Embodiment Construction

[0023] The present invention will be further described below in conjunction with specific examples, but the present invention is not limited by the examples.

[0024] The present invention proposes a three-body planing boat with channel wave suppressors. The planing boat uses the water flow in the channel to adjust the trim more quickly at the low speed stage. During high-speed navigation, due to the aerodynamic lift, the entire hull has After being lifted, only part of the bottom surface of the main hull slides on the water surface. At this time, the displacement of the flowing air-water mixture in the channel can be adjusted by adjusting the wave suppression plate. By reducing the displacement, the pressure in the channel can be further increased, thereby obtaining a higher pressure. Increase the height, reduce the wet surface area, and expand the upper speed limit to achieve higher speeds.

[0025] Such as Figure 1 to Figure 3 As shown, a three-body planing boat with a ch...

Abstract

The invention relates to a three-hull planing boat provided with a groove channel wave suppression plate, and belongs to the technical field of planing boat equipment. According to the three-hull planing boat provided with the groove channel wave suppression plate, the longitudinal trim of the boat is adjusted through the wave suppression plate, so that the three-hull planing boat crosses the lowspeed resistance peak value more quickly, in a high speed stage, the inner pressure of a groove channel is further increased by adjusting the wave suppression plate, thus the rising height is increased, the wet surface area is decreased, and a higher boat speed can be obtained; and the problems that adjusting of the three-hull planing boat is slow in a low-speed sailing stage and resistance is excessively high in a high-speed sailing stage are solved.

Description

technical field [0001] The invention relates to a three-body planing boat with a channel wave suppressor, and belongs to the technical field of planing boat equipment. Background technique [0002] The trimaran planing boat is widely used in military, official and civilian markets due to its rapidity and good stability at high speed, especially its excellent performance at high speed, which can easily reach a speed of more than 60 knots. It is mainly hydrodynamic before the skid, and when the entire contact surface is filled with air-water mixture after skidding, it is aerodynamic and hydrodynamic at this time. The air supports and lifts the entire hull, reducing the wet surface area and reducing the overall high-speed resistance. . Trimaran planing boats are different from conventional planing boats in that their resistance peaks appear in two stages, one is the low-speed stage and the other is the high-speed stage. The so-called low-speed resistance peak refers to the tr...
