Description

Ground effect enhancement and control device for a WIG craft}

The present invention relates to a device for enhancing and controlling the ground effect of the Wig wire.

Wig ship is also called ground effect blade or sea blade. It stands for 'Wing In Ground Craft' and it means super high speed ship moving on the surface of the water. In other words, the Wig ship refers to a high-tech ship combining high-speed ship technology that runs on water at high speed and aviation technology that floats on the surface.

The Wig ship is able to reach speeds of up to 550 km per hour as it uses lift, which is the basic principle of flying, along with the “ground effect”, which increases the lift of air that holds the hull as the wing approaches sea level. In other words, the Wig ship has a plate below the tip of the wing, which traps air between the wing and the surface, making it easier to fly directly above sea level.

The Wig was initially controversial over the question of whether it was a ship or a plane, but was classified as a ship by the International Maritime Organization (IMO) in the late 1990s. The Wig ship is several times faster than a normal ship, but can operate with much less fuel than an airplane and has the advantage of being amphibious. However, since the waves cannot rise from the surface of the water, they are mainly operated in lakes or rivers until now.

The Soviet Union began developing the Soviet Union in the 1960s for military purposes. Since then, Russia, Germany, and China have been developed for maritime rescue and leisure use, but are only partially used.

The introduction of the technology related to the Wig ship dates back to 1993. At the time, Korea-Russia science and technology exchange project was introduced to Korea. In 2002, the Korea Maritime Research Institute succeeded in piloting a four-seater leisure Wig ship after joint research with a domestic venture company. The Wig ship, which is called the `` sea gull symbol, '' can fly from 2m above sea level to 120km / h and consume less than 50% of a motorboat.

However, the Ministry of Maritime Affairs and Fisheries recently attracted attention after it plans to develop a large Wig ship (200 passengers) with a total project cost of 120 billion won. In fact, the Wig ship, which floats up to 5 meters above sea level, has been classified as a ship by the agreement of the International Maritime Organization (IMO) and the International Civil Aviation Organization (ICAO), but the principle of movement is much like an airplane. It is not unlike airplanes, in that they can lift at the wings and float in the air. The difference is that, unlike airplanes, it makes the most of the “ground effect”. The ground effect is a phenomenon in which more lift occurs than usual due to the trapped air under the wing when the wing is close to the surface.

In fact, it is impossible for a Wig ship to float like an airplane without a ground effect. Of course, if the plane flies low near the surface of the water or the ground, it will have the same ground effect as the Wig line, so the lift will be generated more efficiently on the wing. The problem is that airplanes are very dangerous if they come in contact with water, except for watercraft and flying boats. In other words, the principle of floating in the air is similar, but the Wig ship, which was originally designed to float on water, and the aircraft designed to fly in the air, have different directions of evolution.

After all, the greatest weakness of the Wigline comes from this ground effect. Due to the ground effect, the Wig ship flying at high speed may swing up and down as if the front part of the plane is waved. If the vibration becomes stronger, the plane may crash, collide with the surface of the water or be overturned in the air. In addition, the early Wig ship design technology can operate in lakes or rivers, but there is a limit in that it is impossible to take off and land due to the unstable ground effect at high altitudes. Fortunately, these problems are being solved one by one due to the development of control technology. However, the large Wig ship has yet to be developed.

If the research of the Korea Maritime Institute succeeds and the large wig ship is put to practical use, it is expected to drastically reduce the transportation time and cost. It is possible to operate at speeds of 200 ~ 500km / h, which is not possible with existing vessels, and it is only half as much as existing aircrafts in terms of fuel cost. In addition, the Wig ship does not have to attract large facilities such as airports like airplanes, so it is impossible to exclude the possibility of drastic changes in Northeast Asian logistics. In particular, there is no better way to connect passengers and air cargo to China, Yantai, Qingdao, Dalian, etc., as China does not have airport facilities but there is a lot of logistics. If the logistics can be solved with half of the airfare while operating Korea, the east coast of China and Japan within 1 to 3 hours, the ripple effect will be enormous. Of course, the mountains to be overcome are high and rough by then, but one thing is clear: a time when high-tech science and technology can dictate national competitiveness.

However, the existing wig wire is fixed in the shape of the wing, in order to obtain a greater ground effect, it is necessary to lower the altitude of the wig wire hanger or lower the position of the main wing as much as possible in the design stage.

The lift increase due to the ground effect is determined by h / c, where h is the distance between the wing's trailing edge and the surface, and c is the length of the wing's cord (the straight line between the leading and trailing edges). The smaller the h / c, the more the lift due to the ground effect increases exponentially. That is, the ground effect can be obtained by lowering the height of the wing (h) in the case of the same wing, and increasing the code length (c) of the wing when the wing height difference is not large. Can be.

When designing a wig line, an advantage should be taken into account. When applying a design that lowers the position of the wing relative to the hull (such as increasing the length of the cord of the wing or lowering the absolute position of the wing), the wig line floats on the surface of the water. Due to the effects of the tip of the wing being submerged in water, the wing may be damaged due to the great resistance of water in the state of launching or launching. In severe cases, the wing may be damaged. There are limits to the design that lowers the position.

In addition, even if you want to increase the lift by lowering the altitude of the Hug ship, there is a possibility that an accident may occur when the hug of the Wig ship hits the water, which also has a limit.

The present invention has been proposed in order to solve the above problems, the plate-shaped structure existing at the end of the wig wire wing extends in both the top, bottom or top and bottom of the wing to enhance the ground effect, the wig wire is water surface In the process of moving or launching from the ground, the plate-shaped structure is folded, but in the process of the Wig-line navigating above the surface, the plate-shaped structure is expanded to enhance the ground effect. In the process, the tip of the wing is submerged in the water and receives a great resistance from water, so that the wing is damaged or the hug of the ship is in contact with the water to lower the altitude of Hangzhou. To provide a device that can block the entire area and effectively enhance the ground effect of the wig line. Ever it shall be.

By maximizing the ground effect and controlling it, it is possible to ensure the operational safety of the Wig ship.

Other effects of the present invention, as well as those described in the above-described embodiments and claims of the present invention, as well as potential effects that may occur within the range that can be easily estimated therefrom and potential advantages that contribute to industrial development It will be added that it will be covered by a wider scope.

When the end of the wig ship extends downward and the wing approaches the surface of the wing, the air at the bottom of the wing is compressed to produce the air cushion effect. As a result, the pressure difference between the upper and lower wing increases, resulting in the ground effect. Figure 6 is an example of verifying the effect of the downward expansion of the end plate as described above, shows the calculation results by Fluent, a commercial code for computational fluid dynamics calculation. As shown in FIG. 6, when the distance from the bottom of the end plate to the ground is H, even if the distance between the wing and the ground is constant, the closer the end plate is to the ground, the greater the ratio of the lift due to the ground effect.

In Figure 6, the lift (lift) is a force generated by the pressure difference between the upper and lower wings according to the Bernoulli principle, causing the wig wire to rise above the surface of the water. The size of lift (L) is

L = CL ρ V2 S / 2 [L: lift (lb), CL: lift coefficient, ρ: density (slug / ft3), V: speed (ft / sec), S: wing area (ft2)] It can be represented as

Drag is a force that impedes the movement of a wig wire forward, and at the wing, fuselage, landing gear, strut, stabilizer, and other structures of the wig wire Occurs. Drag that does not help lift is called parasite drag. The magnitude of drag (D) is

D = CD ρ V2 S / 2 [D: drag (lb), CD: drag coefficient, ρ: density (slug / ft3), V: velocity (ft / sec), S: wing area (ft2)] (The above formula calculates the drag on the wing, and when calculating the drag of the whole Wig ship, CD and S should be considered for the whole Wig ship).

In addition, the ratio of lift and drag at a particular angle of attack is called the 'lift to drag ratio (L / D)' at the angle of attack.L / D is CL / CD, so the higher the ratio, Will increase the flight efficiency.

On the other hand, when the end plate is extended upward during the operation of the wig ship, the vortex generated at the tip of the wing is reduced, thereby increasing the efficiency of the wig ship, which is determined by the ratio of the two ports. Figure 7 is an example of verifying the effect of the upward expansion of the end plate as described above, and shows the calculation results by Fluent, a commercial code for computational fluid dynamics calculation. As shown in FIG. 7, when the end plate is extended upward, even if the distance between the wing and the ground is constant, the lift ratio due to the ground effect is increased (H / C = 0.2).

Accordingly, the present invention is to propose three types of devices that can enhance the ground effect of the Wig ship and increase the operating efficiency by extending the end plate of the Wig ship downward or upward through a simple operation. It will be described below in detail with the focus on the device according to 'Type 1', but the device according to the 'Type 2' and the 'Type 3' will be described mainly on the difference from the device according to the 'Type 1', and overlapping descriptions will be avoided. The device according to 'Type 1' extends the end plate of the Wig wire downward, the device according to 'Type 2' extends the end plate of the Wig wire upward and the device according to the 'Type 3' It is a device that can enhance the ground effect of the Wig ship and increase the operating efficiency by simultaneously extending the end plate of the Wig ship upward and downward.

In addition, the following will describe a preferred embodiment of the present invention, but the technical idea of the present invention is not limited thereto and may be variously modified and modified by those skilled in the art.

One. Type  1 (see Figure 2)

First, the present invention is a device for enhancing or adjusting the ground effect in a state symmetrically installed on the left and right of the wing of the wig line, the body as a plate-shaped structure that is installed orthogonal to the wing of the wig line at the edge of the wing end of the wig line End plate 110 has a groove that is open downward to be inserted into the expansion plate 120; As a plate-shaped structure, at least one side of the front and rear sides of the body is formed with a thread that can engage with the expansion plate driving gear 130, the state of the expansion plate driving gear 130 is inserted into the end plate 110 Expansion plate 120 for sliding in the vertical direction according to the operation; And an expansion plate driving gear 130 installed in engagement with a screw thread formed in the expansion plate 120 at a side of the body of the end plate 110 and driven by a motor to slide the expansion plate 120 upward and downward. It proposes a ground effect enhancement and control device of the wig wire using the expansion plate drive gear including.

End plate 110 is a plate-shaped structure that is installed orthogonal to the wing of the Wig line at the edge of the wing end of the Wig line (see Fig. 1). The body of the end plate 110 has a groove that is opened downward so that the expansion plate 120 can be inserted.

The expansion plate 120 is a plate-shaped structure, any one or more of the front and rear sides of the body is formed with a screw thread that can be engaged with the expansion plate drive gear 130.

The expansion plate 120 is a sliding motion in the vertical direction in accordance with the operation of the expansion plate drive gear 130 in the state inserted into the end plate 110. In this case, if the size of the groove existing in the body of the end plate 110 is exactly the size of the expansion plate 120, due to the friction between the groove and the expansion plate 120, the expansion plate 120 cannot smoothly slide the groove, If the size of the expansion plate 120 is too large compared to the size of the expansion plate 120 during the sliding movement there is a risk that it may be separated from the end plate 110 to be careful.

The expansion plate driving gear 130 is installed in engagement with a screw thread formed on the expansion plate 120 at the side of the body of the end plate 110 and serves to slide the expansion plate 120 in the vertical direction by driving by a motor.

That is, the expansion plate 120 is a linear sliding movement in the up or down direction according to the rotation direction of the expansion plate drive gear 130, if the expansion plate drive gear 130 rotates in any one direction upwards in connection with this Sliding into the groove of the end plate 110, the expansion plate drive gear 130 is rotated in the opposite direction as in the above case when sliding in a downward straight line in connection with this to come out of the groove of the end plate 110 will be.

In order to effectively perform the above functions, it is preferable that the expansion plate driving gear 130 has a structure of 'pinion' and 'rack', in particular, in view of the relationship with the expansion plate 120.

Generally, a gear is a mechanical part that transmits rotation or power between two or more axes, and is classified into various types according to the relative relationship between two axes that transmit rotational motion.

Here, spur gears in which two axes are parallel have the teeth cut parallel to the axis, and are most commonly used. In the case of outward engagement, the rotations of the axes are reversed. If you want to rotate in the same direction, use the inner gear. In either case, the speed between the two axes is inversely proportional to the diameter of the gear.

At this time, the case where the spur gear diameter is infinite, the rack (rack), and the biting gear is called the pinion (pinion), the rack and pinion is used to change the rotational motion to reciprocating motion and to reverse the motion.

Therefore, in the case of the present invention, the expansion plate 120 serves as a rack, and the expansion plate driving gear 130 corresponds to a pinion.

In order to achieve structural or operational stability, two expansion plate driving gears 130 are preferably installed in the front and rear directions on the side of the body of the end plate 110.

When the expansion plate 120 comes out of the groove of the end plate 110 as a whole, the end plate 110 is extended downward. As a result, the wing of the wig wire becomes close to the surface of the water, and the air on the lower surface of the wing is compressed, so that the effect of the air cushion is generated, so that the pressure difference between the upper and lower wings increases, and the ground effect is enhanced.

At this time, the upper and lower lengths of the expansion plate 120 is preferably limited so as not to contact the water surface even when the expansion plate 120 slides downward to the outside of the groove of the end plate 110 as much as possible. If the expansion plate 120 is in contact with the water surface because the expansion plate 120 may be damaged by the resistance of the water.

On the other hand, it is preferable that the expansion plate driving gear 130 can control the displacement or the speed at which the expansion plate 120 slides according to the driving of the motor.

In this case, in the expansion plate driving gear 130, the expansion plate 120 is kept downward by keeping the expansion plate 120 fully inserted into the groove of the end plate 110 when the Wig wire is moving or moving on the water surface. There is no risk of being damaged by contact with the water surface in the down state, and by expanding the expansion plate 120 to the outside of the groove of the end plate 110 only when the wig line is floating in the water surface to enhance the ground effect.

In addition, the expansion plate driving gear 130 can properly adjust the insertion or expansion of the expansion plate 120 according to the sea state (the distance between the wing and the water surface), if the sea state in which the Wig ship is very rough The expansion plate 120 is fully inserted into the groove of the end plate 110 or left only slightly expanded, and the expansion plate 120 ends when the sea state in which the Wig line is Hangzhou is suitable for using the device according to the present invention. Extending to the outside of the groove of the end plate 110 as much as possible to derive the maximum ground effect.

In addition, the expansion plate driving gear 130 may control the expansion state of the expansion plate 120 which is installed symmetrically on the left and right sides of the wing in accordance with the movement state of the wig wire to promote the overall movement stability of the wig wire.

When the expansion plate 220 comes out of the groove of the end plate 210 as a whole, the end plate 210 is extended upward. As a result, the vortices generated at the tip of the wing of the Wig ship are reduced, thereby increasing the efficiency of the Wig ship, which is determined by the ratio of lift.

In order to effectively perform the above functions, it is preferable that the expansion plate driving gear 130 has a structure of 'pinion' and 'rack', in particular, in view of the relationship with the expansion plate 120. In this case, the expansion plate 120 acts as a rack, and the expansion plate driving gear 130 corresponds to a pinion.

As a result, the wing of the wig wire becomes close to the surface of the water, and the air on the lower surface of the wing is compressed, so that the effect of the air cushion is generated, so that the pressure difference between the upper and lower wings increases, and the ground effect is enhanced.

In this case, the upper and lower lengths of the lower extension plate 322 are preferably limited so that the lower extension plate 322 does not come into contact with the water surface even when the lower extension plate 322 slides downward and descends to the outside of the groove of the end plate 310 as much as possible. If the lower extension plate 322 is in contact with the water surface, the lower extension plate 322 may be damaged by water resistance.

The upper expansion plate driving gear 331 and the lower expansion plate driving gear 332 is preferably installed in the front and rear direction two at each side of the body of the end plate 310 in order to achieve structural or operational stability.

The upper extension plate driving gear 331 and the lower extension plate driving gear 332 may control the displacement or speed at which the upper extension plate 321 and the lower extension plate 322 slide according to the driving of the motor.

In this case, the upper expansion plate driving gear 331 and the lower expansion plate driving gear 332 independently control the displacement or the speed at which the upper expansion plate 321 or the lower expansion plate 322 slides by the motor is driven independently of each other. Accordingly, the degree of insertion or expansion of the upper extension plate 321 and the lower extension plate 322 may be different or the same. For example, the upper extension plate 321 is inserted but the lower extension plate 322 is extended. (It is also possible to reverse the case), a variety of states can be derived, such as when the upper expansion plate 321 and the lower expansion plate 322 is inserted or expanded at the same time.

In particular, the lower extension plate driving gear 332 has a lower extension plate 322 by maintaining the state in which the lower extension plate 322 is completely inserted into the groove of the end plate 310 when the wig line is moved or started at the water surface. There is no risk of being damaged by contact with the water in the down state, and the ground extension plate 322 is properly extended to the outside of the groove of the end plate 310 only when the wig line is injured from the water surface, thereby enhancing the ground effect. Let's go.

In addition, the lower extension plate driving gear 332 can properly adjust the insertion or expansion of the lower extension plate 322 according to the sea state (distance between the wing and the water surface), if the sea state in which the wig line is very rough In this case, the lower extension plate 322 is completely inserted into the groove of the end plate 310 or left only slightly extended, and the lower extension plate ( 322 is extended to the outside of the groove of the end plate 310 as much as possible to derive the maximum ground effect.

In addition, the upper extension plate driving gear 331 and the lower expansion plate driving gear 332 individually extend the upper expansion plate 321 and the lower expansion plate 322 which are installed symmetrically on the left and right sides according to the movement state of the wig line. It can be controlled to improve the overall motion stability of the wig wire.
