Description

Technical Field

[0001] This invention relates to the field of aerial wind power generation technology, and more specifically to a tethered airship-type high-altitude wind power generation system with an integrated wing-mounted and levitated layout. Background Technology

[0002] Wind energy is a renewable and clean natural resource. The wind energy contained in the upper atmosphere exceeds 100 times the total energy demand of humankind. Wind direction is stable within an altitude range of 1km to 15km, and wind energy density increases with altitude (0.25–0.37 W / m³ for every 1m increase in altitude). 2 The better the stability, especially in the upper-level jet stream zone of 8km to 12km where the annual wind speed reaches 30m / s to 50m / s (for every doubling of wind speed, the wind energy density increases sevenfold), the better the duration, stability, and quality of wind power generation. Upper-level wind energy is a clean energy source with excellent development prospects.

[0003] Currently, the development and utilization of high-altitude wind energy mainly involves three technological approaches: tethered kite-type technology systems (including paragliders and parachute-ladder combinations), tethered aircraft-type technology systems (including airborne power generation and ground-based power generation), and tethered aerostat-type technology systems (including power generation payload pods and integrated power generation payload and capsule types). Among these, the tethered kite-type and tethered aircraft-type technology systems, from product development to testing and verification, primarily operate at altitudes below 1 km (wind energy density 500 W / m³). 2 The following (below 3km altitude, which is actually considered low altitude) technical routes have inherent drawbacks, including difficulties in safe and reliable launch and recovery, complex control (prone to falling if out of control), short continuous loiter time, and weak load-carrying capacity (very limited flight altitude, single-unit power generation is only in the hundreds of kW range). They can only utilize unstable low-altitude wind energy resources, and the annual available power generation time is low (around 2200 hours). In contrast, high-altitude air density is moderate, buoyancy efficiency is high (net buoyancy of 0.34kg to 0.77kg per cubic meter of volume), making it particularly suitable for tethered aerostat technology systems. These technologies can safely and stably take off and be recovered and maintained using static buoyancy (easily achieved by simply dragging the tethering cable with a ground winch), have long-term stable loiter time, and are easy to control (basically no active flight control is required). They also have huge potential for load-carrying capacity. These advantages allow for the full development and utilization of abundant high-altitude wind energy resources (especially in the jet stream area at 10,000 meters altitude, where uninterrupted and stable power generation can last for the whole year).

[0004] The tethered aerostat-type high-altitude wind power generation system, which combines dynamic lift and static buoyancy, generates a large load-carrying capacity while reducing its own size, thus achieving high-altitude, low-cost, and high-power wind power generation. The system transmits electrical energy to the ground via tethered cables.

[0005] However, there are currently few tethered aerostat wind power generation technologies with integrated wing-and-float layouts, and all of them have technical problems. For example, patent application number 200710304161.X, entitled "Balloon-suspended High-altitude Wind Power Generation Equipment," describes a tethered aerostat that lifts wind power equipment into the air to generate electricity. Its front part has a large horizontal wing auxiliary group to provide dynamic lift, while the rear part has a small tail fin. The lift generated by the horizontal wing causes a large unstable pitching moment, and the small tail fin area cannot provide sufficient stabilizing restoring moment, thus failing to achieve overall aerodynamic stability. Another example is patent application number 201880024606.5, entitled "High-altitude Wind Power Station Tethered to the Ground," which describes a wing-like structure with wing-like components on all sides. Using a thin-layered airbag to provide buoyancy (filled with helium, the buoyancy volume is small, and the static buoyancy is very limited) is essentially a tethered aircraft technology, which has the inherent drawbacks of tethered aircraft. The core of the invention patent application number 201610326323.9, entitled "A High-Altitude Hot Aircraft Wind Power Generation System", describes a semi-rigid hot aircraft with wings, which is supported by a rigid frame and wrapped with a flexible airbag material (filled with air). Initially, it is powered by ground power and heats the air through multiple combustion furnaces to provide static buoyancy, which drives the wind turbine blades to rotate in the opposite direction to provide power for take-off. The system is complex to operate, has excessive weight, and once the power supply system fails, buoyancy cannot be generated, and the system is prone to falling and damage. It is suitable for low altitudes of 500m to 800m.

[0006] In addition to existing deficiencies in system aerodynamic stability, load-bearing capacity, and flight altitude, the current technology for tethered aerostat-type high-altitude wind power generation systems with integrated wing-and-float layouts still faces the following three common problems that need to be solved in practical engineering applications:

[0007] 1) Adaptability to complex high-altitude environments has not yet been considered.

[0008] Complex environmental factors at high altitudes include alternating day and night temperatures (caused by direct sunlight and cloud scattering during the day, and ground infrared radiation at night; requiring the system's airbags to expand under heat during the day to ensure overpressure safety, and to contract under cold at night to maintain buoyancy and prevent altitude loss), prolonged strong winds and short-term gusts or shear winds (requiring structural safety and high wind resistance), rain / snow / icing / lightning (requiring the system to prevent water accumulation, snow accumulation, icing, and lightning), short-term cold clouds / cold currents (requiring the system to maintain buoyancy and prevent altitude loss), safe ecological environment for seasonal bird migration (requiring the system to have the ability to detect birds and automatically drive them away), and safe transportation environment for civil aviation routes (requiring the system to have the ability to automatically respond to air traffic control services). These are issues that the tethered aerostat-type high-altitude wind power generation system must consider and solve as a friendly new energy power station infrastructure (20-year design life), and are the basic requirements for the engineering and practical application of this technology system.

[0009] 2) The problem of stable power generation during long-term loitering has not yet been solved.

[0010] Abundant high-altitude wind energy resources have provided the objective environmental conditions for stable wind power generation. However, the long-term aloft stay of tethered aerostats (vehicle platforms, with relatively mature wind turbine technology) has become a key technological bottleneck, involving three aspects: First, existing technologies all use high-pressure airbags (filled with helium) to provide the necessary static buoyancy and maintain aerodynamic stiffness. In practical applications, due to the alternating day and night temperatures at high altitudes, the helium inside the airbag needs to be kept at low pressure at night to maintain its shape (maintaining buoyancy but with lower stiffness), while it is heated during the day to generate high pressure (thousands of Pascals), which poses a challenge for lightweight airbags. The material requirements are high, the process is difficult, and the cost is high. Secondly, it is limited by the leakage loss of helium inside the airbag (the leakage mass rate is proportional to the square root of the product of the atmospheric pressure at the altitude and the pressure difference inside and outside the airbag). Due to the high atmospheric pressure at high altitude (tens of thousands of Pascals) coupled with the high pressure of the airbag, helium leakage is relatively fast (online replenishment of large amounts of helium is not feasible), resulting in a loitering time of only a few months (a significant gap from the 20-year loitering lifespan). Finally, the long-term loitering requires weak control of the adaptive environment (passive control, no complex operation required), and is unattended.

[0011] 3) There is still a gap between low cost and independent control.

[0012] Lightweight, high-strength airbag materials and helium are the main cost sources for tethered aerostat-type high-altitude wind power generation systems, accounting for up to 70%. Currently, to adapt to the complex high-altitude environment, existing technologies require high-pressure airbags with high performance requirements such as lightweight (low surface density), high strength, airtightness, resistance to tearing, and resistance to aging. This presents significant technical challenges and high costs (generally reaching 700 yuan / linear meter). Meanwhile, helium is expensive in my country, with supply falling short of demand, keeping prices high.

[0013] Therefore, providing a tethered airship-type high-altitude wind power generation system with an integrated wing-mounted and levitated layout is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0014] In view of this, the present invention provides a tethered airship type high-altitude wind power generation system with an integrated flying wing and levitation layout, in order to solve the problems of insufficient system aerodynamic stability, load capacity and flight altitude in the existing technology, as well as the problems of adaptability to complex high-altitude environments, stable power generation during long-term loiter, low cost and autonomous controllability in practical engineering applications.

[0015] To achieve the above objectives, the present invention adopts the following technical solution:

[0016] A tethered aerostat-type high-altitude wind power generation system with an integrated wing-and-buoyancy layout includes an air-to-air aerostat wind power generation system, an air-to-ground power transmission and tethering cable, and a ground anchoring system. The air-to-air aerostat wind power generation system is connected to the ground anchoring system via the air-to-ground power transmission and tethering cable. The air-to-air aerostat wind power generation system includes a wing structure and multiple wind turbine generators. The wing structure includes a thin-walled truss load-bearing structure with a wing configuration, multiple buoyancy airbags, multiple tail fins, and skin components. The thin-walled truss load-bearing structure has multiple constraint spaces distributed along the wingspan direction; multiple buoyancy airbags are respectively arranged in the multiple constraint spaces; multiple tail fins are respectively arranged at both ends of the rear part of the flying wing configuration thin-walled truss load-bearing structure; the skin component is fitted onto the flying wing configuration thin-walled truss load-bearing structure and the two tail fins to form a physical gap channel between the skin component and the buoyancy airbags; multiple wind turbine generators are installed at the bottom of the flying wing configuration thin-walled truss load-bearing structure through a support structure.

[0017] By adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0018] This invention combines the advantages of both tethered aerostat (static buoyancy) and tethered aircraft (dynamic lift) technologies, generating a large load-carrying capacity while reducing its own size, thus achieving high-altitude, low-cost, and high-power wind power generation.

[0019] Furthermore, the flying wing configuration thin-walled truss load-bearing structure is either a swept-back wing or a straight wing.

[0020] Furthermore, the flying wing configuration thin-walled truss load-bearing structure includes multiple airfoil planar load-bearing truss structural units and multiple spanwise truss structures. Multiple airfoil planar load-bearing truss structural units, evenly distributed along the spanwise direction, are connected together by multiple spanwise truss structures distributed along the spanwise direction. Each airfoil planar load-bearing truss structural unit includes a cross-section airfoil truss structure and multiple vertical constraint trusses. The multiple vertical constraint trusses are arranged inside the cross-section airfoil truss structure and spaced longitudinally. The multiple spanwise trusses are respectively connected to both ends of the cross-section airfoil truss structure and the upper and lower ends of the vertical constraint truss located in the middle, forming multiple constraint spaces distributed along the spanwise direction. Multiple tail fins are respectively arranged at the rear of the cross-section airfoil truss structure or arranged at the rear of the cross-section airfoil truss structure through extension support trusses. The skin component is fitted onto the multiple cross-section airfoil truss structures and multiple spanwise truss structures. Multiple wind turbine generators are respectively connected to the bottom of the multiple cross-section airfoil truss structures through the support structure.

[0021] Furthermore, the skin component includes multiple outer skins, multiple sealing zippers, and multiple tail fin skins. The number of outer skins is one more than the number of cross-sections of the wind turbine generator set. The multiple outer skins are sequentially fitted onto the multiple cross-section airfoil truss structures and the multiple spanwise truss structures along the spanwise direction, and the joints of two adjacent outer skins correspond to the circumferential cross-section positions of the vertical constraint truss. Adjacent outer skins are connected by the sealing zippers. The multiple tail fin skins respectively cover the multiple tail fins.

[0022] Furthermore, the airfoil truss structure, the vertical constraint truss, the spanwise truss structure, and the tail fin are all assembled from lightweight, high-strength composite material components; the outer skin is a lightweight, micro-permeable, flexible film material.

[0023] Furthermore, the lightweight high-strength composite material components are coated with a low absorption-to-emission ratio coating or a total reflection coating or covered with an aluminum film on the contact surfaces of the outer skin and the buoyancy airbag.

[0024] Furthermore, the support structure includes multiple connecting support trusses and multiple support hoisting trusses, and multiple wind turbine generators are connected through multiple connecting support trusses; the connection points of two adjacent connecting support trusses are all connected to the bottom of the corresponding airfoil truss structure through the support hoisting truss; multiple cameras and vibration measuring devices are installed on the support hoisting truss structure.

[0025] Furthermore, the aforementioned tethered aerostat-type high-altitude wind power generation system with integrated wing-mounted and floating layout also includes multiple dual-redundant active valves, multiple heat pumps, and multiple blowers. Heating film strips are laid on the leading edge of the airfoil truss structure, the spanwise truss structure located at the front, and the leading edge of the tail fin. The outer skin located at the leading edge of the airfoil truss structure has multiple openings. The multiple dual-redundant active valves are respectively installed on the leading edges of the multiple airfoil truss structures and correspond to the positions of the multiple openings. The multiple heat pumps are respectively installed in the middle of the multiple vertical constraint trusses and located inside the outer skin. The multiple blowers are respectively fixed on the two spanwise truss structures located in the middle and close to the vertical constraint trusses. Each blower penetrates the outer skin.

[0026] Furthermore, the aforementioned tethered airship-type high-altitude wind power generation system with integrated wing-mounted and floating layout also includes lightning protection rods, lightning rods, and lightning protection cables. The lightning protection rods are respectively fixed to the top of multiple airfoil truss structures; the lightning rods are respectively fixed to the top of the tail fin; and the lightning protection cables are laid on the lightning protection rods and their extension ends are respectively connected to the lightning rods.

[0027] Furthermore, the aforementioned tethered airship-type high-altitude wind power generation system with integrated wing-shaped and floating layout also includes a first equipment compartment and a second equipment compartment. A triangular bracket is fixed to the bottom front end of the airfoil truss structure located in the middle position, and the first equipment compartment is installed on the triangular bracket. The second equipment compartment is installed on the top of the airfoil truss structure located in the middle position and is located inside the outer skin.

[0028] Furthermore, there are multiple flying wing structures, which are arranged at intervals from top to bottom and connected sequentially by connecting trusses.

[0029] The application of the above-described flying wing-integrated tethered airship-type high-altitude wind power generation system, by carrying communication base stations, navigation, earth observation, meteorological monitoring, early warning detection, and jamming countermeasures payloads, is applied in the fields of communication relay, navigation enhancement, high-resolution earth observation, extreme weather monitoring, early warning detection, and electronic countermeasures.

[0030] Therefore, the present invention provides a tethered aerostat-type high-altitude wind power generation system with an integrated wing-shaped buoyancy design. Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1) The outer skin, flying wing configuration thin-walled load-bearing truss structure and multiple buoyancy airbags constructed in this scheme form a rigid-flexible hybrid stable load-bearing structure system. By combining dynamic lift and static buoyancy, it generates a large load-bearing capacity while reducing its own volume. The technical route has high scalability, and the power generation of a single unit can reach several megawatts to ten megawatts. It can efficiently develop and utilize high-altitude wind energy (especially the jet stream area at an altitude of 10,000 meters).

[0032] 2) It can safely withstand long-term strong winds and short-term gusts or shear winds without losing stability. The internal buoyancy airbags and the external skin are connected by a thin-walled load-bearing truss structure with a flying wing configuration to establish a stable physical gap channel (filled with air). This allows the internal buoyancy airbags to always operate in a zero-pressure state (ensuring that the buoyancy gas is basically leak-free). It can also freely breathe and deform (expand and contract) with the changing day and night temperatures of the external environment. The ram air (receiving strong winds after the dual-redundant active valve is opened) + the blowing phenomenon formed by the micro-permeable external skin material can effectively repel water, prevent snow accumulation, and prevent icing. With the heating film, dual-redundant active valve, blower, heat pump and other heating of the internal gas circulation, it can efficiently melt ice, melt snow, dry and maintain buoyancy. In addition, the first equipment compartment can effectively support air traffic control and provide warnings without interfering with the safety of civil aviation routes. It can also detect and drive away approaching flocks of birds in a timely manner and protect the aerial ecological environment. It has good adaptability to complex high-altitude environments.

[0033] 3) The ram air and micro-permeable outer skin material create an air pressure difference, naturally maintaining a certain internal and external pressure on the outer skin, ensuring the smoothness (low drag) of the outer skin's flying wing configuration, and forming a continuous purging phenomenon on its surface, which can improve the lift-to-drag ratio of the flying wing configuration (flow control technology). The tail fin and the aerodynamic shape of the flying wing configuration constitute a low-drag, high-lift-to-drag ratio, pitch and roll attitude self-stabilization, and autonomous heading into the wind aerodynamic layout, enabling unattended operation during long-term loiter, simple operation, and stable stationary power generation.

[0034] 4) The rigid-flexible hybrid stable load-bearing structure system maintains the flying wing configuration, allowing the buoyancy airbag to work in a zero-pressure state. The outer skin is only used for rectification and providing buoyancy volume (with very low pressure requirements). The performance requirements of the flexible thin film multilayer composite material (such as tensile strength, tear strength, elongation at break, air tightness, etc.) are greatly reduced, making it easy to achieve low-cost production and alternative selection.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1:

[0049] like Figure 1-4As shown in Figure 9, this embodiment of the invention discloses a tethered aerostat-type high-altitude wind power generation system with an integrated wing-shaped floating layout. It includes an airborne aerostat wind power generation system 1, an air-to-ground power transmission and tethering cable 2, and a ground anchoring system 3. The airborne aerostat wind power generation system 1 is connected to the ground anchoring system 3 via the air-to-ground power transmission and tethering cable 2. The airborne aerostat wind power generation system 1 stably captures wind energy and converts it into electrical energy, which is then anchored and fixed to the ground via the air-to-ground power transmission and tethering cable 2. The collected electrical energy is directly connected to the grid, used for power supply, or stored. The mid-aircraft wind power generation system 1 includes a flying wing structure and multiple wind turbine generators 15. The flying wing structure includes a flying wing-configured thin-walled truss load-bearing structure 11, multiple buoyancy airbags 12, multiple tail fins 13, and skin components 14. In this embodiment, the flying wing-configured thin-walled truss load-bearing structure 11 has a swept-back airfoil shape and multiple constraint spaces distributed along the wingspan direction. The multiple buoyancy airbags 12 are respectively arranged in the multiple constraint spaces, and the buoyancy airbags 12 are filled with lightweight buoyancy gas, which can be used in the experimental verification stage. Helium and hydrogen mixed with other safe gases can be used in the engineering application stage to achieve low cost and autonomous control. Multiple tail fins 13 are respectively arranged at both ends of the rear of the thin-walled truss load-bearing structure 11 of the flying wing configuration, providing aerodynamic restoring torque. Together with the aerodynamic shape of the flying wing configuration, they form an aerodynamic layout with low drag, high lift-to-drag ratio, self-stabilized pitch and roll attitude, and autonomous heading into the wind. Skin components 14 are fitted onto the thin-walled truss load-bearing structure 11 of the flying wing configuration and the two tail fins 13, forming a physical gap channel between the skin components 14 and the buoyancy airbags 12, thus enabling buoyancy... The airbag 12 operates in a zero-pressure state, freely expanding and contracting according to the alternating day and night temperatures of the external environment. This means the buoyancy airbag 12 provides static buoyancy. Functionally redundant and highly safe, the zero-pressure operating mode minimizes leakage of the buoyant gas, maintaining long-term buoyancy and reducing performance requirements for the airbag material's airtightness, strength, and processing technology. This facilitates low-cost production and is not limited by the choice of airbag material or configuration. Multiple wind turbine generators 15 are mounted at the bottom of the wing-shaped thin-walled truss load-bearing structure 11 via a support structure 16. This invention combines the synergistic advantages of tethered aerostat (static buoyancy) and tethered aircraft (dynamic lift) technologies, generating significant load-bearing capacity while reducing its own size, achieving high-altitude, low-cost, high-power wind power generation.

[0050] Specifically, when there are multiple air-to-ground power transmission and mooring cables 2, multiple air-to-ground power transmission and mooring cables 2 are fitted with load-bearing slip rings 4 on the side near the air-to-ground wind power generation system 1 of the air-to-ground aerostat.

[0051] Specifically, the flying wing configuration thin-walled truss load-bearing structure 11 includes multiple airfoil planar load-bearing truss structural units 111 and multiple spanwise truss structures 112. The multiple airfoil planar load-bearing truss structural units 111, evenly distributed along the spanwise direction, are connected together by multiple spanwise truss structures 112. In this embodiment, the number of airfoil planar load-bearing truss structural units 111 is 5. Each airfoil planar load-bearing truss structural unit 111 includes a cross-section airfoil truss structure 1111 and multiple vertical constraint trusses 1112. In this embodiment, the number of vertical constraint trusses 1112 is 3, and the multiple vertical constraint trusses 1112 are arranged on the cross-section airfoil truss structure. The frame structure 1111 is internally and longitudinally spaced, with multiple spanwise truss structures 112 connected to the two ends of the airfoil truss structure 1111 and the upper and lower ends of the vertical constraint truss 1112 located in the middle, to form multiple constraint spaces distributed along the wingspan direction. In this embodiment, four constraint spaces are formed. Multiple tail fins 13 are respectively arranged at the rear of the airfoil truss structure 1111, and each tail fin 13 may be equipped with a rudder surface. Skin components 14 are fitted onto the multiple airfoil truss structures 1111 and the multiple spanwise truss structures 112. Multiple wind turbine generators 15 are connected to the bottom of the multiple airfoil truss structures 1111 through support structures 16.

[0052] Specifically, the skin component 14 includes multiple outer skins 141, multiple sealing zippers 142, and two tail fin skins. The number of outer skins 141 is one more than the number of cross-sections of the wind turbine generator set 15. In this embodiment, there are four outer skins 141. The four outer skins 141 are sequentially fitted onto multiple cross-section airfoil truss structures 1111 and multiple spanwise truss structures 112 along the spanwise direction, and the joints of two adjacent outer skins 141 correspond to the circumferential cross-sections of the vertical constraint truss 1112. All 1 are connected by sealed zippers 142, which facilitates non-destructive disassembly and maintenance during subsequent assembly and recycling. In addition, several strip-shaped curtain interfaces are provided at the contact points between the outer skin 141 and the cross-section airfoil truss structure 1111, as well as between the outer skin 141 and the spanwise truss structure 112, to form a complete smooth duct configuration aerodynamic shape; multiple tail wing skins are respectively covered on multiple tail wings 13 and connected to the adjacent outer skin 141 as a whole. In this embodiment, both the outer skin 141 and the tail wing skin are lightweight, micro-permeable, flexible film materials.

[0053] Specifically, the cross-section airfoil truss structure 1111, the vertical constraint truss 1112, the spanwise truss structure 112, and the tail fin 13 are all spliced ​​together using lightweight high-strength composite material components to form a large-span, three-dimensional, thin-walled, stable load-bearing structure system in the shape of a flying wing. The lightweight high-strength composite material components are made of carbon fiber tubing, aluminum alloy tubing, high-pressure flexible air columns, or a combination thereof. In this embodiment, carbon fiber tubing is selected to reduce cost and weight.

[0054] Specifically, the lightweight, high-strength composite material components are coated with a low absorption-to-emission ratio coating or a total reflection coating or covered with an aluminum film on the contact surfaces of the outer skin 141 and the buoyancy airbag 12, which can prevent the components from heating up and damaging the strength of the flexible composite material in contact with them.

[0055] Specifically, the support structure 16 includes multiple connecting support trusses 161 and multiple supporting hoisting trusses 162. Multiple wind turbine generator sets 15 are connected through the multiple connecting support trusses 161. The connection points of two adjacent connecting support trusses 161 are all connected to the bottom of the corresponding airfoil truss structure 1111 through the supporting hoisting truss 162. Thus, the wind turbine generator set 15 can be hoisted in the airfoil with high rigidity and stably capture wind energy. In particular, the structural rigidity under strong winds will not produce swaying or fluttering. In this embodiment, the wind turbine generator set 15 includes a three-bladed propeller and a diffuser duct, which are integrated into one unit. The front and rear blades rotate in opposite directions, which can counteract the effect of the reverse torque generated by the blades.

[0056] Specifically, the airfoil truss structure 1111, the vertical constraint truss 1112, the spanwise truss structure 112, and the tail fin 13 are all spliced ​​together using lightweight high-strength composite material components. The airfoil truss structure 1111, the vertical constraint truss 1112, the spanwise truss structure 112, and the tail fin 13 are connected and woven into a large-span three-dimensional flying wing configuration thin-walled stable load-bearing structure system. The lightweight high-strength composite material components are carbon fiber tubes, aluminum alloy tubes, high-pressure flexible air columns, or a combination thereof. In this embodiment, carbon fiber tubes are selected to reduce cost and weight.

[0057] To further optimize the technical solution of the present invention, the lightweight high-strength composite material components are coated with a low absorption-to-emission ratio coating or a total reflection coating or covered with an aluminum film on the contact surfaces of the outer skin 141 and the buoyancy airbag 12, which can prevent the components from heating up and damaging the strength of the flexible composite material in contact with them.

[0058] To further optimize the technical solution of the present invention, a tethered airship-type high-altitude wind power generation system with an integrated wing-mounted and floating layout also includes multiple dual-redundant active valves 5, multiple heat pumps, and multiple blowers 6. Heating film strips are laid on the leading edge of the airfoil truss structure 1111, the forward spanwise truss structure 112, and the leading edge of the tail fin 13 to achieve de-icing functionality. The outer skin 141 located at the leading edge of the airfoil truss structure 1111 has multiple openings, and the multiple dual-redundant active valves 5 are respectively installed on multiple... The leading edge of the airfoil truss structure 1111 has multiple openings. In this embodiment, there are five dual-redundant active valves 5, corresponding to five openings. Multiple heat pumps are installed in the middle of multiple vertical constraint trusses 1112 and located inside the outer skin 141. Multiple blowers 6 are fixed on two spanwise truss structures 112 located in the middle and close to the vertical constraint trusses 1112. Each blower 6 penetrates the outer skin 141 and includes four blowers arranged in a matrix. During operation, the blowers have two operating modes (based on the travel position of the controller's solenoid valves): one is to open the outer skin valve and close the internal valve, forming an air intake and exhaust channel between the outer skin 141 and the airfoil; the other is to close the outer skin valve and open the internal valve, forming an airflow channel between the airfoil inside the outer skin 141. When the dual-redundant active valve 5 is opened, the ram air generated by the strong wind in the air can enter the truss space inside the flying wing, forming an air pressure difference. This naturally maintains a certain internal and external pressure on the outer skin 141, ensuring the smoothness (low drag) of the flying wing configuration of the outer skin 141. At the same time, it provides a zero-pressure working environment for the internal buoyancy airbag 12. Combined with the micro-permeability of the outer skin 141, a continuous purging phenomenon is formed on its surface, which can improve the lift-to-drag ratio of the flying wing configuration (flow control technology) and prevent snow accumulation and water dripping on the outer skin. Additionally, if the ambient wind speed is low and the ram air capacity is insufficient, the dual-redundancy active valve 5 can be closed, and the air intake and exhaust channels of the blower outer skin and the flying wing can be opened. The high-flow blower can actively draw in external ambient air to achieve the above functions (redundancy design, safe and reliable). When there are short-term cold clouds / cold currents in the air or when there is a large area of ​​snow or ice accumulation on the outer skin (leading to insufficient system buoyancy or increased weight, and risk of decreased hang time) or when the humidity of the gas inside the flying wing is too high, the heat pump can be turned on, and the air circulation channel inside the blower can be opened to accelerate the internal air heat exchange efficiency, improve the overall temperature level of the gas inside the flying wing, and improve the system buoyancy, the ability of the outer skin 141 to melt ice and snow, and dry the internal gas.

[0059] To further optimize the technical solution of the present invention, a flying wing-mounted integrated layout tethered airship type high-altitude wind power generation system also includes a lightning protection rod 7, a lightning rod 8, and a lightning protection cable 9. The lightning protection rod 7 is fixed to the top of multiple cross-section airfoil truss structures 1111; the lightning rod 8 is fixed to the top of the tail fin 13; the lightning protection cable 9 is laid on the lightning protection rod 7 and its extension end is connected to the lightning rod 8, thereby forming a Faraday cage lightning protection barrier. In the event of a lightning strike, it can attract lightning and transmit it to the ground for discharge along with the air-to-ground power transmission and the tethered cable 2, protecting the airship and the equipment on it.

[0060] To further optimize the technical solution of the present invention, a tethered airship-type high-altitude wind power generation system with an integrated wing-shaped and levitating layout also includes a first equipment compartment 101 and a second equipment compartment 102. A triangular bracket is fixed to the bottom front end of the cross-sectional airfoil truss structure 1111 located in the middle position. The first equipment compartment is mounted on the triangular bracket. The first equipment compartment 101 provides the air pressure, temperature, and installation environment required for the reliable operation of the internal equipment. The internal equipment includes at least wind sensors, transponders, anti-collision lights, and bird detection and deterrence devices. Thus, when the aerial wind power generation system is working normally, it can measure the environmental wind field online, support the online prediction function of power generation, and participate in air traffic control services and provide... The system serves to warn and prevent disruption to civil aviation transport safety, promptly detect and drive away approaching flocks of birds, and protect the aerial ecological environment. The second equipment compartment 102 is installed on top of the cross-section airfoil truss structure 1111 located in the middle and inside the outer skin 114. The second equipment compartment 102 provides the air pressure, temperature, and installation environment required for the reliable operation of the internal equipment. The internal equipment includes at least a combined inertial navigation system, a Beidou positioning and communication terminal, a Tiantong and broadband satellite communication terminal, a barometric altimeter, a differential pressure gauge, and a thermometer. This allows for real-time online monitoring of the position, attitude, air pressure, altitude, differential pressure, temperature, and other information of the aerial wind power generation system. The data is then transmitted to the ground operation and management center via satellite communication telemetry for status monitoring and health management.

[0061] To further optimize the technical solution of the present invention, multiple cameras and vibration measurement devices are installed on the supporting hoisting truss structure 162 to monitor the operating status and vibration of the wind turbine generator 15 in real time, and transmit the data to the ground operation and management center for status monitoring and health management via satellite communication telemetry.

[0062] This invention also discloses an application of the above-mentioned ducted layout rigid-flexible hybrid structure tethered airship type high-altitude wind power generation system. By carrying communication base station, navigation, earth observation, meteorological monitoring, early warning detection, and jamming countermeasure mission payloads, it can be applied to communication relay (also taking into account emergency communication scenarios), navigation enhancement, high-resolution earth observation, extreme weather monitoring (such as typhoons), early warning detection, and electronic countermeasures. Of course, its application to other similar fields is also within the protection scope of this invention.

[0063] Specifically, the air-to-ground power transmission and mooring cable 2 can be woven from high-strength lightweight materials such as high-molecular polyethylene and Kevlar, and can integrate heat-conducting materials (such as air pipes) inside to accelerate the heat dissipation of high-power power transmission cables.

[0064] Specifically, the ground-based mooring system 3 is fixed to the foundation. The aerial aerostat wind power generation system 1 is safely deployed and retrieved via winches and rope-holding machines. A small-capacity energy storage station can be configured nearby to supply power during deployment and retrieval. Simultaneously, a substation can be configured to connect the electricity transmitted via the mooring cables to the grid for power supply or storage. The telemetry and control ground stations are centrally located in the wind farm's operation and management center, exchanging information with the aerial aerostat wind power generation system 1 via satellite wireless links. All ground equipment can be housed in small, fixed buildings to adapt to varying weather conditions and prevent unauthorized entry, thus avoiding safety accidents.

[0065] Example 2:

[0066] like Figure 5-9As shown in the figure, this invention discloses a tethered aerostat-type high-altitude wind power generation system with an integrated wing-shaped floating layout. The system includes an airborne aerostat wind power generation system 1, an air-to-ground power transmission and tethering cable 2, and a ground anchoring system 3. The airborne aerostat wind power generation system 1 is connected to the ground anchoring system 3 via the air-to-ground power transmission and tethering cable 2. The airborne aerostat wind power generation system 1 stably captures wind energy and converts it into electrical energy, which is then anchored and fixed to the ground via the air-to-ground power transmission and tethering cable 2. The collected electrical energy is directly connected to the grid, used for power supply, or stored. The air-to-ground wind power generation system 1 includes a flying wing structure and multiple wind turbine generators 15. The flying wing structure includes a flying wing-configured thin-walled truss load-bearing structure 11, multiple buoyancy airbags 12, multiple tail fins 13, and skin components 14. In this embodiment, the flying wing-configured thin-walled truss load-bearing structure 11 has a straight airfoil shape and multiple constraint spaces distributed along the wingspan direction. The multiple buoyancy airbags 12 are respectively arranged in the multiple constraint spaces, and the buoyancy airbags 12 are filled with lightweight buoyancy gas, such as helium, for example, during the experimental verification stage. In the gas and engineering application stages, hydrogen mixed with a safe gas can be used to achieve low cost and autonomous control. Multiple tail fins 13 are respectively arranged at both ends of the rear of the thin-walled truss load-bearing structure 11 of the flying wing configuration, providing aerodynamic restoring torque. Together with the aerodynamic shape of the flying wing configuration, they form an aerodynamic layout with low drag, high lift-to-drag ratio, self-stabilized pitch and roll attitude, and autonomous heading into the wind. The skin component 14 is fitted onto the thin-walled truss load-bearing structure 11 of the flying wing configuration and the two tail fins 13 to form a physical gap channel between the skin component 14 and the buoyancy airbag 12, so that buoyancy... The airbag 12 operates in a zero-pressure state, freely expanding and contracting according to the alternating day and night temperatures of the external environment. This means the buoyancy airbag 12 provides static buoyancy. Functionally redundant and highly safe, the zero-pressure operating mode minimizes leakage of the buoyant gas, maintaining long-term buoyancy and reducing performance requirements for the airbag material's airtightness, strength, and processing technology. This facilitates low-cost production and is not limited by the choice of airbag material or configuration. Multiple wind turbine generators 15 are mounted at the bottom of the wing-shaped thin-walled truss load-bearing structure 11 via a support structure 16. This invention combines the synergistic advantages of tethered aerostat (static buoyancy) and tethered aircraft (dynamic lift) technologies, generating significant load-bearing capacity while reducing its own size, achieving high-altitude, low-cost, high-power wind power generation.

[0067] Specifically, when there are multiple air-to-ground power transmission and mooring cables 2, multiple air-to-ground power transmission and mooring cables 2 are fitted with load-bearing slip rings 4 on the side near the air-to-ground wind power generation system 1 of the air-to-ground aerostat.

[0068] Specifically, the flying wing configuration thin-walled truss load-bearing structure 11 includes multiple airfoil planar load-bearing truss structural units 111 and multiple spanwise truss structures 112. The multiple airfoil planar load-bearing truss structural units 111, evenly distributed along the spanwise direction, are connected together by multiple spanwise truss structures 112. In this embodiment, the number of airfoil planar load-bearing truss structural units 111 is 5. Each airfoil planar load-bearing truss structural unit 111 includes a cross-section airfoil truss structure 1111 and multiple vertical constraint trusses 1112. In this embodiment, the number of vertical constraint trusses 1112 is 3, and the multiple vertical constraint trusses 1112 are arranged on the cross-section airfoil truss structure 11. The wingspan 11 is internally and longitudinally spaced, with multiple spanwise truss structures 112 connected to the two ends of the airfoil truss structure 1111 and the upper and lower ends of the vertical constraint truss 1112 located in the middle, to form multiple constraint spaces distributed along the wingspan direction. In this embodiment, four constraint spaces are formed. Multiple tail fins 13 are respectively arranged at the rear of the airfoil truss structure 1111 through extension support trusses 113, and each tail fin 13 may have a rudder surface at the rear. Skin components 14 are fitted onto the multiple airfoil truss structures 1111 and multiple spanwise truss structures 112. Multiple wind turbine generators 15 are respectively connected to the bottom of the multiple airfoil truss structures 1111 through support structures 16.

[0069] Specifically, the skin component 14 includes multiple outer skins 141, multiple sealing zippers 142, and two tail wing skins. In this embodiment, there are four outer skins 141, which are sequentially fitted onto multiple cross-section airfoil truss structures 1111 and multiple spanwise truss structures 112 along the wingspan direction. The joints of two adjacent outer skins 141 correspond to the circumferential cross-sections of the vertical constraint truss 1112. Adjacent outer skins 141 are connected by sealing zippers 142. This facilitates non-destructive disassembly and maintenance during subsequent assembly, integration, and recycling. In addition, several strip-shaped curtain interfaces are provided at the contact points between the outer skin 141 and the cross-section airfoil truss structure 1111, as well as between the outer skin 141 and the spanwise truss structure 112, to form a complete smooth duct configuration aerodynamic shape. The two tail wing skins are respectively wrapped around the two tail wings 13 and connected to the adjacent outer skin 141 as a whole. In this embodiment, both the outer skin 141 and the tail wing skin are lightweight, micro-permeable, flexible film materials.

[0070] Specifically, the cross-section airfoil truss structure 1111, the vertical constraint truss 1112, the spanwise truss structure 112, and the tail fin 13 are all spliced ​​together using lightweight high-strength composite material components to form a large-span, three-dimensional, thin-walled, stable load-bearing structure system in the shape of a flying wing. The lightweight high-strength composite material components are made of carbon fiber tubing, aluminum alloy tubing, high-pressure flexible air columns, or a combination thereof. In this embodiment, carbon fiber tubing is selected to reduce cost and weight.

[0071] Specifically, the lightweight, high-strength composite material components are coated with a low absorption-to-emission ratio coating or a total reflection coating or covered with an aluminum film on the contact surfaces of the outer skin 141 and the buoyancy airbag 12, which can prevent the components from heating up and damaging the strength of the flexible composite material in contact with them.

[0072] Specifically, the support structure 16 includes three connecting support trusses 161 and three supporting hoisting trusses 162, with the three wind turbine generators 15 arranged in a triangular pattern. The three wind turbine generators 15 are connected by the three connecting support trusses 161. The connection points of two adjacent connecting support trusses 161 are all connected to the bottom of the corresponding airfoil truss structure 1111 through the supporting hoisting truss 162. This allows the wind turbine generators 15 to be hoisted within the wing with high rigidity and stably capture wind energy, especially under strong winds, preventing swaying and fluttering. In this embodiment, the wind turbine generator 15 includes a three-bladed propeller and a diffuser duct, which are integrated into one unit. The front and rear blades rotate in opposite directions, which can counteract the reverse torque generated by the blades.

[0073] Specifically, the airfoil truss structure 1111, the vertical constraint truss 1112, the spanwise truss structure 112, and the tail fin 13 are all spliced ​​together using lightweight high-strength composite material components. The airfoil truss structure 1111, the vertical constraint truss 1112, the spanwise truss structure 112, and the tail fin 13 are connected and woven into a large-span three-dimensional flying wing configuration thin-walled stable load-bearing structure system. The lightweight high-strength composite material components are carbon fiber tubes, aluminum alloy tubes, high-pressure flexible air columns, or a combination thereof. In this embodiment, carbon fiber tubes are selected to reduce cost and weight.

[0074] To further optimize the technical solution of the present invention, the lightweight high-strength composite material components are coated with a low absorption-to-emission ratio coating or a total reflection coating or covered with an aluminum film on the contact surfaces of the outer skin 141 and the buoyancy airbag 12, which can prevent the components from heating up and damaging the strength of the flexible composite material in contact with them.

[0075] To further optimize the technical solution of the present invention, a tethered airship-type high-altitude wind power generation system with an integrated wing-mounted and floating layout also includes multiple dual-redundant active valves 5, multiple heat pumps, and multiple blowers 6. Heating film strips are laid on the leading edge of the airfoil truss structure 1111, the forward spanwise truss structure 112, and the leading edge of the tail fin 13 to achieve de-icing functionality. The outer skin 141 located at the leading edge of the airfoil truss structure 1111 has multiple openings, and the multiple dual-redundant active valves 5 are respectively installed on multiple... The leading edge of the airfoil truss structure 1111 has multiple openings. In this embodiment, there are five dual-redundant active valves 5, corresponding to five openings. Multiple heat pumps are installed in the middle of multiple vertical constraint trusses 1112 and located inside the outer skin 141. Multiple blowers 6 are fixed on two spanwise truss structures 112 located in the middle and close to the vertical constraint trusses 1112. Each blower 6 penetrates the outer skin 141 and includes four blowers arranged in a matrix. During operation, the blowers have two operating modes (based on the travel position of the controller's solenoid valves): one is to open the outer skin valve and close the internal valve, forming an air intake and exhaust channel between the outer skin 141 and the airfoil; the other is to close the outer skin valve and open the internal valve, forming an airflow channel between the airfoil inside the outer skin 141. When the dual-redundant active valve 5 is opened, the ram air generated by the strong wind in the air can enter the truss space inside the flying wing, forming an air pressure difference. This naturally maintains a certain internal and external pressure on the outer skin 141, ensuring the smoothness (low drag) of the flying wing configuration of the outer skin 141. At the same time, it provides a zero-pressure working environment for the internal buoyancy airbag 12. Combined with the micro-permeability of the outer skin 141, a continuous purging phenomenon is formed on its surface, which can improve the lift-to-drag ratio of the flying wing configuration (flow control technology) and prevent snow accumulation and water dripping on the outer skin. Additionally, if the ambient wind speed is low and the ram air capacity is insufficient, the dual-redundancy active valve 5 can be closed, and the air intake and exhaust channels of the blower outer skin and the flying wing can be opened. The high-flow blower can actively draw in external ambient air to achieve the above functions (redundancy design, safe and reliable). When there are short-term cold clouds / cold currents in the air or when there is a large area of ​​snow or ice accumulation on the outer skin (leading to insufficient system buoyancy or increased weight, and risk of decreased hang time) or when the humidity of the gas inside the flying wing is too high, the heat pump can be turned on, and the air circulation channel inside the blower can be opened to accelerate the internal air heat exchange efficiency, improve the overall temperature level of the gas inside the flying wing, and improve the system buoyancy, the ability of the outer skin 141 to melt ice and snow, and dry the internal gas.

The multiple lightning protection rods 7 are respectively fixed to the top of multiple cross-section airfoil truss structures 1111; the two lightning rods 8 are respectively fixed to the top of two tail fins 13; the lightning protection cables 9 are laid on the multiple lightning protection rods 7 and their two extension ends are respectively connected to the two lightning rods 8, thereby forming a Faraday cage lightning protection barrier. In the event of a lightning strike, the lightning can be attracted and transmitted to the ground for discharge along with the air-to-ground power transmission and tethered cable 2, protecting the airship and the equipment on it.

[0077] To further optimize the technical solution of the present invention, a tethered airship-type high-altitude wind power generation system with an integrated wing-shaped and levitating layout also includes a first equipment compartment 101 and a second equipment compartment 102. A triangular bracket is fixed to the bottom front end of the cross-sectional airfoil truss structure 1111 located in the middle position. The first equipment compartment is mounted on the triangular bracket. The first equipment compartment 101 provides the air pressure, temperature, and installation environment required for the reliable operation of the internal equipment.

The system serves to warn and prevent disruption to civil aviation transport safety, promptly detect and drive away approaching flocks of birds, and protect the aerial ecological environment. The second equipment compartment 102 is installed on top of the cross-section airfoil truss structure 1111 located in the middle and inside the outer skin 114. The second equipment compartment 102 provides the air pressure, temperature, and installation environment required for the reliable operation of the internal equipment. The internal equipment includes at least a combined inertial navigation system, a Beidou positioning and communication terminal, a Tiantong and broadband satellite communication terminal, a barometric altimeter, a differential pressure gauge, and a thermometer. This allows for real-time online monitoring of the position, attitude, air pressure, altitude, differential pressure, temperature, and other information of the aerial wind power generation system. The data is then transmitted to the ground operation and management center via satellite communication telemetry for status monitoring and health management.

[0078] To further optimize the technical solution of the present invention, multiple cameras and vibration measurement devices are installed on the supporting hoisting truss structure 162 to monitor the operating status and vibration of the wind turbine generator 15 in real time, and transmit the data to the ground operation and management center for status monitoring and health management via satellite communication telemetry.
