Embodiment Construction

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

[0019] Such as figure 1 with 2 As shown, the technical solution of the present invention is that part of the 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, where E represents the lift-to-drag ratio, and L represents the cushioning zone Longitudinal length, H represents the vertical height of the resistance surface, and C represents the lift-to-drag ratio reduction coefficient.

[0020] The hull can be a ground-effect hovercraft, and its structure can refer to the utility model patent authorized announcement number CN205417991U. When the ship is at berth, the multi-stage back-buckle pontoon air cushion composed of hull drainage and hull side plates, decks and water skis 1 provides buoya...

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, especially a ship hull. Background technique [0002] At present, in addition to the ground-effect aircraft being put into use, no ground-effect hovercraft (ship-type ground-effect vehicles that never fly off the water) have been put into use. Although the use of ground effect aircraft has broad prospects, there are still many technical obstacles to the development. It is precisely that ground-effect aircraft have many threats to the safety and comfort of navigation and the immaturity of design technology, which brings challenges to the design and use of ground-effect aircraft, and limits the popularization of ground-effect aircraft. The specific indicators are as follows: the lift surface load ratio is too large, the engine power-to-weight ratio 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 shortcomings are systematically resolv...
