The invention relates to the field of power engineering and can be used, in particular, as the engine of the aircraft (La).

It is known device called a Stirling engine that converts thermal energy into mechanical energy of rotation of the shaft [RF patent №2056606, 1993].

The disadvantages of this invention include the complexity of the device due to the use of four-bar crank mechanism (CRG).

As a prototype, the device according to the patent of Russian Federation №2472005, 2011, entitled "external combustion Engine".

The disadvantages of the prototype device should include large overall dimensions, due to inefficient system of heat removal from the condenser.

The aim of the present invention is to reduce the weight and size of engine performance for L. A.

The essence of the invention is as follows.

In the known technical solution for removing heat from the condenser are hollow rods, rigidly secured to the motor housing. The rods are rigidly mounted on the cone-plate capacitors, both inside and outside of the hermetic enclosure. Cone plates made with the developed heat exchange surface, such as undulating. From the top of the truncated cone of the housing on the motor shaft �harddisk-images set screw propulsion

A disadvantage of the known technical solution is inefficient heat removal from the condenser with the help of wavy plates.

According to the invention, the stems are installed radially mounted internal and external radiators and how they connect with rods that can significantly improve the efficiency of the process of heat removal from the condenser and thereby reduce the size and weight of the engine.

The device of the external combustion engine.

An external combustion engine comprises a sealed housing 1 in the form of a truncated cone, partially filled with coolant, the case contains the evaporator 2 and the condenser 3, the housing contains insulating ring 4, which is the item of the housing and rigidly fastened as with evaporative section 5 and the condensing section 6 of the motor housing, the insulating ring are rigidly mounted on the impeller 7 of the turbine 8 with the rotor blades 9, covered by the rim 10, the impellers of the turbine is rigidly attached to the shaft 11 of the engine, mounted on the shaft of the turbine wheel with guide blades 12 covered by the rim 13, which is the annular magnet, the rims all wheel installed with the formation of the annular gap 14 with the body, wheels with guide vanes mounted for rotation relative to in�Lou on bearings 15, over the inner ring magnet installed external ring magnet 16, rigidly connected to the casing 17, the motor shaft is rigidly fastened to the screw 18, the capacitor contains hollow rods 19, around the evaporator is located a spiral combustion chamber 20 containing the nozzle 21, the rods are mounted radiators 22 with outer 23, 24 internal side of the housing constituting radially mounted trapezoidal plates with bushings 25, covering the terminals with a gap 26 is filled with a thermally conductive paste.

When the engine is running on solar power sealed enclosure protected by a screen 27 with corresponding openings for access of solar energy to the evaporator, a shaft connected to the generator.

The work of the external combustion engine.

When the supply of fuel to the nozzle 21 of the combustion products heat the evaporator 2, thereby converting the coolant from liquid to gas, in the form of steam. Vapor from the evaporative section 5 passes through the turbine 8 and enters the condensing section 6 of the engine, doing work on the rotation shaft 11, and is rigidly bonded with him working wheels 7 with the rotor blades 9, the hollow rods 19 with radiators 22 and the screw 18. The exhaust steam passing through the axial channels formed radially mounted 23 internal portions of the radiator, gives the excess teperature established internal portions of the hollow rods, covered by the bushing 25 with an annular gap 26 is filled with a thermally conductive paste. When this heat on the member is removed from the capacitor to the outside and subsequently moved the airstream created by the screw. The exhaust steam condenses on the walls of the radiator and the liquid phase is supplied to the inner surface of the condenser 3. Under the action of centrifugal forces the coolant in the form of a thin film through the gap 14 of the rim 10 and 13 of the turbine re-enters the evaporator. The cycle repeats.

The proposed technical solution in contrast to the known has the following advantages.

1. In the known technical solution of the heat sink plates and the rods are arranged among themselves in different planes (right angle), resulting in a point contact. In the proposed solution, both parts are located in one plane and in contact along the line, which provides a reliable and efficient heat transfer with each other.

2. In the known technical solution, the plates arranged one above the other, along the path of movement of the carrier in the radial direction, screen each other and impede the free radial movement of the coolant. The proposed technical solution for the movement of the heat carrier in radial direction created the most favorable conditions.

3. The presence of the annular gap between happy�atoron and hollow stem, filled with heat-conducting paste, significantly increases the heat transfer efficiency between the cylindrical parts. (4).

4. Hollow rod unlike equal-sized solid square has not only increased surface heat transfer, but also increased strength and rigidity.
