Problems solved by technology

But there are also the following deficiencies: 1. It is not easy to match the front wedge-shaped plate and the tail line or wave-pressing plate (or tail wedge-shaped plate) of the boat properly, and it is difficult to achieve a better drag reduction effect; 2. The negative pressure produced by the wedge-shaped plate, It will affect the water intake of the submarine door (valve), thereby affecting the driving force of the boat; 3. The performance of the boat's slewing, maneuvering, and seakeeping will deteriorate

Embodiment 1

[0020] Example 1 as figure 1 , 2 , Shown in 4 and 5, it is an adjustable type split lift plate and stern lift plate structure, including a hull, the left, right and front parts of the hull are the boat outline 11, the bottom is the bottom 12, and the tail is the hull The stern seal plate 10, the boat outline knuckle line 9 is formed at the junction of the boat outline and the bottom surface of the boat bottom. The wedge plate 6 is symmetrically installed at the front part of the starboard two sides apart from the 40% of the bow of the boat. The wedge plate is trapezoidal. The rod can be connected with the telescopic oil cylinder or air cylinder installed in the boat, so that the wedge-shaped plate surface and the bottom surface of the boat bottom form a variable inclination angle, forming an adjustable split lift plate, which can make the inclination angle α vary from 0 to 30 with the expansion and contraction of the telescopic rod. The range of ° changes, the front end of t...

Abstract

The invention relates to a skimming boat with a boat body provided with a march-past lifting board device, comprising a boat body. The middle-front parts of the port and the starboard of the boat bottom are provided with symmetrical wedge boards; and the boat tail is provided with a tail lifting board. The skimming boat is characterized in that the front end of the wedge board is connected with the bottom surface of the boat bottom; the board surface of the wedge board inclines backward to form an inclined angle with the bottom surface of the boat bottom; the wedge board extends to 6 / 10 to 3 / 10 of the width position of the bottom surface of the boat bottom from the side of the boat toward the middle line of the boat bottom; and the front end of the wedge board inclines backward from the side edge of the boat toward the middle part so as to form the march-past lifting board. The skimming boat reduces the running resistance, solves the problem that the negative pressure generated at themiddle part of the boat bottom influences the water inflowing of the door at the sea bottom and leads the running speed to be effectively improved; the skimming boat adopts an adjustable march-past lifting board and the tail lifting board, and adjusts the angle of the lifting board according to the difference of the sea condition and the running speed so as to lead the lifting force to reach minimum resistance when the running is stable; and when in turning, the skimming boat realizes coordinative inward inclination turning by means of leftward and rightward differential motion of the march-past lifting board and has minimum turning diameter.

Description

technical field [0001] The invention relates to a planing boat whose hull is provided with a split-type lift plate device, which can make the planing boat increase in volume Fourier number Fr =In the range of 2.0 to 3.2, increase the speed and improve the navigation performance. Background technique [0002] When the boat reaches a certain speed, the hull is lifted from the water, only part of the hull is in contact with the water surface, and most of the weight of the boat is supported by hydrodynamic forces. The boat in this sailing state is called a planing boat. When the planing boat sails at low speed, its navigation state is the same as that of a general displacement boat. However, when transitioning from low speed to gliding, the resistance changes greatly due to the influence of static buoyancy and dynamic lift. In order to reduce resistance, a wedge plate is usually added at the front or rear of the bottom of the boat, its function is to increase the dynamic lift...
