Description

Technical Field

[0001] The component structure of the towed linear array of the present invention, in particular, is a tail assembly of the towed linear array used for artificial mounting and recovery. Background Art

[0002] A towed linear array is generally composed of a linear array and a tail assembly. The tail assembly provides resistance to keep the array section in a horizontal posture when the towed linear array is sailing. Usually, the towed linear array is designed for the neutral density of seawater, and the density of the tail assembly is the neutral density of seawater or greater than the density of seawater. Generally, a winch is required to retract and release the towed linear array, and the tail assembly structure informs the winch that it has been recovered. For towed linear arrays that do not rely on the platform's own winch recovery and are installed on the aircraft in a mounting manner, the specific position of the towed linear array needs to be located for manual recovery.

[0003] The towed array is connected to the tail of the aircraft through a tow cable. The length of the tow cable is generally several hundred to more than one thousand meters depending on different needs. The total length of the tow cable and the tow array can reach one kilometer. Aircraft with winches can use the winch to recover the tow cable and the tow array. For some aircraft without winches for economic reasons, the tow cable and the tow array need to be recovered manually. In actual operation, aircraft without winches need to recover the tow array and the tow cable separately because the total length of the tow cable and the tow array is too long. Summary of the invention

[0004] The present invention aims to solve the above-mentioned shortcomings of the prior art and provide a tail assembly of a towed linear array for manual mounting and recovery that is easy to find and recover.

[0005] The present invention solves its technical problems by adopting a technical solution: the tail component of the towed array for artificial mounting and recovery includes a strong rope, a rope threading plug, and a buoyancy block. One end of the strong rope is fixed to the rope threading plug, the guide shell is fixed to the rope threading plug by screws, the rope threading plug is connected to the tail of the towed array, and one or more buoyancy blocks are fixed to the strong rope.

[0006] The buoyancy block is provided with a fixing hole, and the buoyancy block is connected in series to the strong rope through the fixing hole.

[0007] The fixing hole is filled with mold glue.

[0008] Positioning rings are arranged on the strong ropes at the front and rear of the buoyancy block.

[0009] The tail end of the strong rope is provided with an LED lamp, and the number of the LED lamps is one or more.

[0010] A wireless beacon is arranged in the rope threading plug.

[0011] The buoyancy block is of streamlined design.

[0012] The beneficial effects of the present invention are: the present invention has a simple structure and an overall positive buoyancy design. When the aircraft is sailing, it sinks with the towing force, can provide resistance to play a role in rectification and maintaining the horizontal stability of the towed array. When the aircraft stops sailing, it can float to the surface, which is convenient for positioning, salvage and recovery of the towed array. The design of wireless beacons and LED lights further enhances the positioning function, making it convenient for staff to find and salvage. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below in conjunction with the accompanying drawings:

[0018] As shown in the figure, the tail assembly of the towed array for manual mounting and recovery includes a strong rope 1, a rope plug 3, and a buoyancy block 4. One end of the strong rope 1 is fixed to the rope plug 3 by weaving or other means. The guide shell 2 is fixed to the rope plug 3 by screws to protect the connection of the strong rope 1. The rope plug 3 is connected to the tail of the towed array to realize the connection between the tail assembly and the array section. One or more buoyancy blocks 4 are fixed on the strong rope 1. The buoyancy block 4 is streamlined to reduce underwater noise. A fixing hole 8 is provided on the buoyancy block 4. The buoyancy block 4 is connected in series to the strong rope 1 through the fixing hole 8. The buoyancy block 4 is fixed to the strong rope 1 through the strong rope fiber. A positioning ring 5 is provided on the strong rope 1 in front and behind the buoyancy block 4. After the buoyancy block is fixed to the strong rope, the fixing hole 8 can be filled with glue using a related mold to further ensure the streamline of the buoyancy block. A wireless beacon 7 is provided in the rope plug 3. The tail end of the strong rope 1 is provided with an LED lamp 6, which is fixed to the strong rope 1 by braiding strong rope fibers. The number of the LED lamp 6 is one or more.

[0019] The tail assembly uses strong ropes 1 of different lengths and different numbers of buoyancy blocks 4 according to different density requirements and lengths. The buoyancy blocks 4 use a floating material with a certain strength, and the strong rope 1 provides a certain breaking force to enhance the service life of the tail assembly. The LED light 6 and the wireless beacon 7 can be installed as needed to further enhance the positioning function. If the tail assembly no longer needs the LED light 6 or the wireless beacon 7 after installation, the tail assembly can also quickly and conveniently disassemble the LED light 6 and the wireless beacon 7.

[0020] The wireless beacon 7 and the LED lamp 6 are installed on the rest of the tail assembly, or the wireless beacon 7 is made into a separate structural component and installed on the strong rope of the tail assembly. The LED lamp 6 can be replaced by multiple lamp components installed on the tail assembly. The buoyancy block 4 is made into a streamlined shape with different shapes or different lengths. The buoyancy block 4 can be fixed to the rope only by the locating rings at both ends or other means without a positioning hole.

[0021] The present invention is a towed linear array for manual mounting and recovery. The towed linear array is connected to the tail of the aircraft through a tow cable, and the total length can reach one kilometer. The towed linear array for manual mounting and recovery does not rely on the platform's own winch for recovery, but is mounted on the aircraft. During recovery, the towed linear array and the tow cable need to be recovered manually and separately. The present invention provides a positioning function, which locates the specific position for easy manual recovery. The present invention is a positive buoyancy design, which sinks with the towing force when the aircraft is sailing, and can provide resistance to play a role in rectifying and maintaining the horizontal stability of the towed linear array. When the aircraft stops sailing, it can float to the surface, which is convenient for positioning, salvaging and recovering the towed linear array. The present invention has a simple structure and a certain strength, and the fixation of the buoyancy block has double protection. In extreme cases during use, the destruction of a single or several buoyancy blocks will not affect the overall performance of the tail assembly.

[0022] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
