Embodiment Construction

[0018] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0019] Such as figure 1 and 2 As shown, the technical solution of the present invention is that some parameters of the hull are designed according to the formula E=L / H*C, and the value range of C is 0.85-0.95, wherein, E represents the lift-to-drag ratio, and L represents the uplift area Longitudinal length, H represents the vertical height of the drag surface, and C represents the reduction coefficient of the lift-to-drag ratio.

[0020] The hull can be a ground-effect hovercraft, and its structure can refer to the utility model patent with the authorized announcement number CN205417991U. When the ship is in a moored state, the buoyancy is provided by the hull drainage and the multi-stage reverse buckle buoyancy air cushion composed of the hu...

Abstract

The invention provides a ship body. Part of parameters of the ship body are designed according to the formula E=L / H*C, wherein the value of C ranges from 0.85-0.95, E represents the lift-drag ratio, L represents the longitudinal length of a hovering area, H represents the vertical height of the resistance surface, and C represents the lift-drag ratio reduction coefficient. By adopting the technical scheme, the ship body has a great advantage on the lift-drag ratio compared with the lift-drag ratio of mainstream aircrafts, the lift-drag ratio of the ship body is the value calculated according to the formula E=L / H*C, can reach 30 or above and is obviously higher than the lift-drag ratio (the value is 16) of Boeing 737-800 and also higher than the maximum lift-drag ratio (20) of currently-running ground effect air vehicles.

Description

technical field [0001] The invention belongs to the field of ships, in particular to a ship hull. Background technique [0002] At present, except that the ground-effect aircraft is put into use, there is no ground-effect hovercraft (a ship-type ground-effect vehicle that does not fly off the water surface all the time) to be put into use. Although the use of aircraft using ground effect has a bright future, there are still many technical obstacles in the development. It is the ground-effect aircraft that has many threats to navigation safety and comfort and the immaturity of design technology, which brings challenges to the design and use of ground-effect aircraft and limits the popularity of ground-effect aircraft. The specific indicators are as follows: the load ratio of the lift surface is too large, the power-to-weight ratio of the engine is too small, the overall power-to-weight ratio is too small, and the lift-to-drag ratio is too small. As long as such technical de...
