A Metal Air Cushion Jet Recycling Ship Structure

Abstract

The invention discloses a metal air cushion jetting recovery ship structure, which includes a hull, and the midship part of the hull is composed of at least two independent balance air chambers, and the bottom of each air chamber is an open opening; the midship part of the hull There are also connected nozzles and air cylinders, said nozzles tightly fitting with each air chamber. Compared with the prior art, the present invention has the advantages of safety, stability, small navigational resistance, energy saving and emission reduction, low shipbuilding cost and no limitation of deadweight tonnage, and can be widely applied to various ships. jet, which acts to propel the hull forward. Recycling: It makes the air chamber of the hull produce a saturated air cushion, which produces the air flotation effect of the hull; the air flotation changes the specific gravity of the hull, which is beneficial to the utilization of equipment power and energy saving; it increases the physical sliding inertia of the hull, thereby increasing the sliding of the hull. Power, favorable utilization of equipment power, energy-saving effect. That is to say, injection and recovery have multiple functions at once.

Description

Technical field [0001] The invention relates to a ship, in particular to a metal air cushion jet recovery ship structure used for surface navigation. Background technique [0002] At present, the bottom of ordinary ships is sealed, and it needs to consume a lot of energy to overcome the resistance of water when sailing on the surface; the deeper the draught of the ship, the greater the resistance during navigation, which makes the speed of ordinary ships slower, usually not More than 30 knots. On this basis, through continuous efforts of people, the hovercraft was invented. The hovercraft is equipped with inflatable cushions on both sides or bottom of the hull. When sailing, the hovercraft is inflated into the air cushion, and the hull is raised close to the water surface, and the hovercraft is stabilized by wing knives on both sides , Which greatly reduces the water resistance during sailing, and the ship speed can be increased to 40-60 knots, but the hovercraft also has fatal ...

Problems solved by technology

On this basis, after people's continuous efforts, the hovercraft was invented. The hovercraft set up inflatable cushions on both sides or bottom of the hull, inflates the air cushions during navigation, raises the hull close to the water surface, and uses the wing blades on both sides to stabilize , which greatly reduces the resistance of the water during navigation, and the speed of the ship can be increased to 40-60 knots, but the hovercraft also has a fatal shortcoming. Because it needs to flush and deflate the air cushion, it is affected by the power of the engine, so that the load capacity of the hovercraft It is greatly restricted, and generally can only form a load of several hundred tons. At the same time, its energy consumption is astonishing, and it can only be used in special occasions such as short-distance personnel transportation and military transportation.
