Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air drop, in particular to an air drop tray system for carrying multiple weapon nodes by using a grid frame. BACKGROUND

[0002] Airborne operation has become a key field of military construction in the world. Airborne operation refers to a military operation of dropping troops, supplies, equipment, etc. into a predetermined area by transport aircraft or helicopters.

[0003] Considering that transport aircraft have incomparable load capacity compared to other aircraft, the US Air Force Research Laboratory developed a new air drop weapon system named Rapid Dragon System, and completed the first air drop test in 2021, verifying the feasibility of the system. The core idea of this system is to fully utilize the air drop capacity of transport aircraft, transforming traditional transport aircraft into a platform for dropping long-range precision strike weapons, so as to realize rapid and large-scale deployment of long-range weapons such as cruise missiles and air drop torpedoes.

[0004] At present, the main tasks of China's large transport aircraft are still concentrated in the fields of supply delivery and troop deployment, and the expansion of long-range strike task types has not been realized. The main reason is the lack of a scientific and reasonable air drop tray system, which makes it difficult to implement flexible loading and air release of weapon nodes. The working process of large transport aircraft combined with air drop tray system is as follows: when the aircraft arrives at the target airspace, multiple air drop tray systems are pulled out from the tail cabin and swung to a stable falling state under the action of a tow parachute, and relevant procedures are executed to release the weapon nodes in the air in turn.

[0005] For long-range rapid strike tasks in specific areas, China usually uses anti-submarine patrol aircraft, bombers, attack aircraft, etc. to complete the task by external hanging weapons. Compared with the above-mentioned aircraft striking by external hanging weapons, the striking method of large transport aircraft combined with air drop tray system is completely different. Instead of placing each weapon node on a separate rack, all nodes are loaded in an air drop tray system. This particularity requires that the air drop tray system design must consider two key issues. First, to improve the spatial adaptability of the air drop tray system to different transport aircraft models, the air drop tray system must have unitized features, which can be easily disassembled and assembled, and can be flexibly loaded by controlling the number of nodes. Second, to ensure the precision, order and accuracy of the release process of multiple weapon nodes, air control devices and emergency handling devices must be provided.

[0006] In the field of aerospace, weapon node locking release devices mainly include pyrotechnic locking release, electric drive locking release, magnetic drive locking release, gas drive locking release and thermal drive locking release, etc. Each type of locking release mechanism has been widely used, and each has its own advantages. For the locking release of weapons mounted outside the aircraft, only the driving type suitable for the characteristics of the suspension and the aircraft needs to be considered. For the air drop tray system, in order to avoid release failure caused by differences in the air environment, thereby affecting the achievement of the mission target, it should be equipped with a multi-mode release program.

[0007] The development of the air drop tray system realizes the order-of-magnitude growth of the number of weapon nodes carried, opens up a new direction for the mission type of large transport aircraft, and also marks a historic improvement in air long-range strike capability. China has a variety of large transport aircraft models that reach the world's advanced level, but the supporting air drop tray system is still in the technical blank stage.

[0008] Therefore, for large transport aircraft, it is urgent to develop a unitized, self-controlled, intelligent, and highly reliable multi-weapon node air drop tray system at the present stage. SUMMARY

[0009] The purpose of the present application is to provide a grid type air drop tray system suitable for transport aircraft, which can effectively utilize the cabin space of the transport aircraft and realize the deployment of multiple weapon nodes.

[0019] As preferred, the control logic of the tray posture capture and timing judgment program is: real-time receiving of the posture / position sensor signals of the two end marker points of the tray since the tray system is towed away from the plane; judging whether the tray system enters a stable falling state based on the sensor signals, and the time node of entering the stable falling stage; once the stability is judged, the node release control program is triggered. The node release control program is responsible for controlling the electromagnetic release mechanism to release the weapon nodes in sequence.

[0020] As preferred, the node release control program is responsible for controlling the electromagnetic release mechanism to release the weapon nodes in sequence, that is, driving the electromagnetic release mechanism in each cell in sequence: driving the clamp to lose magnetism, pulling the clamp to overturn by the transmission piston rod, releasing the weapon node, and returning the release result to the industrial computer system; if an unexpected failure occurs and the weapon node cannot be normally released, the pyrotechnic release mechanism is started to drive the explosion bolt to complete the release of the weapon node.

[0021] The present application marks the point posture / position sensor signal through an industrial computer system, captures the aerial posture of the air-drop pallet and judges it. Once the air-drop pallet posture meets the stable falling condition, the industrial computer system drives the electromagnetic release mechanism, the calipers are demagnetized and turned over, and the weapon nodes are sequentially dropped into the predetermined area to complete the military attack.

DETAILED DESCRIPTION

[0040] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings:

[0041] Example 1

[0042] This embodiment discloses a grid-type multi-weapon node airdrop tray system, including a multi-weapon node 1, a grid-type airdrop tray frame 2, an industrial computer system 3, and a plurality of marker point posture / position sensors 4-11.

[0043] Among them, the grid-type airdrop tray frame 2 includes a number of grid-type frame cells 12 that can be split according to the number of nodes. The weapon node 1 is fixed in the frame cell 12 before being dropped, and adjacent cells are fixedly connected by bolts.

[0044] The industrial computer system 3 completes the pallet posture capture, delivery timing determination, and node safety release based on multiple marker point posture / position sensors 4 to 11, and controls each framework cell to realize the delivery of multiple weapon nodes 1.

[0045] Specifically,

[0046] The airdrop pallet frame can be split into multiple frame cells based on the number of weapon nodes. The cell size can be customized according to the weapon size and can be spliced ​​to fit different transport cabin spaces.

[0047] like Figures 2-7 As shown, in this embodiment, the grid-type airdrop tray can carry nine weapon nodes, and the overall structure is divided into nine cells according to the nodes. Each cell comprises a weapon node 1, an airdrop tray frame 2, an industrial computer system 3, and eight marker position / attitude sensors: A1 marker sensor 4, A2 marker sensor 5, A3 marker sensor 6, A4 marker sensor 7, B1 marker sensor 8, B2 marker sensor 9, B3 marker sensor 10, and B4 marker sensor 11. Furthermore, the airdrop tray frame 2 is composed of nine airdrop tray frame cells 12 connected together. Each airdrop tray frame cell 12 contains four calipers 13, a transmission piston rod 14, an explosive bolt 15, a nut 16, a caliper slide 17, and a transmission cylinder 18.

[0048] Specifically,

[0049] The caliper 13 is hinged to the side wall of the frame cell 12 through the caliper slide rod 17, and the upper end of the caliper 13 is connected with the ball head of the transmission piston rod 14. The two ends are fixed on the frame through the explosive bolt 15 and the nut 16. The caliper is made of a combination of electromagnet and coil, which not only has a physical clamping effect, but also has an adsorption effect on the node after being energized. In the embodiment, two groups of orthogonal calipers are arranged, which are arranged at the upper and lower ends of the inner wall of the frame cell 12. After the weapon node is carried, the two pairs of calipers are flat and closed, the inside of the caliper is energized to form a magnetic field, and the weapon node is adsorbed to constrain the upper and lower ends of the weapon node respectively. The front end of the transmission piston rod 14 is connected with the bottom execution point of the caliper through the universal joint, and the rear end of the piston head is nested in the transmission cylinder 18. After receiving the electromagnetic drive signal, the piston rod is linearly contracted in the cylinder, which converts the linear motion into the rotary motion of the caliper around the slide rod. The explosive bolt 15 penetrates the caliper base and the frame mounting hole, and is locked and fixed by the nut 16 at both ends. The explosive bolt 15 bears the working load of the caliper in the normal state, and is broken after receiving the pyrotechnic signal in the emergency state, so as to release the connection between the caliper and the frame, realize the whole caliper to separate, and prevent the failure of the caliper overturning mechanism and avoid the safety accident contrary to the task target.

[0050] For a single-shot weapon node, the structure schematic diagram of the weapon node carried on the air drop tray is as shown in Figures 5-7 At this time, the industrial computer system 10 supplies power to the electromagnetic release mechanism, the caliper 13 made of electromagnet material forms a strong adsorption force on the weapon node 1, the transmission piston rod 14 is completely stretched out in the transmission cylinder 18, the caliper 13 is in a horizontal clamping state, and the two groups of calipers 13 fix the upper and lower ends of the weapon node in a normal way.

[0051] In the normal release state, the industrial computer system (3) controls the electromagnetic release mechanism, cuts off the power supply of the caliper 13, makes the electromagnetic adsorption force disappear, drives the electromagnetic valve in the transmission cylinder 18 to open at the same time, and makes the piston rod 14 contract under the hydraulic drive. The caliper rotates around the slide rod and is retracted. At this time, the weapon node is released and freely falls.

[0052] In the emergency release state, the sensor detects that the piston rod displacement is abnormal. At this time, the pyrotechnic circuit is triggered, the explosive charge in the explosive bolt 15 is detonated, the caliper 13 is separated from the frame as a whole, and the weapon node is freely separated and falls by gravity.

[0053] For the grid type air drop tray in the full load state of the node, the overall structure schematic diagram is as shown in Figure 2 and Figure 3As shown. At this time, 9 weapons nodes are all carried and fixed, and the parachute system is assembled at the tail of the air drop tray, and then pushed into the transport cabin. According to the space of the transport cabin, a proper number of air drop trays are pushed in, and then the plane takes off and reaches the target airspace. Then, according to the standard operation of heavy air drop, each air drop tray is air dropped. After leaving the plane, the air drop tray operation such as drop timing judgment, release structure actuation, mode switching processing is completed by the industrial computer system 3. As shown Figure 8 As shown, the industrial computer system 3 mainly includes two embedded programs inside, which are the cargo platform posture capture and timing judgment program and the node drop control program. It should be noted that for the frame cells of the air drop tray, the size will be customized according to the size of the weapon node. Each frame cell maintains a square design, which is conducive to the connection between the cells to form a complete air drop tray system. In addition, the 9-node air drop tray system shown in the present application is only an example, and the grid cell design aims to adjust the number of weapon nodes carried according to the cabin size, thereby enhancing the adaptability of the air drop tray system to different aircraft models.

[0054] According to the task requirements, cruise navigation or air dropped torpedo weapon nodes are loaded on the air drop tray. After multiple air drop trays are loaded into the transport plane, the plane takes off and reaches the target airspace, and the tow parachute at the tail of the air drop tray is released. Under the action of the fully opened tow parachute, each air drop tray leaves the cabin in turn and starts to swing down. When leaving the cabin, the industrial computer system equipped on the air drop tray starts to start, and the embedded tray posture capture and timing judgment program runs to receive the position / posture sensor signals of the 8 markers in real time. Based on the marker signal, when the program judges that the tray system enters the vertical stable falling stage, the embedded node drop control program will be automatically activated. In the normal mode, the node drop control program drives the electromagnetic release mechanism, and each weapon node is sequentially dropped into the predetermined area. In the emergency mode, in order to avoid unexpected situations such as release structure failure, the present application configures a pyrotechnic release method (explosive bolt 15) as an alternative, and the node drop control program drives the explosive bolt to act, and the node buckle is disconnected from the tray frame. Each weapon node is sequentially dropped. After all the weapon nodes are released, the air drop tray system stably descends under the action of the parachute until landing.

[0055] In summary, the present application realizes flexible loading and dropping of multiple weapon nodes through the grid type air drop tray system, effectively utilizes the cabin space, converts the transport plane into a long-range strike platform, and greatly improves the combat capability and strategic deterrent force.

[0056] The grid type multi-weapon node air drop tray system of the present application cooperates with the parachute system of heavy air drop, can carry long-range cruise missiles or air dropped torpedoes and other lethal weapons, and converts large transport planes from traditional material dropping platforms into long-range strike platforms, realizes rapid deployment on the battlefield at extremely low cost, and significantly enhances the strategic flexibility of the air force.

[0057] Embodiment 2

[0058] The present application discloses a method for releasing a grid multi-weapon node aerial delivery tray system.

[0059] For the industrial computer system, it is located at one side of the aerial delivery tray system, responsible for the timing determination and related driving of the tray system in the air. The industrial computer system internally embeds two major programs, respectively, the tray posture capture and timing determination program and the node release control program.

[0060] As shown in Figure 1 , the aerial working process of the aerial delivery tray of the present application is divided into four steps. Step 1, under the pulling action of the traction parachute, the node fully loaded aerial delivery tray is launched from the tail of the airplane. Step 2, after the combination of the aerial delivery tray and the traction parachute is launched, it swings and descends. Step 3, when the aerial delivery tray swings to a stable falling state, the control system is started. Step 4, each weapon node is released in turn, and the task is completed.

[0061] Based on the above platform component features, the working method of the technical scheme of the present application is as follows:

[0062] As shown in Figure 1 and Figure 8 , according to the task requirements, several grid aerial delivery tray systems are pushed into the cabin of a large transport aircraft, and each aerial delivery tray is in a fully loaded state. Then, the large transport aircraft takes off and reaches the target area, the tail hatch is opened, and the traction parachutes at the tail of each aerial delivery tray system are released in turn. Under the pulling of the traction parachute, the aerial delivery tray system is launched in turn, the corresponding parachute is pulled out and deployed, and the aerial height gradually decreases.

[0063] During this landing process, the aerial delivery tray swings, and the tray posture capture and timing determination program embedded in the industrial computer system 3 continuously runs, real-time receives the posture signals and position signals of the 8 marker point sensors, and makes timing determination. The program compares the coordinate change information of A1(x1, y1, z1) and B1(a1, b1, c1) marker points, A2(x2, y2, z2) and B2 marker points(a2, b2, c2), A3(x3, y3, z3) and B3(a3, b3, c3) marker points, and A4(x4, y4, z4) and B4(a4, b4, c4) marker points in real time. When x i =a i and z i =c i , that is, when the coordinates of the four groups of marker points at both ends of the tray remain consistent except the height, it is determined that the aerial delivery tray enters the vertical stable falling state, and the node release control program in the industrial computer system 3 is immediately activated.

[0064] The node release control program will drive the electromagnetic release mechanism in each cell to operate in sequence based on the node sequence. First, the two pairs of clamps 13 of the weapon node 1 are powered off, the magnetic field and the adsorption force disappear, and then the transmission piston rod 14 is retracted inward in the transmission cylinder 18, the clamps 13 are flipped, the restraint of the weapon node 1 disappears, and the weapon node is vertically released. Then, the rest of the weapon nodes are repeated until all the release is completed, and the air drop tray is stably descending under the deceleration of its parachute until landing.

[0065] Considering the variability of such military air drop task scenarios and the large environmental differences, to prevent the electromagnetic release mechanism from failing in a harsh environment, causing a weapon node 1 to fail to release normally and causing an unexpected safety accident. In the node release control program embedded in the industrial computer system 3, the invention configures an emergency release mode, i.e., a pyrotechnic release mechanism, for each weapon node of the air drop tray. When the electromagnetic release mechanism of a weapon node 1 fails, the industrial computer system 3 will start the alternative solution to drive the explosive bolt 15 connected to the clamp 13 and the tray frame 2 to act. After the pyrotechnic explosion, the clamp 13 loses the connection between the clamp 13 and the tray frame 2, and the weapon node 1 completes the release.

[0066] The above specific embodiments are further descriptions of the purpose, technical solutions and beneficial effects of the invention, and cannot be understood as limitations of the invention. Any modifications, improvements, equivalent replacements, etc. made within the spirit and principles of the invention shall be included in the protection scope of the invention.
