Description

  The present invention relates to a bulletproof structure and a bulletproof method for a ship that protects crew members from flying bullets and shells.

  In order to protect the crew from flying bullets, shells, etc., in order to protect the crew, it is necessary to increase the thickness of the hull structural material, use an armored structural plate, and install a bulletproof plate on the hull structural material. By doing so, they were defending against flying bullets. In the exposed part of the ship, there are methods such as temporary provision of various shields and sandbags, but this is a burdensome task for the crew.

  Also, in the event of an emergency, when the structural members such as the side walls of the ship are made bulletproof as a matter of emergency, the bulletproof is placed on the back side of the structural member K in the expected direction of the bullet D as shown in FIG. Corresponding was achieved by fixing the plate 01 with bolts or adhesive tape.

  In the case of this bulletproof structure, almost all of the flight energy absorption of the bullet D relies on the shearing force of the material in the vicinity where the bullet D collides. There was a problem that the thickness had to be increased and the weight increased.

For example, conventionally, a multilayered armor structure in which panels of synthetic fibers, truss core members, etc. are laminated on titanium alloy has been proposed (see, for example, Patent Document 1), and a bulletproof stand for protecting people from bullets ( For example, see Patent Document 2), but no proposal for a bulletproof structure of a ship was found.
