AI Technical Summary

Technical Problem

Conventional unmanned underwater vehicles (UUVs) are not suitable for deep-sea missions due to their heavy design, limited payload capacity, and inability to withstand high pressures.

Method used

A monocoque body design for UUVs made from a fiber-reinforced sheet, such as a polymer reinforced with carbon fibers, which provides structural support, allows for increased payload capacity, and is lightweight enough to handle deep-sea conditions.

Benefits of technology

The monocoque body design results in a UUV that is stronger, lighter, and capable of carrying a larger payload, enabling it to perform deeper and longer missions while maintaining structural integrity under high pressure.

Abstract

To provide an unmanned underwater vehicle having a suitable monocoque body.SOLUTION: A monocoque body 110 for an unmanned underwater vehicle ("UUV") includes a front portion 120, a tail portion 130, a body interior surface 115, and a body exterior surface 112. The monocoque body 110 may be an integral-type structure shell made by fiber reinforcement polymer. The UUV 100 may further include transverse structural members 140A and 140B. A fiber reinforced sheet is polymer reinforced by carbon fiber, and the monocoque body 110 forms a part of the UUV 100 which is free submerged type.SELECTED DRAWING: Figure 1
