Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly of an aggregate for supporting a soft surface film material of a rigid airship from the inside to retain the shape, and particularly to a nose portion and a stern portion of the airship that have a cone shape. It belongs to the technical field of assembling aggregates.

[0002]

2. Description of the Related Art Generally, in the nose and aft of a rigid airship, a ring-shaped aggregate extending in the circumferential direction at right angles to the length of the airship and a length of the airship orthogonal to the ring-shaped aggregate. An aggregate assembly structure is used that connects curved aggregates extending in a direction.

Conventionally, as a method of assembling aggregates of an airship, for example, a scaffold (total scaffolding) that supports and side-supports the entire aggregate at an assembly site is constructed, and ring-shaped aggregates, curved aggregates, etc. are connected. Is being done.

[0004]

According to the above-described conventional method for assembling aggregates of an airship, when the airship becomes large, the scaffolding of the anti-cone type nose and stern becomes large and complicated. There is a problem.

In particular, in large unmanned airships that fly to the stratosphere, lightweight materials such as CFRP are used as aggregates,
There is a problem in that precise assembly becomes impossible even if the scaffold is enlarged or complicated because it tends to be twisted or distorted due to its own weight or the like.

The present invention has been made in view of the above problems, and an object thereof is to provide a method for assembling aggregates of an airship that can be precisely assembled without increasing the size and complexity of the scaffold. And

[0007]

Means for Solving the Problems In order to solve the above-mentioned problems, an airship aggregate assembly method according to the present invention employs the following means.

That is, in claim 1, a ring-shaped aggregate extending in the circumferential direction orthogonal to the length of the airship, and a curved aggregate orthogonal to the ring-shaped aggregate and extending in the lengthwise direction of the airship. In the method of assembling an aggregate of an airship for connecting, a core material corresponding to an axial centerline extending in the length direction of the airship is arranged vertically, and a ring-shaped aggregate is assembled around the core material in a horizontal plane,
The present invention is characterized in that the support member is radially extended between the core member and the ring-shaped aggregate, and then the curved aggregate is connected to the ring-shaped aggregate.

According to this means, since the ring-shaped aggregate is assembled on a horizontal plane, twisting and distortion at the time of assembling the ring-shaped aggregate can be prevented. The assembled ring-shaped aggregate is
The shape is retained by the support member, and subsequent twisting and distortion are prevented.

According to a second aspect of the present invention, in the method for assembling aggregates for an airship according to the first aspect, the assembled ring-shaped aggregates are sequentially raised along the core material and are spaced from above the core material toward the lower side. It is characterized in that ring-shaped aggregates whose diameters are successively increased are laminated through.

According to this means, a spindle-shaped body spreading downward is formed by the ring-shaped aggregate and the curved aggregate with the core as the center.

Then, the ring-shaped aggregate 2'positioned second from the nose side and the aft side around the second core 1'is assembled in a horizontal plane, and the second core 1'and the ring are assembled. Shaped aggregate 2 '
A support member 3'comprising tex, wire, etc. is radially applied between and with respect to both ring-shaped aggregates 2, 2 ', and between both ring-shaped aggregates 2, 2'. The positioned curved aggregate 4'is connected (see FIG. 1D).

Further, as shown in FIG. 2, in order to increase the rigidity, the supporting members 3, 3 are also provided between the ring-shaped aggregates 2, 2 '.
3'is handed over. It is also possible to configure the ring-shaped aggregates 2 and 2'in three or more stages.

After that, as shown in FIG. 3, the assembled spindle-shaped nose portion A and tail portion B are laid sideways and hung by a crane or the like, and mounted on a scaffold D. This scaffold D
A keel portion C that connects the nose portion A and the tail portion B is mounted in advance on the vehicle. As is clear from FIG. 3, this embodiment is a semi-rigid type.

As shown in FIG. 4, the nose portion A, the aft portion B and the keel portion C mounted on the scaffold D are firmly connected and connected by a reinforcing material E, as shown in FIG.

According to this embodiment, the ring-shaped aggregate 2
Since there is no twist or distortion in the etc., the aggregates of the spindle-shaped nose A and tail B of the airship can be assembled accurately and continuously without increasing the size and complexity of the scaffold. You can

In this embodiment, as shown in FIG.
The support member 3 assembles and connects the ring-shaped aggregates 2 or the ring-shaped aggregates 2 and the curved aggregates 4 with each other, and is a plug-in type connecting tool 5 and the core 1.
It is hung between the ring 6 and the ring 6 which is slidably fitted in. In addition, a suspension type support member 3 ″ is hung between another connecting member 5 and another ring 6 ′ which is slidably fitted to the core material 1.

The core material 1 has a single structure and a relatively high height. Further, an assembly scaffold 7 is built around the core material 1.

According to this embodiment, as shown in FIG. 6, the rings 6 and 6'are raised along the core 1 to immediately set the assembled ring-shaped aggregate 2 at a high position. You can Therefore, as shown in FIGS. 7 and 8, the work of connecting the upper ring-shaped aggregate 2 and the curved aggregate 4 and the work of assembling the lower ring-shaped aggregate 2 and the ring-shaped aggregate 2 ′, the curve The work of connecting the aggregates 4'can be simultaneously advanced, and the work efficiency is improved.
