Combined high-performance pentamaran ship with rotating body

Abstract

The invention is complex high performance quintuple body ship with a rotative object. Its feature is that the rotative accessories which rotate around the axis perpendicular to the longitudinal section of the middle of the ship are installed under the bow of central body and behind the two propulsion device at the tail by support stand. The shafts of the three accessories all linked with energy converting device. It solves the problem that twin-hull ship (boat) or small (or middle sized) twin-hull boat is limited by the large torque both longitudinally and transversely which rationally reduced the weight of the structure above the waterline base on the premise that no speed, wave tolerance, sailing adaption and intensity loss. At the same time the inventions makes use of the energy from the wave at the bow and recycle the energy of the wake from the propulsion device to supply the light, canal, emergency equipment and other subordinate aspects to save the energy.

Description

technical field [0001] The invention belongs to a high-performance new ship type, in particular to a composite high-performance pentamaran with a rotating body. Background technique: [0002] The wave piercing catamaran (boat) is a high-speed ship developed in the 1980s with excellent comprehensive technical and economic indicators, and is a recognized excellent ocean catamaran. It combines the concepts of catamaran and small waterplane design. The hull adopts a deep V-shaped line, and the sharp ribs at the head can sail through waves at high speeds; the upper main hull is also sharp-ribbed, and the lower part is V-shaped. , the distance between the deck and the waterline is large. Because of its special deep V-shaped line, the wave resistance is small, and the heave and pitch of the ship are small when sailing against waves. It has both high speed and good seakeeping performance, and it has been developing towards large-scale. In recent years, someone installed a semi-sub...

Problems solved by technology

[0005] Chinese patent: "a ship that can eliminate water resistance", publication number 168848; its main technical feature is "support the ship body with a rotatable buoy system, use the rotation of the buoy system to eliminate the water resistance of the ship, and realize Using water resistance to propel ships", the rotatable buoyancy system provided by this patent can theoretically reduce certain navigation resistance within a certain speed range, but at the same time as a propeller, its efficiency is very low; another Chinese patent: "A method for reducing ship wave-making resistance", publication number 1090542, the main technical feature is "install a water absorbing device at the bow, and make the water flow backward along the ship's side to reduce the water pressure at the bow and the additional friction caused thereby resistance, which can effectively reduce wave-making resistance and increase ship speed

", this patent installs an additional water-absorbing device at the bow of the ship to reduce the wave-making intensity of the bow, but its own power will also bring additional resistance, and the overall economy is not good.
