Description

Technical Field

[0001] This application belongs to the field of aircraft arresting technology, specifically a sinking aircraft arresting net. Background Technology

[0002] Currently, all aircraft arresting net equipment is ground-based, and its main structure can be found in two patents: ZL201810838045.4 (Aircraft Arresting Equipment) and ZL201810838453.X (Arresting Equipment). Aircraft arresting net equipment is primarily used to ensure the safe takeoff and landing of PLA aircraft. When not in operation, the overall height of the equipment is approximately 1.3 meters. In recent years, with the deep integration of military and civilian airport support work, the deployment of military aircraft to civilian airports and the use of joint military-civilian airports to support military aircraft takeoffs and landings have become increasingly common. According to the Civil Aviation Administration, Article 4.5.5 of the Civil Aviation Administration document MH5001-2021, "Technical Standards for Flight Areas of Civil Airports," stipulates that "equipment and facilities placed within the runway end safety zone that are necessary to ensure flight safety or for aircraft safety purposes should meet the requirements of fragility; other objects that may pose a danger to aircraft should be considered obstacles and removed as much as possible." The protruding ground structures of the currently operational Air Force aircraft arresting net equipment are considered obstacles, posing a safety hazard to civilian aircraft that overrun the runway.

[0003] In 2024, a Jeju Air Boeing 737 passenger plane veered off the runway while landing at an airport in South Jeolla Province, South Korea, and crashed into a concrete wall obstacle at the southern end of the runway that was higher than the ground. An explosion ensued, killing all 179 people on board except for two who survived. This incident once again brought the issue of obstacles affecting the safety of civil aviation aircraft to the forefront of public attention. Summary of the Invention

[0004] This application mainly adjusts the vertical grid frame assembly, electrical control box assembly, guide wheel assembly, mesh belt connector assembly, and energy absorber assembly to solve the problem that the aircraft arresting net equipment becomes an obstacle affecting the flight safety of the aircraft when it is not in operation.

[0005] (1) Structural form of sinking aircraft arresting net equipment. It mainly consists of electrical control box component tunnel, electrical control box, vertical net frame component tunnel, energy absorber component tunnel, pressure roller assembly, belt winding mechanism, guide wheel assembly, vertical net frame assembly, brake band, net belt connector assembly, net body assembly, etc.

[0006] (2) Overall layout of the sinking aircraft arresting net equipment. Based on the working principle of the sinking aircraft arresting net equipment, the energy absorber components, guide wheel components, etc. are arranged more compactly and closer to the vertically placed net frame components.

[0007] (2) Working mode of the sinking aircraft arresting net equipment. When not in operation, the sinking aircraft arresting net equipment can be fully sunk into the ground and kept flush with the ground by the cover plate, becoming an obstacle that does not affect flight safety; when in operation, the vertical net frame assembly can hang the net to a suitable height to complete the arresting function.

[0008] According to one aspect of this application, a sinking aircraft arresting net is provided, comprising an electrical control box assembly tunnel 1, an electrical control box 2, a vertically placed net frame assembly tunnel 3, an energy absorber assembly tunnel 4, a pressure roller assembly 5, a belt take-up mechanism 6, an energy absorber assembly 7, a guide wheel assembly 8, a vertically placed net frame assembly 9, a brake band 10, a net belt connector assembly 11, a net body assembly 12, a brake band connecting cylindrical shaft 13, a net body connecting cylindrical shaft 14, a vertically placed net frame assembly tunnel cover 15, a vertically placed net frame assembly working window 16, an electrical control box assembly tunnel cover 17, an electrical control box assembly working window 18, an energy absorber assembly working window 19, and an energy absorber assembly tunnel cover 20.

[0009] The electrical control box 2 is fixed in the electrical control box assembly tunnel 1 by pre-embedded bolts;

[0010] The vertical space frame assembly 9 is fixed in the vertical space frame assembly tunnel 3 by pre-embedded bolts;

[0011] The pressure roller assembly 5, the belt winding mechanism 6, the energy absorber assembly 7, and the guide wheel assembly 8 are fixed in the energy absorber assembly tunnel 4 by pre-embedded bolts;

[0012] The upper part of the electrical control box assembly tunnel 1 is equipped with an H-shaped steel frame electrical control box assembly tunnel cover plate 17.

[0013] The vertical space frame assembly 9 is equipped with an H-shaped steel frame tunnel cover plate 15.

[0014] The upper part of the energy absorber assembly tunnel 4 is equipped with an H-shaped steel frame energy absorber assembly tunnel cover plate 20.

[0015] The electrical control box assembly tunnel cover 17 is provided with an electrical control box assembly working window 18, which is used for simple daily maintenance and repair, as well as to perform control operations.

[0016] The tunnel cover plate 15 of the vertically placed mesh frame assembly is provided with a working window 16 for the vertically placed mesh frame assembly, which is used for manual vertical mesh placement operation and simple daily maintenance and repair.

[0017] The energy absorber assembly tunnel cover 20 is provided with an energy absorber assembly working window 19 for simple daily maintenance and repair, as well as for performing belt retraction work.

[0018] The vertical mesh frame components 9 on both sides are a certain distance apart. The mesh body component 12 is suspended between the vertical mesh frame components 9 on both sides. The vertical mesh frame components 9 are raised and lowered by a motor. When the vertical mesh frame components 9 are lowered, the entire vertical mesh frame components 9 sinks into the vertical mesh frame component tunnel 3 and remains flush with the ground.

[0019] The lower part of the mesh assembly 12 is connected to the brake band 10 through the mesh belt connector assembly 11. After the other end of the brake band 10 enters the energy absorber assembly tunnel 4, it is adjusted by the guide wheel assembly 8 and then coiled around the energy absorber assembly 7. The pressure roller assembly 5 ensures that the brake band 10 does not slip.

[0020] After the aircraft hits the net, the retraction mechanism 6 is used to retrieve the brake band 10 and rewrap it around the energy absorber assembly 7. The retraction mechanism 6 is motor controlled.

[0021] The motors used in the vertical mesh frame assembly 9 and the motors used in the winding mechanism 6 are both connected to the electrical control box assembly tunnel 1 via wiring, and then connected to the electrical control box 2 for control.

[0022] The mesh assembly 12 is connected to the brake band 10 through the mesh belt connector assembly 11. After the mesh assembly 12 is looped, it is connected to the mesh connecting cylindrical shaft 14 on one side of the mesh belt connector assembly 11. The brake band connecting cylindrical shaft 13 on the other side of the mesh belt connector assembly 11 is connected to the loop of the brake band 10.

[0023] The function of the mesh belt connector assembly 11 is to connect the mesh assembly 12 to the brake band 10, so that when the mesh assembly 12 moves forward due to the impact of the aircraft, it can drag the brake band 10 to make the energy absorber assembly 7 work, generate the corresponding arresting torque, and stop the aircraft.

[0024] After the brake band 10 enters the energy absorber assembly tunnel 4, it changes from horizontal to vertical through the guide wheel assembly 8, and changes from the horizontal ground height to the height of the brake band disc of the energy absorber assembly 7. Finally, it wraps around the brake band disc of the energy absorber assembly 7, and relies on the pressure roller assembly 5 to prevent slippage.

[0025] The function of the brake band 10 is to ensure the smooth transfer of energy;

[0026] The function of the guide wheel assembly 8 is to change the direction of the force transmitted by the brake band 10, so as to achieve the purpose of absorbing energy using the energy absorber assembly 7;

[0027] The energy absorber assembly 7 is the core component, and its function is to generate arresting torque to stop the aircraft.

[0028] When the aircraft hits the net, the brake band 10 moves forward together with the net assembly 12 and the aircraft and disengages from the brake band disc of the energy absorber assembly 7. The brake band 10 is then retrieved using the band retraction mechanism 6.

[0029] The winding mechanism 6 and the upright net frame assembly 9 both use motors as power sources. Their power lines are connected to the electrical control box assembly tunnel 1 through underground pipelines and are connected to the electrical control box 2.

[0030] The advantages of this application are:

[0031] The sinking aircraft arresting net equipment of this application, due to the setting of the tunnel, can be completely sunk underground when not in operation. At the same time, under the protection of the tunnel cover, various types of aircraft, emergency vehicles, etc. are allowed to pass normally in the layout area of ​​the aircraft arresting net equipment, so that the aircraft arresting net equipment does not become a height-dependent obstacle that affects flight safety.

[0043] The present application is described in detail below with reference to the embodiments, but the present application is not limited to these embodiments.

[0044] Example 1

[0045] A sinking-type aircraft arresting device mainly consists of 11 parts: an electrical control box assembly tunnel, an electrical control box, a vertically placed mesh frame assembly tunnel, an energy absorber assembly tunnel, a pressure roller assembly, a belt take-up mechanism, a guide wheel assembly, a vertically placed mesh frame assembly, a brake band, a mesh belt connector assembly, and a mesh body assembly. The mesh belt connector assembly, vertically placed mesh frame assembly, electrical control box assembly, guide wheel assembly, and energy absorber assembly are all placed in the tunnel. A tunnel cover is laid on top of the tunnel, ensuring that the cover is flush with the perimeter and does not obstruct the normal passage of aircraft.

[0046] The positions and connections between the various parts are as follows: The two vertical mesh frame components are spaced a certain distance apart. The mesh body component is suspended between these components, and its erection and lowering are controlled by motors. When lowered, the entire vertical mesh frame component sinks into its trench, remaining flush with the ground. The lower part of the mesh body component is connected to a brake band via a mesh belt connector assembly. The other end of the brake band enters the energy absorber component trench, where it is adjusted by guide wheels and then coiled around the energy absorber component. Pressure rollers ensure the brake band does not slip. When the aircraft hits the mesh, a retraction mechanism is used to retrieve the brake band and rewrap it around the energy absorber component. This retraction mechanism is motor-controlled. Both the motors used in the vertical mesh frame components and the motors used in the retraction mechanism are connected via wiring to the electrical control box assembly trench, which then controls their respective operations.

[0047] The mesh assembly is connected to the steel cables of the vertical mesh frame assembly via a shear separator.

[0048] The vertical space frame assembly is fixed inside the vertical space frame assembly tunnel using pre-embedded bolts. A cover plate with an H-shaped steel frame is installed on the upper part of the tunnel. The main function of the tunnel cover plate is to ensure that the vertical space frame assembly, when not in operation, is level with the surrounding ground after being lowered, and to allow vehicles and aircraft to pass smoothly over it. The tunnel cover plate is equipped with a working window for manual operation of the vertical space frame assembly and simple routine maintenance.

[0049] The mesh assembly is connected to the brake band via a mesh belt connector assembly. The mesh assembly, after forming a loop, is connected to a cylindrical shaft on one side of the mesh belt connector assembly. The other cylindrical shaft of the mesh belt connector assembly is connected to a loop in the brake band. The main function of the mesh belt connector is to connect the mesh assembly to the brake band, ensuring that when the mesh assembly moves forward due to an aircraft impact, it can drag the brake band, causing the energy absorber assembly to activate and generate a corresponding arresting torque to stop the aircraft.

[0050] After entering the energy absorber assembly's tunnel, the brake band is guided by the guide roller assembly, changing from a horizontal to a vertical orientation, and from horizontal to the same height as the brake band disc of the energy absorber assembly. It then wraps around the brake band disc and is secured by the pressure roller assembly to prevent slippage. The primary function of the brake band is to ensure the smooth transfer of energy.

[0051] The guide wheel assembly is fixed inside the energy absorber assembly tunnel by pre-embedded bolts. The main function of the guide wheel assembly is to change the direction of the force transmitted by the brake band, so as to achieve the purpose of energy absorption by the energy absorber assembly.

[0052] The energy absorber assembly is fixed inside the energy absorber assembly tunnel by pre-embedded bolts. The energy absorber assembly is the core component of the aircraft arresting net equipment, and its main function is to generate arresting torque to stop the aircraft.

[0053] The pressure roller assembly is fixed inside the energy absorber assembly tunnel by pre-embedded bolts.

[0054] When the aircraft hits the net, the brake band moves forward with the net assembly and the aircraft, disengaging from the brake band disc of the energy absorber assembly. The brake band is then retrieved using a band retraction mechanism.

[0055] The belt winding mechanism is fixed inside the energy absorber assembly tunnel by pre-embedded bolts.

[0056] The energy absorber assembly tunnel is equipped with an H-shaped steel frame cover. The main function of the energy absorber assembly tunnel cover is to keep it flush with the surrounding ground, ensuring the smooth passage of vehicles, aircraft, etc. The energy absorber assembly tunnel cover is provided with working windows for the energy absorber assembly, used for simple routine maintenance and repairs, as well as for retraction and loading operations.

[0057] The winding mechanism and the upright frame assembly both use motors as power sources, and their power lines are connected to the electrical control box assembly's tunnel through underground pipelines.

[0058] The electrical control box assembly is fixed inside the electrical control box assembly tunnel using pre-embedded bolts. An H-shaped steel frame cover is installed on the upper part of the electrical control box assembly tunnel. The main function of the cover is to maintain flush with the surrounding ground, ensuring smooth passage for vehicles, aircraft, etc. The cover has a working window for the electrical control box assembly, used for simple routine maintenance and control operations.

[0059] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any modifications or substitutions made by those skilled in the art within the scope of the technology disclosed in this application should be covered within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
