Description

Technical Field

[0001] This application relates to the field of heavy equipment airdrop, and in particular to a mechanism for suppressing the swaying of airdropped items in mid-air. Background Technology

[0002] During the descent of the airdropped component, the influence of airflow causes some main parachutes to swing excessively, resulting in a "pendulum" phenomenon and increasing the uncertainty of landing safety. Simultaneously, during the approach to the ground, the airdropped component is frequently affected by sudden wind changes due to terrain, temperature, and other environmental factors. Because the group of parachutes consists of multiple large, round canopies, each canopy experiences different effects from these wind changes, easily leading to an imbalance of forces among the parachutes and causing the airdropped component to swing in the air. This swinging affects the landing attitude and speed, thereby increasing the risk of rollover. Summary of the Invention

[0003] One of the purposes of this application is to provide an airdrop component sway suppression mechanism, which aims to solve the problem that existing airdrop components are prone to swaying during the air descent process.

[0004] The technical solution of this application is: An airdrop component sway suppression mechanism includes a sling connector, a release lock, multiple damping connecting ropes, multiple main umbrellas, and multiple first connecting straps. The sling connector is connected to the top of the airdrop component. The release lock is detachably mounted on the sling connector. The multiple damping connecting ropes are connected to the release lock at intervals. The bottoms of the multiple main umbrellas are respectively connected to the corresponding damping connecting ropes. The multiple first connecting straps are arranged crosswise and converge at the same center point, and their two ends are respectively connected to the center of the top of the corresponding main umbrella.

[0005] As one technical solution of this application, the main umbrella includes six umbrellas, which are evenly arranged on the release lock.

[0006] As one technical solution of this application, the main umbrella includes multiple umbrella lines, an umbrella canopy, and an umbrella top; the bottoms of the multiple umbrella lines are connected together, and the tops are respectively connected to the umbrella canopy along the circumference of the umbrella canopy; the umbrella top is located at the top center point of the umbrella canopy and is connected to the corresponding first connecting strip.

[0007] As one technical solution of this application, the damping connecting rope includes a first hanging ring, a second connecting strap, a third connecting strap, and a second hanging ring; the first hanging ring is connected to the release lock; the top and bottom ends of the second connecting strap are respectively connected to the first hanging ring and the second hanging ring; the third connecting strap is retractably connected to the second connecting strap, and its two ends are respectively connected to the first hanging ring and the second hanging ring; the second hanging ring is connected to the bottom of the main umbrella; both the second connecting strap and the third connecting strap are elastic.

[0008] As one technical solution of this application, the elongation of the second connecting strip is greater than that of the third connecting strip.

[0009] As one technical solution of this application, the sling connector includes a textile belt.

[0010] The beneficial effects of this application are: This application provides an airdrop component sway suppression mechanism, which connects multiple main parachutes into one unit via multiple first connecting straps. This allows control over the sway range of the main parachutes, thereby structurally controlling the overall layout of the group of parachutes. This reduces the likelihood of a single main parachute exhibiting inconsistent movement or movement trends with other main parachutes, improving the stability of the airdrop component during airdrop. Simultaneously, multiple damping connecting ropes are designed between the main parachutes and the airdrop component. When a single main parachute exhibits inconsistent movement or movement trends with other main parachutes, these damping connecting ropes reduce the impact of that main parachute on the overall system stability, thus preventing the pendulum phenomenon that occurs during airdrop.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0016] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0017] In the description of this application, it should be noted that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use. They are only used to facilitate the description of this application and to simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0018] Furthermore, in this application, unless otherwise expressly specified and limited, "above or below" the first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Moreover, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0021] Example: Please refer to Figure 1 (Refer to) Figure 2 The diagram shows the reloading and airdrop process of the existing airdrop component 1. In the diagram, the airdrop component 1, the sling connector 2, the release lock 3, the connecting belt, and multiple upper base plates 4 are connected in sequence.

[0022] In response to the issue that airdrop component 1 in heavy equipment airdrops is prone to pendulum-like phenomena in the air near-ground phase due to sudden wind changes, which can cause increased horizontal speed and abnormal landing attitude, leading to rollover during landing, this embodiment provides an airdrop component air swing suppression mechanism to improve the stability of the airdrop component 1's attitude and increase the success rate of airdrops.

[0023] Please refer to Figure 3 (Refer to) Figures 4 to 7This embodiment provides an airdrop component sway suppression mechanism, which mainly includes a sling connector 2, a release lock 3, multiple damping connecting ropes 12, multiple main umbrellas, and multiple first connecting straps 9. The sling connector 2 is connected to the top of the airdrop component 1. The release lock 3 is detachably installed on the sling connector 2. At the same time, the multiple damping connecting ropes 12 are connected to the release lock 3 at intervals. The bottoms of the multiple main umbrellas are respectively connected to the corresponding damping connecting ropes 12. In addition, the multiple first connecting straps 9 are arranged crosswise and converge at the same center point, and their two ends are respectively connected to the center of the umbrella top 8 of the corresponding main umbrella.

[0024] It should be noted that the parachute cluster 5 generally refers to a parachute system composed of three or more main parachutes. The more main parachutes there are, the more frequent the disturbances between them, and the worse the stability of each individual parachute. Therefore, in this embodiment, the parachute cluster 5 uses six main parachutes, each a separate module. Different numbers of main parachutes can be combined to meet the airdrop needs of objects of different weights. The six main parachutes are connected into the parachute cluster 5 by multiple first connecting straps 9, and are evenly distributed on the release lock 3. The parachute cluster 5 ensures that the airdrop component 1 descends at a stable descent speed.

[0025] It should be noted that the main umbrella includes multiple parachute lines 7, a canopy 6, and a canopy top 8. The bottoms of the multiple parachute lines 7 are connected, and their tops are connected to the canopy 6 along its circumference. Simultaneously, the canopy top 8 is located at the center point of the top of the canopy 6 and is connected to a corresponding first connecting strap 9. The multiple first connecting straps 9 connect the tops of the multiple canopies 6 into a unified, stable structure. The length of the first connecting strap 9 is determined based on the positional layout of the canopies 6 when fully open and tangent.

[0026] It should be noted that multiple main umbrellas are connected together by multiple first connecting straps 9, which can control the swing range of multiple main umbrellas and thus control the overall layout of the group umbrella 5 composed of multiple main umbrellas from a structural point of view. This can reduce the movement or movement trend of a single main umbrella that is inconsistent with other main umbrellas and improve the stability of the airdrop component 1 during the airdrop process.

[0027] Furthermore, the damping connecting rope 12 includes a first lifting ring, a second connecting strap 10, a third connecting strap 11, and a second lifting ring; the first lifting ring is connected to the release lock 3; the top and bottom ends of the second connecting strap 10 are respectively connected to the first lifting ring and the second lifting ring; the third connecting strap 11 is telescopically connected to the second connecting strap 10, and its ends are respectively connected to the first lifting ring and the second lifting ring; the second lifting ring is connected to the bottom of the main umbrella; both the second connecting strap 10 and the third connecting strap 11 are elastic. The elongation rate of the second connecting strap 10 is greater than that of the third connecting strap 11. By installing the damping connecting rope 12 between the multiple parachute lines 7 and the airdrop component 1, when a single main umbrella deviates outwards from the other main umbrellas, the damping connecting rope 12 can absorb the outward deflection energy of the main umbrella, reducing the impact of a single main umbrella on the entire airdrop mechanism.

[0028] It should be noted that in this embodiment, the sling connector 2 can be made of textile tape. The damping connecting rope 12 can be extended to a predetermined length, with the elongation increasing by 20%-30% compared to its natural length. The damping connecting rope 12 is made of connecting strips with different elongation rates spliced ​​together. The length of the first connecting strip 9 in its natural state is the natural length of the damping connecting rope 12, and the length of the second connecting strip 10 in its straightened state is the longest length of the damping connecting rope 12.

[0029] Therefore, multiple damping connecting ropes 12 are designed between the main parachute and the airdrop component 1. When a single main parachute exhibits a movement or movement trend inconsistent with other main parachutes, the multiple damping connecting ropes 12 can reduce the impact of the main parachute on the overall system stability, thereby avoiding the pendulum phenomenon that occurs during the airdrop process and reducing the probability of the airdrop component 1 tipping over.

[0030] In summary, the group of parachutes 5 provides a stable descent speed for the airdrop component 1. Due to sudden wind changes, a single main parachute may deviate, generating lateral tension and disrupting the system's stability in the air, causing the airdrop component 1 to exhibit a pendulum-like phenomenon. Therefore, in this invention, a first connecting strap 9 is added to the top 8 of the main parachute to limit the multiple main parachutes within a certain deviation range, thereby reducing the system sway caused by mutual disturbance between the main parachutes. At the same time, a damping connecting rope 12 is added between each main parachute and the release lock 3. When a single main parachute deviates, the damping connecting rope 12 can absorb the energy generated by the lateral deviation of the single main parachute, reducing the impact of the group of parachutes 5 on the release lock 3, thereby ensuring that the airdrop component 1 remains in a stable state.

[0031] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
