Description

Technical Field

[0001] This application pertains to the field of air transport, and in particular relates to an aircraft take-off and landing platform. Background Technology

[0002] The background description provided herein serves to give a general overview of the background of this application. The work of the currently identified inventors to the extent described in this background section, and aspects of this description that do not constitute prior art at the time of application, are neither expressly nor impliedly acknowledged as prior art in conflict with this application.

[0003] With the comprehensive development of the low-altitude economy, vertical takeoff and landing (VTOL) aircraft, as one of its core technological pathways, are receiving increasing attention. The core mechanism for achieving VTOL lies in the use of a multi-rotor system. Its working principle is based on the high-speed rotation of multiple rotors, causing rapid and non-uniform dynamic changes in the air beneath the fuselage, thereby providing lift for the aircraft and enabling smooth takeoff or landing. However, during this process, as the aircraft approaches the ground, the airflow beneath it is obstructed by the ground, triggering a ground effect. This ground effect interferes with the stability of the airflow beneath the aircraft, threatening the smoothness and safety of the takeoff and landing process.

[0004] Chinese patent publication CN117622569A discloses a drone take-off and landing platform, comprising: a first platform frame and a second platform frame stacked and spaced apart; a first support fabric detachably mounted on the side of the first platform frame facing away from the second platform frame to form a first plane, the first support fabric having a plurality of air holes; a second support fabric detachably mounted on the side of the second platform frame facing the first platform frame to form a second plane; the orthographic projection of the second support fabric along a first direction at least completely covers the first support fabric; the first direction is the direction in which the first platform frame and the second platform frame are stacked; and a support assembly detachably mounted on the side of the second platform frame facing away from the first platform frame, used to support the support surface of the drone take-off and landing platform. The first support fabric can, while providing stable support for the drone, transmit airflow downwards through the air holes and discharge it through the gap between the first and second support fabrics to prevent ground effect. However, this structure is relatively complex, and the efficiency of airflow discharge is not high enough. Therefore, a new aircraft take-off and landing platform is needed. Summary of the Invention

[0024] The following description is exemplary in nature and is not intended to limit this application, application, or use. Furthermore, it is not intended to be limited by any express or implied theory presented in the foregoing technical field, background art, summary of the invention, or the following detailed description. It should be understood that throughout the drawings, corresponding reference numerals identify similar or corresponding parts or features.

[0025] This application will now be further elaborated. In the following paragraphs, different aspects of this application are defined in more detail. Unless expressly indicated to the contrary, each aspect so defined may be combined with any other aspect(s). In particular, any feature indicated as preferred or advantageous may be combined with any other feature(s) indicated as preferred or advantageous.

[0026] To address the problems existing in the prior art, this application provides a new aircraft takeoff and landing platform that can effectively prevent ground effect. (See attached document.) Figure 1 This illustration shows an aircraft takeoff and landing platform 100 according to the principles of this application. The aircraft takeoff and landing platform 100 includes a carrying platform 110 and a support structure 120, wherein the carrying platform 110 is used to carry an aircraft for takeoff or landing. The support structure 120 is connected to the ground-facing side of the carrying platform 110 to support the carrying platform 110, thereby raising the carrying platform 110 above the ground. (See attached diagram.) Figure 1 Appendix Figure 2 and attached Figure 4The support platform 110 is provided with a grid structure 112 composed of multiple grid units 111. In one embodiment, the grid structure 112 is located on the outer side or outer ring of the support platform 110, that is, in the direction close to the edge of the support platform 110. In another embodiment, the support platform 110 is constructed as a grid structure 112 composed of multiple grid units 111, that is, the entire support platform 110 is a grid structure 112, which can enhance exhaust performance and reduce the weight of the support platform. It should be understood that in practical applications, a suitable support platform can be selected according to factors such as the installation position and size of the aircraft rotor. Due to the presence of the grid structure, the exhaust performance of the support platform is greatly enhanced, so that when the aircraft takes off and lands on the support platform 110, the airflow generated by the aircraft rotor below the aircraft can flow out through the grid structure 112 from the space between the support platform 110 and the ground, thereby effectively reducing the ground effect.

[0027] The carrier platform 110 according to the principles of this application can be of any shape. In some embodiments, the carrier platform 110 is circular, or a polygon such as a rectangle, pentagon, hexagon, heptagon, or octagon. In some embodiments, the carrier platform 110 is preferably circular, hexagonal, or octagonal, thereby facilitating aircraft landing and avoiding unnecessary turns by the aircraft to adapt to the shape of the carrier platform during landing. In some embodiments, the carrier platform 110 is preferably square, regular pentagon, regular hexagon, regular heptagon, or regular octagon. Preferably, when the carrier platform 110 is a polygon such as a hexagon or rectangle, the diameter of its circumscribed circle is greater than twice the diameter of the aircraft's circumscribed circle, so that the carrier platform 110 has a sufficiently large take-off and landing area to facilitate aircraft take-off and landing.

[0028] It should be understood that, in this application, "ground" refers to the surface that supports the take-off and landing platform, which can be the earth's surface or other surfaces, such as surfaces set on buildings, vehicles, ships, etc.

[0029] See attached document Figure 3 and attached Figure 4The grid unit 111 includes a first wall 113 and a second wall 114. The first wall 113 extends along a direction passing through the geometric center of the support platform 110. For example, for a circular support platform 110, the first wall 113 extends radially. The second wall 114 extends circumferentially along the support platform 110. For example, for a circular support platform 110, the second wall 114 can be an arc of a circle concentric with the circle; for a hexagonal or other polygonal support platform 110, the second wall 114 can be a straight line parallel to at least one side of the support platform 110. The first wall 113 and the second wall 114 are connected to each other to form the grid unit 111. Advantageously, the lower portion of the second wall 114, i.e., the end closest to the ground, slopes outwards from the support platform 114. This allows the airflow generated below the aircraft during takeoff and landing to flow along the grid unit 111 towards the outside of the support platform 110, reducing gas accumulation on the support platform 110 and further reducing the ground effect. It also facilitates the outward discharge of rainwater during rainy weather.

[0030] See attached document Figure 4 Advantageously, in some embodiments, the horizontal projections of the second walls 114 of the plurality of grid units 111 partially overlap each other. For example, the horizontal projection of the second wall 114a of grid unit 111a is a, and the horizontal projection of the second wall 114b of grid unit 111b is b, with projections a and b partially overlapping at point c. This, on the one hand, prevents the ground from being visible when viewed directly below from above the platform 110, thus preventing personnel on the platform 110 from experiencing acrophobia; on the other hand, it also prevents dust stirred up by airflow on the ground from floating upwards and entering the aircraft, ensuring the cleanliness of the aircraft.

[0031] Preferably, refer to the appendix Figure 1 Appendix Figure 2 and attached Figure 5The aircraft landing platform 100 may also have a lifting platform 130 at its center, so that the carrying platform 110 surrounds the lifting platform 130. Advantageously, the lifting platform 130 has the same shape as the landing platform 100. For example, in the exemplary embodiment shown, both the lifting platform 130 and the landing platform 100 are hexagonal. Both the lifting platform 130 and the landing platform 100 may also be circular, as will be readily understood by those skilled in the art. The top surface 131 of the lifting platform 130 can be raised to be flush with the top surface of the carrying platform 110 to carry personnel or goods. The lifting platform 130 can be used to transport goods or personnel; for example, before the aircraft takes off, personnel or goods can be transported from the ground to the carrying platform 110 via the lifting platform 130 so that the aircraft can carry them away; after the aircraft lands, personnel or goods brought by the aircraft can be transported to the ground via the lifting platform 130, thereby improving transportation efficiency. The lifting platform 130 can be of various types, such as a hydraulic lifting platform, a screw lifting platform, or a chain lifting platform, etc., and this application does not limit this. Advantageously, the top surface 131 of the lifting platform or the load-bearing platform 110 can be painted with visual identification markings so that the aircraft can locate the take-off and landing platform accordingly. The visual identification markings can be letters, numbers, or symbols, or a combination thereof.

[0032] In some embodiments, the lifting platform 130 may be equipped with a charging device (not shown). When the aircraft lands on the landing platform 100, the lifting platform 130 can rise to a position above the landing platform 100 to charge the aircraft. The charging device can be a wired charging device or a wireless charging device. In some embodiments, the charging device is a wireless charging device and can be located on the top surface of the lifting platform 130, allowing the lifting platform 130 to rise to a height that contacts the aircraft, for example, to a height that contacts the aircraft's belly, for wireless charging. In some embodiments, the charging device is a wired charging device, which can be located on the top or side of the lifting platform 130 and charges the aircraft via a charging cable. In these embodiments, the lifting platform 130 can rise to any suitable charging height, without having to rise to a height that allows contact with the aircraft. See attached diagram. Figure 1 and attached Figure 5The aircraft landing platform 100 may also include a safety net 140, which surrounds the support platform 110. The top of the safety net 140, i.e., the end of the safety net 140 away from the ground, is inclined away from the landing platform 130, thereby preventing objects on the landing platform 100 from falling to the ground and causing safety accidents. The safety net 140 is detachably connected to the support platform 140 and / or the support structure 120 by bolts or clips for easy removal. Advantageously, in some embodiments, the top of the safety net 140 is not higher than the support platform 110, thereby avoiding interference with the aircraft taking off and landing.

[0033] See attached document Figure 1 and attached Figure 5 The support structure 120 may include a support beam 121 and a support column 122. The support beam 121 is connected to the load-bearing platform 110 in a horizontal direction to increase the contact area with the load-bearing platform 110. The support column 122 is connected to the support beam 121 in a vertical direction, thereby providing support for the support beam 121 and the entire load-bearing platform 110. This structure makes the support structure 120 more stable in supporting the load-bearing platform 110. In some embodiments, the support beam 121 extends horizontally along a direction passing through the geometric center of the load-bearing platform 110, thereby reducing the impact on the exhaust performance of the grille structure 112. In some embodiments, wheels may be provided at the bottom of the support column 121 to facilitate the movement of the lifting platform.

[0034] The aircraft take-off and landing platform based on the principles of this application can be used for both manned and unmanned aircraft take-off and landing. It can be installed on the ground, buildings, vehicles, ships, etc., to adapt to various application scenarios. The size of the aircraft take-off and landing platform can be determined according to the size of the aircraft it is adapted to.

[0035] The aircraft takeoff and landing platform based on the principles of this application can effectively discharge the airflow generated below the aircraft during takeoff and landing through a grid structure, thereby effectively preventing the ground effect and ensuring smooth takeoff and landing. Furthermore, the aircraft takeoff and landing platform of this application also has good drainage, dust prevention, and acrophobia-reducing functions, enabling it to be used in a variety of application scenarios.
