[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inflatable moderator, and more particularly, to an inflatable moderator that falls while rotating.

[0002]

2. Description of the Related Art A parachute is generally used as a device for decelerating an object falling in the air. However, when an object is dropped from a flying object flying at a speed close to or higher than the speed of sound, an inflatable deceleration is used. The body is used. This is because, when the parachute is dropped at a high speed, the parachute has a drawback that the umbrella opening property is poor and the impact at the time of the umbrella opening is large, and it is practically impossible to use it.

[0003] As shown in FIG. 3, such an inflatable speed reducer has a bubble fence 2 above a balloon-shaped inflatable body 1.
At the same time, the object 3 to be dropped is suspended from the lower end of the expansion body 1. The expansion body 1 has a structure in which an air intake port 4 is opened at the periphery.

When the above-mentioned inflatable speed reducer is dropped,
During the fall, air flows into the inflatable body 1 from the air intake port 4 so that the suspended object 3 can be decelerated and reach the ground with a small impact.

There are various types of the above-mentioned objects (hereinafter referred to as "hanging objects") 3, and some of them are preferable to fall while rotating. For example, some types of sensors preferably rotate at a constant speed in order to sense the entire circumference at the time of falling at a reduced speed.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to provide an inflatable speed reducer which can be rotated and decelerated and dropped.

[0007] In order to achieve the above purpose, high according to the present invention
An inflatable speed reducer for dropping an object from a rapid flying vehicle expands by taking in air during a fall, and has an inverted conical bottom surface , a closed inflatable speed reducer body, and the inflatable speed reducer. A scoop panel having an air intake port at its lower end for taking in air into the body main body, and a scoop panel protruding outside the inflatable speed reduction band main body, wherein the scoop panel has at least an air flow from below. The inclining surface is inclined so as to guide a part thereof in the lateral direction, and the inclined surface against which the airflow from below collides forms a curved surface such that the upper portion is convex, and the inflatable speed reducer is equally spaced. It is characterized by being attached to the lower surface of the main body.

According to the present invention, since the scoop panel is provided which communicates with the inflatable moderator body and expands and guides at least a part of the airflow from below in the horizontal direction, the lateral direction guided by the scoop panel is provided. The air flow of this applies a force in the rotational direction to the inflatable speed reducer. For this reason, the inflatable speed reducer falls while rotating at the time of falling at a reduced speed. In addition, since the rotation causes the resistance coefficient to increase, there is also an advantage that even a small inflatable speed reducer can reduce a heavy object to a predetermined drop speed without any trouble.

1 is a side view of an inflatable speed reducer according to the present invention, FIG.
FIG. 2 is a bottom view of the inflatable moderator, which has an inflatable moderator main body 1 and an air intake 4 which are expanded by air, as is apparent from FIG. The suspension 3 is attached to the lower end of the inflatable speed reducer body 1.

The speed reducer body 1 according to the embodiment of the present invention comprises an upper surface 11 expanding in a truncated spherical shape and a lower surface 12 having an inverted conical shape. A bubble fence 2 is provided at a boundary between the upper surface 11 and the lower surface 12. It has a structure. The air intake ports 4 are provided at equal intervals on the lower surface 12 of the inflatable speed reducer body 1.

The air intake 4 opens at the lower end of the scoop panel 5 which is inclined on the lower surface 12 in a predetermined oblique direction. That is, in this embodiment, the scoop panel 5 communicates with the air intake port 4 and the inflatable speed reducer main body 1 and has a structure that also serves as the air intake port 4. However, it is clear that the air intake 4 and the scoop panel 5 can be separate. That is, if the structure is made to communicate with the inflatable speed reducer body 1, the scoop panel 5 is expanded as the speed reducer body 1 expands.
Also expands. For this reason, even if it is a separate body, a moment for rotating the expansion type speed reducer is generated.

Further, in this embodiment, the scoop panel 5 is inclined at a constant lateral direction with respect to the falling direction, and the inclined surface 51 is formed to be curved. This slope 5
Obviously, 1 need not be a curved surface, but when converting at least a portion of the airflow from below into the lateral direction,
For efficient conversion, a curved surface is preferable.

In this embodiment, the air intake 4
In addition, four scoop panels 5 are provided, and are provided so as to oppose each other at intervals (45 ° intervals), but the present invention is not limited to this. However, at least the scoop panels 5 are preferably arranged at equal intervals over the entire circumference as in the embodiment. If they are not arranged at equal intervals over the entire circumference, the rotational moment will change at the time of deceleration and fall, making it difficult to rotate at a constant speed.

The lower surface 12 of the inflatable speed reducer body 1 is
In the case of this embodiment, the scoop panel 5 has an inverted conical shape, but by forming the inverted conical shape in this way, the scoop panel 5 can efficiently convert the airflow from below into a rotational moment.

[0015]

When the above-mentioned inflatable moderator with the suspended object 3 suspended at the lower end is dropped, air flows into the inflatable moderator body 1 from the air intake port 4. For this reason, the inflatable speed reducer body expands and reduces the falling speed. At the same time, the scoop panel 5, which is integral with the air intake 4, is inflated by air,
Increase rigidity. Therefore, when the inflatable speed reducer falls at a reduced speed, it receives an airflow from below. Since the scoop panel 5 is provided obliquely to the falling direction, a part of the airflow from below is guided in the lateral direction (FIG. 1).
Therefore, a rotational moment is given to the inflatable speed reducer. For this reason, the inflatable speed reducer drops at a reduced speed while rotating.

[0016]

The inflatable moderator according to the present invention is provided with a scoop panel which expands in communication with the inflatable moderator body and guides at least a part of the airflow from below in the lateral direction. The lateral air flow guided by the inflator will add a rotational moment to the inflatable moderator. For this reason, the inflatable speed reducer falls while rotating at the time of falling at a reduced speed. In addition, since it rotates, the resistance coefficient increases,
There is an advantage that the stability is improved and that even with a small inflatable speed reducer, a heavy object can be decelerated to a predetermined falling speed without any trouble.
