Description

Technical Field

[0001] The invention belongs to the technical field of airborne airdrop, and specifically, relates to a method for bundling and arranging multiple main parachutes in a limited space. Background Art

[0002] During the airdrop process, the main parachute system generates the main aerodynamic force to achieve a stable landing of the airdrop system at a predetermined descent speed. Before the airdrop is implemented, the main parachute system needs to be bundled and arranged on the top of the cargo platform in a certain way, connected to the upstream and downstream components, and all connecting ropes are arranged in order above the main parachute system.

[0003] There is no corresponding main parachute system layout plan for large-tonnage heavy-duty airdrop systems. Currently, there is only an arrangement of less than 5 main parachute systems for small-tonnage airdrop systems.

[0004] As the number of main parachutes required for large-tonnage heavy-duty airdrop systems has greatly increased, the existing arrangement scheme for main parachutes with a number of 5 or less can no longer meet its requirements, and the arrangement method of the connecting ropes cannot be used anymore. Therefore, simply arranging the main parachutes according to the previous rules not only cannot meet the space requirements above the cargo platform and the aircraft cabin, but also cannot meet the synchronization requirements of opening a large number of main parachutes at the same time. Summary of the invention

[0005] The object of the present invention is to provide a method for bundling and arranging multiple main parachutes in a limited space, so as to solve the problem of bundling and arranging 6 to 9 main parachutes on a cargo platform within the required space size.

[0006] The technical solution to achieve the purpose of the present invention is: a method for bundling and arranging multiple main parachutes in a limited space, where every two or three main parachutes are a whole, which are firmly tied together by straps, mooring buckles, and pull-pin ropes, and auxiliary guide parachute bags and connecting ropes are arranged on the top.

[0007] Furthermore, the specific implementation steps are as follows:

[0008] First, on the upper surface of the main parachute stacking position, the first strap is installed in a mesh form as a fixed base point of the main parachute system; for each intersection point as a base point, two second straps are inserted along the diagonal line, each of which is connected to its own end to form a ring, and a mooring rope buckle is connected thereon; in this way, two second straps can be extended from each base point for binding the main parachute, and each set of second straps is used to tighten two to three main parachute bags;

[0009] Then, place the second bundle of straps with the mooring rope buckles on both sides respectively, place a group of packaged main parachute packs between the intersections of the first bundle of straps. Each group of main parachute packs consists of two to three main parachute packs. Pull up the second bundle of straps, pass one mooring rope buckle through the other, and then insert the pins of the pull-out pins into the mooring rope buckles respectively towards the heading, and place them at the middle position on top of the parachute packs. Tighten this group of second bundle of straps evenly. Thus, the bundling and mooring of a group of main parachute packs is completed.

[0010] Further, for the bundling and arrangement of 6 to 9 main parachute systems, divide them into several groups with two to three main parachute packs as a group, and bundle and arrange several groups of main parachute packs on the upper surface of the stacking position according to the following arrangement method:

[0011] For 6 main parachutes: Divide every three main parachute packs into a group, with a total of two groups; each group of main parachute packs is in a "pin" shape, with two placed side by side at the bottom and one lying on its side above; the two groups of main parachute packs are placed side by side;

[0012] For 7 main parachutes: First, divide three main parachute packs into a group and place them side by side in the middle position; for the remaining four main parachute packs, divide them into two groups with two in each group; each group of main parachute packs is in a "lv" shape and is stacked and placed lying on its side; place the latter two groups of main parachute packs symmetrically on the left and right sides of the first group of main parachute packs respectively;

[0013] For 8 main parachutes, divide every two main parachute packs into a group, with a total of four groups; each group of main parachute packs is in a "lv" shape and is stacked and placed lying on its side; the four groups of main parachute packs are placed side by side;

[0014] For 9 main parachutes, divide every three main parachute packs into a group, with a total of three groups; each group of main parachute packs is in a "pin" shape, with two placed side by side at the bottom and one lying on its side above; the three groups of main parachute packs are placed side by side.

[0015] Further, the strap is composed of a first strap and a bundling and untying buckle connected.

[0016] Further, the pull-out pin rope is composed of a second strap and a pin. A section in the middle of the second strap is double-layered, and one end of the ring of the pin passes through one of the layers; both ends of the second strap are looped, and the loop at one end is connected to a pin.

[0017] Compared with the prior art, the remarkable advantages of the present invention are: The dense and reliable bundling form ensures that the main parachute system for heavy airdrop meets the requirements of the internal external contour size of the aircraft cabin, and at the same time reduces the distance between each main parachute pack, making the parachute opening synchronization of the group of parachutes better.

[0027] The present invention aims to design a method for tying and arranging more than 5 main parachutes on a large-tonnage cargo platform, which mainly includes a method for tying and arranging 6 to 9 main parachutes on a cargo platform, and arranging auxiliary guide parachute bags and various connecting ropes on the top so that they do not interfere with each other and do not twist each other.

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] Every two or three main parachutes are a whole, which are firmly tied by straps, tie-down rope buckles and pin ropes. Auxiliary guide parachute bags and connecting ropes are arranged on the top, which do not interfere with each other or twist. It also meets the relatively narrow space requirements above the cargo platform and in the aircraft cabin, and ensures the synchronization of the main parachute system.

[0030] Main parachute installation method:

[0031] First, on the upper surface of the main parachute stacking position, Figure 1 The first strap 1 is installed in a mesh form as shown, which serves as a fixed base point of the main parachute system. For each intersection point as a base point, as shown in FIG. Figure 1 As shown, two second straps 2 are inserted diagonally, each connected to its own end to form a ring, and a tie-down rope buckle is connected thereon. In this way, two second straps 2 can be extended at each required base point for tying the main parachute, and each set of second straps 2 is used to tighten two to three main parachute bags.

[0032] Then, place the second bundle of straps 2 with the mooring rope buckles on both sides respectively. Place the packaged set of main parachute packs between the intersection points of the first bundle of straps 1. Each set of main parachute packs consists of two to three main parachute packs according to the method described later. Pull up the second bundle of straps 2, pass one mooring rope buckle through the other, and then insert the pins of the pull-out pins into the rope buckles respectively towards the heading, and place them in the middle position on top of the parachute packs. Tighten this set of second bundle of straps 2 evenly. Thus, the bundling and mooring of one set of main parachute packs is completed.

[0033] For the bundling arrangement of 6 to 9 main parachute systems, divide them into several groups with two to three main parachute packs as a group according to the following arrangement method, and bundle and arrange several groups of main parachute packs on the upper surface of the stacking position:

[0034] For 6 main parachutes: Divide every three main parachute packs into a group, with a total of two groups. Each group of main parachute packs is in a "pin" shape, with two placed side by side at the bottom and one lying on its side above. The two groups of main parachute packs are placed side by side.

[0035] For 7 main parachutes: First, divide three main parachute packs into a group and place them side by side in the middle position. Divide the remaining four main parachute packs, with two in each group, for a total of two groups. Each group of main parachute packs is in a "lv" shape and is stacked and placed lying on its side. Place the latter two groups of main parachute packs symmetrically on the left and right sides of the first group of main parachute packs respectively.

[0036] For 8 main parachutes, divide every two main parachute packs into a group, with a total of four groups. Each group of main parachute packs is in a "lv" shape and is stacked and placed lying on its side. The four groups of main parachute packs are placed side by side.

[0037] For 9 main parachutes, divide every three main parachute packs into a group, with a total of three groups. Each group of main parachute packs is in a "pin" shape, with two placed side by side at the bottom and one lying on its side above. The three groups of main parachute packs are placed side by side.

[0038] After the main parachutes are installed, the bundling arrangements for each quantity are as Figure 3-6 shown.

[0039] The method of the present invention has been verified by heavy airdrops with large tonnage, and its performance meets the design requirements. It has the airdrop capacity for 9 main parachutes and within, and meets the bundling arrangement requirements on the cargo platform.

[0040] In summary, the present invention is a method for bundling and arranging main parachutes applicable to heavy airdrops with large tonnage. This method can meet the bundling and arrangement of a large number of main parachutes in a large-tonnage airdrop system in a limited space, and meet the requirements of the main parachute system's parachute-opening procedure and synchronization.
