The arresting cable is connected. When the aircraft lands, lower the arresting hook to hook it on the arresting cable, and the arresting cable drives the plunger inside the arresting aircraft to move, so that the fluid in the hydraulic cylinder flows to the storage tank, thereby consuming the kinetic energy of the aircraft when it lands. , generally stop after taxiing 50 meters to 95 meters, and realize the landing of the aircraft. For smaller and lighter carrier-based UAVs, such complex interception procedures can no longer meet many of the needs of military operations.

Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the accompanying drawings and an example of reliability analysis of an actual software system. In the present invention, unless otherwise expressly specified or limited, the term "installation" and other terms should be understood in a broad sense, for example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a linear connection, or a Through the introduction of the intermediate medium, it can be the internal communication of the two components.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the actual situation.

As shown in Figure 1, a rotary type carrier-based UAV arresting and recovery device includes a circular platform 2 for landing of a carrier-based UAV 13, a skyhook arresting system T and a ground arresting device D; the skyhook arresting system T includes skyhook boom 8, skyhook bracket 12, skyhook rope 7 and reinforcement mechanism 11; skyhook bracket 12 is installed at the center of circular platform 2, and a horizontal skyhook boom is installed on the top of skyhook bracket 12 8. A reinforcement mechanism 11 is installed obliquely on the top of the skyhook boom 8 and the skyhook bracket 12. Due to the triangular stable structure, the entire skyhook system can be more stable to carry longitudinal loads.

A skyhook bracket 12 is arranged in the center of the circular platform 2, and a reinforcement mechanism 11 is arranged on the upper part of the skyhook bracket 12 to assist the longitudinal bearing of the skyhook jib 8. After determining the wingspan of the ship-borne UAV 13, it is calculated at A first pulley 9 and a second pulley 10 are arranged above a suitable position, so that the carrier-based drone 13 can easily hook the rope hanging from the pulley. Wherein, the first pulley 9 and the second pulley 10 are connected with the skyhook rope 7 respectively. Recovery devices are symmetrically arranged on both sides of the skyhook support 12 , and the recovery devices respectively include a skyhook arresting system T and a ground arresting device D that are used in conjunction with each other. The ground arresting device D includes braking devices 3 symmetrically arranged on both sides of the landing area of the carrier-based UAV 13 , and the two braking devices 3 are connected by arresting cables 4 .

As shown in Figure 2-3, the skyhook bracket 12 in the skyhook system T can be retracted after use, saving space on the aircraft carrier.

As shown in FIG. 4 , the buffer 14 is installed under the circular platform 2 , which is located at the projection of the skyhook boom 8 on the circular platform 2 . The buffer 14 is a hydraulic buffer. A general hydraulic buffer is mainly composed of a cylinder barrel, an ejector rod, a piston, a return spring and a hydraulic cylinder cover. The return spring of the hydraulic buffer is connected between the piston and the bottom of the cylinder barrel. The other end of the ejector rod is rotatably connected with a buffer pulley. An entrance and exit of the skyhook rope 7 is opened on the chassis, and a buffer follower wheel is arranged outside the chassis. One end of the arresting cable 4 is wound on the reel, and the other end of the skyhook rope 7 bypasses the buffer pulleys on each hydraulic buffer in turn. The entrance and exit of the arresting cable extend to the outside of the chassis. When the recovery process starts, the carrier-based UAV 13 hooks the skyhook rope 7 to stretch the skyhook rope 7, and the buffer 14 can tighten the skyhook rope 7 at this time to limit the wing of the ship-borne UAV 13 displacement.

As shown in FIG. 5-6 , a wing characteristic groove 6 is provided in the middle of the wing of the carrier-based UAV 13 to facilitate it to hang the skyhook rope 7 so as to limit the position of the carrier-based UAV 13 .

The position of the arresting hook 5 needs to be designed according to different types of carrier-based UAV 13, and is generally installed at the tail of the carrier-based UAV 13, as shown in Figure 7-8. Before the recovery stage begins, the various mechanisms of the brake device 3 are in In the clamped state, when the arresting hook 5 hooks the arresting cable 4, a small section of the arresting cable 4 is pulled out from the disc 3-4, and the hydraulic cylinder connected to the first connecting rod 3-1 starts to work, giving it a reaction force Drive the first connecting rod 3-1, the second connecting rod 3-2, and the third connecting rod 3-3 to clamp the disc 3-4 around which the arresting cable 4 is wound, so the arresting cable 4 is limited and only elongated A small section to buffer the kinetic energy of a small part of the heading of the carrier-based UAV 13.

As shown in Figure 9, the area of the circular platform 2 is embedded on the surface deck 1 of the aircraft carrier and is flush with the surface deck 1 of the aircraft carrier, which does not affect the completion of other tasks of the aircraft carrier. Its installation schematic diagram is shown in Figure 9.

A slide rail 15 , a sliding block 16 , a shaft 17 , a bearing 18 and a fastening nut 19 are installed under the circular platform 2 to assist the rotation of the circular platform 2 . The sliding rail 15 and the sliding block 16 are installed under the circular platform 2 . The slide rail 15 is in the shape of a ring, the slider 16 is in the shape of a fan-shaped ring, the middle of the slider 16 is hollow, and is installed above the slide rail 15 through special features. The auxiliary circular platform 2 rotates. The shaft 17 is fixedly installed at the lower part of the center of the circular platform 2 to drive the circular platform 2 to rotate; when the circular platform 2 rotates, the slide rail 15 rotates accordingly. The inner ring of the bearing 18 and the shaft 17 use a tight fit, and the tightening nut 19 is used to lock the shaft 17 and the bearing 18 .

Working process: The circular platform 2 is embedded in the ship surface, and the skyhook arresting system T and the ground arresting device D are placed at a certain distance from the center of the circular platform 2. When the carrier-based UAV 13 lands in the area of the circular platform 2, the The arresting hook 5 at the rear of the body hooks the arresting cable 4 of the ground arresting device D, and the arresting cable 4 is only pulled out to a limited length because its braking mechanism limits the arresting cable 4. At this time, the kinetic energy of the engine of the shipborne UAV 13 is buffered for a A small part, therefore, the carrier-based UAV 13 continues to slide along the tangential direction of the platform, its wing feature groove 6 hangs on the skyhook rope 7, and its wing is also limited, so the aircraft drives the circular platform 2 to rotate, Most of the remaining kinetic energy of the engine is consumed by the frictional force when the circular platform 2 rotates. When the carrier-based UAV 13 deviates, the arresting system composed of the skyhook arresting system T and the ground arresting device D can ensure that the arresting hook 5 is higher than the ground arresting cable 4 when the carrier-based UAV 13 is eccentrically attached or landed At least one side of the wing feature groove 6 can hang the skyhook rope 7, so that the drone can be recovered smoothly and the success rate of interception can be improved. The circular platform 2 can recover the carrier-based UAV 13 from any angle of the aircraft carrier, and multiple UAVs can be recovered from different directions by arranging multiple ones on the aircraft carrier, thereby improving the recovery efficiency of the carrier-based UAV 13 recovery process.
