Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention provides a boat with a main wing,
The present invention relates to a water surface effect wing boat capable of achieving high speed performance by improving the wing characteristics due to the water surface effect in a state of traveling slightly above the water surface.

[0002]

2. Description of the Related Art Conventional water surface effect wing boats include those shown in FIG. 7 (plan view), FIG. 8 (side view) and FIG. 9 (front view), and the hull 1 has a main wing with a flap 2a. 2 and a horizontal stabilizer 3, a vertical stabilizer 5 and a tail rudder 6 mounted on the vertical stabilizer are provided. A pedestal 9 that supports a plurality of propellers 4 is provided at the front of the hull in front of the main wing 2. With such a structure, when the water surface effect wing craft changes direction while traveling above the water surface 10, the flap 2a and the tail rudder 6 are used.

[0003]

By the way, in the above-mentioned conventional water surface effect watercraft, since the direction change thereof mainly depends on the tail longitudinal rudder 6 having a small rudder area, swift turning operation can be performed. Can not. In addition, when the direction of the turn is changed, the hull 1 is tilted to the left and right to make a bank turn to obtain a turning force. When the flag 2a is rotated, the tip of the main wing 2 tilted downward comes into contact with the water surface 10. There is a fear.

Therefore, if a large vertical rudder 6 and a large vertical tail 5 that supports the large vertical rudder 6 are provided in order to obtain high turning ability without performing a bank turn, the resistance of the vertical tail 5 increases and the propulsion efficiency deteriorates. Will be done. The present invention is intended to solve such problems,
It is an object of the present invention to provide a water surface effect wing craft whose turning performance is improved by increasing the rudder area of a vertical rudder.

[0005]

In order to achieve the above-mentioned object, the water surface effect wing boat of the present invention has a wing characteristic due to the water surface effect in a state in which a hull is provided with a main wing and sails slightly above the water surface. In a water surface effect winged boat, the wing end plates fixed to be substantially orthogonal to the main wing are provided at both ends of the main wing, and a vertical rudder capable of turning operation is provided on the wing end plate. It is characterized by that.

Further, the water surface effect wing boat of the present invention is a water surface effect wing boat in which a wing characteristic is improved by a water surface effect in a state in which a hull is provided with a main wing and is traveling slightly above the water surface.
Both ends of the horizontal stabilizer provided behind the main wing were provided with wing end plates fixed so as to be substantially orthogonal to the horizontal wing, and a longitudinal rudder capable of turning operation was provided on the same wing end plate. It is characterized by that.

[0007]

In the above-described water surface effect wing craft of the present invention, since the rotatable longitudinal rudder is attached to the wing end plates fixed to both ends of the main wing or the horizontal stabilizer, the total rudder area of the vertical rudder is summed up. Can be made sufficiently large, whereby sufficient turning action can be performed without performing a bank turn in which the hull is tilted to the left and right.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the drawings. FIGS. 1 to 4 show a water surface effect wing boat as a first embodiment of the present invention. FIG. The side view and FIGS. 3 and 4 are explanatory views showing the action of the vertical rudder.

As shown in FIGS. 1 and 2, also in the case of the water surface effect wing boat of the first embodiment, the hull 1 has a main wing 2 and a horizontal stabilizer 3.
Besides, the vertical tail 5 and the tail longitudinal rudder 6 mounted on the vertical tail are provided. A pedestal 9 that supports a plurality of propellers 4 is provided at the front of the hull in front of the main wing 2. Further, in the water surface effect wing boat of the present embodiment, the wing end plates 7 fixed upright so as to be substantially orthogonal to the main wing 2 are provided at both ends of the main wing 2, and each wing end plate 7 is provided. Is equipped with a vertical rudder 8 which can be rotated.

Similarly, the horizontal stabilizer 3 is also provided with wing end plates 7a fixed at the opposite ends of the horizontal stabilizer 3 so as to be substantially orthogonal to the horizontal stabilizer 3, respectively. A vertical rudder 8a that can be rotated is attached to the end plate 7a. Each of the vertical rudders 8 and 8a described above is provided with an actuator (not shown) for rotating them, and the operation of each actuator is performed in response to an operation of a turning control member (not shown).

Since the water surface effect wing boat of the first embodiment is constructed as described above, the total sum of the rudder areas of the longitudinal rudders 8 and 8a can be made sufficiently large, as shown in FIG. 3 and FIG. As described above, the vertical rudder 8 on the wing end plates 7 on both ends of the main wing 2 is rotated, and the vertical rudder 8 on the wing end plates 7a on both ends of the horizontal tail 3 is operated.
By rotating a, for example, the turning action can be accurately performed without performing a bank turn in which the hull 1 is tilted to the left and right. Therefore, the contact of the tip of the main wing 2 with the water surface 10 as when performing a bank turn can be avoided.

The symbol F in FIGS. 3 and 4 indicates the lateral force generated when the vertical rudder 8 is rotated, and the symbol M indicates the turning moment. Further, by disposing the wing tip plates 7 and 7a and the vertical rudders 8 and 8a, these wing tip plates 7 and 7a are arranged.
a and the vertical rudder 8, 8a have a specific resistance, but the wing tip plate 7,
Since the lift-drag ratio of the main wing 2 and the horizontal stabilizer 3 is increased due to the influence of 7a, the total resistance does not increase.

Next, a water surface effect wing boat according to a second embodiment of the present invention will be described. FIG. 5 is a plan view thereof and FIG. 6 is a side view thereof. In addition to a main wing 2 and a horizontal tail 3, a vertical tail 5 and a tail longitudinal rudder 6 attached to the vertical tail are provided. A pedestal 9 that supports a plurality of propellers 4 is provided at the front of the hull in front of the main wing 2.

Further, in the water surface effect wing boat of the present embodiment, the wing tip plates 7 fixed by being suspended so as to be substantially orthogonal to the wing 2 are provided at both ends of the wing 2, respectively. A vertical rudder 8 which can be rotated is attached to the plate 7. An actuator (not shown) for rotating the vertical rudder 8 described above is provided, and the operation of the actuator is performed according to the operation of a turning control member (not shown).

Since the water surface wing boat of the second embodiment is constructed as described above, the sum of the rudder areas of the left and right longitudinal rudders 8 can be made sufficiently large, and the wing tips at both ends of the main wing 2 can be obtained. By rotating the vertical rudder 8 on the plate 7, the hull 1
Even if the bank turn for tilting the right and left is not performed, the turning action can be accurately performed. Therefore, the contact of the tip of the main wing 2 with the water surface 10 as when performing a bank turn can be avoided.

Further, by disposing the wing tip plate 7 and the vertical rudder 8, a specific resistance is generated in the wing tip plate 7 and the vertical rudder 8. However, due to the influence of the wing tip plate 7, the lift of the main wing 2 is increased. Due to the higher ratio, the overall resistance does not increase. In addition, propeller 4
When the wake is guided to the lower side of the main wing 2 to perform the water separating action, the blade end plate 7 suppresses the leakage of the air flow to the side, and thus the water separating effect can be enhanced.

[0017]

As described above in detail, according to the water surface effect wing boat of the present invention, the following effects can be obtained. (1) Since the rotatable rudder is attached to the wing end plates that are fixed to both ends of the main wing or the horizontal stabilizer, the total rudder area of the rudder can be made sufficiently wide. Sufficient turning performance can be obtained without performing a bank turn in which the hull is tilted to the left and right, and the risk of the wing tip contacting the water surface during turning can be avoided. (2) By arranging the wing tip plate and the rudder, specific resistance is generated in these wing tip plates and the rudder, but the lift-drag ratio of the main wing and the horizontal stabilizer increases due to the influence of the wing tip plates. Has the advantage of not increasing the overall resistance. (3) When the wing tip plate is installed so as to hang downward from the wing tip of the main wing, the wing tip plate causes leakage of airflow to the side when the propeller wake is guided below the main wing to perform water separation. Since it suppresses, the water separation effect can be enhanced.
