Problems solved by technology

The defect of this ship is: the high-power fan needs to be driven by a high-power engine
As a result, the weight and manufacturing cost of the ship are increased
Simultaneously, also increased navigation fuel consumption and took up the limited space on board
As for the full-cushion hovercraft, the noise during navigation and the air-cushion apron cause a large amount of water splash due to the escape of air, which makes the air around the ship filled with thick sea water mist, which not only affects the vision of the driver and passengers, but also affects the air intake of the power unit. It also exceeds the required salt content by more than 200 times

Embodiment 1

[0023] Example one: figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , As shown, in the flat bottom hull 7, parallel two sides extending from the bottom of the ship, inserted into the water between the rigid two side walls 5 midship to the stern, there are one or more out of the bottom of the ship, inserted into the water parallel to the side wall 5 rigid The air baffle 11 forms an open front air passage 4 and two or more rear air passages 12 at the bottom of the ship. The front end and the stern end of each rear air passage are provided with two adjustable angles. One or more front valves 9 and rear valves 13 are provided at the bottom of the bow of the front air passage 4 with a bow-shaped air inlet 2 with a larger section than the front air passage 4 and a bow flared at a high angle of attack α.

Embodiment 2

[0024] Embodiment two: Figure 7 , Figure 8 , Picture 9 As shown, in the flat-bottomed hull 7, the parallel sides extend out from the bottom of the ship and are inserted between the rigid two side walls 5 in the water from the bow to the stern. There are one or more rigid partitions extending from the bottom of the ship and inserted into the water parallel to the side walls 5. The air plate 11 forms two or more open air passages on the bottom of the ship. Each air passage is provided with a front valve 9 and a rear valve 13 with adjustable angles in the middle and aft of the ship to separate the bottom of the ship. Form two or more front air passages 4 and rear air passages 12 with one side open. At the bow bottom of each front air passage 4, there is a flared shape with a section larger than that of the front air passage 4 and a high angle of attack α. The air inlet 2.

Abstract

The invention discloses an air craft, aiming at providing a fan with high power and without apron or special air filtering system. The air craft runs at high speed at the broad water area by draining water or runs at high speed deviating from the water surface. The air craft comprises a drain sailing flat bottom craft body, an energy, two boards in parallel extending out of the craft bottom, two rigid side walls inserted in the water, a passenger and cargo hold, a control cab, a thruster in the control cab for regulating the respective rotation angle of the front air valve and the back air valve and an rudder operation transmission mechanism. The air craft is characterized in that one or more rigid air isolation board in parallel with the side wall, extending out of the bottom and inserting into the water are arranged from the middle part to the tail part of the craft between two side walls of the bottom. One front air flue and two or more back air flues with the opening next face are formed on the bottom. A front air valve and a back air valve with adjustable angles are arranged at the front end and tail end in each back air flue. A high incidence alpha bow bell mouth-shaped air inlet is arranged on the bow bottom of the front air flue, whose cross section is larger than that of the front air flue.

Description

Technical field [0001] The present invention relates to the field of ships, and in particular to a spacecraft that sails in open water with drainage or sails off the water surface at high speed. Background technique [0002] Since humans have used the canoe, they have been studying how to increase the speed of the boat. Conventional displacement ships are economical when sailing at medium and low speeds. However, to increase the speed of the ship, the resistance of the water must be overcome, and the required propulsion power increases in proportion to the third power of the speed. For example, when the ship's speed is increased from the original 10km / h to 30km / h, the propulsion power needs to be increased by 27 times, thus setting obstacles to the increase in the speed of the drainage-type ship. [0003] It can be seen from the material density table that the density of air is 800 times smaller than that of water. At the same speed, air resistance is insignificant compared to wa...
