Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steering blade used in an aerodynamic steering device for a flying vehicle.

[0002]

2. Description of the Related Art In a conventional steering wing, an expansion hinge portion 2 is provided in the steering surface as shown in FIG. 7, and the steering surface is divided into a steering surface 10 and a steering surface 11. Then, only the steering surface 10 was expanded when the steering surface was expanded. When steering, the steering surface 10, the expansion hinge portion 12, and the expansion hinge portion 12 are rotated by the rotation of the steering shaft 13 connected to the steering surface 11.
The steering surface 11 has rotated.

According to this conventional steering blade, when the steering wheel is steered, the expansion hinge portion 12 protruding from the steering surface causes
Turbulence of the air flow occurs and steering efficiency is reduced. Even if it is attempted to provide the expanded hinge portion 12 in the body 9 to avoid this, the expanded hinge portion 12 cannot be provided in the body 9 because the expanded hinge portion 12 also rotates.

As described above, in order to prevent the expansion hinge portion 12 projecting from the steering surface from disturbing the airflow and lowering the steering efficiency, as shown in FIG. In some cases, the thickness and length of the steering surface were increased so that 12 could be accommodated within the steering surface. In the steering blade shown in FIG. 8, since the thickness of the steering surface is large, the cross-sectional area of the steering surface is large and the air resistance is increased.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wrought steering wheel that does not have the drawbacks found in the prior art described above by solving the following two items. (1) The extended hinge portion that causes the turbulence of the air flow and reduces the steering efficiency is not provided in the steering surface. (2) The thickness and the length of the steering surface are maintained so that the air resistance is not increased by increasing the thickness and the length of the steering surface.

[0006]

In order to solve the above problems, the steering blade according to the present invention adopts the following configuration. According to the present invention, a steering surface is provided outside a stretched hinge portion, and a steering shaft that rotates the steering surface has a steering shaft hinge portion that penetrates the stretched hinge portion and is bendable together with the steering surface at the stretched hinge portion. Have

Further, in the steering wing according to the present invention, in the above-mentioned steering wing, the expanded hinge part is supported by the flying body, and the steering shaft support part is foldably connected around the hinge part, and A structure in which the steering surface is arranged outside the shaft support part is also adopted.

[0008]

In the steering wing according to the present invention, by adopting the above-mentioned configuration, there is no expansion hinge part in the steering surface, and the steering shaft for rotating the steering surface outside the expansion hinge part is the expansion hinge. Although extending through the portion, the steering shaft is provided with a steering shaft hinge portion on the expansion hinge portion, so that the steering surface can be bent together with the steering shaft.

Further, according to the present invention, in the above-mentioned steering wing, the extended hinge portion is supported by the body of the flying body, and the steering shaft support portion is foldably connected around the extended hinge portion. In the case where the steering surface is arranged on the outside of the steering shaft, the steering shaft support part is folded around the stretch hinge part together with the steering shaft.

As described above, in the steering wing according to the present invention, since the expansion hinge portion is removed from the steering surface, the steering efficiency is not reduced by disturbing the air flow on the steering surface.
Further, it is not necessary to increase the thickness or length of the steering surface.

[0011]

The steering blade according to the present invention will be specifically described below based on an embodiment. First, a first embodiment of the present invention will be described with reference to FIGS. 1, 2 and 3.

A steering shaft 5 for rotating the steering surface 1 is connected to the steering surface 1. The steering shaft 6 is connected to the steering shaft 5 by a steering shaft hinge portion 7 so that the steering shaft 6 can be folded laterally at the steering hinge portion 7.

Next, the steering shaft 6 and the steering shaft 5 are passed through the steering shaft support portion 2. The steering shaft support portion 2 and the joint portion of the fuselage body 9 of the flying body are joined by the extended hinge portion 3 and the extended hinge portion 4, and the steering shaft 6 and the control device 8 are connected.

With this coupling, during steering, the steering shaft 6 and the steering shaft 5 rotate due to changes in the steering angle from the control device 8, and the steering surface 1 rotates around the steering shaft (FIG. 2).
reference).

When the steering blade is extended, the extended hinge portions 3 and 4
When the steering shaft support part 2 expands around the expansion hinge parts 3 and 4 by the expansion force generated by the steering shaft support part (see FIG. 3), the steering shaft support part 2 supports the expansion. The extension force also acts on the steering shaft 5 that is present, and the steering shaft 5 extends along with the steering surface 1 around the steering shaft hinge portion 7. In the first embodiment, the expanded hinge portion 3 and the expanded hinge portion 4 are brought close to the body 9 to a position where the steering surface 1 can be folded by 90 °.

Next, a second embodiment of the present invention will be described with reference to FIG. The mechanism of the second embodiment is basically the same as the mechanism of the first embodiment. In the second embodiment, the folding angle is 90 ° by scooping out the body portion which the body 9 contacts with the steering surface 1 and the steering shaft support 2 when folding.
Bigger than that.

Next, a third embodiment of the present invention will be described with reference to FIG. The mechanism of the third embodiment is basically the same as the mechanism of the first embodiment. However, in the third embodiment, the body 9 is attached so that the expanded hinge portion is cut out so as not to come out from the outer surface of the body, and the expanded hinge portion is embedded in that portion. Furthermore, by making the steering surface 1 and the steering shaft support portion 2 arcuate, the extensible steering blade can be housed inside the fuselage surface when the steering blade is folded.

Next, a fourth embodiment of the present invention will be described with reference to FIG. The mechanism of the fourth embodiment is basically the same as the mechanism of the first embodiment. In the fourth embodiment, the folding hinge portion is separated from the body 9 so that the folding angle is larger than 90 °.

Although the present invention has been described above based on the illustrated embodiments, it goes without saying that these are merely embodiments and that the structure and shape may be appropriately changed within the scope of the present invention.

[0020]

According to the present invention, the following effects can be obtained.

(1) In the conventional extensible steering blade, since the extensible hinge portion is present in the steering surface, the air flow is disturbed by the extensible hinge portion during steering, and the steering efficiency is reduced. In the steering wing according to the present invention, the expansion hinge portion is removed from the steering surface,
Since it is provided closer to the body than the steering surface, the stretch hinge portion does not disturb the airflow during steering, and steering efficiency is not reduced.

(2) The thickness and length of the steering surface have been increased in order to accommodate the expanded hinge portion, which has been in the steering surface, in the conventional steering surface. This increased the cross-sectional area of the steering surface, which increased air resistance and reduced flight efficiency.
In the steering wing according to the present invention, since the expansion hinge portion is eliminated from the steering surface, the thickness and length of the steering surface can be optimized, and aerodynamic resistance can be kept low and flight efficiency can be kept high.

(3) According to the present invention, since the expanded hinge portion can be provided in the vicinity of the body having a slow air velocity, air resistance due to the expanded hinge portion can be reduced and flight efficiency can be increased. it can.
