Description

Wing-In-Ground effect ship for vertical taking-off and landing}

The present invention relates to a wing-in-ground effect ship, and more particularly, to a stable operation in the form of a catamaran ship, and to efficiently distribute and convert the engine power to lift and propulsion. It relates to a wig ship capable of vertical takeoff and landing with a power transmission structure.

In general, a wig ship is a new concept of water vehicle, which is operated at a level of 1 to 5 m above the water surface. The Wig ship uses the ground effect, which increases the lift of air as the wing gets closer to the surface, and is a complex of high-tech ship technology and aviation technology.

Since the Wig ship has no friction with the surface of the water, it can operate at 150 to 500 km / h, and thus the transportation efficiency is improved by two to three times compared to the aircraft or ships of the same class. In addition, comfortable navigation is possible without being affected by waves, and there is an advantage in securing safety because it operates at a low altitude. At present, the Wig ship is expected to be the next generation of maritime vehicles aiming to operate domestic coastal routes or relatively close China and Japan.

1 is a perspective view showing an example of a wig line according to the prior art. Conventional wig wire (1) is a technical limitation, usually produced in a small size of 1 to 6 seater, is provided with a propeller 20 for generating a thrust behind the hull (10). At this time, the wig wire 1 requires a thrust corresponding to about three times the thrust required at the time of cruising until the completion rate is reached due to friction with the water surface. Accordingly, the conventional wig wire 1 is used with a high-power engine, the size and weight of the engine is inevitably increased compared to the aircraft of the same class. This is one factor that hinders the transportation efficiency of the wig ship (1).

In addition, the conventional wig ship 1 can be operated only in the water, so the utilization conditions are extremely limited due to the limit of completion and landing ability (significant wave height 0.3m) in the blue, which is the biggest obstacle to the commercialization of the wig ship.

In addition, since the hull 10 of the wig line 1 has the same shape as a fuselage of a normal aircraft, there is a problem that it is difficult to secure a sufficient mounting space without the enlargement of the wig line 1.

In addition, since the propeller 20 is exposed to the outside in the conventional wig wire 1, the thrust is dispersed, there is a risk that a safety accident occurs. In addition, the distance between the thrust line of the propeller 20 and the center of gravity (C · G) of the wig wire (1) is far, there is a problem that the propulsion efficiency is greatly reduced.

Furthermore, in the conventional wig wire 1, since the main blade 30 is fixed to the hull 10, it is difficult to pass through a narrow waterway and a port facility, and there is a risk that the main blade 30 is damaged by the collision. In addition, when the wig ship 1 is moored in the port there is a problem that takes up a lot of space.

First, in adding reference numerals to components of each drawing, the same reference numerals are used for the same components as much as possible even if they are shown in different drawings.

[First Example ]

First, with reference to the accompanying drawings will be described with respect to the wiggline capable of vertical take-off and landing according to the first embodiment of the present invention.

(First Example  Configuration of the Wig line according to)

FIG. 2 is a perspective view of a wig line capable of vertical takeoff and landing according to the first embodiment of the present invention, FIG. 3 is a bottom perspective view of FIG. 2, and FIG. 4 is a side view of FIG. 2. Wig wire 100 according to the first embodiment of the present invention is largely the main body 110, the twin hull (120a, 120b), the main wing 130, the first propeller 150, the propulsion duct (160a, 160b) ), Vertical tail wings (170a, 170b), consists of a horizontal tail wing (180). At this time, the hug wire 100 is composed of a main hull 110 and a pair of catamaran hull (120a, 120b) has a shape such as a catamaran ship as a whole.

The main hull 110 has a horizontal cross-section of the overall rectangular shape, the circular floating duct 112 through which the floating force is generated in the center is formed vertically through. At this time, the main body 110 has a streamlined shape, such as airfoil (airfoil) from the bow to the stern as a whole. Therefore, since the wig line 100 has a structure in which the main body 110 is lifted together with the main wings 130, the operating efficiency is greatly increased, and the wig line 100 can be enlarged. On the other hand, the cockpit 114 is provided on the bow side of the main body 110, the passenger or cargo mounting portion 116 is provided on the stern side. At this time, the passenger or cargo mounting unit 116 is a structure that ensures a larger receiving space than the conventional Wig ship, and when the Wig ship 100 is enlarged, it is possible to mount a large amount of passengers or cargo can greatly improve the transportation efficiency. .

The catamaran hulls 120a and 120b extend downward from both sides of the main hull 110, respectively. That is, the first twin hull 120a and the first twin hull 120b are formed at both sides of the main hull 110 in the longitudinal direction of the main hull 110 so that the Wig line 100 has the same shape as the cathodic line as a whole. Will have. At this time, according to the present embodiment, the first and second catamaran hulls 120a and 120b have a plate shape having a predetermined thickness. Accordingly, the first and second catamaran hulls 120a and 120b guide the flow of air during cruising of the wig ship 100 to increase lift generation and enable stable operation, which is a general feature of catamarans. In addition, during landing, it serves to support the main body 110 in contact with the ground.

5 is a conceptual diagram for explaining a canard. On the other hand, the main body 110 is provided with a plate-shaped canard (117) that is hinged to the fore-front front end. The canard 117 has an airfoil shape whose vertical section is vertically symmetrical, and can adjust the angle of attack like an elevator of an aircraft. The canard 117 serves to prevent a phenomenon in which the wig line 100 becomes difficult to maintain a constant altitude, that is, a pitch-up phenomenon due to a sudden rise of a player by a momentary gust or the like. This pitch-up phenomenon is a big problem in the stability of the wig line 100 is designed to operate at low altitude (usually 1m ~ 5m). According to this embodiment, the canard 117 is automatically operated to maintain the 3 ° ~ 4 ° when the angle of attack of the main hull 110 is 2 ° ~ 5 ° of the optimal state to lower the bow. That is, lift force is generated in the downward direction by raising the canard 117 and passing air from the bottom upward as shown in FIG. 5A. Due to this, the bow of the main hull 110 is lowered and the operating altitude of the wig ship 100 is kept constant. On the contrary, when a pitch-down phenomenon in which a player suddenly descends due to bad weather or the like occurs, as shown in FIG. 5B, the canard 117 is lowered and air is passed from top to bottom. To generate lift. Therefore, the bow of the main body 110 is raised to maintain a constant flight altitude of the wig ship 100.

Meanwhile, as shown in FIG. 3, the main body 110 is provided with plate-shaped main body flaps 118 and 119 hinged to the bow side and the stern side of the lower surface, respectively. The main hull flaps 118 and 119 can temporarily trap the air injected from the floating duct 112 with the above-described twin hulls 120a and 120b as they descend from the lower surface of the main hull 110, Accordingly, it serves to increase the flotation force of the wig line 100.

The main wing 130 is formed to extend horizontally on both side ends of the main body 110 to generate a lift. The main wing 130, as shown in Figure 3 is provided with a main wing flap 132 to increase or decrease the lifting force generated in the front or rear side. In addition, the middle portion of the main wing 130 is provided with a guide 133 to guide the flow of air or water to help the stable operation of the wig wire 100. Meanwhile, according to the present embodiment, the main wing 130 has a collapsible structure as shown in FIG. 5. That is, the main body 110 and the main wings 130 are connected by the first link 134, and the middle portion of the main wings 130 is connected by the second link 135. The first link 134 is folded by a hydraulic or electric actuator (not shown), and the second link 135 has a two-stage folding structure that is folded or kinematically folded by an actuator (not shown). .

7A is a conceptual diagram illustrating a first propeller and a vane, FIG. 7B is a conceptual diagram illustrating a cyclic pitch control of a first propeller, and FIG. 8 is a conceptual diagram illustrating a power transmission structure of a wig line.

As shown in FIG. 7A, the first propeller 150 is rotatably installed in the floating duct 112 formed in the main body 110 and receives power from the engine 140 shown in FIG. 8. The first propeller 150 serves to float the wig line 100 by injecting air into the lower portion of the floating duct 112. On the other hand, the floating duct 112 is provided with a plurality of vanes 113 to the lower side of the first propeller 150 for converting a part of the floating force to the thrust of the wig wire 100. In addition, as shown in FIG. 7A, the vane 114 may be further provided on the upper side of the floating duct 112 so that air is smoothly introduced into the floating duct 112 when the wig line 100 is injured or cruised. . In this case, the vane 114 may serve to block the inflow of air when the first propeller 150 is not operated when the wig line 100 is cruised.

In addition, the first propeller 150 is applied to the general rotor technology of the helicopter. At this time, the first propeller 150 may be provided with only one rotor, it is preferable that the coaxial inverted rotor technology provided with two rotors is applied. According to this embodiment, the first propeller 150 includes an upper rotor 154 and a lower rotor 156 that rotate in opposite directions as shown in FIG. 8B. At this time, the lower rotor 156 having a hollow shaft is connected to the engine 140 by the bevel gear 144, the shaft of the upper rotor 154 is inserted into the hollow shaft of the lower rotor 156 bevel gear 144. Coaxial reversal is achieved by rotating by (). (The structure of the coaxial reversing rotor is easy for those skilled in the art. Accordingly, the torque between the upper rotor 154 and the lower rotor 156 is offset, thereby preventing the rotation of the Wig wire 100 itself. In addition, the coaxial reversing rotor has the advantage that the lift amount of 1.7 times larger than the single rotor is generated. In addition, since a separate device for offsetting torque is not required, the structure of the wig line 100 may be simplified.

On the other hand, each of the coaxial inverting rotor (154, 156) is applied to the cyclic pitch control (cyclic pitch control) technology to control the direction of the floating force by controlling the inclination of the inclined plate as shown in FIG. As a result, a part of the floating force can be switched to the thrust of the wig wire 100, and the horizontal direction control of the wig wire 100 is possible. In addition, a collective pitch control technique capable of controlling the lift, that is, the magnitude of the floating force, is applied by adjusting the pitches of the rotors 154 and 156. Such cyclic pitch control and collective pitch control is a general technique of a coaxial inverted helicopter, so a detailed description thereof will be omitted.

The propulsion ducts 160a and 160b are provided with the second propellers 162a and 162b on both upper ends of the stern of the main body 110, respectively. In addition, the second propellers 162a and 162b embedded in the respective propulsion ducts 160a and 160b receive power from the engine 140 to generate thrust behind the main body 110 as shown in FIG. 8. do. In addition, the wings of the second propellers (162a, 162b) has a structure capable of pitch control to adjust the magnitude of the thrust, it can act as a kind of brake by generating the thrust in the opposite direction through the reverse pitch control. On the other hand, the wig wire 100 is provided with a propulsion duct (160a, 160b) on the left and right sides of the main body 110, as shown in Figure 4, according to the thrust line of the propulsion duct (160a, 160b) Close to the center of gravity (C · G) of 100). For this reason, it has the propulsion efficiency superior to the conventional wig wire. In addition, since the air injected from the second propellers 162a and 162b is guided by the propulsion ducts 160a and 160b, it is possible to prevent the thrust from being dispersed, and since the second propellers 162a and 162b are not exposed, safety The risk of an accident is avoided.

In addition, the propulsion ducts (160a, 160b) is further provided inside the elevator 164 to control the direction of the thrust up and down as shown in 9a and 9b. The elevator 164 is responsible for the vertical direction control of raising or lowering at the time of stopping the wig line 100 or the attitude control at low speed and cruising of the wig line 100.

The vertical tail wings 170a and 170b extend on both upper ends of the main body 110 so as to be located behind the second propellers 162a and 162b. At this time, the rudder 172 is installed on the vertical tail wings 170a and 170b to enable horizontal direction control of the wig line 100.

The horizontal tail wings 180 are supported by the upper ends of the vertical tail wings 170a and 170b, and serve to generate lift. In addition, an elevator (not shown) may be installed on the horizontal tail wing 180 to enable vertical direction control of the wig line 100.

On the other hand, the power transmission structure of the wig wire 100 is shown in Figures 8a and 8b. The engine 40 is provided inside the main body 110, and the transfer 142 connected to the engine 40 includes the first propeller 150 and the propelling ducts 160a and 160b provided in the floating duct 112. Power distribution to the second propeller (160a, 160b) embedded in the) is transmitted. That is, as illustrated in FIG. 8B, the transfer 142 has a transmission structure and converts rotation speeds of the power transmission shafts 145 and 146. At this time, the first power transmission shaft 145 generates the floating force by driving the upper rotor 154 and the lower rotor 156 by coaxial inversion by the first bevel gear portion 144a. The second power transmission shaft 146 rotates the pair of third power transmission shafts 147a and 147b by the second bevel gear portion 144b, respectively, and the third power transmission shafts 147a and 147b. Each generate thrust by rotating the 2nd propellers 162a and 162b by the 3rd bevel gear part 144c, respectively. At this time, the second propellers (162a, 162b) is preferably configured to rotate in opposite directions to each other to cancel the torque. As a result, during the vertical takeoff and landing of the wig line 100, all the power of the engine 140 is used to drive only the first propeller 150 of the floating duct 112 to generate only the floating force, and the engine 140 during the cruise. By using a part of the power to drive the second propellers (160a, 160b) of the propulsion duct (160a, 160b) it is possible to convert a portion of the floating force to thrust.

(First Example  Operation of the wig wire)

Hereinafter, with reference to the accompanying drawings will be described the operation of the wigline 100 capable of vertical take-off and landing having the above-described configuration.

FIG. 9 is a conceptual view illustrating the operation of the wig line capable of vertical takeoff and landing according to the first embodiment of the present invention. As shown in FIG. 10A, the wig line 100 of the present invention can be vertically completed and embarked in the water phase by the floating force generated by the first propeller 150 of the floating duct 112, as well as vertical in the land. Take off and landing is possible. That is, when the wig line 100 vertically takes off or takes off, the power of the engine 140 is 100% transmitted to the first propeller 150 by the transfer 142, and the first propeller 150 is a floating duct ( 112) to inject air to the bottom. At this time, the hull lower flaps 118 and 119 are lowered by about 90 ° from the lower surface of the main hull 110. Therefore, the injected air is trapped between the twin hulls 120a and 120b and the hull lower flaps 118 and 119 and the ground or the water surface, which increases the floating force of the wig line 100 so that the wig line 100 is vertical. You can take or take off. On the other hand, the launch or landing of the wig line 100 is possible by gradually reducing the floating force of the first propeller 150 in the maximum state. Therefore, the wig ship 100 of the present invention is capable of vertical takeoff and landing in the water or on the ground so that it can be operated at all times regardless of the sea conditions such as blue.

10B is a conceptual diagram illustrating a case in which the wig line 100 of the present invention moves forward and takes off. When the wig line 100 is taken off while moving forward, the power of the engine 140 is transferred by the transfer 142 to the first propeller 150 of the floating duct 112 and the second propeller of the propulsion ducts 160a and 160b ( And distributed to 162a and 162b, respectively. For example, 50% flotation and 50% thrust can be generated. In this case, the hull lower flaps 118 and 119 are lowered by about 45 ° from the lower surface of the main body 110 so as not to disturb the air flow when the wig line 100 is advanced. Accordingly, the wig line 100 may take off while moving forward by the lift force generated by the first propeller 150 and the lifting force generated by the main body 110 and the main wing 130 as the wig line 100 is advanced. Will be.

10C is a conceptual diagram illustrating a case in which the wig line 100 of the present invention is cruised. In the case where the wig line 100 is cruising, lift force is generated in the main body 110 and the main wing 130 of the wig line 100 so that the propulsion ducts 160a and 160b are not operated even when the first propeller 150 is not operated. It is possible to operate only by thrust generated from). At this time, when the wig line 100 takes off or takes off, the vane 113 provided in the duct 112 or using the cyclic pitch control of the first propeller 150 to a certain altitude (about 1 to 5 m). To control the flotation to the thrust. In addition, when a certain altitude is reached, all the outputs of the engine 140 are used for propulsion, and ultra-high speed Hangzhou is possible. At this time, the hull lower flaps 118 and 119 are in close contact with the lower surface of the main hull 110 so as not to receive the resistance of the air. In addition, it is preferable to close the cover door (not shown) or the guide vane (not shown) installed on the upper portion of the floating duct 112 to smooth the air flow.

 As described above, the canard 117 maintains a constant flight altitude of the wig line 100 by preventing a pitch-up or a pitch-down phenomenon.

On the other hand, the completed or landing Wig ship 100 can be folded in the main wing 130, the anchoring space can be minimized by anchoring in the port or ground. In addition, in the state where the main wing 130 is folded, it is possible to easily pass through a narrow waterway and a port facility.

In addition, the wig wire 100 is the first propeller 150, the second propeller 162a, 162b, the transfer 142, the vane 113, the canard 117, the main body flaps 118, 119, the main Using the wing flap 132, elevator 164, rudder 172, etc., attitude control and various flight control is possible. Therefore, it can actively cope with bad weather, gusts and other emergencies, and stable operation is possible.

[Second Example ]

Next, the Wig line according to the second embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 11 is a rear view of a wig line for describing a catamaran hull according to a second embodiment of the present invention, and FIG. 12 is a view schematically showing a conventional catamaran line. As shown in Fig. 11, the wigline 100 " capable of vertical take-off and landing according to the second embodiment has the shape of the catamaran hulls 120a " and 120b " different from that of the first embodiment. Only the hulls 120a "and 120b" will be described.

FIG. 11A shows the state before completion of the wig line 100 ", and FIG. 11B shows the state after completion of the wig line 100". As shown in FIG. 11, the hull of the wig line 100 ″ is composed of the main hull 110 and the twin hulls 120a ″ and 120 b ″, and the twin hulls 120 a ″ and 120 b ″ have a wider landing area. In order to increase buoyancy, the lower part is curved in a semi-elliptic shape. Thus, the wig line 100 "according to the present embodiment of the catamaran hull 120a", 120b "in the water surface as shown in FIG. It has a structure in which the vertical distance S to the lowest part, that is, the draft is shortened. At this time, the draft S is the minimum height for the wig line 100 "to be taken. That is, as the draft S is shown in FIG. 11B, the bottom of the twin-hull 120a" and 120b "is the surface of the water. It is in contact with the minimum floating height (S) of the wig wire (100 ") is the minimum resistance.

For reference, the conventional catamaran 1 has a structure in which the draft S " is long because the vertical sections of the catamaran hulls 20a and 20b have an inverted triangle shape having a long length in the vertical direction. In other words, if the wig line 100 "of the present embodiment applies such conventional twin-hull hulls 20a and 20b, the minimum floating height S" is long, and large power is required for completion.

As a result, the wig line 100 ″ according to the second embodiment can be completed with a small power since the minimum floating height S is short. In addition, the wig line 100 ″ can maximize the surface effect and thus operate efficiency. Can be improved. On the other hand, as shown in Figure 11b the Wig wire 100 "is completed so that the end of the guide 133 formed in the lower portion of the main wing 130 during the forward flight to the minimum floating height (S) is designed to be submerged in the water surface This serves to help the stable operation of the wig line (100 "). As described above, the wig line 100 ″ according to the second embodiment has a shape optimized for navigation in the water.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, and all such changes and modifications are It is obvious that it belongs to the scope of the appended claims.
