Inflatable sail system

Abstract

The invention discloses an inflatable sail system comprising a mast fixed to a deck, a sail, a take-up and pay-off line and a take-up and pay-off connecting line. The sail has a soft structure composed of two layers of cloth with edges connected with each other, and the two layers of cloth of the sail are made of parachute nylon cloth; the top of the sail is connected with a first air bag, and thefirst air bag is filled with gas with the density smaller than the air density. The first air bag is filled with hydrogen or helium; an inflating hole is formed in the first air bag; the top of the first air bag is connected with a second air bag, and the second air bag is filled with gas with the density smaller than the air density. The parachute nylon cloth is used as the material of the sail;compared with an existing sail material, the provided inflatable sail system enables the cost to be effectively saved; meanwhile, in order to enable the sail to rise into the high altitude more effectively, gas with the density smaller than the air density is used, so that the sail can be driven by air buoyancy to smoothly rise into the air.

Description

technical field [0001] The invention relates to the field of sky sail systems, in particular to an inflatable sky sail system. Background technique [0002] The main body of the skysail system is a giant kite made of ultra-light synthetic fiber, which is fixed on a 15-meter-high mast on the ship, and can generally rise to a height of 100 to 300 meters to catch the strongest The wind pulls the ship forward, which can reduce the fuel consumption of the ship's engine. [0003] Such as figure 1 As shown, it is a schematic diagram of the overall structure of the existing sky sail system. The existing sky sail system is composed of a mast 2 fixed on the deck 1, a sail 4, a retractable line 3 and a retractable connecting line 5, wherein the sail 4 is There is a soft structure composed of two layers of cloth, which unfolds along the wind under the action of the wind. The edge of the sail 4 is connected with a retractable connection line 5, and one end of the retractable connection...

AI Technical Summary

Problems solved by technology

[0004] At present, the sail 4 of the Tianfan system is made of ultra-light fiber fabric, which is expensive to manufacture and relatively complicated to maintain. The wind power is very limited. When the wind power is limited, it will inevitably increase the fuel consumption of the engine, which is not conducive to energy saving. Therefore, the current sail system cannot be effectively popularized and used on a large scale.
