Description

Drog System The present disclosure relates to a drogue system applied to an unmanned submersible. Submarines used horizontal launch tubes or installed external hooks to launch and recover Unmanned Underwater Vehicles (UUVs). In the method using horizontal launch tubes, UUVs were launched and recovered from the horizontal launch tubes, and after the operation was completed, the submarine met with the UUV at a predetermined time to recover it. In the method using external hooks, a hook was installed on the exterior of the submarine, and UUVs were launched and recovered from the external hook. These conventional methods generally recovered UUVs while the submarine was completely stationary. This was because interaction with the UUV becomes difficult when the submarine is moving at high speeds, and the risk of damage or accidents increases during the launch and recovery process. In particular, when using an external hook device, the submarine must move near the surface and then slow down or come to a complete stop to launch and recover the UUV. This has the disadvantage of reducing the submarine's stealth capabilities. Conventional methods for launching and recovering UUVs from submarines have limitations in terms of efficiency and safety. Therefore, there is a need to develop technology that can safely launch and recover UUVs even while the submarine is operating underwater without moving near the surface or stopping. Figure 1 is a drawing showing an unmanned submersible and a submarine that launches or recovers the unmanned submersible. FIG. 2 is a drawing showing an unmanned submersible equipped with a drogue system according to the present disclosure. Figure 3 is an enlarged view of the drag system in Figure 2. Figure 4 is a drawing showing a front cross-section of the drogue system in Figure 2. Figure 5 is a drawing showing an enlarged view of the drag in Figure 2. The present disclosure is described in detail below with reference to the attached drawings. However, this is merely an example and is not limited to the specific embodiments illustratively described in the present disclosure. Referring to FIGS. 1 and 2, the drogue system (100) according to the present disclosure may be installed on an unmanned submersible (20) to enable the unmanned submersible (20) to be launched or recovered by the submarine (10). The unmanned submersible (10) (Unmanned Underwater Vehicle, UUV) may be launched or recovered by the drogue system (100) while moving underwater. Referring to FIG. 3, the drag system (100) can be configured to include a case (110), a drag (120), and a winch (130). The case (110) can be installed in the unmanned submersible (20). The case (110) can be installed inside the unmanned submersible (20). Additionally, the case (110) can form the hull of the unmanned submersible (20). When the case (110) forms the hull of the unmanned submersible (20), the case (110) can be configured in the middle part of the unmanned submersible (20), as shown in FIG. 2. Components including a drag (120) and a winch (130) can be housed and installed inside the case (110). The winch unit (130) is installed in the case (110) and can control the position of the drag (120). The winch unit (130) can be configured to include a cable (131), a roller unit (132), and a driving device (140). The cable (131) is connected to the drag (120), and the cable (131) can be wound to retrieve the drag (120) into the case (110), or the cable (131) can be unwound to withdraw the drag (120) from the case (110). The drive unit (140) can move the drag (120) by winding or unwinding the cable (131). The roller section (132) is configured to include a driving roller (1321) and a support roller (1322) to wind or support the cable (131). The drive roller (1321) is connected to the drive device (140) so that the cable (131) can be wound or unwound by the drive of the drive device (140). The support roller (1322) can be positioned between the drive roller (1321) and the drag (120) to support the cable (131) when the cable (1321) is wound or unwound by the drive roller (1321). A drive roller (1321) is installed on the drive device (140), and a cable (131) can be wound or unwound on the drive roller (1321) by the drive of the drive device (140). At this time, a support roller (1322) may be positioned in front of the drive device (140), and the cable (131) may be connected to the drag (120) while being supported by the support roller (1322). When the drive roller (1321) rotates by the drive of the drive device (140), the support roller (1322) may also rotate in the same direction while supporting the cable (131). The drive unit (140) can wind or unwind the cable (131) by using a motor to transmit rotational force to the drive roller (1321). At this time, an encoder (133) for measuring the rotational direction or rotational speed of the driving device (140) may be installed on the support roller (1322). By measuring the rotational direction or rotational sp
