Description

A system for harvesting electrical energy from wind currents produced at an airportField of the invention

[0001] The invention relates to a system for harvesting electrical energy from wind currents. In particular, the invention relates to a bladeless energy conversion system positioned within a jet blast catchment zone of an aircraft runway for capturing kinetic energy from airflow produced by aircraft engine exhaust during take-off and landing operations and converting it into electrical energy.Background of the invention

[0002] The aviation industry faces increasing pressure to reduce its carbon footprint and transition toward sustainable operations. Airports worldwide are exploring various renewable energy solutions to achieve net-zero emission targets set by international aviation authorities. Traditional approaches have primarily focused on solar installations and conventional wind turbines placed in peripheral areas, but these solutions often face limitations in terms of space requirements, intermittency, and potential interference with aircraft operations.

[0003] Aircraft operations, particularly during take-off and landing phases, generate significant amounts of kinetic energy in the form of jet blast from engine exhaust. This energy is typically dissipated into the atmosphere as turbulent airflow without being harnessed for productive use. An Airbus A320 aircraft, for example, can produce up to 30,000 pounds of force (lbf) of thrust from each engine during take-off, creating powerful airflows that extend hundreds of meters beyond the aircraft.

[0004] Existing approaches to energy generation at airports predominantly rely on conventional renewable sources such as solar panels installed on terminal buildings and parking structures. While effective during daylight hours, these solutions provide no energy generation during nighttime, resulting in inconsistent energy production. Traditional wind turbines with large rotating blades present significant challenges when deployed near airports due to their height, potential radar interference, and wildlife impact. These factors make conventional wind turbines generally incompatible with the strict safety requirements of airport environments.

[0005] The unique environment of airports presents both challenges and opportunities for renewable energy generation. Airports typically feature open, unobstructed areas necessary for aircraft operations, but these same areas are subject to strict height restrictions and safety regulations. The jet blast from aircraft engines represents a consistent and powerful energy source that remains largely untapped in current airport energy systems.

[0006] Several limitations have hindered the development of effective jet blast energy harvesting systems:Height and placement restrictions near runways to maintain clearance for arriving and departing aircraftPotential interference with critical navigation systems, particularly Instrument Landing Systems (ILS)The need for structures that can withstand the powerful and turbulent nature of jet blastRequirements for frangibility in any structures placed within runway safety areasEnsuring that energy harvesting systems do not create electromagnetic interference with airport communications and navigation systems

[0007] Improvements in energy harvesting systems are needed to overcome these challenges, particularly in developing solutions that can effectively capture kinetic energy from jet blast while adhering to the strict safety and operational requirements of airport environments. There is a specific need for systems that can be safely integrated into airport infrastructure, operate reliably in the unique conditions created by aircraft operations, and contribute meaningfully to airports' renewable energy portfolios and sustainability goals.Summary of the invention

The Total Height (TH) is not greater than distance (D)*tan θ, wherein θ is a touchdown angle specific to an airport. Preferably θ is in the range of 1º to 7.5º depending on maximum permissible touchdown angle of the airport at which the at least one bladeless energy conversion unit is installed, wherein most preferably θ is not greater than 3.5º.

The oscillating vertical column turbines are placed behind the Instrument Landing System (ILS) at the airport. The multi-aerofoil oscillating turbines are placed within dips of a terrain within the jet blast catchment zone formed between the aircraft runway and the Instrument Landing System (ILS) or between two neighbouring antennas of the Instrument Landing System (ILS).

[0039] The invention will now be described in detail with reference to preferred embodiments and the accompanying drawings. These embodiments are illustrative only and are not intended to limit the scope of the invention, which is defined by the claims.

[0040] In an embodiment, the present invention relates to a system for harvesting electrical energy from wind currents produced at an airport, particularly from the jet blast generated by aircraft during take-off and landing operations. The invention addresses the growing need for sustainable energy sources at airports by efficiently capturing and converting the kinetic energy from aircraft engine exhaust that would otherwise be wasted. This novel approach not only contributes to renewable energy generation but also leverages existing airport infrastructure and operations, creating a synergistic system that enhances energy efficiency without interfering with critical airport systems or aircraft operations. Now, the invention is described in detailed with reference toto.

[0041] Referring to, an aerial view of an airport (102) is shown, depicting the overall installation context for the system (100) according to the invention. The airport (102) comprises at least one aircraft runway (106) where aircraft take-off and landing operations occur regularly. These operations generate significant jet blast—high-velocity airflow produced by aircraft engines—which contains substantial kinetic energy that traditionally dissipates into the surrounding environment without being harnessed.

[0042] The system (100) for harvesting electrical energy from wind currents is strategically positioned within a defined area referred to as the jet blast catchment zone (A). This catchment zone (A) represents the region where the jet blast from aircraft engines during take-off and landing operations is most concentrated and accessible for energy harvesting. The jet blast catchment zone (A) is delineated based on aircraft movement patterns, prevailing wind directions, and the airport's specific operational characteristics.

[0043] As shown in, the jet blast catchment zone (A) typically extends along one or both sides of the aircraft runway (106), following the trajectory of the exhaust airflow from aircraft engines. The precise boundaries of the jet blast catchment zone (A) zone are determined through comprehensive airflow analysis and consideration of safety parameters to ensure that the energy harvesting system does not interfere with aircraft operations or airport safety protocols.

[0044] Within the jet blast catchment zone (A), the system (100) comprises at least one bladeless energy conversion unit (104) (not explicitly shown inbut positioned within zone A) that is specifically designed to capture the kinetic energy from the airflow produced by aircraft engine exhaust. The at least one bladeless energy conversion unit (104) is positioned at pre-selected locations within the catchment zone to maximize energy capture while maintaining complete compliance with airport safety regulations and operational requirements.

[0045] The system (100) further includes energy conversion means operatively coupled to the at least one bladeless energy conversion unit (104). The energy conversion means efficiently transform the captured kinetic energy from the jet blast into usable electrical energy, which can then be integrated into the airport's power distribution system. This arrangement allows airports to reduce airports reliance on external power sources and decrease overall carbon footprint through the utilization of what was previously untapped energy.

[0046] The strategic positioning of the system (100) within the jet blast catchment zone (A) is critical to its effectiveness. The layout shown inillustrates how the system is integrated into the existing airport infrastructure without requiring significant modifications to the runway (106) or other critical airport facilities. This non-intrusive integration represents a key advantage of the invention, as it allows for energy harvesting without disrupting normal airport operations.

[0047] Now referring toand 2B, the jet blast and jet blast Catchment Zone (A) at which the system installed is illustrated according to the invention. Theand, provides a more detailed representation of the jet blast phenomenon and its relationship to the catchment zone (A) where the system (100) is installed.

[0048] Referring to, a detailed representation of the jet blast (202) produced by an aircraft (128) during take-off operations on the runway (106) is illustrated. Thespecifically demonstrates how the high-velocity airflow emanates from aircraft engines and disperses within the designated jet blast catchment zone (A). As depicted, the jet blast (202) forms a characteristic pattern that extends outward from the aircraft (128), with its intensity gradually diminishing as distance from the aircraft increases.

[0049] The jet blast catchment zone (A) is defined to encompass the area where the kinetic energy of the airflow is sufficiently powerful for effective energy harvesting while remaining at a safe distance from critical flight operations. This zone typically extends alongside the runway (106) where aircraft (128) apply maximum thrust during take-off procedures, generating the most substantial airflow patterns. The careful delineation of this zone enables the positioning of bladeless energy conversion units (104) at optimal locations for maximum energy capture without interfering with aircraft operations.

[0050] The system (100) is specifically designed to harness this otherwise dissipated energy by positioning the at least one bladeless energy conversion unit (104) within the jet blast catchment zone (A). The pattern of the jet blast (202) shown ininforms the strategic placement of these units to intercept the highest velocity airflows, thereby maximizing energy harvesting potential. The distributed nature of the jet blast across the catchment zone allows for multiple energy conversion units to be installed, creating an array that can capture energy from different sections of the airflow pattern.

[0051] illustrates the critical relationship between aircraft (128) approach angles, jet blast (202) patterns, and the design parameters for the at least one bladeless energy conversion unit (104) within the catchment zone (A). Thespecifically highlights the touchdown angle (θ°), which represents the angle at which aircraft approach the runway during landing operations. The touchdown angle (θ°) is a crucial factor in determining the maximum permissible height of the at least one bladeless energy conversion unit (104) to prevent any potential interference with aircraft flight paths.

[0052] In an embodiment, the total height (H) of each bladeless energy conversion unit (104) is selected to optimize airflow capture from the aircraft jet blast (202) while maintaining safe clearance from aircraft operations. Thedemonstrates how this total height (H) is proportional to the distance (D) at which the at least one bladeless energy conversion unit (104) is placed from the runway touchdown zone, following the equation: Total Height (TH) ≤ distance (D) × tan θ. This mathematical relationship ensures that taller at least one bladeless energy conversion unit (104) is positioned farther from the runway, while shorter at least one bladeless energy conversion unit (104) can be safely placed closer to the runway.

[0053] The touchdown angle (θ) is specific to each airport (102) and typically ranges from 1° to 7.5° depending on the maximum permissible touchdown angle established for that particular facility. The touchdown angle (θ) for most airports is in the range of 3° to 3.5° with the majority of airports running at 3°. Preferably, the touchdown angle (θ) is not greater than 3.5° to maintain an additional safety margin. This careful calculation of height in relation to distance creates a graduated arrangement of energy conversion units, with those having lower total height (TH) placed closer to the aircraft runway (106), and those with higher total height (TH) positioned farther away.

[0054] The height distribution, illustrated in, serves two critical purposes: it ensures complete compliance with aviation safety standards by maintaining adequate clearance for aircraft, and it optimizes energy capture by positioning each at least one bladeless energy conversion unit (104) at the ideal height to intercept the jet blast (202) at its particular distance from the runway. This approach maximizes the system's energy harvesting efficiency while prioritizing operational safety.

[0055] FIG.s 3A and 3B illustrate the critical relationship between the at least one bladeless energy conversion unit (104) and the Instrument Landing System (ILS) (130) within the jet blast catchment zone (A).

[0056] Referring to, the strategic positioning of the at least one bladeless energy conversion unit (104) in relation to the Instrument Landing System (ILS) (130) within the jet blast catchment zone (A) is illustrated. Theshows the aircraft runway (106) and the runway touchdown zone (122) where aircraft initially contact the runway during landing. The ILS (130) is a navigation aid that provides precision guidance to aircraft during approach and landing. The ILS (130) is positioned adjacent to the runway in accordance with international aviation standards.

[0057] The arrangement depicted indemonstrates how the at least one bladeless energy conversion unit (104) is positioned within the jet blast catchment zone (A) to ensure the at least one bladeless energy conversion unit (104) do not interfere with the signals transmitted by the ILS (130). The non-interference is crucial as the ILS (130) provides vital vertical and horizontal guidance to approaching aircraft, especially during conditions of reduced visibility. Any disruption to ILS signals could compromise flight safety.

[0058] In an embodiment, the placement strategy for the at least one bladeless energy conversion unit (104) involves consideration of their height and position relative to the ILS (130). The total height (H) of each at least one bladeless energy conversion unit (104) is selected not only to optimize jet blast capture but also to prevent any signal shadowing or reflection that might disrupt ILS (130) functionality. This configuration creates a balanced system that harvests energy efficiently while maintaining the integrity of critical airport navigation systems.

[0059] provides a more detailed view of the specific location (302) behind the Instrument Landing System (ILS) (130) where certain types of the at least one bladeless energy conversion unit (104) can be safely installed. Theillustrates how the runway touchdown zone (122), runway (106), and the at least one energy conversion unit (104) are spatially arranged to maintain the integrity of ILS signals while maximizing energy harvesting potential.

[0060] The location (302) behind the ILS (130) represents a strategic installation point that minimizes potential interference with navigation signals. In one embodiment, the at least one bladeless energy conversion unit (104) is selected from the group of oscillating vertical column turbines, multi-aerofoil oscillating turbines, enclosed blade turbine, and stationary wind energy capture devices. The location (302) is particularly suitable for oscillating vertical column turbines (such as Vortex Bladeless turbines) and stationary wind energy capture devices (such as Aeromine turbines). By positioning the oscillating vertical column turbines and the stationary wind energy capture devices of at least one energy conversion unit (302) behind the ILS, the system ensures that the signal path between the ILS (130) and approaching aircraft remains unobstructed.

[0061] This arrangement takes advantage of the fact that the area behind the ILS typically experiences significant jet blast during take-off operations, particularly when aircraft are accelerating along the runway. The at least one energy conversion unit(102) positioned at location (302) can effectively capture this energy without creating electromagnetic interference or physical obstruction that might affect ILS performance.

[0062] The placement shown inalso considers the operational frequency of the at least one bladeless energy conversion unit (102), particularly those with oscillating elements. The at least one bladeless energy conversion unit (102)operate at frequencies in the range of 0.1-0.6 Hz, a range specifically selected to prevent interference with the ILS (130). This frequency range ensures that any mechanical oscillations or electromagnetic emissions from the energy conversion units do not create harmonics that could disrupt the precision navigation signals required for safe aircraft landing operations.

[0063] Now referring toand, which represents a set of installation points at the jet blast Catchment Zone (A) for installing at least one bladeless energy conversion unit according to the invention.andillustrate the comprehensive installation strategy for the bladeless energy conversion units, focusing on the strategic distribution of installation points (126) within the jet blast catchment zone (A).

[0064] Referring to, a clustered arrangement of installation points (126) within the jet blast catchment zone (A) is illustrated, showing their spatial relationship with the Instrument Landing System (ILS) (130) and its neighbouring antennas (134). Thedemonstrates how the installation points are strategically grouped to form concentrated energy harvesting nodes while maintaining clear paths for communication signals (140) between aircraft and the ILS infrastructure.

[0065] The clustered configuration depicted inrepresents one approach to optimizing the placement of the at least one bladeless energy conversion unit (102) within the airport environment. This arrangement allows for efficient use of available space and facilitates simplified infrastructure connections, including power collection systems and maintenance access. The clusters are positioned to take advantage of areas with particularly strong or consistent jet blast patterns, maximizing energy capture potential at these high-yield locations.

[0066] Critical to this arrangement is the careful positioning of each installation point to prevent obstruction or interference with the communication signals (140) that transmit between approaching aircraft and the ILS (130). These signals provide essential guidance information for safe landings, particularly during adverse weather conditions with reduced visibility. The clustered installation strategy incorporates calculated spacing between groups of installation points, creating corridors through which ILS signals can propagate unimpeded.

[0067] Thealso illustrates how the installation points relate to the neighbouring antennas (134) of the ILS system. These antennas transmit and receive specific radio frequency signals that must remain unobstructed for proper navigational guidance. The clustered installation approach ensures adequate clearance zones around these antennas, preventing signal degradation while still capturing significant energy from jet blast within the catchment zone.

[0068] To further protect signal integrity, the system incorporates specialized equipment including shielded electrical cabling, passive harmonic filters, and active harmonic control equipment. These components work together to prevent electromagnetic interference with the ILS (130) and surrounding instruments. The shielded electrical cabling features a conductive outer layer surrounding internal conductors, effectively containing any electromagnetic emissions that might otherwise affect sensitive aviation electronics. Meanwhile, the passive harmonic filters are configured to attenuate predefined frequencies of electrical noise, and the active harmonic control equipment employs digital signal processors to dynamically mitigate potential interference patterns.

[0069] presents an alternative installation strategy featuring evenly distributed installation points (126) throughout the jet blast catchment zone (A). This uniform distribution creates a more dispersed energy harvesting network compared to the clustered approach shown in, while maintaining the same relationship with the ILS (130), its neighbouring antennas (134), and communication signals (140).

[0070] The evenly distributed configuration offers several distinct advantages for the energy harvesting system. By spacing the installation points at regular intervals throughout the catchment zone, this arrangement ensures more consistent energy capture across the entire area, regardless of variations in jet blast patterns or wind conditions. This approach also creates redundancy in the system, as the performance of the overall network is less affected if individual units require maintenance or experience reduced efficiency.

[0071] A key feature of this evenly distributed arrangement is the balanced impact on ILS signals. Rather than creating concentrated areas of potential interference, the uniform spacing of installation points distributes any minor signal effects evenly throughout the catchment zone. This distribution helps prevent localized signal anomalies and ensures that any minimal effects on communication signals (140) are consistent and predictable, making them easier to account for in system calibration.

[0072] Theillustrates how this even distribution creates multiple pathways for communication signals between aircraft and the ILS infrastructure, ensuring reliable connectivity regardless of aircraft approach path or position. The spacing between installation points is precisely calculated to maintain these signal pathways while maximizing the overall energy harvesting capacity of the system.

[0073] As with the clustered arrangement, this configuration incorporates comprehensive electromagnetic protection measures to safeguard the integrity of aviation systems. The evenly distributed installation points are connected through a network of shielded electrical cabling, and the entire system employs both passive harmonic filters and active harmonic control equipment to ensure that electrical noise and potential interference are eliminated before they can affect the ILS or other sensitive airport electronics.

[0074] and 5B provide detailed illustrations of the installation configurations for multi-aerofoil oscillating turbines (112) at the jet blast Catchment Zone (A) according to the invention. In one embodiment, the at least one bladeless energy conversion unit (102) may be multi-aerofoil oscillating turbines (112).

[0075] Referring to, the strategic installation of multi-aerofoil oscillating turbines (112)is illustrated within natural terrain dips (132) in the jet blast catchment zone (A). Theshows how the at least one bladeless energy conversion unit (104) are positioned between the aircraft runway (106) and the Instrument Landing System (ILS) (130), taking advantage of the natural topography to optimize energy capture while minimizing visual and operational impact.

[0076] The multi-aerofoil oscillating turbines (112) represent one of the primary types of bladeless energy conversion units employed in the system. These turbines feature multiple aerofoil elements that oscillate in response to airflow rather than rotating like conventional wind turbines. This oscillating design is particularly well-suited for capturing energy from the turbulent, high-velocity airflow characteristic of aircraft jet blast, converting this kinetic energy into electrical power through their oscillatory motion.

[0077] The placement within terrain dips (132), as depicted in, serves multiple important functions. Firstly, by positioning these turbines in naturally lower areas of the landscape, their overall height profile is reduced, decreasing potential interference with aircraft operations while still allowing them to capture significant airflow. Secondly, these natural depressions often channel and concentrate airflow, enhancing the energy capture efficiency of the turbines. Thirdly, this placement minimizes visual impact and helps integrate the energy harvesting system seamlessly into the airport landscape.

[0078] The terrain dips (132) shown in theare strategically located within the jet blast catchment zone (A) to intercept the airflow patterns generated during aircraft take-off and landing operations. The multi-aerofoil oscillating turbines (112) installed in these locations incorporate sophisticated internal components that maximize energy conversion efficiency. These include a primary collection chamber incorporating graduated internal guide vanes configured to direct airflow efficiently, secondary acceleration chambers arranged in series with the primary collection chamber for increasing airflow velocity, and pressure differential monitoring systems operatively coupled to these chambers for real-time optimization of airflow dynamics during energy generation.

[0079] This configuration demonstrates the system's adaptive approach to integrating renewable energy technology within the constraints of airport operations. By utilizing natural terrain features and specialized turbine designs, the system harvests substantial energy while maintaining the integrity of critical airport systems and ensuring aircraft safety.

[0080] illustrates an alternative installation strategy for multi-aerofoil oscillating turbines (112), showing their placement between neighbouring antennas (134) of the Instrument Landing System (ILS) within the jet blast catchment zone (A). Thedemonstrates how the at least one bladeless energy conversion unit (104) can be positioned within the ILS infrastructure while avoiding interference with critical navigation signals.

[0081] The ILS antennas (134) shown in theare arranged in a specific pattern to transmit precise guidance signals to approaching aircraft. The spaces between these antennas present unique opportunities for energy harvesting, as they experience significant airflow from jet blast while being situated in areas where properly designed energy conversion units can operate without disrupting signal transmission.

[0082] The multi-aerofoil oscillating turbines (112) are particularly well-suited for this inter-antenna placement due to their compact profile and non-rotating design. Unlike conventional wind turbines with large sweeping blades, these oscillating units create minimal electromagnetic interference and physical obstruction, making them ideal for installation in sensitive areas such as between ILS antennas. Their oscillating elements operate at frequencies specifically selected to prevent interference with the ILS, ensuring that the essential navigation aids remain fully functional.

[0083] The installation configuration shown inillustrates how the multi-aerofoil oscillating turbines are precisely aligned to fit between the antennas (134) while maintaining adequate clearance on all sides. This arrangement allows for effective energy harvesting while preserving unobstructed signal paths for the ILS. The at least one bladeless energy conversion unit (102) are secured to appropriate foundations that comply with airport safety standards, including frangibility requirements where necessary to ensure they would break away safely in the unlikely event of an aircraft excursion from the runway.

[0084] This inter-antenna installation strategy demonstrates the versatility of the multi-aerofoil oscillating turbines and the system's ability to integrate renewable energy harvesting directly into existing airport infrastructure. By utilizing spaces between ILS antennas that would otherwise remain unused, the system maximizes energy generation potential while maintaining complete compatibility with critical airport navigation systems.

[0085] and 6B illustrate the installation configurations for enclosed blade turbines (114) at the jet blast Catchment Zone (A) according to the invention.

[0086] Referring to, the installation of enclosed blade turbines (114)is illustrated within natural terrain dips (132) in the jet blast catchment zone (A). Theshows how the at least one bladeless energy conversion unit (104) are positioned between the aircraft runway (106) and the ILS antennas (134), utilizing the natural topography to enhance energy capture efficiency while maintaining a low profile that minimizes potential interference with airport operations.

[0087] The enclosed blade turbines (114) represent a distinct category of the at least one bladeless energy conversion technology employed in the system. Unlike conventional wind turbines with exposed rotating blades, these units feature internal blade systems completely enclosed within protective housing. This enclosed design offers significant advantages in the airport environment, including enhanced safety, reduced noise, minimal visual impact, and protection from the elements. The enclosure contains and directs airflow over internal blade mechanisms, optimizing energy capture from the turbulent, high-velocity jet blast produced during aircraft operations.

[0088] The placement within terrain dips (132), as shown in, serves multiple important purposes for these enclosed blade turbines. The natural depressions in the landscape help channel and concentrate airflow toward the turbine intakes, enhancing energy capture efficiency. Additionally, by positioning these units in topographical low points, their overall height profile remains below critical sight lines and potential interference zones for aircraft operations and communication systems. This terrain-integrated approach also helps reduce the visual impact of the energy harvesting system within the airport landscape.

[0089] The enclosed blade turbines (114) incorporate several specialized features that enhance their performance in the airport environment. Debris filtration screens installed at air intake points prevent foreign objects from entering the turbine mechanism, maintaining operational efficiency and preventing potential damage. Ice prevention mechanisms enable reliable operation at temperatures below 0°C, particularly important during winter months at many airports. Water drainage channels prevent moisture accumulation within the units, while corrosion-resistant coatings extend their operational life despite exposure to jet fuel residues, exhaust particulates, and varying weather conditions.

[0090] The internal architecture of these enclosed blade turbines includes sophisticated components that maximize energy conversion efficiency. A primary collection chamber incorporating graduated internal guide vanes directs airflow efficiently through the system. This is complemented by secondary acceleration chambers arranged in series with the primary collection chamber, which increase airflow velocity and enhance energy generation. Pressure differential monitoring systems provide real-time optimization of airflow dynamics during operation, adjusting internal components to maximize energy capture across varying wind conditions.

[0091] illustrates an alternative installation configuration for enclosed blade turbines (114), showing their strategic placement between neighbouring antennas (134) of the Instrument Landing System within the jet blast catchment zone (A). Thisdemonstrates how these bladeless energy conversion units (104) can be integrated directly into the ILS infrastructure while maintaining the integrity of critical navigation signals.

[0092] The space between ILS antennas (134) presents a unique opportunity for energy harvesting. These areas experience significant airflow from aircraft operations but require energy conversion equipment that will not interfere with the precise radio frequency signals transmitted by the antennas. The enclosed blade turbines (114) are particularly well-suited for this inter-antenna placement due to their fully contained design. Unlike exposed-blade systems, these enclosed units produce minimal electromagnetic emissions and present a consistent, well-defined physical profile that can be accurately accounted for in ILS signal planning and calibration.

[0093] The installation configuration shown inillustrates how the enclosed blade turbines are positioned to fit between the antennas (134) while maintaining adequate clearance zones that preserve unobstructed signal paths. The fully enclosed nature of these turbines provides inherent shielding that helps prevent radio frequency interference, making them ideal for placement near sensitive communications equipment. Their compact, cylindrical design allows for efficient use of the limited space available between antenna elements.

[0094] The enclosed blade turbines installed in this configuration incorporate all the protective features mentioned previously, including debris filtration screens, ice prevention mechanisms, water drainage channels, and corrosion-resistant coatings. These features are particularly valuable in the inter-antenna environment, where maintenance access may be more limited and operational reliability is especially critical due to proximity to essential navigation equipment.

[0095] This inter-antenna installation strategy demonstrates the system's ability to integrate renewable energy harvesting directly into existing airport infrastructure, utilizing spaces that would otherwise remain unused. By carefully selecting and positioning enclosed blade turbines between ILS antennas, the system achieves significant energy generation while ensuring complete compatibility with the airport's critical navigation and communication systems.

[0096] provides a comprehensive illustration of the installation strategy for oscillating vertical column turbines (110), such as Vortex Bladeless designs, and stationary wind energy capture devices (116) at the jet blast Catchment Zone (A) according to the invention.

[0097] Referring to, the installation of oscillating vertical column turbines (110)and stationary wind energy capture devices (116) is illustrated at a location (302) behind the Instrument Landing System (ILS) (130). Thedemonstrates a comprehensive approach to positioning the at least one bladeless energy conversion unit (102) in areas that experience significant jet blast while maintaining appropriate separation from critical navigation equipment.

[0098] The oscillating vertical column turbines (110) shown in thefeature an innovative design that harnesses energy through controlled oscillation rather than conventional rotation. These slender, vertical structures respond to vortex shedding phenomena when exposed to airflow, creating an oscillatory motion that is converted to electrical energy through internal mechanisms. This design is particularly effective at capturing energy from the turbulent, high-velocity jet blast that propagates behind aircraft during take-off operations.

[0099] Similarly, the stationary wind energy capture devices (116) employ advanced aerodynamic principles to harness energy without rotating components. These units redirect and accelerate airflow through specially designed channels and chambers, creating pressure differentials that drive energy conversion mechanisms. Their stationary nature makes them highly reliable and reduces maintenance requirements compared to systems with numerous moving parts.

[0100] Both technologies are mounted on a specialized support structure (118) that provides stability while complying with stringent airport safety requirements. A critical feature of this support structure is the frangible base section (120), which is engineered to fracture in a controlled manner when subjected to impact forces not exceeding 45 kN. This frangible design ensures that in the unlikely event of an aircraft excursion from the runway, the structure would break away cleanly, minimizing potential damage to the aircraft and enhancing overall safety.

[0101] The support structure (118) is designed to integrate with existing airport blast walls through mounting brackets adapted for secure attachment to blast wall infrastructure. This integration approach maximizes the use of existing airport structures, reducing installation costs and minimizing additional construction requirements. The mounting system is engineered to transfer the forces from high-velocity jet blast safely to the underlying structure while maintaining the frangible characteristics of the base section.

[0102] The oscillating elements of the vertical column turbines operate at carefully selected frequencies in the range of 0.1-0.6 Hz. This frequency range is specifically chosen to ensure that the mechanical oscillations of the turbines do not create harmonics that might interfere with the ILS or other sensitive airport electronic systems. This frequency control is essential for maintaining the integrity of navigation signals while effectively harvesting energy.

[0103] The installation behind the ILS (130), as shown in, provides several operational advantages. This location experiences significant jet blast during aircraft take-off operations when engines are at maximum thrust, creating ideal conditions for energy harvesting. Additionally, by positioning these units behind the ILS rather than between it and the runway, the system eliminates any potential for signal interference in the critical path between the ILS and approaching aircraft.

[0104] The energy harvesting system incorporates comprehensive power management capabilities to ensure the electricity generated is compatible with airport infrastructure. This includes power conditioning equipment that synchronizes electrical output with the airport's power systems, voltage regulation that maintains output within ±5% of nominal value, frequency synchronization between 49.5-50.5 Hz, and harmonic filtering that limits total distortion below 3%. These features ensure that the harvested energy can be seamlessly integrated into the airport's electrical grid without creating power quality issues.

[0105] The installation also includes sophisticated monitoring and safety systems. Structural health monitoring systems continuously assess the integrity and performance of both the turbines and their support structures. Aircraft detection sensors with a minimum range of 500 meters provide advance warning of approaching aircraft, allowing the system to adjust operations if necessary. Weather monitoring equipment measuring wind speeds up to 150 km / h ensures the system operates within safe parameters during varying weather conditions. Automated safety protocols engage at predetermined thresholds to protect both the energy harvesting equipment and airport operations during extreme conditions.

[0106] This configuration demonstrates how the system effectively utilizes multiple bladeless energy conversion technologies in combination, each positioned to take advantage of its unique operational characteristics. By integrating oscillating vertical column turbines and stationary wind energy capture devices at strategic locations behind the ILS, the system achieves significant energy harvesting capability while maintaining complete compatibility with airport safety requirements and operational constraints.

[0107] illustrates a method for optimizing electrical energy harvesting from wind currents produced at an airport, in accordance with an embodiment of the present invention. This method enhances the efficiency of the energy harvesting system by intelligently activating the bladeless energy conversion units (104) based on aircraft operations.

[0108] At Step 802, the processor receives sensor data from a plurality of sensors positioned within the jet blast catchment zone (A) of an aircraft runway (106). These sensors are strategically installed throughout the catchment zone and are configured to capture two primary categories of data, namely the aircraft movement data and wind current data. The aircraft movement data includes parameters such as aircraft position, velocity, engine thrust levels, and estimated time of departure or arrival. The wind current data comprises measurements of wind speed, direction, turbulence patterns, and pressure differentials across the catchment zone. This comprehensive data collection enables the system to develop a detailed understanding of the aerodynamic environment within the airport setting. The sensors may include doppler-based wind sensors, pressure sensors, infrared motion detectors, and connectivity with the airport's air traffic management systems to receive real-time flight information.

[0109] At Step 804, the processor determines an aircraft take-off and landing cycle based on the received aircraft movement data. This step involves sophisticated analysis of aircraft movement patterns to identify recurring operational phases. The processor employs predictive algorithms to recognize the unique signatures of aircraft preparing for take-off (including taxiing patterns, engine spooling activities, and position relative to runway thresholds) and landing operations (comprising approach vectors, descent rates, and deceleration patterns). By identifying these operational phases, the system can anticipate when significant jet blast will occur with high temporal precision. The processor maintains a dynamic database of aircraft types commonly operating at the specific airport, incorporating their unique engine output characteristics and jet blast profiles to further refine prediction accuracy.

[0110] At Step 806, the processor computes a time interval during which maximum wind currents generated by aircraft engine exhaust will impact the at least one bladeless energy conversion unit (104) positioned within the jet blast catchment zone (A). This calculation integrates multiple variables including aircraft type and size, engine specifications, runway position, current meteorological conditions, and the spatial arrangement of energy conversion units within the catchment zone. The processor applies computational fluid dynamics principles to model how the jet blast will propagate through the catchment zone, accounting for terrain variations, existing structures, and prevailing ambient wind conditions. The resulting time interval prediction includes both the estimated start time when significant energy-generating airflow will reach each conversion unit and the expected duration of optimal energy harvesting conditions.

[0111] At Step 808, the processor activates one or more components of the at least one bladeless energy conversion unit (104) prior to the computed time interval to optimize energy capture efficiency. This pre-emptive activation ensures that all mechanical and electrical systems are operational and optimally configured before the high-energy airflow arrives. For oscillating vertical column turbines, this may include adjusting the tension settings and resonance parameters to match the expected frequency of the incoming airflow. For multi-aerofoil oscillating turbines, this involves positioning the aerofoils at the optimal angle to capture the initial airflow surge. Enclosed blade turbines may require adjustment of internal guide vanes and acceleration chamber configurations. Stationary wind energy capture devices need their collection chambers and pressure differential systems prepared for the specific characteristics of the anticipated airflow. This proactive approach eliminates response lag that would otherwise result in lost energy capture opportunity during the initial phases of jet blast.

[0112] At Step 810, the processor adjusts operational parameters of the at least one bladeless energy conversion unit (104) based on real-time wind current data during the computed time interval. This dynamic optimization involves continuous monitoring of actual wind conditions as they develop and making corresponding real-time adjustments to maximize energy conversion efficiency. The system modifies parameters such as oscillation dampening coefficients, internal airflow channelling geometries, pressure release thresholds, and generator load characteristics. For oscillating units, the frequency response characteristics can be fine-tuned to maintain optimal resonance with the actual wind frequency components as they evolve. The system employs closed-loop control algorithms that compare predicted airflow patterns with actual measurements and continuously refine the operational configuration to address any deviations, ensuring peak performance throughout the energy harvesting period regardless of minor variations in aircraft operations or environmental conditions.

[0113] At Step 812, the processor monitors energy output from the at least one bladeless energy conversion unit (104) during the computed time interval. This comprehensive monitoring tracks multiple performance metrics including instantaneous power generation, cumulative energy production, conversion efficiency, mechanical stress levels, and electrical output quality parameters. The system analyses these metrics against expected performance benchmarks developed from historical operation data and theoretical models. This monitoring serves multiple purposes such as it provides real-time verification that the system is functioning correctly, identifies any underperforming components that may require maintenance, validates the accuracy of the predictive models used in earlier steps, and generates operational data that will be incorporated into a continuous learning process to improve future prediction accuracy. Additionally, this monitoring ensures that all electrical parameters remain within specifications to prevent any potential interference with airport communication and navigation systems.

[0114] At Step 814, the system evaluates whether the wind current intensity has decreased below a predetermined threshold. This decision point represents a critical efficiency optimization feature, determining whether energy harvesting operations should continue or be suspended. The threshold is dynamically calculated based on multiple factors including the minimum wind speed required for efficient energy generation by each specific type of conversion unit, the energy consumption of the system itself when active, and the wear characteristics of mechanical components. When wind conditions remain above the threshold, the system continues the optimization cycle, returning to Step 810 to further adjust operational parameters based on the evolving conditions.

[0115] At Step 816, when the wind current intensity has fallen below the predetermined threshold, the processor deactivates the one or more components of the at least one bladeless energy conversion unit (104). This controlled deactivation process follows a specific sequence designed to minimize mechanical stress, prevent electrical transients, and prepare the system for the next energy harvesting opportunity. For oscillating systems, damping mechanisms engage gradually to reduce oscillation amplitude in a controlled manner, preventing abrupt stops that could damage components. Electrical systems transition to standby mode, maintaining minimal power draw while preserving readiness for rapid reactivation. The deactivation process also includes a diagnostic phase that logs performance data from the completed operational cycle, which will be analysed to inform future optimization decisions. The system remains in a monitoring state, with sensors continuing to collect environmental and aircraft movement data in preparation for the next activation cycle.

[0116] The method described inrepresents a sophisticated control system that significantly enhances the efficiency and longevity of the energy harvesting installation. By intelligently activating the bladeless energy conversion units (104) only when significant energy can be captured from aircraft operations, the system maximizes energy production while minimizing unnecessary wear on components. This adaptive approach ensures that the renewable energy generation capabilities of the airport are optimized across varying operational conditions throughout the day.

[0117] Although the invention has been described with reference to one or more preferred embodiments, these embodiments are not limiting. For example, the system for harvesting electrical energy from wind currents produced at an airport could be adapted with different configurations of bladeless energy conversion units, such as arrays or graduated clusters to optimize energy capture from varying jet blast patterns. The support structures need not be uniformly designed across all installation points, rather, they could be customized based on specific locations and local wind conditions to maximize stability and energy harvesting efficiency. The installation points could be segmented within the jet blast catchment zone to create distinct energy harvesting zones, or the system could implement varying densities of conversion units to accommodate different airport layouts and operational patterns. The bladeless energy conversion units could incorporate additional design elements for enhanced durability in extreme weather conditions, or alternative energy storage methods could be integrated to manage energy supply during periods of low aircraft activity. The monitoring systems could include advanced predictive analytics capabilities, or the system could incorporate remote adjustment features for real-time optimization based on changing aircraft operations or weather patterns. The skilled reader will appreciate that many modifications could be made to the embodiments described herein without departing from the scope of the invention, which is defined by the claims.
