[0001] The invention belongs to the application field of airborne systems, and specifically relates to an automatic opening device for a backup parachute and a packaging method thereof. Background Art
[0002] The current parachute system generally allows the skydiver to manually open the backup parachute. When the main parachute fails or other emergency situations occur, the skydiver can pull off the emergency parachute wire rope to fly off the main parachute. At the same time, the main parachute flies off and the backup parachute package is opened through the main and backup linkage device, so that the backup parachute is released from the parachute package and the backup parachute is opened. The skydiver can also pull off the backup parachute pull ring to open the backup parachute package, so that the backup parachute is released from the parachute package and the backup parachute is opened.
[0003] However, the existing reserve parachute opening technology mainly relies on manual operation by the skydiver. When encountering special situations, the skydiver needs to fly off the main parachute and open the reserve parachute in a short time according to the operating specifications. In the actual parachute landing process, the skydiver may be limited by lack of experience or the skydiving may be incapacitated due to the impact of the parachute opening, which increases the risk of accidents. Summary of the invention

[0019] The invention designs an automatic opening device for a backup parachute, improves the parachute bag, and increases the interface between the bag and the electronic automatic opener, so that the parachute has the ability to automatically open the backup parachute.
[0020] The technical solution of the present invention is to improve the parachute bag, add an interface with an electronic automatic parachute opener, including a backup parachute opener protection bag, a wire fixing cloth, a wire sleeve and other components, and utilize the function of the electronic automatic parachute opener to enable the parachute to have automatic opening capability.
[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] In order to make the parachute have the ability to open automatically, new wire fixing cloth (the quantity and length are determined by the cable length between the handheld device 1 and the main controller 2), wire sleeves (the quantity and length are determined by the cable length between the cutter 3 and the main controller 2), a backup parachute opener protection bag, and openings (the quantity is determined by the parachute bag structure) are added to the parachute bag.
[0023] The present invention takes a double parachute bag as an example to illustrate the improvement scheme of the parachute bag. Other backup parachute bags with single-point sealing can also realize the automatic opening function according to this method. Electronic automatic parachute opener ( Figure 1 ) is usually composed of three parts: a handheld device 1, a main controller 2 and a cutter 3. Its function is to automatically cut off the backup parachute packing rope 4 and open the backup parachute when the main parachute fails and the parachutist fails to open the backup parachute above the minimum safe altitude. The conventional packing method of the backup parachute is single-point packing. The backup parachute packing rope 4 is tied to the main part of the backup parachute bag ( Figure 2 ) is protected by the rope loop protection belt 6 to prevent the backup parachute packing rope 4 from falling off during the use of the parachute pack. The backup parachute packing rope 4 passes through the main part of the backup parachute pack ( Figure 2) The two eye ring bodies 7 on the left and right sides are placed outside the backup parachute bag to achieve the effect of sealing. In order to adapt to the electronic automatic parachute opener, a wire sleeve 8 is set at a distance of 10mm to 20mm from the center of the single-side eye ring body 7. The length of the wire sleeve 8 is determined by the length of the cutter 3, and should be able to wrap the remaining part of the cutter 3 after the rope threading hole is exposed. The material of the wire sleeve 8 is generally a retractable elastic band, which is convenient for fixing the cutter 3 and can adapt to different sizes of the cutter 3. The cutter 3 is placed in the wire sleeve 8, and the backup parachute sealing rope 4 passes through the left and right eye ring bodies 7 to the outside of the parachute bag in turn and then passes through the rope threading hole on the cutter 3 for sealing.
[0024] A backup parachute opener protection bag 12 is provided on the backup parachute bag at a position that does not interfere with normal parachuting behavior. It can usually be provided at the bottom of the backup parachute bag or at the lower end of the backup parachute bag. The backup parachute opener protection bag 12 is used to place the main controller 2. The position is not uniquely fixed. It is designed based on the structure of different bags and on the premise of not affecting the opening of the backup parachute. The shape of the backup parachute opener protection bag 12 is determined according to the shape of the main controller 2. It is usually a rectangular pocket of the same size as the main controller 2. There is a wire protection cloth 13 at the upper end to protect the cables leading out from the main controller 2. In the example, the backup parachute opener protection bag 12 is provided at the bottom of the backup parachute bag of a double parachute bag, that is, the protective cloth on the bag ( Figure 3 ). After the main controller 2 is loaded into the reserve parachute opener protection bag 12, the cable connecting the handheld device 1 and the cutter 2 passes through the opening 14 on the protective cloth on the parachute bag. The shape of the opening 14 is not fixed. It can be a long strip opening, or a square or round opening. The size is based on the ability to pass through the handheld device 1 and the cutter 3. The position is not mandatory and is determined by the direction of the cable. In the example, the position of the opening 14 is located 25 mm above the reserve parachute opener protection bag 12. According to the cable length between the cutter 3 and the main controller 2, a wire sleeve 2 9, a wire sleeve 3 10, and a wire sleeve 4 11 are set. The function of the wire sleeve 2 9 to the wire sleeve 4 11 is to bind, hide and guide the cable. The length varies from 20 mm to 100 mm. It can also be appropriately extended according to the cable length and the width of the parachute bag. The position is usually set along the edge of the reserve parachute bag to reduce the risk of cable entanglement. The cable passes through the wire sleeve 2 9 to the wire sleeve 4 11 on the main part of the reserve parachute bag in sequence until the cutter 3 is placed in the wire sleeve 1 8. The redundant cables can be folded and placed in the wire sleeve 2 9 to the wire sleeve 4 11. The wire sleeve 2 9 to the wire sleeve 4 11 are not necessary components. If the cables between the cutter 3 and the main controller 2 can be buried in the umbrella bag interlayer, the wire sleeve 2 9 to the wire sleeve 4 11 can be cancelled.
[0025] After the cable of the handheld device 1 passes through the opening 14 of the upper protection part of the umbrella bag, it is guided from the umbrella bag to the umbrella protection part ( Figure 4) The shape of the second opening 16 is not fixed, and it can be a long strip opening, or a square or round opening. The size is based on the ability to pass through the handheld device 1. The position is not mandatory and is determined by the direction of the cable. In the example, the second opening 16 is located 15mm to the left of the protective bag 17. After the handheld device 1 passes through the second opening 16, it is placed in the protective bag 17. The protective bag 17 is usually a rectangular transparent film of 45mm×85mm. The size of the protective bag 17 can be appropriately increased or reduced according to the size of the handheld device 1. When performing a parachuting mission, the digital display on the handheld device 1 can be observed through the transparent film without opening the protective bag 17. The redundant cables can be folded and placed in the wire fixing cloth 15 of the protective part of the parachute bag. The wire fixing cloth is a rectangular structure with a non-fixed size. In the example, it is 55mm×75mm. In practice, it can be appropriately increased or reduced according to the length of the redundant cables. The wire fixing cloth 15 is not a necessary component. If the cable between the handheld device 1 and the main controller 2 can be buried in the interlayer of the parachute bag, the wire fixing cloth 15 can be cancelled.
[0026] When the skydiver installs the electronic automatic parachute opener during the parachute folding process, he first puts the main controller 2 into the backup parachute opener protection bag 12 of the protective cloth on the parachute bag. Insert the two cables into the opening 14 of the protective cloth on the parachute bag without crossing each other. The cable of the cutter 3 is inserted in sequence from the wire sleeve 29 to the wire sleeve 4 11 at the edge of the main part of the backup parachute bag, and the excess wire is folded and placed in the wire sleeve 29 to the wire sleeve 4 11. Pass the cutter 3 through the wire sleeve 1 8, and align the rope threading hole with the eye ring body. The handheld device 1 is inserted from the opening 2 16 of the parachute guide umbrella protection part of the parachute bag, and is placed in the protective bag 17 on the parachute guide umbrella protection part of the parachute bag. The front of the display screen of the handheld device 1 faces the transparent film side. The excess cable is folded and stuffed into the wire fixing cloth 15 of the upper protection part of the parachute bag.
[0027] Before performing a parachuting mission, the skydiver should check whether the electronic automatic parachute opener is working properly. This can be done by checking the display screen on the handheld device 1 and checking according to the instruction manual of the electronic automatic parachute opener. During the parachuting process, if the skydiver reaches the preset minimum rescue altitude and fails to open the backup parachute due to an accident, the electronic automatic parachute opener will work, the cutter 3 will cut the backup parachute package rope 4, and the backup parachute bag will open. After the backup parachute falls out of the bag, it will contact the airflow and start to inflate. After the backup parachute is inflated, it can glide stably to ensure the safety of the skydiver.
[0028] The invention has been tested and verified, and has been put into use. The product has good performance and can meet various index requirements.
