Both side ends of the skin portion 200 are exposed to the outside at the ship side portion (S), and both edges of the ship bottom portion (B) have a predetermined curvature in the upward direction due to the streamlined hull portion 100 . Due to this, the draft can ride up along the skin part 200 in the direction of both side ends of the skin part 200 and ride up to the inside of the hull part 100 or the upper part of the hull part 100, so to prevent this, the skin part ( A cover portion 101 surrounding the 200 may be further provided on the front side portion (S). The cover part 101 is provided in the shape of a surface or plate protruding along the side part S, and is provided in a shape to surround by overlapping both side ends of the skin part 200 by facing downward.

The port part 110 and the starboard part 120 are provided in a cylindrical shape, respectively, and air is filled therein. Although it has been described that air is filled, it can be replaced if the corresponding effect is satisfied through other means having buoyancy.

7 and 8, the skin control unit 250 is provided between the ship bottom (B) and the skin unit 200 to control the angle of the skin unit 200 with the other end positioned in the stern direction. . The skin control unit 250 is provided between the ship bottom (B) and the skin unit 200 , and is provided in both side end directions of the skin unit 200 , respectively.

The skin control unit 250 includes a first member 251 , a second member 252 , and a spring unit 253 .

The first member 251 is provided so as to be in contact with the ship bottom (B) and is formed along the longitudinal direction of the hull portion 100 . Although it is said that it is formed along the longitudinal direction, which is the longitudinal direction T1 of the hull part 100, it may be formed to have an angle in the longitudinal direction in consideration of the speed and use of the air boat. At this time, it is preferable to provide the first member 251 to be symmetrical with each other so that the skin control units 250 provided on both sides as a pair are symmetrical to each other.

A spring part 253 is provided between the first member 251 and the second member 252 . The spring part 253 is a configuration having a predetermined restoring force, and is provided between the first member 251 and the second member 252 to increase the distance between the first member 251 and the second member 252 by a predetermined restoring force. It is a configuration separated by

In addition, the first member 251 and the second member 252 are formed of a conductive material, or only the second member 252 is formed of a conductive member. The reason that it is provided with a conductive material is a configuration for hinged movement of the second member 252 in the direction of the ship bottom (B) through the electromagnetic force or magnetic force (E) generated in the magnetic force generating unit 300 to be described later. At this time, the restoring force of the spring part 253 so that the second member 252 can be hinged in the direction of the ship bottom (B) by the magnetic force (E) is lower than the force of the electromagnetic force or the magnetic force (E). When the electromagnetic force or magnetic force (E) is applied to the second member 252, the second member 252 generates a magnetic force (E) to move the hinge in the direction of the ship bottom (B), that is, the magnetic force generating unit (300). configure it to be

The magnetic force (E) control unit is configured so that the first member 251 and the second member 252 are superimposed on each other by applying an electromagnetic force or a magnetic force E to the skin control unit 250 according to a user's control designated in advance. The magnetic force (E) control unit may be composed of an electromagnet capable of generating a magnetic force (E) or an electromagnetic force according to a user's signal, or an electromagnetic force generating module.

When the magnetic force (E) control unit is operated according to the user's control specified in advance, electromagnetic force or magnetic force (E) is generated, whereby the first member 251 and the second member 252 are superimposed on each other and the skin part 200 The ship bottom part (B) and the skin part 200 have an acute angle with each other by being in close contact with the ship bottom part (B). This is defined as an acute angle mode of the skin part 200 (refer to FIGS. 7 and 10).

When the magnetic force (E) control unit does not operate according to the user's control specified in advance, the first member 251 and the second member 252 are spaced apart from each other by the restoring force of the spring part 253 positioned between each, Due to the skin portion 200 has an obtuse angle with the ship bottom (B). Through this, when the hull part 100 rotates at a predetermined angle through the operation part of the air boat, the skin part 200 becomes an obtuse angle with the ship bottom part B by the restoring force of the spring part 253, and the skin becomes an obtuse angle. Due to the part 200 is more affected by the draft, so that the turning radius of the hull part 100 is reduced. This is defined as an obtuse angle mode (refer to FIGS. 8 and 9).

As an additional embodiment, it will be defined that the magnetic force (E) control unit is further specified and limited. The magnetic force (E) control unit further includes a coil unit 310 and a bar unit 320 . The coil unit 310 may apply a magnetic force E to the rod unit 320 through an induced current using Faraday's law.

The coil unit 310 is formed on each of the port side part 110 and the starboard part 120 , and is provided in a spiral shape along each longitudinal direction of the port side part 110 and the starboard part 120 having a cylindrical shape. In addition, it is provided with a conductive material in order to receive a current from an external power.

The rod part 320 has a cylindrical rod shape penetrating the inside of the coil part 310 and is made of a conductive material.

When a current is applied from an external power to the coil unit 310 , an electromagnetic force is generated by a current flowing along the coil, and a magnetic force E is applied to the bar unit 320 by the electromagnetic force of the coil. At this time, the skin control unit 250 provided in the ship bottom (B) under the port side 110 and the starboard unit 120 by the magnetic force E of the rod unit 320 and the electromagnetic force of the coil unit 310 is Set it to acute angle mode.

In order to more effectively apply this configuration to the air boat, the air boat may be further provided with a manipulation unit. The manipulation unit may be a handle for controlling the moving direction of the air boat, a manipulator capable of controlling the direction of a screw located at the rear of the air boat, or a manipulator capable of controlling the direction of a wind power module installed at the rear side of the air boat.

Basically, when an airboat cruises in a straight direction, current is applied to the coil unit 310 to set the skin unit 200 to an acute angle mode, thereby increasing the operating speed and operating safety of the airboat.

In addition, when the operation unit rotates the hull part 100 at a predetermined angle specified by the user, the skin part 200 is spaced apart from the ship bottom (B) by blocking the current applied to the coil part 310 in an obtuse angle mode. It can be configured to reduce the turning radius by converting to .

By configuring the acute angle mode and the obtuse angle mode as described above, it is possible to increase the navigation speed by reducing the draft through the acute angle mode, and to reduce the turning radius through the obtuse angle mode when the hull part 100 rotates, and driving on land or ice The obtuse angle mode can be used even when driving, and it can act as a cushion to absorb damage such as driving safety or vibration.
