45 (if necessary) or for lighting (at night). Water flow into the casing 27 is in the open valve 51 and pipe 52. After the appearance of water in the valve 51 is closed and the further ingress of water into the casing 27 is produced when air is compressed under it, to a pressure of 4 kg/cm²that fixed spring valve 53, letting the excess water, preventing a pressure increase of more than 4 kg/cm².

Moving the pedals 39 with the rails 40 are driven gear 41 and 43, causing the pedal 39, going down under pressure from one leg steering, raises another pedal up (along with other relaxed leg) and mud and break contacts of the circuit, the coil 34 of the ignition trigger electrospace 9, burn the fuel mixture of compressed air and natural gas in the chamber 1.

Ignited fuel mixture reaches a temperature of 2000^aboutC and a pressure of more than 10 kg/cm²but already through thousandths of a second temperature and pressure of the combustion products of the fuel mixture is reduced to 500^{grovania teploenergetichnogo housing 23 and the evaporator 25. In addition, a significant portion of exhaust gases "shoot" through the gap 21 in the pipe 19, creating a pulse of force, equal to the product of the pressure of exhaust gases in the cross-sectional area of the ring this gap. The pressure of the exhaust gases to the water in the pipe 19 will create accelerated movement of water in the pipe 19, is directly proportional to the pulse pressure forces the exhaust gases to water and inversely proportional to the mass of water in the pipe 19 and the pipe 20. Pulse pressure forces the exhaust gases to water will increase due to the transformation of the boundary layer of water with the hot exhaust gases into steam, which will increase the volume of gas-vapor stream and its impact on boundary layer of water. A small part of the exhaust gases will have time to penetrate into the tube 6, the diameter and length are chosen so that these exhaust gases do not have time to get through tubes 6 to cameras 3-5. The pressure in the chamber 1 is already through hundredths of seconds will be reduced to less than 2 kg/cm²due to the inertia encountered gas-vapor stream from the camera 1 into the pipe 19, and the pressure in the chambers 3, 4 and 5 will increase up to values exceeding 2 kg/cm²due to the inertia of the gas stream entering the camera 3-5.}

In the above-mentioned two mutually produc stopped, and then expelled into the combustion chamber 1. In the chamber 1, the combustion pressure will rise to 1.5-2 kg/cm²due to the receipt of compressed air and natural gas. Thus due to the higher pressure of the compressed air in the chambers 4 and 5 than natural gas in the chamber 3, or (at equal pressure) due to the larger diameter tube 6 leading from the chambers 5 and 4 to the camera 1 than the pipe 6 leading from the camera 3 to camera 1 (the second variant is more preferable than the first), first, in the camera 1 starts flowing air, which will displace the exhaust gases in gasovod 18 and further into the gap 21, and then you will start to receive natural gas from the chamber 3 into the chamber 1. When the fuel mixture of compressed air and natural gas in the ratio of 1:15 fills most of the camera 1 will include electrospace and ignition of the fuel mixture in the combustion chamber 1 and even gazivode 18, if she managed to get in gasovod.

After a few cycles of the ignition of the fuel mixture teplonasosnye devices 23 and 25 of the camera 1 has warmed up to the design temperature and the starting mode (transition mode) operation of the combustion chamber 1 will be replaced on the working operating mode, as this is the estimated time the water pressure in the casing 27 will rise to 4 kg/cm^2aboutC. the Main thermal losses are hot water from the gas-vapor stream entering through the gap 21, and can be determined by measuring the difference between the temperature of the water entering the pipe 20 and out of the pipe 19. Apparently, these losses will not be more than 30% therefore, the efficiency of the engine (without taking into account the efficiency of propulsion) will be more than 70% retention rate of movement of the boat is made with the arm 56 of the lever type, turning two wheels 57, connected by a parallelogram mechanism. Wheels 57 are located on both sides of the pipe 19 at a distance from it, sufficient for their normal operation.

Stop the engine LDK is stopping pedaling 39, turn off the natural gas supply and disconnect the circuit from the battery 45.

Propulsion has higher efficiency, lower noise and easier to manufacture compared with known boat propellers.
