Recently, the British ship engineering design company BMT officially released the relevant conceptual design plan of the new generation five-body unmanned surface boat "Pentamaran" project.
The new unmanned surface boat is arranged on both sides of the central hull, and two pieces are arranged in front of each other, so that when the unmanned surface boat is driving on a flat surface, the front piece leaves the surface, and Compared to the hull, the resistance is reduced because the volume in the submerged water is reduced. When driving in waves, the sheet body can increase lateral stability.
The design of the five-hull ship aims to reduce the drag as much as possible. Tests have shown that the drag is significantly reduced compared to the traditional hulls such as single, double and triple hulls.
Unmanned surface craft is an unmanned surface craft, mainly used to carry out dangerous and unsuitable tasks for manned vessels, and can be widely used in marine transportation, marine environmental investigation, marine resource detection, marine archaeology, marine search and rescue, intelligence Collection, maritime training and testing, reconnaissance and evidence collection, security patrol, fire fighting, ship escort, anti-mine and anti-submarine tasks.
In the continuous upgrading of high-tech equipment, new materials often play an important role. Corrosion of the marine environment, high pressure, and the strong shear action brought by the undercurrent flow of the water have strict requirements on the corrosion resistance, strength and fatigue performance of the material. Carbon fiber composite materials have excellent skin resistance and corrosion resistance, and they have an advantage in the development and expansion of the marine field. In recent years, the application in the marine field has become more and more extensive.
Chinese companies have already deployed carbon fiber products for marine engineering. Among them, JSHS Carbon Fiber Technology Group announced on April 3 that its carbon fiber, warp knitted fabric, resin and other products have successfully passed the DNV · GL classification society product certification, and said that it is the first carbon fiber and its composite in China Materials companies have laid the foundation for their entry into the marine market.
