Description

Technical Field

[0001] This invention relates to the field of machinery, and more specifically, to an aircraft material delivery system. Background Technology

[0002] Chalcohol strips are straight strips or fibers of metal or dielectric material coated with a thin layer of metal, typically half a wavelength in length, much larger than their diameter. Examples include aluminum foil and aluminized fiberglass. The dimensions of chalcohol strips are generally in the micrometer range; millions of strips can be packed into a very small space and suspended in the air for extended periods. When deployed in large quantities, they can generate strong radar echoes. The essence of chalcohol jamming technology is that the chalcohol strips induce alternating currents under the influence of an alternating electromagnetic field. According to electromagnetic radiation theory, these alternating currents radiate electromagnetic waves, producing secondary radiation that interferes with radar.

[0003] In the prior art, there is a passive interference device for foil strips, which mounts a column of material on a multi-layered, rotatable material tray similar to a honeycomb briquette, and uses compressed gas as power to launch the column of material. The air compressor and high-pressure gas storage device require a large amount of space and weight, and the material tray is also quite heavy.

[0004] Existing aircraft material delivery systems, such as radar jamming chaff delivery systems, are all small delivery devices with limited capacity and weight of materials. Moreover, the weight ratio of the delivery device to the material is too high, resulting in low overall structural efficiency.

[0005] The content of the background section is merely the technology known to the inventor and does not necessarily represent the prior art in this field. Summary of the Invention

[0006] To address the limitations of existing foil dispensing equipment in terms of both the volume and weight of materials it can hold, as well as the excessively high weight-to-material ratio and low overall structural efficiency, this invention provides a multi-purpose aircraft material dispensing system. Its material storage capacity can be expanded and adjusted according to the aircraft's takeoff weight and mission requirements. A single dispensing mechanism can be used for tasks with different weight requirements, significantly improving the overall system's structural efficiency.

[0034] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0035] Figure 1 An embodiment of the aircraft material delivery system provided by the present invention is shown, including a material delivery compartment 100, a first material storage compartment 200, a second material storage compartment 300, and a third material storage compartment 400. In this embodiment, as... Figure 1 As shown, the material delivery compartment 100, the first material storage compartment 200, the second material storage compartment 300 and the third material storage compartment 400 are combined into a whole by the truss 500.

[0036] In this embodiment, there are three material storage compartments. In other embodiments of the present invention, the number of material storage compartments can be arbitrary. The material storage capacity can be expanded and adjusted according to the aircraft's takeoff weight and mission requirements. A single delivery mechanism can be used for delivery missions with different weight requirements, thereby greatly improving the structural efficiency of the entire system.

[0037] In this invention, the material delivery chamber 100 includes a traction assembly and a pressure plate assembly. The traction assembly is connected to the material in the first material storage chamber 200. Under the action of the traction assembly, the material is transported from the first material storage chamber to the material delivery chamber 100, and under the action of the pressure plate assembly, the material is delivered to the outside of the material delivery chamber 100.

[0038] In this embodiment, as Figure 3 , 4 As shown, the material is encased in a long strip of thin film and arranged together to form a material column 600. In this embodiment, as... Figure 1As shown, material columns are wound in the first material storage compartment 200, the second material storage compartment 300, and the third material storage compartment 400, forming a first material roll 610, a second material roll 620, and a third material roll 630, respectively. The first material roll 610, the second material roll 620, and the third material roll 630 are connected end-to-end (i.e., the tail of the first material roll 610 is connected to the head of the second material roll 620, and the tail of the second material roll 620 is connected to the head of the third material roll 630). Figure 1 In the embodiment shown, the first material roll 610, the second material roll 620, and the third material roll 630 are connected together by connecting ropes A and B, respectively.

[0039] The materials described in this invention include one or more of the following: electronic countermeasures foil, snow melting agent, cloud and fog dispersing agent, cloud and fog generating agent, artificial rainmaking agent, seeds, and fertilizer.

[0040] In this embodiment, the traction assembly includes a traction motor (not shown), a traction wheel 111, and a traction member 112. In this embodiment, the traction member 112 is a traction belt; in other embodiments of this application, the traction member may also be a traction rope. The traction wheel 111 is connected to both the traction motor and the traction belt 112. The traction belt 112 is connected to a first material roll 610 in the first material storage chamber 200. Under the action of the traction motor and the traction wheel 111, the material is conveyed from the first material storage chamber 200 to the material delivery chamber 100.

[0041] like Figure 3 As shown, the traction belt 112 is connected to the film jacket. Under the action of the pressure plate assembly, the film jacket separates from the traction belt 112, and the film jacket is broken, allowing the material to be released outside the material delivery chamber 100. In this embodiment, the material is wrapped inside the elongated film jacket. Optionally, in other embodiments of this application, the film jacket may also be cylindrical or square, or of course, any other shape that can be connected to the traction member 112.

[0042] like Figure 1 As shown, the materials in the first material storage compartment 200, the second material storage compartment 300, and the third material storage compartment 400 are stored in rolls after being sealed with a thin film. The first and last ends of each roll are connected, and the traction wheel 111 is electrically driven by the traction motor in the material delivery compartment 100 to pull it. The central shafts 210, 310, and 410 of the first, second, and third material rolls are fixed on the truss 500. Bearings are installed on the material shafts 210, 310, and 410, allowing them to rotate freely around the center. Drive or brake motors (not shown in the figure) are installed at the ends of the material shafts 210, 310, and 410. When the material rolls 610, 620, or 630 are heavy or have a large moment of inertia, the material can be conveyed to the material delivery compartment 100 by the shaft motor, the traction motor, and the traction wheel 111.

[0043] As shown in Figures 2(a) and 2(b), in this embodiment, the pressure plate assembly includes an electric cylinder 121, a first pressure plate 122, a vertical plate 123, a cam mechanism 124, a second pressure plate 125, a cutter 126, a torsion spring 127, and a spring device 128. The first pressure plate 122 is connected to the electric cylinder 121 and the vertical plate 123, the cam mechanism 124 is connected to the vertical plate 123 and the second pressure plate 125, and the cutter 126 is located at the hatch of the material delivery chamber 100.

[0044] In this embodiment, as Figure 6 As shown, the cutting tool 126 is a grid blade. The grid blade has a sharpened surface that contacts the material. The specific form of the grid blade can be customized according to requirements.

[0045] After the material column 600 is pulled to the material delivery chamber 100 by the traction wheel 111, the material is compressed out of the delivery chamber 100 by the first pressure plate 122. The opening of the delivery chamber 100 is equipped with a grid knife 126, which is used to cut the film covering the material, so that the material can be freely dispersed. The first pressure plate 122 is controlled by the reciprocating motion of the electric cylinder 121. When the electric cylinder 121 moves downward, the upright plate 123 pushes the cam mechanism 124 on the side wall of the delivery chamber 100 (as shown in Figure 5(b)). The cam mechanism 124 compresses the second pressure plate 125. While the second pressure plate 125 presses down on the traction belt 112, the first pressure plate 122 continues to compress the material column 600 downward. The film covering is cut by the grid knife 126 installed at the opening of the delivery chamber, and the material is delivered to the outside. Figure 5(a) shows the state of the upright plate and the cam mechanism when the pressure plate is retracted.

[0046] In this embodiment, as shown in Figures 2(a) and 2(b), a torsion spring 127 (or a small motor) is installed at the center of the cam mechanism 124 for resetting the cam mechanism 124. A spring device 128 is installed at the lower part of the second pressure plate 125 for resetting the second pressure plate 125.

[0047] The material delivery system provided by this invention offers convenient material loading and unloading, employs low-voltage DC direct drive, features a simple and reliable structure, low energy consumption, and can meet the needs of various delivery tasks. The material compartment has good expandability. It can be used not only for electronic countermeasures chaff interference material delivery but also for artificial weather modification (artificial rain) material delivery, as well as for large-scale agricultural seed and fertilizer delivery. Simply package the materials to be delivered into cylindrical, strip, or small square packages according to task requirements, and match them with different types of grid blades accordingly to achieve multi-purpose material delivery. Furthermore, the equipment compartment can be installed inside the aircraft fuselage or externally mounted on the fuselage belly or under the wing, truly realizing a multi-purpose function.

[0048] The preferred embodiments of the present invention described above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention.
