Description

field

[0001] This invention relates to modular landing platforms and structural modules for modular landing platforms. background

[0002] Landing platforms are known and can be designed to meet specific needs. Designing a landing platform can be laborious and expensive because it may need to be customized to the application. Once constructed, it can be difficult to adjust or alter the platform. Landing platforms typically cannot be disassembled and reassembled without significant cost. Furthermore, landing platforms usually do not float on water but must be supported on land.

[0003] The object of this invention is to provide an improved landing platform and its components, or at least to provide the public with a useful option. Overview

[0004] According to one example, a structural module for a modular landing platform is provided, the structural module including: a frame having multiple sides, and multiple connecting elements; wherein at least one connecting element can protrude from each side of the frame; each connecting element can include at least one fastening feature; and each connecting element can be configured to connect the structural module to a separate module of the modular landing platform.

[0005] According to another example, a modular landing platform is provided, which may include a first structural module comprising: a first frame having a plurality of sides, and a plurality of first connecting elements; wherein: at least one first connecting element may protrude from each side of the first frame; and each first connecting element may include at least one fastening feature; and a second structural module comprising: a second frame having a plurality of sides, and a plurality of second connecting elements; wherein: at least one second connecting element may protrude from each side of the second frame; and each second connecting element may include at least one fastening feature; wherein the first structural module may be coupled to the second structural module via at least one first connecting element and at least one second connecting element.

[0006] The example can be implemented according to any of the dependent claims.

[0035] Figure 1An example of a structural module 100 for a modular landing platform 900 is shown. The structural module 100 includes a plurality of connecting elements 120 and a frame 110 having a plurality of sides 116. At least one connecting element 120 may protrude from each side 116 of the frame 110 of the structural module 100. Each connecting element 120 may include at least one fastening feature 130 and may be configured to connect the structural module 100 to individual modules of the modular landing platform. In this way, a plurality of structural modules 100 may be coupled together via their respective connecting elements 120 to form at least a portion of the modular landing platform 900.

[0036] exist Figure 1 In the example of structural module 100 depicted, frame 110 is substantially rectangular and includes four beams 112 that define four sides 116 of frame 110. The upper surface of beams 112 has a pattern of two rows of threaded holes 115 configured to receive bolts or screws. Beams 112 can be I-beams or H-beams and can be made of suitable materials, such as steel (e.g., hot-rolled Q345B). Other beam profiles may also be used. In yet another example, individual components constituting frame 110 may not be beams but may be, for example, rectangular tubing. In an example where structural module 100 will be part of a modular landing platform used on the ocean or in water, the beams 112 or other structural components of structural module 100 may be weatherproof. For example, their surfaces may be coated with marine-grade zinc epoxy primer.

[0037] In other examples of structural module 100, frame 110 may have different shapes and / or may include different numbers of sides 116. The shape of frame 110 may be chosen such that multiple structural modules 100 can be assembled together and tesselate to form a modular landing platform with no significant gaps between modules. For this purpose, modular landing platform 900 may include multiple structural modules 100 with frames 110 of different shapes and sizes (e.g., triangular and pentagonal frames 110). In other examples, modular landing platform 900 may include multiple structural modules 100 having substantially identical frames 110.

[0038] Figure 1 The connecting element 120 of the example structural module 100 depicted includes flanges 120, wherein two flanges 120 project from each side 116 of the frame 110. The flanges 120 include fastening features 130 in the form of holes 130, which are configured to receive fasteners such as bolts and nuts. When the structural module 100 contacts an adjacent structural module (e.g., as...), Figure 2As depicted in the illustration, the flanges 120 of each corresponding structural module 100 abut against each other so that the holes 130 are aligned. The aligned holes 130 can then receive fasteners (e.g., bolts and nuts) to connect adjacent structural modules 100 to each other.

[0039] The fastening features 130 and / or connecting elements 120 of the structural module 100 can be configured to allow a small amount of clearance to allow a small amount of relative movement between the connected structural modules 100. This can be advantageous if the modular landing platform is configured for use on a body of water, where a certain amount of deflection or relative movement (e.g., caused by waves) is not uncommon.

[0040] The side 116 of the structural module 100 at least partially defines an interior 140 that can accommodate functional components for the structural module 100 or the modular landing platform 900, as described in further detail below. The frame 110 of the structural module 100 may further include internal structural members (which do not form part of the side 116), such as... Figure 1 The example structural module 100 depicted here has a beam 142. In this example, beam 142 can help improve the stiffness or structural integrity of structural module 100. Beam 142 divides the interior 140 of structural module 100 into two equal sub-interiors 144 and 146. The two sub-interior regions 144 and 146 can accommodate additional components of structural module 100 and / or modular landing platform, as described in more detail below.

[0041] In other examples, the internal structural members of frame 110 (e.g., beam 142) may not be positioned at the midpoint of side 116 of structural module 100, such that sub-internal regions 144 and 146 are not equal. In yet another example, frame 110 may include more than one internal structural member, such that interior 140 defined by side 116 is divided into more than two sub-internal regions. These sub-internal regions may be the same or different in size and shape, depending on the requirements of structural module 100. In yet another example, frame 110 may lack an internal structural member, such that interior 140, at least partially defined by side 116, comprises a single space.

[0042] In other examples of structural module 100, the connecting element 120 and / or fastening feature 130 may differ from... Figure 1 Those depicted herein. For example, connecting element 120 may include a dovetail tenon received by a corresponding slot, or an alignment pin may be used. Other forms of connection are also possible.

[0043] A modular landing platform 900, comprising multiple interconnected structural modules 100, typically uses several different utilities (such as electricity and water) and will accommodate the corresponding utility lines. These utility lines may include, for example, pipes for water supply or drainage, cables or trunking for electricity, and dedicated lines for communications. The exact layout of the utilities and utility lines varies depending on the modular landing platform, for example, on its size and application. Furthermore, if, for example, the modular landing platform 900 expands in size after initial assembly, the exact layout of the utility lines and utility usage points may change throughout the lifespan of the modular landing platform 900.

[0044] For this purpose, one or more of the components (e.g., beams 112) of the frame 110 constituting the structural module 100 may define openings configured to receive at least one utility line. Figure 1 In the example structural module 100 depicted, all four beams 112 of the side 116 of the frame 110 constituting the structural module 100 define orifices 113 configured to receive utility lines. Internal beams 142 also define orifices 113 for receiving utility lines. The orifices may have a typical diameter between 50 mm and 100 mm, but other diameters are possible depending on the size of the utility line to be received.

[0045] The orifices 113 of the side beams 112 and the inner beams 142 are aligned with each other, such that utility lines can be accessed from one side 116 of the frame 110 through the central beam 142 and through the opposite side 116. Therefore, utilities can be delivered through structural modules 100 to any adjacently connected structural modules 100 of the modular landing platform 900, and / or to any components housed within the interior 140 or sub-interiors 144 and 146. In other examples of structural modules 100, only one pair of sides 116 may define orifices 113 for receiving utility lines. In yet another example, if it is not necessary to deliver utilities outside the interior 140 of the structural module 100, only one side 116 may define an orifice 113.

[0046] Orifice 113 may include cable seals or grommets to help protect utility lines and reduce the size of the orifice (if needed). Examples of utility lines that may be received by orifice 113 may include water lines, electrical lines, drainage lines, networking lines, and lines for dedicated communication with sensors. Other types of utility lines are also possible. In some examples, utility lines incorporated into structural module 100 and modular landing platform 900 may include sensors, including pressure sensors, flow sensors, fluid level sensors, current sensors, or voltage sensors.

[0047] The modular landing platform 900 can be assembled by connecting multiple structural modules 100 to each other using connecting elements of each structural module. For example, the modular landing platform 900 may include a first structural module and a second structural module. Each structural module may include multiple connecting elements and a frame having multiple sides, wherein at least one connecting element protrudes from each side of each frame. The first structural module may be connected to the second structural module via at least one connecting element of the first structural module and at least one connecting element of the second structural module.

[0048] Figure 2 A top view depicting a portion of an example of a modular landing platform 900 is provided, comprising four structural modules 100 connected to each other. In this example, each structural module 100 includes a central beam 142 that divides an interior 140 into two separate regions 144 and 146. The connected structural modules 100 define a shared region 148 (defined between each pair of adjacent structural modules 100) and a shared central region 149 (defined between all four adjacent structural modules 100) as each flange 120 protrudes a distance from a corresponding side 116 of the frame 110 of the structural module 100. The shared region 148 and the shared central region 149 can be used to accommodate additional components of the modular landing platform and / or structural modules 100, as described in more detail herein. The size, shape, and number of the shared regions defined by the connected structural modules will depend on the geometry of the frame 110 of the structural module 100 and the number and geometry of the protruding connecting elements 120. More generally, structural modules can be configured such that when a first structural module is coupled to a second structural module, at least one connecting element of the first structural module and at least one connecting element of the second structural module at least partially define an internal area shared between the two structural modules.

[0049] Examples of modular landing platforms 900, comprising multiple interconnected structural modules 100, can be configured for direct use on bodies of water, such as the ocean. In these examples, the modular landing platform must possess sufficient buoyancy to support not only its own weight but also the weight of the helicopter and associated personnel. For this purpose, each structural module 100 of the modular landing platform can be combined with at least one float. Figure 1 In the example depicted, the structural module includes two positioning plates 150 positioned at opposite corners of an interior 140 defined by the side 116 of the frame 110. Each positioning plate 150 defines an aperture 152 configured to receive fasteners. The corresponding float 300 (e.g., Figure 3AThe structure (as depicted) is configured such that when the structural module 100 is stacked with the float 300, the orifice 152 of the positioning plate 150 aligns with the corresponding orifice of the float 300. This simplifies the actions of positioning and securing the structural module 100 to the float 300. For this purpose, the dimensions of the float 300 and the positioning and location of its receiving orifices can be based on the overall dimensions of the frame 110 of the structural module 100 and the positioning plate 150.

[0050] although Figure 1 The example structural module 100 shown includes two positioning plates 150, but in other examples, the total number and positioning of the positioning plates 150 may vary. For example, another structural module 100 with a rectangular frame 110 may include four positioning plates 150 at each corner within the interior 140. In further examples, the positioning plates 150 may not be positioned at the corners, and / or may be positioned outside the interior 140 (e.g., across the connecting element 120 and the side 116).

[0051] Each float 300 can be configured to have a footprint that is the same as or smaller than that of the structural module 100, such that when the floats 300 are stacked with the structural module 100 (e.g., ... Figure 3A As shown, the float 300 does not extend beyond the connecting element 120 protruding from the frame 110 of the structural module 100. This ensures that the floats 300 will be fitted and arranged in the same way as the structural module 100, so that the floats 300 will not obstruct each other when the structural modules 100 are coupled to form the modular landing platform 900. In some examples, the floats 300 may have connecting elements that allow adjacent floats 300 to be coupled together. Figure 3b shows an example of four floats 301 (one of which is labeled) attached to the bottom of the structural module 100. One or more floats may be hollow or include cavities to accommodate equipment, such as charging or air conditioning units or other equipment.

[0052] In other examples, the structural module may alternatively or additionally include other forms of floats. For example, the floats may be built into the frame of the structural module, or may be formed together with the frame of the structural module or formed on the underside of the frame of the structural module.

[0053] In some examples, the float 300 provides sufficient buoyancy to support the weight of the structural module 100. In other examples, the float 300 may be configured to provide sufficient buoyancy to support at least four times the weight of the structural module 100. The applicant has found that the buoyancy level is generally sufficient for the modular landing platform to support the total weight of the multiple structural modules 100, in addition to the weight of the landing helicopter and associated personnel. The exact buoyancy of the float 300 will generally depend on the size of the modular landing platform and the weight of any aircraft used with the modular landing platform.

[0054] When each structural module 100 of the modular landing platform 900 is combined with a float 300, the load supported by each structural module 100 of the modular landing platform 900 can be substantially equal, with the load of the modular landing platform 900 being substantially uniformly distributed across the plurality of structural modules 100. In contrast, other landing platforms (which can be configured to operate on or float on water) may have floats positioned only at the periphery of the landing platform. This geometry makes the landing platform effectively act as a bridging element between the peripheral floats supporting the ends of the landing platform, thereby generating very large bending moments and deflections on the landing platform, with the bending moments and deflections reaching their maximum values ​​at the midpoint (typically where a helicopter lands). If each structural module 100 of the modular landing platform 900 is combined with a float 300, the length of any bridging element between two supports is greatly reduced, thereby minimizing the forces experienced by the modular landing platform / structural module 100.

[0055] In some examples of a modular landing platform 900 comprising multiple interconnected structural modules 100, the configuration or material of the deck tarpaulin or upper surface of the modular landing platform can vary on the modular landing platform. For example, the surface used for the Final Approach and Takeoff (FATO) area must be sufficiently robust to support the weight of the landing helicopter and withstand the mechanical stresses involved in takeoff and landing. In contrast, other portions of the modular landing platform's surface (such as the area surrounding the FATO) may not be used to directly support the helicopter and may face less stringent functional requirements. The specific material or configuration of a given surface for the modular landing platform can depend on the surface's function and its aesthetic requirements, and these materials or configurations can vary on the surface of the modular landing platform. While structural modules 100 can be fabricated with dedicated and predetermined upper surfaces specifically for certain areas of the modular landing platform (e.g., the FATO area), in other examples, structural modules 100 may include configurations for modular deck tarpaulins.

[0056] For this purpose, structural module 100 may include at least one deck support 160. The at least one deck support 160 may be configured to be coupled to at least one modular deck slab 164. Figure 4An example structural module 100 with multiple deck supports 160 is depicted. In this example, the multiple deck supports 160 are secured to beam 112 and central beam 142 using threaded holes 115. The deck supports 160 extend from the side 116 of the structural module 100 toward the central beam 114. In other examples of structural modules 100 lacking the central beam 142 or any internal structural members, the deck supports 160 may span from one side 116 to another. The deck supports 160 may also include ribs 161 to increase the structural integrity of the deck supports 160.

[0057] Each deck support 160 includes a plurality of deck support fasteners 162 configured to engage a modular deck 164 with the deck support 160. The type of deck support fastener 162 may depend on the application of the modular deck 164 and the structural module 100. For example, the deck support fastener 162 may include a dovetail-shaped tail that enters a corresponding recess formed on the underside of the modular deck 164. Alternatively, the deck support fastener 162 may include a tenon that fits into a groove formed on the underside of the modular deck 164. In yet another example, the deck support fastener may include a threaded hole configured to receive a screw or bolt aligned with a corresponding hole formed in the surface of the modular deck 164. This may be particularly useful when the modular deck 164 is made of metal (e.g., steel). In other examples, the modular deck 164 may be made of other materials (e.g., wood), depending on the application of the modular deck.

[0058] In other examples, the modular deck 164 can be directly connected to the structural module 100 without the need for additional deck supports 162. Figure 5 An example structural module 100 is shown, featuring a modular deck 164 in the form of FATO plates 1641. In this example, the FATO plates 1641 are directly connected to beams 112 of the frame 110 of the structural module 100 via holes 115 and appropriate fasteners. Two FATO plates 1641 extend from the sides of the structural module 100 to the central beam 142 (in... Figure 5 (Not visible in the image). In this example, the outward-facing holes 1151 on the upper surface of beam 112 freely receive deck supports 160 or additional FATO plates from adjacent structural modules 100, as indicated by FATO plates 1642 and 1643.

[0059] In addition to modular deck paving across any internal structural components of frame 110 and structural module 100, structural module 100 and modular landing platform 900 may include modular deck paving across two or more connected structural modules 100. For example... Figure 2The example portion of the modular landing platform 900 depicted shows four structural modules 100 connected together, thus defining a shared area 148 and a shared central area 149. Modular deck paving can be connected to the frames 110 and / or connecting elements 120 of two adjacent structural modules 100 (or their corresponding deck supports) to span the shared area 148. Modular deck paving can span the shared central area 149, and this modular deck paving is connected to the frames 110, connecting elements 120, or deck supports of all four structural modules 100.

[0060] In some examples, functional components can be integrated into modular deck panels. Figure 6A An example of a FATO board 1645 is depicted, which is configured to span an area between two or more connected structural members 100. In this particular example, the FATO board 1645 includes a lamp 1000, and the FATO board 1645 is configured to cover a shared central area 149 formed by four connected structural modules 100, as shown. Figure 2 As shown (i.e., equivalent to) Figure 5 (FATO board 1643 in the document). The lamp 1000 can be connected to electrical and / or necessary communication lines via, for example, utility lines (which pass through openings 113 defined by the frame 110 of the structural module 100). Figure 6B In another example shown, the FATO panel 1647 includes nozzles 1010 for fire suppression. In other examples, additional functional components may be integrated into the modular deck slab.

[0061] In some examples, the modular deck 164 may incorporate one or more sensors. For instance, the modular deck 164 may incorporate motion sensors, cameras, weather sensors or weather stations, LiDAR sensors, humidity sensors, and lux sensors. These sensors may be connected to relevant utility lines (such as power lines and communication lines) housed within the structural module 100.

[0062] Functional components can be integrated not only into the modular deck paving used with the structural module 100 / modular landing platform 900, but also into the structural module 100 itself or shared among multiple structural modules 100. Figure 7A A portion of a modular landing platform 900 and an example of a structural module 100 including a drainage module 200 are depicted. The drainage module 200 is located between a shared area 148 defined by a pair of coupled structural modules 100. In this example, the drainage module 200 includes a grille 210 and a drainage tray 220 defining a drainage inlet 225. Figure 7B(As shown). The drain tray 220 includes a flange 224 extending around its periphery and configured to span adjacent connected structural modules 100. In this example, the flange 224 is provided with a hole pattern that aligns with holes defined on the upper surfaces of the beams 112 and connecting elements 120 of the structural modules 100, such that the flange 224 can be fastened to each respective structural module 100 via, for example, bolts. In other examples, the drain tray 220 can be secured to any one or both structural modules 100 using alternative means such as clips or clamps. The grille 210 defines similar holes around its periphery, allowing it to be secured to the drain tray 220 and the structural modules 100.

[0063] In other examples, the grille 210 and the drain tray 220 can be integrated to form a single component. In yet another example, if the drain module 200 is small enough, the grille 210 can be omitted from the drain module 200. Furthermore, although... Figure 7A The example drainage module 200 depicted occupies a shared area 148, but in other examples, the drainage module 200 may be located elsewhere on the modular landing platform 900 and / or structural module 100. For example, the grille 210 and drainage tray 220 may span the entire frame 110 of a single structural module 100 without being coupled to additional structural modules 100. In yet another example, the drainage module 200 may be configured to occupy a shared central area 149 defined between four adjacent, coupled structural modules 100.

[0064] Figure 8 An example of a portion of a modular landing platform 900 is depicted, which includes a drainage system 250 and a plurality of connected structural modules 100. The drainage system 250 includes a plurality of drainage inlets 225, which in this example are provided by a drainage module 200. The drainage inlets 225 are configured to discharge liquids from the surface of the modular landing platform. For example, each drainage inlet can discharge rainwater, seawater, spilled fuel, or water used during firefighting from the surface of the landing platform. The drainage system 250 further includes a drainage reservoir 260. The drainage reservoir 260 is in fluid communication with the plurality of drainage inlets 225 via utility lines, which may, for example, be received in orifices 113 defined by frames 110 of at least some of the connected structural modules 100. In some examples, the drainage reservoir 260 may be a box (e.g., a flexible water tank) stored within the interior of the structural module 100. For example, the drainage reservoir 260 may be stored in one of the interior areas (144 or 146) of the structural module 100.

[0065] The drain reservoir 260 can be used to temporarily store runoff or fluid discharged through the plurality of drain inlets 225. The drainage system further includes a drain outlet 270 in fluid communication with the drain reservoir 260. The drain outlet 270 can be configured between a closed state (to collect runoff in the drain reservoir 260) and an open state (to allow the drain reservoir 260 to be emptied). The drain outlet 270 can be configured such that it is open when the modular landing platform 900 operates in its default state. This means that runoff collected via the drain inlets 225 will by default exit the drain outlet 270 unless the drain outlet 270 is intentionally closed. Closure of the drain outlet may occur when an adverse or abnormal condition is detected on the landing platform to prevent contaminants from entering the environment. For example, the drain outlet 270 may be closed when a temperature sensor on the modular landing platform 900 detects a fire, or when a fuel spill sensor detects a fuel spill during refueling of a docked helicopter. Drainage outlet 270 can also be closed for scheduled routine testing of the fire suppression system within the modular landing platform 900.

[0066] In yet another example, drainage system 250 may include multiple drainage reservoirs 260. These multiple drainage reservoirs 260 may share a common drainage conduit, ensuring fluid communication between them. This can help increase the total capacity of drainage system 250 and help ensure that the weight distribution of water collected via drainage inlet 225 is distributed across the modular landing platform 900.

[0067] Additional examples of modular landing platforms, which may be attached to or replace the drainage module 200, may also incorporate one or more fire suppression modules. Figure 9 An example of a fire suppression module 400 is depicted. The fire suppression module 400 includes a water reservoir 410 in fluid communication with a water pump 420. The water pump 420 is in fluid communication with a nozzle 430. The fire suppression module 400 may further include an aqueous film-forming foam (AFFF) pump 440 in fluid communication with an AFFF reservoir 445 and with the nozzle 430. The AFFF pump 440 may be configured to mix foam and water at a substantially 3% ratio. In some examples, the fire suppression module 400 may include multiple nozzles. Components of the fire suppression module 400 (e.g., water pump 420, AFFF pump 440, and AFFF reservoir 445) may be located on a skid 450 for integration into a modular landing platform 900.

[0068] Figure 10An example of a portion of a modular landing platform 900 incorporating a fire suppression module 400 is depicted. In this example, the fire suppression module includes two water reservoirs 410 and 412, which are located within internal regions 144 and 146 of the structural modules 100 of the modular landing platform 900. A skid 450 of the fire suppression module 400 is located in a shared region 148 defined between two adjacent structural modules 100, while a nozzle 430 is located within a shared region 149.

[0069] In some examples, the modular landing platform 900 may further include at least a second fire suppression module 400. The second fire suppression module may also include at least one second water reservoir in fluid communication with a second water pump. The second water pump may be in fluid communication with a second nozzle, such that the first fire suppression module 400 is independent of the second fire suppression module 400. The second fire suppression module may further include a dedicated AFFF pump and AFFF reservoir that are not in fluid communication with any component of the first fire suppression module 400.

[0070] Integrating two or more independent fire suppression modules 400 into a modular landing platform 900 increases redundancy in critical safety systems and simplifies engineering. The total number of nozzles 430 required for fire suppression in the landing platform can vary depending on the size and shape of the modular landing platform, and in a centralized supply system, the corresponding piping and support infrastructure can be custom-designed (e.g., considering the number of pipes, bends in the pipes, etc.) to ensure sufficient flow at the nozzles. In contrast, separating each nozzle, reservoir, and associated pump into a separate and independent fire suppression module means that the entire fire suppression system can be scaled up or down for a given modular landing platform by incorporating fewer or more individual fire suppression modules. Individual fire suppression modules can also be placed where needed or moved after installation to accommodate changes in the overall size of the modular landing platform 900.

[0071] In some examples, the water reservoir 410 may be housed within the interior 140 of the structural module 100 of the modular landing platform 900. For example, the water reservoir 410 may be a flexible water tank or flexible water bag stored in the interior regions 144 or 146 of the structural module 100. In some examples, the first fire suppression module 400 may include a second water reservoir 412. The first water reservoir 410 and the second water reservoir 412 may be stored in the interior regions 144 and 146, respectively. Similarly, in some examples, the pump 420 may be stored in a shared region 148 defined by two connected structural modules 100. In yet another example, the nozzle 430 may be located on a surface of the landing platform that covers a shared central region 149 defined by four adjacent connected structural modules. For example, the nozzle 430 may be integrated into a FATO plate covering the shared central region 149, such as... Figure 6B As shown. Multiple fire suppression modules 400 and associated nozzles 430 may be located in and around the FATO area to ensure adequate coverage of the FATO area by the sprayers. The number and layout of the fire suppression modules 400 and nozzles 430 may depend on the size and shape of the modular landing platform 900, as well as the size and shape of the individual structural modules 100 included in the modular landing platform 900.

[0072] In examples of modular landing platforms that include one or more fire suppression modules 400 and one or more drainage modules 200 (and / or drainage systems 250), components of the fire suppression module 400 may be fluidly connected to the drainage module 200 or drainage system 250. For example, one or more reservoirs 410 may be fluidly connected to a drainage reservoir 260, a drainage outlet 270, or a drainage inlet 225. This means that water or other fluids used during firefighting can be captured by the drainage infrastructure and reintroduced into the reservoirs of the fire suppression system, which can simplify the periodic testing of the fire suppression system. In some examples, one or more filters or filtration stages may be present between the drainage inlet (e.g., inlet 225) and the reservoir 410.

[0073] Another example of a modular landing platform may include, or alternatively include, one or more power modules, which may be integrated into a single structural module 100 or shared among multiple structural modules 100. For example, a single power module may include one or more batteries, one or more charge controllers, and one or more inverters. The power modules may be designed to collectively power the entire modular landing platform, including, for example, the platform's lights, electronic systems, sensors, pumps, and fire suppression modules. In this way, the modular landing platform may not require any electrical connection to an external power source.

[0074] Each power module can be configured such that the entire power module is assembled within the internal region 144 or 146 of the structural module 100, thereby allowing the number of power modules to be easily scaled in a modular manner proportional to the total number of structural modules 100 of the modular landing platform 900. The total capacity of each power module can be configured, for example, to support four fire suppression modules 400, while its dimensions are also determined to be assembled within the internal region 144 or 146. The power modules can also be linked together to ensure power redundancy of the modular landing platform 900. For example, a modular landing platform requiring three power modules to operate reliably can include a total of four power modules, such that the modular landing platform can still operate without interruption if any single power module suffers an electrical failure or unintentional battery depletion. Other examples of the modular landing platform 900 may include different numbers of power modules or different levels of redundancy.

[0075] The modular landing platform 900 may further include one or more solar panels for supplying power to the batteries of the power modules. In some examples, these solar panels may form one or more portions of the modular deck 164 on the modular landing platform 900. These solar panels may also be placed between adjacent structural modules 100, such as in a shared area 148 defined by two adjacent structural modules 100. In other examples, one or more edge modules may be used to position the solar panels at the outermost edge of the modular landing platform (e.g., space 848), as described below. The number and size of the solar panels may depend on the overall requirements of the modular landing platform and the total number of power modules. In some examples, the modular landing platform may be configured to include a sufficient number of solar panels to keep the power modules fully charged so that connection to an external power source is not required.

[0076] In some examples of the modular landing platform 900, some of the connecting elements 120 protruding from the side 116 of the outermost structural module 100 at the edge of the modular landing platform 900 are not connected to other structural modules 100, but remain "dangling". In some examples, these "dangling" connecting elements can be used to anchor the structural module 100 or the modular landing platform 900 to another structure.

[0077] For example, in an example where the modular landing platform 900 is floating on water, the suspended connection element 120 can be connected to a bridging member or ramp, allowing pedestrian access to the modular landing platform 900. In another example, the suspended connection element 120 can be additionally or alternatively connected to a structure that anchors the floating modular landing platform 900 in a specific location. In yet another example, the suspended connection element 120 can be configured as a towing point for the modular landing platform 900, allowing it to be towed or manipulated on the water surface.

[0078] Figure 12 An example of a ramp module 600 is depicted, configured to connect with the outermost structural module 100 of a modular landing platform 900. In this example, the ramp module 600 includes two connecting elements 620 configured to connect with two connecting elements 120 projecting from a single side of the structural module 100. The ramp module 600 is particularly suitable for use with examples of the modular landing platform 900 configured for use on land, especially when the modular landing platform 900 is not buried in the ground. For example, the ramp module 600 can be used to drive equipment or wheeled vehicles onto or off the modular landing platform 900 and can be used to improve the accessibility of the modular landing platform (e.g., to facilitate wheelchair users). Figure 12 In the example ramp module 600 depicted, the ramp module 600 is the same width as the individual structural module 100 of the modular landing platform. Multiple adjacent ramp modules 600 can be coupled to adjacent connected structural modules 100 to determine the width of the extended ramp.

[0079] The ramp module 600 can also be configured to receive modular deck slabs, similar to the modular deck slab 164 of the structural module 100. For example, beams 660 that help provide structural integrity to the ramp module 600 can also serve as deck supports, allowing the modular deck slabs to be coupled to the ramp module 600. In some examples, the modular deck slabs can be simple deck slab materials, such as wooden deck slabs or metal sheets. In other examples, the modular deck slabs may include functional components, such as lights and sensors.

[0080] In other examples of the ramp module 600, the ramp module 600 may include a different number of connecting elements 620. The number and arrangement of the connecting elements 620 may be determined at least in part by the number and arrangement of the corresponding connecting elements 120 of the structural module 100. Furthermore, although Figure 12The ramp module 600 shown is configured to connect to a single side of a single structural module 100, but this can differ in other examples of the ramp module 600. For example, the ramp module 600 may have a width greater than that of a single structural module 100 and may be configured to connect to multiple structural modules 100 via their respective connecting elements 120. Furthermore, although... Figure 12 The ramp module 600 depicted is configured to connect to only a single side of the structural module 100, but other examples of the ramp module 600 can be configured to connect to multiple sides of the structural module 100. For example, the ramp module 600 can connect to two sides of the structural module 100 around a corner, making the ramp module 600 substantially L-shaped.

[0081] Figure 13A An example of a staircase module 700 is depicted, configured to connect with the outermost structural module 100 of a modular landing platform 900. The staircase module 700 is particularly suitable for use with examples of the modular landing platform 900 configured for use on land, especially when the modular landing platform 900 is not buried in the ground, and can be used to allow personnel access to the modular landing platform 900. The staircase module 700 includes a plurality of connecting elements 720 configured to connect with connecting elements 120 of the structural module 100. In this particular example, the staircase module 700 includes five connecting elements 720. Four of these connecting elements 720 connect with connecting elements 120 of a single structural module, while one connecting element (720') connects with connecting elements 120 of an adjacent connected structural module 100.

[0082] The stair module 700 may further include a plurality of deck supports 760 configured to be coupled to at least one modular deck slab 764. Figure 13B An example staircase module 700 is depicted, in which a modular deck slab 764 is connected to a deck support 760. In this example, the modular deck slab 764 is a wooden deck slab, but other examples may use a metal deck slab and / or functional components integrated into the modular deck slab 764, such as lights and sensors.

[0083] In other examples of the stair module 700, the stair module 700 may include more or fewer connecting elements 720. This may depend on the desired shape of the stair module 700 and the corresponding shape of the structural module 100 constituting the modular landing platform 900. For example, in some examples, the stair module 700 may be as wide as a single side of the structural module 100, equivalent to... Figure 12The ramp module 600 depicted in the diagram allows adjacent stair modules 700 to be connected to adjacent structural modules 100 to create staircases of different widths.

[0084] Figure 14 Examples of different edge modules connected to the outermost structural module 100 of the modular landing platform 900 are depicted. In this example, each edge module is connected to the structural module 100 to define space therebetween. Figure 14 Three separate edge modules are depicted. The first edge module 810 includes a beam 812 and two arms 814 projecting from the beam 812, such that the edge module 810 has a substantially right-angled U-shape. In this example, the beam 812 is substantially longer than each arm 814. Each arm 814 is configured to connect with a connecting element 120 of the structural module 100. Due to the overall shape of the edge module 810, the two arms 814 connect with a pair of connecting elements 120 projecting from a single side of the frame 110 of the structural module 100. In this example, each edge module 810 is configured such that when the edge module 810 is connected to its corresponding structural module 100, the edge module 810 and the structural module 100 define a space 848 between the edge module 810 and the side from which the connecting element 120 projects. In this example, the space 848 has the same shape and layout as the shared space 148 defined between each pair of adjacent connected structural modules 100 (e.g., ...). Figure 2 (As shown).

[0085] Similarly, edge module 820 also includes beam 822 and two arms 824 projecting from beam 822, such that edge module 820 also has a substantially right-angled U-shape. In this example, beam 822 has the same length as each arm 824, and each arm 824 is configured to connect with the connecting element 120 of the individual structural module 100. In other words, edge module 820 is configured to connect with a pair of adjacent structural modules 100 due to the shape of edge module 820 and the shape of structural module 100. When edge module 820 is connected with a pair of adjacent structural modules 100, edge module 820 and the pair of adjacent structural modules 100 define a space 849. In this example, space 849 has the same shape and layout as the shared space 149 defined between four adjacent structural modules 100 (e.g., ...). Figure 2 (As shown).

[0086] Finally, edge module 830 includes a right angle 832 from which two arms 834 project perpendicularly. The arms 834 project toward each other but do not meet, such that edge module 830 is substantially in the shape of an open quadrilateral. Each arm 834 is configured to engage with a connecting element 120 of structural module 100. The two connecting elements 120 engaged with edge module 830 belong to the same structural module 100 but project from different sides of structural module 100. When edge module 830 is engaged with structural module 100, edge module 830 and structural module 100 define a space 849'. In this example, space 849' has the same shape and layout as the shared space 149 defined between four adjacent engaged structural modules 100 (e.g., ...). Figure 2 (As shown).

[0087] Edge modules 810, 820, or 830 can be used to define additional spaces (e.g., 848, 849, 849') for accommodating different components or modules of the modular landing platform 900, such as fire suppression module 400, drainage module 200, or elements of the FATO area. These modules or elements can be positioned at the outermost edge of the modular landing platform 900 by means of the edge modules. For example, additional space 848 can be used to accommodate solar panels positioned at the outermost edge of the modular landing platform 900 to power one or more electrical modules as described above.

[0088] Of course, it should be noted that Figure 14 The shapes and sizes of the edge modules 810, 820, and 830 shown are merely examples. In other examples, the edge modules may have different shapes, sizes, and layouts. The shape, size, and layout of the edge modules may depend on the shape of the structural module 100 and the overall arrangement of its connecting elements 120. Furthermore, since the shapes and sizes of the edge modules and structural modules determine the overall size and shape of the space defined therebetween, the shape and size of the edge modules or structural module 100 may be determined at least in part by the requirements of the space defined therebetween. In yet another example, the connecting elements 120 of the outermost structural module 100 of the modular landing platform 900 may be used to support guardrails or other functional modules. Figure 11AAn example of a portion of a modular landing platform 900 is depicted, which includes multiple connected structural modules 100 and guardrails 510. Guardrails 510 may be connected to the outermost structural module 100 of the modular landing platform 900 via overhanging coupling elements 120. In some examples, guardrail modules 500 may include guardrails 510 and may be connected to structural module 100 via one or more coupling elements 120. Guardrail modules 500 may further include guardrail actuators 520 configured to raise or lower guardrails 510. If the modular landing platform 900 includes multiple guardrail modules 500, the guardrails 510 of each guardrail module 500 may be raised or lowered independently of the guardrails 510 of other guardrail modules 500. The guardrail actuators 520 may be powered via utility lines housed within the structural module 100.

[0089] Figure 11A An example guardrail module 500 is depicted, including guardrail 510 and guardrail actuator 520. The guardrail module 500 further includes a flange 530 (in... Figure 11B (described more clearly in the image), the flange is provided with a hole pattern 535, which is configured to engage with the fastening feature 130 of the connecting element 120 of the structural module 100 (i.e., Figure 1 The hole 130 in the example structural module 100 depicted is aligned. The flange 530 includes a pivot 537 about which the guardrail 510 rotates via a guardrail actuator 520, thereby allowing the guardrail 510 to be raised or lowered. In other examples, the guardrail 510 may not be a separate module and may be integrated with the structural module 100.

[0090] Figures 15 to 18 A structural module 900 is depicted, which includes a pre-conditioned air (PCA) unit 901 mounted to a frame 902. Depending on the climatic conditions in which the landing platform is operating, the interior of the aircraft may require heating or cooling while it is on the landing platform to provide passengers with the desired temperature conditions upon entry. Standard marine integrated condenser and evaporator / blower units (such as Gree commercial air conditioners from the CYR series) may be suitable for this application. Suitable units may include heat exchangers. Such units may be capable of heating or cooling the air supplied to the aircraft. In the case where the landing platform is deployed on water, one or more heat exchange coils of the heat exchanger may be submerged in water to use water as a heat source. In the case where the landing platform is deployed on land, one or more heat exchange coils of the heat exchanger may be buried in the ground supporting the structural module to utilize ground heat sources.

[0091] The PCA unit draws air from the environment, rather than recirculating the air from the aircraft, because there is no return duct. The PCA unit is designed to cool / heat ambient air by up to approximately 15°C to 20°C. This may be sufficient when the temperature difference is not too large. In some regions, temperatures can reach 40°C to 50°C in summer, and therefore, in the worst-case scenario, a single PCA unit may only be able to reduce the temperature to 30°C to 35°C, which is insufficient. In such cases, a dual PCA unit can be used. The first PCA (identical to PCA 901), located below deck 907, provides first-stage cooling by supplying cooled air to the environment surrounding PCA 901 below deck 904, thus pre-cooling the air drawn in by PCA 901. Thus, we have investigated a tandem system with two independent AC units. By operating in tandem, the 40°C to 50°C air supplied to the first PCA can be cooled to 10°C to 15°C, which is the desired inlet temperature for rapidly cooling the cabin and other systems within the aircraft.

[0092] A hatch 903 may be located in deck 904, and this hatch can be opened to allow access to the air supply hose. The hatch may be a waterproof sliding or pivoting hatch, which remains fixed to the deck when opened or closed. The hose may consist of an external protective sleeve 906 (such as a large-diameter ridged drain pipe) and a collapsible hose 905 that transmits air from the PCA. The length of the hose may be limited to ensure that the hose does not engage with the aircraft propeller blades. Different adapters may be provided to connect hose 905 to the aircraft. The hose may include a retraction mechanism. A switch may be located in deck 904 to activate the PCA, or activation may be performed remotely or via remote control.

[0093] refer to Figure 19 and Figure 20 It can also provide a battery charging system. The main power supply system can be located off-deck (although in some cases it can also be on-deck), with power supply cables extending below deck to structural module 910. Hatch 911 can be opened (see...). Figure 20 The hatch (raised and supported by gas impact) allows charging cable 912 to extend from it, enabling plug 913 to be inserted into the aircraft to provide power. For safety, cable 912 can be (or may have a short length of) approximately 2 to 4 meters. Cable 912 can be retractable, allowing it to coil back within structural module 910. As a suitable system is developed to provide the required power, a wireless power transmitter can be integrated into or above the structural module. The wireless power transmitter may be able to be raised and lowered relative to the deck for tight coupling with the aircraft's wireless power receiver.

[0094] In summary, a modular landing platform comprising multiple interconnected structural modules has been disclosed, along with structural modules for the modular landing platform. The modular landing platform and structural modules disclosed herein allow for flexible design and assembly of the modular landing platform to accommodate diverse and unique sets of requirements. The size, layout, and other characteristics of the modular landing platform can be configured according to its needs. Furthermore, if the requirements of the modular landing platform change, its size, layout, or configuration can be adjusted over time. For example, the modular landing platform can be expanded or reduced in size by simply adding or removing structural modules. If necessary, the entire modular landing platform can also be disassembled and reassembled at different locations.

[0095] Integrating modular drainage and fire suppression infrastructure into modular landing platforms simplifies the design of critical infrastructure for a given landing platform, as the design does not need to be customized for a single landing platform. This also simplifies modifications to modular landing platforms, as the requirements for redesigning the supply and drainage systems are minimal or nonexistent. The use of modular deck paving also means that certain parts of the modular landing platform (such as the FATO area) can be adjusted or modified as needed, simplifying the design and construction of the FATO area. Other modular deck paving components can also be adapted to meet the needs of the modular landing platform user. The size, shape, and other characteristics of the modular landing platform can also be adjusted to ensure it always complies with evolving laws and regulations.

[0096] Integrating floating bodies into the structural modules of a modular landing platform allows for the assembly of such platforms that float on water. This significantly expands the available area for assembling landing platforms and allows for their construction or assembly in remote locations or where conventional landing platforms are not feasible. It also reduces the costs associated with designing and manufacturing landing platforms.

[0097] Connecting elements extending from the outermost structural module at the edge of the modular landing platform can be further used for anchoring, support, or other functional purposes, including for connecting modular guardrails. In other examples, specific structural modules can be designed for edges of the landing platform lacking “overhanging” connecting elements.

[0098] In this specification, the term "landing platform" is used broadly to refer to a modular landing platform designed for vertical takeoff and landing (VTOL) vehicles and short takeoff and landing (STOL) vehicles. As used herein, the term "landing platform" encompasses, but is not limited to, helipads, helicopter decks, helicopter landing sites, vertical landing sites, vertical takeoff and landing pads, vertical takeoff and landing decks, and vertical takeoff and landing airports. The term includes landing platforms suitable for use with a wide variety of air vehicles, such as helicopters, unmanned aerial vehicles, tiltrotor aircraft, thrust vectoring aircraft, and other aircraft capable of vertical or short takeoff and landing. The term also encompasses future landing platforms suitable for emerging and future VTOL and STOL technologies.

[0099] Similarly, although the term "helicopter" is used in this specification, it should be understood that the modular landing platform disclosed herein is also suitable for use with other types of VTOL and STOL vehicles, including unmanned aerial vehicles, tiltrotor aircraft, and thrust vectoring aircraft. While the invention has been illustrated by describing several embodiments, and while these embodiments have been described in detail, the applicant is not intended to limit the scope of the appended claims to or in any way restrict it to such details. Further advantages and modifications will be apparent to those skilled in the art. Therefore, the invention is not limited in its broader aspects to the specific details, representative devices and methods, and illustrative examples shown and described. Accordingly, variations on such details may be made without departing from the spirit and scope of the applicant's overall inventive concept.
