Description

Technical Field

[0001] The invention belongs to the field of airdrop, and in particular relates to a parachute packaging container for towing airdrop. Background Art

[0002] When large transport aircraft airdrop heavy equipment, due to its heavy weight, a tow-out airdrop method is typically used. This method relies on the tow parachute in the tow system to generate a constant force to safely pull the equipment out of the aircraft cabin. The tow system generally includes a guide parachute, a tow parachute, a tow rope, and a packaging container, which must accommodate other components besides the packaging itself. During a tow-out airdrop, the reliability of the tow system is crucial to both aircraft and equipment safety. Ensuring the tow system's safe departure, rapid exit from the aircraft's wake, and smooth deployment of the tow parachute are key to tow-out airdrops. However, the following challenges currently exist:

[0003] 1) Generally, the length of a towing rope is 5 to 7 times the maximum diameter of the aircraft fuselage. The length of a towing rope suitable for large aircraft is generally greater than 30 meters, and is commonly around 50 meters. This allows the towing parachute to avoid the aircraft's wake and work normally. Current packaging containers cannot ensure that excessively long towing ropes can be straightened in an orderly manner, and towing parachutes generally have a small area. If the towing rope is packaged in a "clump" and entangled, the guide parachute and the towing parachute are easily affected by the aircraft's wake, resulting in a failure to tow out the aircraft. At this time, the equipment in the aircraft cabin is still connected to the towing system, which poses a threat to the aircraft's control stability and the safety of the system.

[0004] 2) The current packaging container is large and its volume cannot be adjusted after packaging. The packaging container is divided into two cavities and is only constrained by blades. The traction rope is generally made of multi-layer and multi-strand brocade ribbon. Therefore, the packaging density is low and it is not suitable for accommodation in a small space. In addition, the traction rope needs to be manually combed and placed, which makes the packaging complicated and takes a long time. In addition, it is not easy to check after packaging. If it is not packed properly, it needs to be taken out and repacked, and the fault tolerance is not strong.

[0005] 3) The current packaging container cannot be installed firmly, so its posture is unstable. Summary of the Invention

[0006] The purpose of the present invention is to provide a parachute packaging container for towing airdrop, which can prevent excessively long towing ropes from being disorderly unpacked and entangled, can adjust the volume, is simple and practical to operate, and can be stably installed.

[0007] The technical solution adopted in the present invention is:

[0008] A parachute packaging container for towing airdrop comprises a rectangular main part made of fabric and a fixing plate with an interface, wherein the two outer surrounding edges of the main part are provided with tightening buckles, the two outer closing edges are provided with restraining buckles, the middle outer part is provided with an adjusting belt and an adjusting buckle, the inner side is provided with a honeycomb rope sleeve, the inner honeycomb rope sleeve is provided with an umbrella cavity at one end in the closing direction, and the umbrella cavity is provided with a sealing rope buckle and a sealing buckle; when installed, the main part passes through the honeycomb rope sleeve to restrain the towing rope, the umbrella cavity is accommodated by the towing parachute, the umbrella cavity is sealed by the sealing rope buckle and the sealing buckle, the tightening belt buckle cooperates with the packaging rope to enclose the cylinder, the two ends of the cylinder are closed by cooperating with the packaging rope, the tightening belt buckle cooperates with the packaging rope to connect the guide parachute, the volume of the cylinder is adjusted by the adjusting belt and the adjusting buckle and connected to the fixing plate, and the fixing plate is installed on the aircraft lock through the interface.

[0009] Furthermore, a handle for carrying is provided on the outside of the main part.

[0010] Furthermore, a reinforcement belt is provided on the main portion.

[0011] Furthermore, the interface is in the shape of a U-shaped ring and is inserted and welded to the fixing plate.

[0012] The beneficial effects of the present invention are:

[0013] The towing rope is constrained by the honeycomb-shaped rope loop. The number of loops through which the towing rope is inserted adjusts the reserved length of the towing rope, adapting it to the fixed position of the equipment on the aircraft's central rail and preventing the disorderly unpacking of excessive lengths that could cause entanglement. Once installed, the packaging container not only encloses the towing rope and towing parachute, preventing them from being exposed and potentially snagging, but also allows for adjustable volume to fit into the aircraft's confined spaces, such as a bomb bay. The two ends can also be opened to form inspection windows for easy and practical operation. A fixing plate ensures the packaging container is securely installed and maintains a stable posture, preventing violent shaking in airflow. The cord lock controls the canopy's straightening process and releases the canopy's seal. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings and examples.

[0027] like Figures 1 to 11 As shown, a parachute packaging container for towing airdrop includes a rectangular main part 7 made of fabric and a fixing plate 12 with an interface 13. The two outer surrounding edges of the main part 7 are distributed with tightening buckles 2, the two outer closing edges are distributed with restraining buckles 1, the middle part of the outer side is provided with an adjusting belt 5 and an adjusting buckle 4, the inner side is provided with a honeycomb rope sleeve 8, and the inner honeycomb rope sleeve 8 is provided with an umbrella cavity 9 at one end in the closing direction. The umbrella cavity 9 is provided with a package rope buckle 10 and a package buckle 11; when installed, the main part 7 is connected to the main part 7 by The honeycomb-shaped rope sleeve 8 passes through the restraining traction rope 15, accommodates the traction parachute through the parachute cavity 9, seals the parachute cavity 9 through the sealing rope buckle 10 and the sealing buckle ring 11, and is enclosed into a cylinder by tightening the belt buckle 2 and cooperating with the packaging rope 16. The two ends of the cylinder are closed by tightening the belt buckle 1 and cooperating with the packaging rope 16, and the guide parachute is connected by tightening the belt buckle 2 and cooperating with the packaging rope 16. The volume of the cylinder is adjusted by adjusting the belt 5 and the adjusting buckle 4 and connected to the fixing plate 12. The fixing plate 12 is installed on the aircraft lock through the interface 13.

[0028] The traction rope 15 is constrained within the honeycomb-shaped tie rope sleeve 8. The number of times the traction rope 15 is inserted into the honeycomb-shaped tie rope sleeve 8 allows for adjustment of the reserved length of the traction rope 15, adapting to the fixed position of the equipment on the aircraft's central rail and preventing the uncontrolled unloading of the traction rope 15, which could cause entanglement. Once installed, the packaging container not only encloses the traction rope 15 and the traction parachute, preventing them from being exposed and potentially snagging, but also allows for adjustable volume to fit within the aircraft's confined spaces, such as a bomb bay. The two ends can also be opened to form inspection windows 14 for easy inspection, making it simple and practical to operate. The fixing plate 12 ensures a secure installation and a stable posture for the packaging container, preventing it from shaking violently in airflow. The closure cord buckle 10 controls the canopy's straightening process and releases the canopy's closure.
