Abstract
Description
Technical Field
[0001] This invention belongs to the field of airdrop technology, and particularly relates to an integrated, tiered, deployable parachute system. Background Technology
[0002] In the field of airdrop, the main role of a cluster parachute system is to provide sufficient drag to enable the airdropped product to land steadily at a limited speed, while meeting constraints such as packaging volume and weight restrictions, thus ensuring the safety of the product landing.
[0003] Traditional swarm systems combine multiple round umbrellas. During operation, the swarm system is pulled out and straightened by a tractor or rocket, and the umbrellas open under the action of airflow. The synchronicity of the opening is affected by factors such as the straightening system and the closing system. This may result in the swarm system affecting each other, causing individual umbrella systems to fail or the umbrella systems to be damaged one by one due to uneven stress. Summary of the Invention

Detailed Implementation
[0022] The present invention is achieved through the following technical solution.
[0023] An integrated, tiered, deployable umbrella system includes a central umbrella system and several edge umbrellas 3, such as Figure 1 and Figure 2 As shown, the edge umbrellas 3 are evenly distributed on the outer edge of the central umbrella system and connected to the edge umbrellas by the connecting strip 2. The outer edge of the central umbrella system has the same number of straight sections as the edge umbrellas, and connects to the edge umbrellas at these straight sections. In this embodiment, four edge umbrellas 3 are provided, and the outer edge of the central umbrella system has four straight sections.
[0024] Each edge umbrella 3 has several edge umbrella lines 4 connected to its lower edge. The edge umbrella lines 4 on each edge umbrella 3 converge at a point and are connected to one end of the control connection line 6. The other ends of the control connection lines 6 connected to each edge umbrella 3 converge at a point. One end of the control connection line 2 is connected to the convergence point of the control connection lines 6, and the other end is connected to the airdropped product.
[0025] The central umbrella system is placed inside the central umbrella pack 8. The central umbrella pack 8 has the same number of slits 10 as the edge umbrellas, and several connecting rope clips 12 are connected to the slits 10.
[0026] Edge umbrellas 3 are placed in edge umbrella packs 9 evenly distributed circumferentially outside the central umbrella pack 8, with one edge umbrella 3 in each edge umbrella pack 9. Each edge umbrella pack 9 is connected to the central umbrella pack 8. Each edge umbrella pack 9 has a second slit 11, which corresponds to the position of the first slit 10. The intersection point of the paracords 4 of each edge umbrella is elastically secured to the connecting rope clamp point 12 at the lower end of the second slit 11. The connecting straps 2, which are connected to the edge umbrellas, are placed sequentially at the connecting rope clamp point 12 at the corresponding first slit 10 of the edge umbrella 3 and are elastically secured by the connecting rope clamp point 12. During overall packaging, the intersection point of the paracords 4 of each edge umbrella is connected to the end of the control connecting rope 6. In this embodiment, the shape of the edge umbrella 3 after being laid flat is semi-circular.
[0027] It also includes several control separation modules 5, which are placed below the central umbrella system 1 inside the central umbrella pack 8. The control connecting ropes 6 connecting each edge umbrella pass through the control separation modules 5 and are elastically secured to the connecting rope locking point 12 at the bottom of the slit 10. In this embodiment, the control separation module 5 includes a rope strap that can secure the control connecting ropes 6 and a cutter set on the rope strap.
[0028] The edge umbrella 3, edge umbrella pack 9, central umbrella system 1, and central umbrella pack 8 are designed as a single unit.
[0029] The top surface of the central parachute pack 8 can be opened, and the central parachute system's top surface is connected to a parachute rocket or a guide chute. Using a pull-out method, the guide chute or parachute rocket pulls out the central parachute system 1, causing the entire parachute system to detach from the parachute pack. Figure 3 As shown.
[0030] When the group parachute system is pulled out, the control separation module 5 is pulled apart from the central parachute pack 8, and the control separation module 5 is activated. At this time, the control separation time is zero.
[0031] The umbrella system inflates and unfolds under the action of airflow. The control separation module 5 controls the movement of the parachute ropes to keep the umbrella system in a closed inflation state.
[0032] When the preset separation conditions are met, the separation module 5 releases the constraint on the control connecting rope 6. In this embodiment, the rope is cut with a cutter, and the umbrella system is further inflated and deployed.
[0033] By setting multiple control separation modules 5, the cluster parachute system can be deployed in stages. The control separation modules 5 are set at different heights, and multi-stage control can achieve the effects of load reduction and synchronous parachute opening.
[0034] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be used to limit the scope of protection of the present invention. All equivalent transformations or modifications made according to the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
