Embodiment Construction

[0025] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the embodiments of the present invention are described below with the aid of the drawings; obviously, the following drawings are only some embodiments of the present invention, and are not restrictive to the present invention. limited.

[0026] See attached figure 1 , the present invention includes a hull 20 and an aircraft 10, the aircraft 10 is installed on the bottom of the ship 20, the lowest part of the aircraft 10 is not lower than the bottom of the ship 20, and the hull 20 is lifted to the water surface by the aircraft 10 during navigation and through the formation of supercavitation around the aircraft 10, the driving resistance is greatly reduced.

[0027] See further attached figure 2 , wherein, the hull 20 includes at least a pair of catamaran (double boat) hulls, which are connected to each other by connecting decks 24 . Each catamara...

Abstract

The invention discloses an energy-saving glider capable of increasing the advancing speed of a ship, which is applied to a ship body 20, wherein the ship body 20 at least comprises a pair of catamaranship bodies which are connected with each other through a connecting deck 24, an aircraft 10 is installed at the bottom of the ship body 20, and the lowermost part of the aircraft 10 is not lower than the bottom of the ship body 20; an aircraft 10 is arranged at the lower part of the connecting deck 24, the aircraft 10 comprises an aircraft wing part 11 and a connecting part 12, the aircraft 10 is connected to a connecting deck 14 through the connecting part 12, the aircraft wing part 11 is provided with an attack angle, the connecting part 12 is of a hollow structure, and the aircraft wing part 11 is communicated with the hollow structure of the connecting part 12 through an opening; and the aircraft wing part 11 of the aircraft 10 is provided with an inner cavity of a hollow structure,a plurality of air outlet holes 40 are formed in the surface of the aircraft wing part 11, the aircraft 10 is used for supporting the ship body 20 towards the water surface in the navigation process,and supercavitation is formed around the aircraft 10, so that the driving resistance is greatly reduced.

Description

technical field [0001] The invention relates to the field of high-speed ships, and relates to a glider for increasing the speed of the ship, in particular to a glider for reducing drag by using supercavitation. Background technique [0002] Current ships such as container ships, bulk carriers, oil tankers, high-speed ships and other traditional ships sail due to frictional resistance due to the contact between the hull and water. The resistance of objects moving in water is proportional to the square of the speed. To maintain a constant underwater velocity, the object's propulsion system must provide at least as much energy as is necessary to overcome underwater resistance. However, the energy required to propel an underwater object is proportional to the cube of the speed, that is, to double the speed, the propulsion system must provide 8 times the energy. Therefore, it is obviously very limited to increase the speed obviously through conventional methods. [0003] The ca...
