The invention relates to space technology and, in particular, to energy and can be used in space technology for converting solar energy into electrical energy and transfer it to the surface of the Earth, moon, or other objects by laser radiation. Thus the second invention that is used in the first, may have broader application, namely in the interest of space technology for carrying with it high-precision angular and geometric and remote measurements, for information transfer, as well as signaling devices for the detection or tracking of space or down devices, and on Earth in geodesy and cartography as a brand.

Known spacecraft for remote transmission of energy, which includes solar energy installation, instrumentation and propulsion module with control systems, cooling system, and a system for remote transmission of energy in the form of laser radiation (application for a patent RU №94032672/11 from 08.09.1994, B64G 9/00, publication date: 10.07.1996 year). The disadvantages of this design are: performing device for transmitting energy in the form of a single powerful laser, resulting in a lack of reliability and durability of the station, as the breakdown or failure in the operation of lasers and devices, providing it, R is the bot leads to failure of the entire space stations

Also known space solar power station (CCAS), which includes a base module that contains the control system with a host computer, cooling system and power supply system, United with him fotopresentatie panel, and the remote transmission of energy, including the mirror system (presentation materials company "ASTRIUM", Prague, 01.10.2010 GI website of the said company - www. astrium.eads.net). The disadvantages of this design are: performing device for transmitting energy in the form of a single powerful laser, resulting in a lack of reliability and durability of the station, as the breakdown or failure in the operation of lasers and devices, ensuring its operation (multi-circuit cooling system), leads to failure of the entire space of the plant, in addition, fotoprogramma panel in the form of thin-film solar cells also has several disadvantages such as low efficiency, large energy losses in a cable network, its large size and weight, which also leads to reduced efficiency, reliability and durability of the station. Performing multi-circuit cooling system necessary to ensure the work of a powerful laser also reduces the reliability of SCES due to the complexity and weight of the design. This solution is the closest to the proposed space solar power station and selected as a prototype.

The technical solution of the present invention is directed to the achievement of the technical result consists in increasing the efficiency, reliability and durability of SCAS.

This technical result is achieved by the fact that, as known, is used as a prototype, space solar power station that includes a base module that contains the control system with a host computer, cooling system and power supply system, fotopresentatie panel connected to the base module, and the remote transmission of energy, including the mirror system, in the proposed space solar power each photoprobes panel is made in the form of panels of two types of photovoltaic panels and Autonomous fotoizluchayuschih panels (AFIP) interconnected with the possibility of self-realization, for example, in the form of actuators made of metal with memory and building in a closed flat zigzag shape. Photovoltaic panels are mounted at the beginning of the chain of panels and the first of them is connected with the base module. Each solar panel is a photovoltaic battery mounted in CT the ACE in the form of hexagonal prisms of carbon fiber. The upper end of the framework is a mesh-rod structure, in grid cells which are mounted Fresnel lens, placed in their tricks and electrically connected to the power supply system base module with solar cells mounted on the heat sink base frame, to which are connected the terminals of the upper end of the frame. Each Autonomous fotoizluchayuschih panel consists of a frame in the form of hexagonal prisms of carbon from the heat sink base and the top face, made in the form of a mesh-core design, in cells which are mounted Fresnel lens. The rods of the frame are connected with the heat sink panels, coaxial to the Fresnel lenses. While this heat sink is a mesh-rod structure of the carbon fiber mixed with silicon carbide in the amount of 20%-25%, the nodes of which are the solar cells, between which is laid a layer of insulation material, and the rods attached to the nodes on the opposite side of the grid, is connected with the heat sink base frame. In addition, within a frame, and mounted the control unit fotoizluchayuschih panel receiving and transmitting antenna, a device for converting electrical energy into light, in the form of fiber lasers with blocks on acci, the adder and energy storage. When the solar cells are electrically connected with the pumping units and the control unit through the energy storage. The remote energy transfer is also equipped with an adder laser radiation, and the adders each fotoizluchayuschih panel is connected to the adder system for remote transmission of energy through a fiber optic cable. The specified accumulator is directed to the mirror system. System control base module includes a radio control operation of the Autonomous fotoizluchayuschih panels and a receiving-transmitting antenna communications with the ground segment.

The refusal of one powerful laser by performing photoperiodic panels in the form of a chain of photovoltaic panels that produce energy to power the base module, and Autonomous fotoizluchayuschih panels, each of which includes several low-power fiber lasers with blocks of pumping and feeding their photovoltaic panels, has improved the efficiency, reliability and durability of CSAS as fotoizluchayuschih panels made offline, the failure of the lasers one AFIP does not affect the rest of AFIP and space power in General, is only the loss of some power. Execution photoperiodic panels in a V the e chain of photovoltaic and Autonomous fotoizluchayuschih panels, interconnected actuators made of metal with memory and with the ability to form for disclosure of closed flat zigzag shape, allows one to obtain a compact construction, in contrast, taken as a prototype of SCAS where fotopresentatie panels made by thin-film technology and open with a long astrometry, which also affects the efficiency, reliability and durability of SCAS as thin-film technology provides a low efficiency, large energy losses in the cable network, as well as large size and weight to ensure rigidity. Multiple low-power lasers in each AFIP allowed to use them instead of complex multi-circuit cooling system more simple, such as the base of the frame AFIP in the form of a metallic heat sink plate, which also affects the reliability and weight of the structure. In addition, fotoizluchayuschih panels offline allows to increase the number after Assembly SKIES, and in the course of its operation, which also affects its effectiveness.

Known stand-alone device that converts solar energy into light, consisting of a frame, a device converting solar energy into electrical energy and, mounted inside the frame, on the basis thereof, a control unit, the moustache is the device converting electrical energy into light and United with these devices, energy storage (patent for useful model RU # 110857 from 16.06.2011, B64G 3/00, H01L 33/00, G08G 1/09). In this device converting solar energy into electrical energy through solar panels mounted on the outer surface of the frame, and the device converting electrical energy into light made in view of the Assembly of the laser diode and lens system, the device is used as a signaling device for the detection or tracking of space or down devices, as well as in space geodesy for high-precision goniometric measurements. The disadvantages of this device are the impossibility of its use in space power as photoperiodic elements in SCAS, as the conversion of solar energy into electrical energy through solar panels located on the outer side surface of the frame and the inability to collect them in a large photoprobes panel, for example, for use in solar space power plants, the proposed design, in addition, this device produces a beam with a large angle of divergence of the light and cannot be used for transmission of produced energy from space to the consumer.

The solution, known from the patent RU No. 110857, taken as p is of ototype to the invention, related to Autonomous fotoizluchayuschih panel.

The present invention is directed to the achievement of the technical result consists in expanding the functionality of the device and, accordingly, the scope of its application, in particular in space solar power plants, photoperiodic panels.

The proposed Autonomous fotoizluchayuschih panel, as the closest device contains a frame with a base, a device converting solar energy into electrical energy and, mounted inside the frame, on the basis of the control block, the device converting electrical energy into light and United with these devices, energy storage devices.

To achieve the above technical result, a device converting solar energy into electrical energy mounted within a frame in its upper part, is separated from the lower layer of insulation. Device converting solar energy into electrical energy is a photovoltaic battery, made in the form of a set of optical Fresnel lenses and located in their tricks photoconverters with the system heat sink. The base frame is made of heat sink and connected to the heat sink panels. Device converting electrical energy is GII in light is a fiber lasers with blocks pump and accumulator laser radiation. The solar cells, located in the upper part of the frame, electrically connected across the energy storage unit pumping of fiber lasers and controls AFIP with receiving and transmitting antenna.

The proposed solution allows to use it both as a signaling device for navigation, and, for example, in space solar power plants in photoperiodic panels. The device for converting solar energy into electrical energy in the form of photovoltaic cells and placing it at the top of the frame allows to convert solar energy into electrical energy, while the side faces of the frame are free and can be connected with other similar Autonomous fotoizluchayuschih panels (AFIP), forming a flat design, a large area of any configuration, in particular in SCAS according to the first invention. In this case, since each of AFIP mounted its own low-power fiber lasers with blocks their pumping, respectively, each AFIP not only generates electricity, but also converts it into light and optical fiber can pass it on to the Ground or another object (use in navigation or signal devices), and the sum of the flows from all AFIP (use of SCES) there is the possibility of vyrabatyvat the ü and to transmit a large amount of energy from space to the consumer using a laser beam.

The proposed design AFIP allows its use not only in space but also on Land, geodesy and cartography as a brand with greater efficiency than the prototype, as the location of the photovoltaic cells to convert sunlight into electrical energy in the upper part of the frame, and not on its lateral sides as in the prototype, eliminates shading battery, for example, vegetation, while the transmission of light through a flexible fiber (fiber laser), you can direct the beam in any direction.

Use AFIP as optical lenses, Fresnel lenses, which have a lower mass for the same characteristics in comparison with the classical normal and greater concentration, improves, increases the reliability and efficiency of AFIP. Photovoltaic cells are a heterostructure solar cells, since they have a significantly higher efficiency compared to thin-film fotobravissimo elements, and the energy storage in the form of supercapacitors (the concept of the supercapacitor is common and is found in the technical literature, in particular, see the journal "electronics: Science, Technology, Business, No. 7 in 2009). The framework should consist of carbon in the form of a hexagonal prism, as this mater what al is selected because of its distinctive properties: high strength, lightness, heat resistance, low thermal conductivity, and execution in the form of hexagonal prisms allows for the use of SCAS, to compactly accommodate folded under the fairing, and unfolded to form the figure of a large area with minimal gaps between AFIP. When used in SCAS as one of the options, it is advisable heat sink photoperiodic elements run through the heat sink base frame, for example, in the form of a mesh-core design of the carbon fiber mixed with silicon carbide in the amount of 20%-25% (this ratio provides the optimum balance of stiffness and thermal conductivity of the structure), at the grid nodes which are mounted the panels and rods attached to the nodes on the opposite side of the grid, is connected with the heat sink base frame.

Frame AFIP should be implemented in the form of hexagonal prisms of carbon fiber, the upper end of which is a mesh-rod structure, the cells of which are the Fresnel lens, and the terminals are connected with the heat sink panels. In this case, these rods will serve as stiffeners design.

In addition, the control unit AFIP equipped with a receiving and transmitting antenna for wireless communication using Wi-Fi which allows you to eliminate wires, that simplifies the design and increases its reliability.

The frame 13 of the last in the chain of the photovoltaic panel 5 is connected to the frame 17 (Fig) first Autonomous fotoizluchayuschih panel 6.

More detailed design fotoizluchayuschih panel 6 are presented in figure 3.

Each Autonomous fotoizluchayuschih panel 6 consists of a frame 1 in the form of hexagonal prisms of carbon from the heat sink base 18 and the top face, made in the form of a mesh-rod design (figure 4), in cells which are mounted Fresnel lens 19, the terminals of which are connected with the heat sink 20 of the panels 21, coaxial with the Fresnel lens 19 so that the heat sink 20 is a mesh-rod structure of the carbon fiber mixed with silicon carbide in the amount of 20%-25%, in which the nodes are the panels 21, between which is laid a layer of insulating material 22, and the rods 23 are connected with the heat sink base 18 of the frame 17, in addition, inside the frame 17, on the basis of 18, are mounted the energy storage 24, the control unit 25 fotoizluchayuschih panel 6 with a receiving and transmitting antenna 26, a device converting electrical energy into light, in the form of fiber lasers with 27 blocks the pump 28 and the adder 29 (see figure 5), while the solar cells 21 are electrically connected with the blocks of the pump 28 and the control unit 25 through the energy storage devices 24, in addition, the remote transmission of energy is also supplied by the adder 3 laser radiation, and the adders 29 each fotoizluchayuschih panel 6 is connected to the adder 3 system for remote transmission of energy through a fiber optic cable 30, and the adder 3 is aimed at the mirror system 2, the system control base mod is La 8 includes a radio transmitter 9 control operation of the Autonomous fotoizluchayuschih panels 6 and the receiving-transmitting antenna 10 and the ground segment.

Space solar power plant operates as follows.

After removal of SKIS into orbit, on command from the ground control station there is an opening photoperiodic panel 4 according to a certain algorithm and the alignment of each flat in a closed zig-zag shape. Then there is the transmission of information to the base module 1 wireless (Wi-Fi) on the status of each disclosure fotoprogramma panel 4, and the transmission of information about the internal state of each AFIP 6 (5) (temperature - the temperature sensors 31, the integrity of the cables - current sensors 32, the charging of supercapacitors 24-capacitive sensors 33, the integrity of the fiber - photosensors 34 and the functioning of the control unit 25 AFIP 6). Then comes the installation of the radio channel by receiving and transmitting antenna 10 and the ground segment and the transmission of information about the state of SCAS.

When SKIES is illuminated part of the orbit, the electric current generated by the solar cells 21 AFIP 6, charges the capacitor 24 and, in parallel, is the power blocks pump 28, for example, in the line of diode lasers used for pumping fiber lasers 27. The number of fiber lasers 27 may vary, based on the optimal ratio of the number of transmitted energy and provide sufficient t is pleated base 18 for normal operation of AFIP. Further, in the adder 29 each fotoizluchayuschih panel 6 is the sum of the flows from each laser 27. The optical fiber 30 from each fotoizluchayuschih panel 6 radiation comes to the adder 3, directed to the mirror system 2 remote power transmission SKIES, whence it is transmitted to the ground segment of the reception and conversion of laser radiation into electrical energy.

When space solar power plant is located on the unlit side of the orbit, the electric current required to power the control unit 25 AFIP 6 blocks and pump 28 made, for example, in the form of laser diode bars, produced from energy storage devices 24, such as supercapacitors.

The panels 15 photovoltaic panels 5 of converting solar energy into electrical energy and is electrically connected to the power supply system 12 with energy storage devices (not shown) of the base module 1 and the produced energy is directed to the power steering control computer 8.

In the process of SCAS requests from the Earth to the basic module 1 about checking the status of the Autonomous fotoizluchayuschih panels 6, the request is transmitted to the control unit 25 AFIP 6 by means of wireless communication (radio transmitter 9 of the base module 1 - receiving-transmitting antenna 26 of each AFIP 6), if one of AFIP 6 (or som is to) fail, the control unit 8 will give the team on their trip and all SCAS will continue to work, albeit with lower efficiency, due to the implementation fotoizluchayuschih panels 6 offline. As each AFIP have several low power lasers 27, teplootdelenie provides the base 18 of the frame 17 (for example, in the form of a metal plate, the heat dissipation system will be more reliable and easy, and also the exclusion of a powerful laser from the base module, eliminates the complicated system of the heat sink base module, which also affects the efficiency SKIES.

The proposed Autonomous fotoizluchayuschih panel, functional scheme is shown in Fig.6, and the design of the layers 7, consists of a frame 1 with a base 2, device 3 conversion of solar energy into electrical energy (6) and mounted inside the frame 1, on the basis of 2, a control unit 4, unit 5 (6) conversion of electrical energy into light and United with the specified devices 3, 5 and the control unit 4 of the energy storage 6. Device 3 conversion of solar energy into electrical energy mounted within the frame 1, in its upper part and is separated from the lower layer of insulation 7. The device 3 is a photovoltaic battery, made in the form of a set of optically the Fresnel lens 8 and located at their tricks photoconverters 9 with the heat sink 10. The base 2 of the frame 1 is made of heat-removing, for example, in the form of a metal plate and connected to the heat sink 10 panels 9. The device 5 conversion of electrical energy into light is mounted on the heat sink base 2, fiber lasers 11 blocks the pump 12 and the adder 13 of the laser radiation. The control unit 4 includes a receiving-transmitting antenna 14 (6) and is also installed on the heat sink base 2. The number of installed lasers, selected on the basis of specific tasks. The panels 9, located in the upper part of the frame 1, is electrically connected across the energy storage devices 6 mounted on the heat sink base 2, with blocks of pump 12 fiber lasers 11 and the control unit 4. As one of the possible options presented to the system heat sink 10 of the solar cells 9, which is made in the form of a mesh-core design of the carbon fiber mixed with silicon carbide in the amount of 20%-25%on the grid nodes which are mounted the panels 9 and the rods attached to the nodes on the opposite side of the grid, is connected with the heat sink base 2. The frame 1 is made of carbon fiber, as this material is selected because of its distinctive properties: high strength, lightness, heat resistance, low is epoprostenol. Implementation in the form of a hexagonal prism is represented as one of the embodiments. Photovoltaic cells 9 are heterostructure solar cells, since they have a significantly higher efficiency compared to other fotobravissimo elements. The energy storage 6 made in the form of supercapacitors.

Frame 1 Autonomous fotoizluchayuschih panel made in the form of hexagonal prisms of carbon fiber, the top>Retz which is a mesh-rod structure 15, in grid cells which are the Fresnel lens 8, and the terminals are connected with the heat sink panels and serve to ensure the rigidity of the structure.

Autonomous fotoizluchayuschih panel works as follows.

AFIP oriented in space so that the sun's rays fall perpendicular to the surface of the Fresnel lens 8. After focusing the light rays fall on the active surface of the solar cells 9, which carry the direct conversion of solar energy into electrical energy and transfer it through the energy storage 6 units in pump 12. The pumping units 12 activate the fiber laser 11, the light energy which is transmitted through the fiber to the adder 13. Part of the energy from the energy storage 6 Postup is no power control unit 4. Using the receiving-transmitting antenna 14 to the control unit 4 receives commands about checking the status of AFIP. (temperature - the temperature sensors 16, the integrity of the cables - current sensors 17, the charge of the capacitor 6 capacitive sensors 18, the integrity of the fiber - photosensors 19 and the functioning of the control unit 4 AFIP). After the control unit 4 surveyed all systems to be verified, the information is transmitted back to the control point. If all systems are functioning properly, the control command is issued to activate AFIP. If AFIP you have a problem, the control unit 4 automatically sends information about the malfunction AFIP to the control unit, after which the control command is issued to disconnect the faulty AFIP.

As a signaling device, the proposed AFIP will work similarly to the device, taken as a prototype, i.e. when the spacecraft that has AFIP as a signaling device, is located on the illuminated part of the orbit, solar light focused by the Fresnel lens, is converted into electricity by the solar cells 9 AFIP, which charges the capacitor 6 and, in parallel, is the power blocks pump 12, for example, in the line of diode lasers used for pumping fiber lasers 11. Further, in the adder 13 proshtudirovali flows from each of the laser 11.

When the spacecraft on the unlit side of the orbit, the electric current required to power the control unit 4 AFIP and blocks the pump 12, made for example in the form of laser diode bars, produced from energy storage devices 6, such as supercapacitors.

High-precision determination of the angular coordinates of the spacecraft is as follows: after the start of AFIP, the signal device included in the control unit (formed depending on the problems to be solved) is pulse modulated signal. The nature of the light signal device may be supplemented by the encoding duration and frequency of outbreaks (provided by the encoding device control unit)that will allow confident identification of a space object of artificial origin.

Modern ground-based optical monitoring tools allow you to confidently observe coded signals of this device.

Installation on Board the spacecraft source directed at the observer, the optical radiation can guarantee the detection of an object and its quality position measurements. For example, AFIP as the light source, mounted on the feed beam antenna (IT) spacecraft, will Shine in the same direction,which is directed antenna, and optical instrument, located usually near the ground, point the radio will receive a strong enough luminous flux, so that his registration was confident.

All spacecraft in the radio channel have IT. When the characteristic size of the pattern IT is about degrees requires a system with the same accuracy, so installing on the outer (outside) part of the feed antenna proposed AFIP in the role of Autonomous signaling device allows the use of a narrow light beam.
