Abstract

The present invention relates to a high-speed target ship having a hybrid structure including an aluminum composite and a manufacturing method thereof. The target ship operated as a guided missile or a gun fire target on the sea is required to be sped up according to the high-speed of a trap, and is required to be easily repaired by minimizing damage in the case of being attacked by the guided missile or a gun fire. Moreover, the target ship is required to have a wide surface area to correspond to a target object ship and is required to have excellent damage stability to prevent major equipment, such as an engine or the like, from being flooded even if the hull is flooded over half due to the attack. To achieve this, the target ship is formed by covering a catamaran type hull composed of an aluminum truss structure and a fiber reinforced plastics (FRP) body with an infrared demonstration panel.

Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a high-

The target line, which is operated as a missile or shooter target, has maneuverability, large surface area and Infrared Target Strength that can be matched to the target ship. Even if the hull is hit by half or more, There is a demand for an excellent damage resilience-related technique.

   The present invention relates to a construction and a manufacturing method of a high-speed target line device capable of satisfying the technical field.

As the speed of the ship is increased, the target line must also be accelerated, and the damage to the target line due to missile shooting or shooting should be minimized, so repair and maintenance should be easy. Also, it should have a large surface area that can correspond to the target ship. Even if the hull is submerged by half, the main equipment such as engine should have excellent damage resilience that can survive without flooding.

In order to achieve a high speed of more than 40 knots, the target line should have good interwave ability to travel at high speed even in the sea condition 3 or more, which is excellent in high speed resistance characteristic. For this purpose, a preliminary analysis of hull resistance, lashing resistance and steering performance for a high speed catamaran with a cylindrical body should be devised.

In addition, a hull structure that can withstand slamming and porpoising occurring at high speeds should be implemented. For this purpose, structural stability analysis techniques for high speed catamaran hulls hybridized with aluminum truss structure and cylindrical FRP composite body should be solved.

   In the present invention, an aluminum truss structure is connected between the body and the body to reduce the weight required for maintaining excellent high-speed resistance characteristics of the target line. In order to achieve excellent damage stability even if the hull is submerged by half, Respectively.

   The stern body and the center body are made of a cylindrical FRP composite shell with a filament method and a donut type styrofoam is put in the outer shell, and a polyurethane foam is filled therebetween. The stern body is lightweight and has excellent wave resistance and structural stability. The trunk body is made of FRP composite of fine linear shape that can reduce the bow wave and is made of polyurethane foam filled in between the styrofoam, so that it is lightweight and can withstand slumping and popping by waves

Since the target line, which has been developed in large numbers and is operated as a guided missile or a combat target, is towed in the form of a towed ship, there is a limit to the speed of towing, There is a drawback that it takes time.

The present invention relates to a construction and a manufacturing method of an aluminum composite hybrid high-speed target line device in which an infrared simulating panel is mounted on a catamaran hull composed of an aluminum truss structure and an FRP composite body, It has wide infrared surface area and excellent damage resilience which can be used, so that it is possible to carry out effective test using high speed target line device with diversity of target line operation.
