Sea condition adaptive variable shape planing boat

Abstract

The invention provides a sea condition self-adaption planing boat capable of adjusting forms. The planing boat is composed of a main hull located in the middle and sheets hinged to two sides of the main hull, and the main hull and the sheets are connected through a sheet rotating deploying and retracting device. The sheets on the two sides start at 40% of the length of the boat and extend to a stern, the two sheets are independent, and the deck edges of the sheets are hinged to the main hull. The inner side shape of the sheets is completely attached to the outer side of the main hull, and folding corners are arranged on the outer side. By means of the rotating deploying and retracting device on a deck of the main hull, the sheets can be rotated and self-locked around the hinged position, so that the relative movement of the sheets and the main hull is realized. In response to the sea conditions of different wave levels, the mutual transformation between a single-hull boat form and an M-type boat form of the planing boat can be realized by rotating and deploying and retracting of the sheets, so as to improve the speedability or wave resistance of the planing boat and enhance the ability of the planing boat to complete a task.

Description

technical field [0001] The present invention relates to a ship structure, in particular to a sea condition self-adaptive variable shape planing boat, which can be realized in two types of single planing boat and M-type planing boat by rotating its two sides according to the change of sea conditions. The shape of the planing boat transforms into each other. Background technique [0002] As the earliest developed ship relying on hydrodynamic navigation, the planing boat has been widely used in military and civilian fields. Due to its gliding characteristics, the hull of a conventional single-hull planing boat rises after entering the gliding state, and the draft decreases, so that the resistance during navigation is greatly reduced. It is difficult to restore a stable navigation state, and even cause capsizing, so the seakeeping performance of the planing boat is poor, and it is difficult to work normally in many waters with harsh sea conditions or places with high sea condit...

AI Technical Summary

Problems solved by technology

However, due to the fact that the two sides of the body participate in drainage, compared with the larger wet area of ​​the single-body boat, the resistance increases. Although the speed is excellent, it is not as good as the single-body planing boat.
