Description

Multi-level balloon system {MULTISTAGE BALLOON SYSTEM}

The present invention relates to a balloon system for lifting a carried object such as observation equipment from the ground by using buoyancy, and in particular, a guide connected to lift a propellant balloon and guide the direction in addition to a propellant balloon that directly lifts the carried object by buoyancy. The present invention relates to a multi-stage balloon system equipped with a balloon to allow stable takeoff without expensive and complicated devices and to properly control the altitude during the ascent and return.

Recently, attempts have been made to use a balloon as a propellant to launch a robot or observation equipment in space. NASA, for example, recently developed a super-pressure mechanism capable of 100 days of activity in the stratosphere, and plans to use balloons to collect satellites, space debris. On the other hand, a group of teenagers put a 100,000 won camera on a balloon, and a space photograph was fired around the world.

Meanwhile, at KISTI's 2006 Global Trend Briefing (GTB), Carl Morland, Henry Hallam, Robert Fryers and other students mounted rockets on balloons to launch rockets when they reached their highest levels. He described the experiment of pulling a rocket into a balloon up to 100 km or more. In this regard, Hallam, a test participant, said several balloon trials were planned for several months and that the reliability of the experiment would not be 100%.

The idea of using a balloon as a rocket propellant is not new at all, and in 1949, the famous American space scientist James Van Allen used an instrument called 'rockoon' to lift the rocket up to a high altitude. This is because it is very similar. In the case of the rockoon, it has succeeded several times in experiments to measure the Earth's high magnetic field, but it has failed frequently, and since it lost its direction, there was power that was only operated at sea.

Hereinafter, a propellant balloon according to the prior art will be described with reference to the accompanying drawings.

Figure 1 is a reference diagram for explaining the case of using a propellant balloon of the prior art.

As shown, in the related art, while carrying a large one propellant balloon 10 in the air, the carried object (M) such as observation equipment connected to the connection line 20 could be raised.

According to this prior art, a large volume of the propellant balloon 10 made to have a sufficient force to lift the carried material (M) had to lift the carried object (M) at once and lifted off in a vertical direction. If the propellant balloon 10 does not immediately rise in the vertical direction or moves in the horizontal direction, a deadly result may be caused by the loose connection line 20, in which the carried object M is dragged into an unstable state and overturned or broken. Because.

However, according to the prior art, it is very common that the propulsion balloon 10 is damaged in the take-off stage under the influence of the wind while the carried object M connected to the connection line 20 is damaged. Of course, the trailer carrying the transported material M may be tuned along the moving direction of the propellant balloon 10 so that the transported material M can be vertically taken off by the propellant balloon 10, but it is not sufficient to solve the problem. It was.

As described above, attempts have been made to elevate expensive carried objects (M), such as space observation equipment, to the outer space by utilizing the balloon 10 as a propellant, but the reasons for repeated failures are the carried vehicles (M) and Although the material of the balloon 10 itself has been at the cutting edge due to rapid development of technology, the method of taking off the carried object M by using the balloon 10 is because it does not escape the primitive method.

In addition, in the prior art using a single balloon 10 as a propellant, even if takeoff was made safely, the control according to the altitude during rise or fall is not properly performed, so that the entire system including the expensive carried object M is completely Lost or crashed during landing. Of course, attempts have been made to overcome the problems using expensive and complex equipment, but the results are insignificant compared to the funds invested.

Accordingly, the present invention has been proposed to solve the conventional problems as described above, and an object of the present invention is a guide balloon connected to lift the propellant balloon to guide the direction in addition to the propellant balloon for directly raising the carried object by buoyancy.

Figure 2 is a perspective view of a multi-stage balloon system according to the present invention, Figure 3 is a longitudinal cross-sectional view for explaining the configuration of the multi-stage balloon system according to the present invention.

As shown, the multi-stage balloon system of the present invention guides the takeoff of the propellant balloons 110a, 110b, 110c in addition to the propellant balloons 110a, 110b, 110c for lifting and lifting the carried object (M). The guide balloon 120a for the fall, and the auxiliary guide balloon 130 for controlling the falling speed during the landing and landing is connected in series by the connection line 140 in a basic configuration. The present invention enables stable take-off and ascension without expensive and complicated devices, and appropriate control can be made even during the fall and landing due to the return, so that various types of carried object (M) such as observation equipment can be used for the purpose. It can help you do the work you need and help you return safely afterwards.

Hereinafter, the configuration of the present invention will be described in more detail with respect to each of the above components.

The propellant balloons 110a, 110b, and 110c serve to elevate the carried object M by buoyancy, and are formed in plural stages along one connection line 140. However, although illustrated as being provided with a first stage propellant balloon 110a, a second stage propellant balloon 110b, and a three stage propellant balloon 110c, of course, it may be provided with a greater number as needed.

The propellant balloons 110a, 110b, and 110c have through-holes 115a, 115b, and 115c formed to penetrate the connection line 140 in the center portion for engagement and support with the connection line 140. . Couplers 111a, 111b, and 111c for supporting the propellant balloons 110a, 110b, and 110c by connecting the connection lines 140 are installed in the through holes 115a, 115b and 115c. Wherein the coupler (111a, 111b, 111c) may be provided in a variety of forms, but the outer circumferential surface of the propellant balloon (110a, 110b, 110c) the surface of the propellant balloon (110a, 115b, 115c) made of a lightweight foamed synthetic resin material And to be bonded to, the center may be provided in a simple form having a fitting hole for supporting the connection line 140.

The reason for forming the through-holes 115a, 115b, and 115c in the plurality of propellant balloons 110a, 110b, and 110c to support one connection line 140 is to carry the load of the carried object M. This is to prevent the load is concentrated and damaged only in the first stage propellant balloon (110a) located at the bottom by evenly distributed throughout the balloon (110a, 110b, 110c).

In addition, the propellant balloons 110a, 110b, and 110c are provided with propellant injection nozzles 112a, 112b, and 112c, respectively, to discharge the gas filled therein to the outside. The propellant balloon injection nozzles (112a, 112b, 112c) may be provided with a mechanical type that can automatically discharge the filled gas when the internal pressure of the propellant balloon (110a, 110b, 110c) is a predetermined or more, communication It may be provided in a manner that can be operated remotely from the ground by an additional configuration such as an interface. When the propellant injection nozzles 112a, 112b and 112c are provided, they can be utilized in various ways for stable ascent and return. For example, when the altitude increases in the atmosphere, when the propellant balloons 110a, 110b, and 110c are inflated and the ascending speed is excessive or may burst, the gas filled by the propellant balloon injection nozzles 112a, 112b and 112c is released. can do.

On the other hand, the gas filled in the propellant balloon (110a, 110b, 110c) may be different to at least two or more. This makes it easier to precisely adjust the ascending speed than when using only one type of gas and more freely configure the sizes of the propellant balloons 110a, 110b, and 110c. For reference, in the drawings, the gas G2 filled in the first stage propellant balloon 110a and the gas G1 filled in the second and third stage propellant balloons 110c are illustrated as being different.

In addition, the propellant balloons 110a, 110b, and 110c are not limited to one type of material but may be formed of two or more different materials. Thus, it is possible to save the grave of various operations according to the type of material forming the propellant balloons (110a, 110b, 110c). For example, in the case of the first stage propellant balloon 110a that must withstand the load of the carried object M from the plurality of propellant balloons 110a, 110b, and 110c to the last moment, the two-stage propellant balloon 110b or the three-stage propellant balloon It may be made of a material that is more durable than (110c). The material that can be employed to provide the propellant balloons (110a, 110b, 110c) may be a rubber or special fiber or a material having a considerable characteristic thereof, in the present invention guided by the guide balloon (120a) Metallic materials are also available. For example, magnesium may be produced in a foamable form and then the interior may be treated in a vacuum without filling gas such as hydrogen or helium. For reference, if the structure is in a vacuum and the structure maintains its shape and has a volume, buoyancy may occur.

Furthermore, although not shown in the drawings, at least one of the propellant balloons 110a, 110b, and 110c may be provided as an open balloon having an open bottom, such as a hot air balloon, and must be limited to a closed balloon as shown in the drawing. no reason.

In addition, the propellant balloons 110a, 110b, and 110c may be configured such that a plurality of them are connected in parallel at some stages, which will be described later through a modified embodiment.

The guide balloon (120a) is connected to the upper side of the propellant balloon (110a, 110b, 110c) by the connection line 140 serves to guide the direction of the propellant balloon (110a, 110b, 110c) at take off. Here, it should be noted that the guide balloon 120a does not have enough force to take off the carried object M due to buoyancy, but he himself takes off first and lifts the relatively bulky propellant balloons 110a, 110b and 110c. It also plays a role of presenting direction. To this end, the guide balloon 120a is filled with gas G3 having a relatively small specific gravity compared to the propellant balloons 110a, 110b, and 110c so as to have mobility to start taking off first on the ground, and also to make the volume smaller. desirable.

In addition, the guide balloon 120a may be provided with a guide balloon injection nozzle 122a to discharge the gas filled therein to the outside. The guide balloon injection nozzle 122a may be mechanically provided to automatically discharge the filled gas when the internal pressure of the guide balloon 120a is greater than or equal to a predetermined level. It may be provided in a manner that can be operated remotely. When the guide balloon injection nozzle 122a is provided in this way, it can be utilized in various ways for stable ascent and return. For example, when the altitude is increased and the guide balloon 120a is considered to be in danger of swelling and bursting, the volume of the guide balloon 120a may be reduced by releasing the gas filled by the guide balloon injection nozzle 122a.

In addition, the guide balloon 120a may be made of the same material as the propellant balloons 110a, 110b, and 110c, but preferably, may be formed of a material having a specific gravity smaller than that of the propellant balloons 110a, 110b and 110c. The material that can be employed to provide the guide balloon 120a may be rubber, special fiber, or a material having considerable characteristics thereof, but a thin metal material may be used. For example, magnesium may be produced in a foamable form and then the interior may be treated in a vacuum without filling gas such as hydrogen or helium.

On the other hand, although not shown, the guide balloon 120a may be provided in plural, such as the propellant balloons 110a, 110b, and 110c, and may be connected in multiple stages by the connection line 140. In this case, the guide balloon 120a may be coupled to the connection line 140 by a coupler having a through hole like the propellant balloons 110a, 110b, and 110c except for the one positioned at the top. In addition, it is possible to combine a variety of filling gas and various materials, such as multi-stage propellant balloon (110a, 110b, 110c).

In addition, a plurality of guide balloons 120a may be provided to be connected in parallel, which will be described later through a modified embodiment.

The auxiliary guide balloon 130 is connected to the lower side of the propellant balloon (110a, 110b, 110c) serves to control the falling speed of the propellant balloon (110a, 110b, 110c) when landing or returning. The correct installation position of the auxiliary guide balloon 130 becomes the lower side of the carried object (M) and serves to pull the carried object (M) to the ground against the first stage propellant balloon (110a) that will remain until the last moment of landing on the ground. Will be Therefore, the auxiliary guide balloon 130 is filled with a gas G4 having a specific gravity greater than that of air. In addition, the auxiliary guide balloon 130 is also provided with a spray nozzle 132 for the auxiliary guide balloon. This can be used for the purpose of mitigating the impact on the carried material (M) by reducing the rate of falling by releasing a large specific charge gas immediately before landing.

The connection line 140 serves to connect the multi-stage propellant balloons 110a, 110b, and 110c and the guide balloon 120a, and is provided as one long line. In the middle of the connection line 140, a propellant balloon separating module (150a, 150b) for separating some of the propellant balloons (110a, 110b, 110c) and the guide balloon separation module for separating the guide balloon (120a) 150c is installed. The propellant balloon separation module (150a, 150b) and guide balloon separation module (150c) is basically provided with two bodies that can be combined and separated to the upper side and the lower side, if the remote control method from the ground, these And a controller for controlling the detachment operation of the body and a communication interface for remotely operating the controller from the ground. If the remote control from the ground, not the method of automatically separating according to the altitude, in mind, a sensor for controlling the separation operation of the body according to the sensing sensor, such as barometer for altitude measurement and the sensing sensor It is provided. In addition, the propellant balloon separating modules 150a and 150b and the guide balloon separating module 150c may be simply configured to have a ring shape that is mechanically separated without passing through a controller when a predetermined height is reached.

As described above, the separation module 150a and 150b for the propellant balloon and the separation module 150c for the guide balloon release the multi-stage connection between the propellant balloons 110a, 110b and 110c and disconnect the connection of the guide balloon 120a. It is good to employ various well-known techniques as needed. As such, the separation module 150a and 150b for the propellant balloon and the separation module 150c for the guide balloon are provided so that a part of the propellant balloons 110a, 110b and 110c and the guide balloon 120a can be separated. This makes it possible to safely lift, swim and return the conveyed object M without expensive and complicated devices.

In addition, the auxiliary guide balloon 130 is further provided with a separation module 132 for the auxiliary guide balloon to be detachable in the entire system. In the case of the guide balloon separation module 132, the configuration of the propellant balloon separation modules 150a and 150b or the guide balloon separation module 150c is substantially the same, and thus detailed description thereof will be omitted.

The operation and operation method of the multi-stage balloon system according to the present invention configured as described above will be described in detail with reference to FIGS. 4A to 4H. However, the operation and operation method of the present invention described below is only one limited case, and numerous combinations are possible if the various functions of the present invention are used according to the situation.

First, Figure 4a shows a state taking off the multi-stage balloon system according to the invention from the ground. As shown, in the multi-stage balloon system according to the present invention, a small specific gravity gas is filled in comparison with other propellant balloons 110a, 110b, and 110c, and at the same time, the small-sized guide balloon 120a easily rises even in a weather without wind. While lifting the plurality of propellant balloons (110a, 110b, 110c) in sequence vertically. Accordingly, the three-stage propellant balloon (110c), the two-stage propellant balloon (110b), the first-stage propellant balloon (110a) is taken off and rises sequentially, starting with the guide balloon (120a), after which the propellant balloon (110a, With the force of 110b and 110c, the carried object M such as observation equipment is safely taken off from the ground. Figure 4b shows the multi-stage balloon system according to the present invention immediately after take off from the ground of the ground.

As such, the multi-stage balloon system according to the present invention can lift the bulky propellant balloons (110a, 110b, 110c) in the vertical direction through the guide of the guide balloon (120a), unlike the prior art carried material (M) ), There is no need to move quickly in the direction of the propellant balloon.

Subsequently, as the multi-stage balloon system according to the present invention continuously rises to reach a high altitude as shown in FIG. 4C, the volume of each of the propellant balloons 110a, 110b, and 110c and the guide balloon 120a increases as the external pressure decreases. In the case of the present invention, the propellant balloons 110a, 110b, and 110c are lifted up and taken off by the guide balloons 120a, so that the initial volume of the propellant balloons 110a, 110b, and 110c can be comfortably taken. Therefore, even if the propellant balloon (110a, 110b, 110c) is inflated at a high altitude there is no risk of bursting, but releases the gas filled therein through the injection nozzle for adjusting the ascending speed. Since the injection nozzles are installed in both the propellant balloons 110a, 110b, and 110c and the guide balloon 120a, the ascending speed may be slowed down by releasing the gas filled from some or all of the balloons.

Then, when the height is higher and the role of the guide balloon 120a is no longer needed, the guide balloon 120a is removed from the entire system by operating the separation module 150c for the guide balloon. The ascent rate is then slightly reduced.

Then, when the multi-stage balloon system according to the present invention reaches the target altitude and needs to swim in the horizontal direction without ascending, the three-stage propellant balloon 110c is separated and removed from the entire system. To this end, the propellant balloon separating module 150b installed between the three-stage propellant balloon 110c and the two-stage propellant balloon 110b is operated. In this process, if the entire system is still rising, the gas filled through the injection nozzles 112a and 112b installed in the remaining propellant balloons 110a and 110b can be discharged in a horizontal direction. As a result, the entire system can maintain a constant altitude, the carried material (M) can perform a task that meets the purpose.

Subsequently, when the work carried out by the carried object (M) is completed, the propellant balloon separation module 150a installed between the first stage propellant balloon 110a and the second stage propellant balloon 110b for returning. It is operated to separate and remove the two-stage propellant balloon (110b) from the entire remaining system. Then, only the first stage propellant balloon 110a supporting the carried object M and the auxiliary guide balloon 130 remain in the entire system, and fall by the load of the carried object M and the load of the auxiliary guide balloon 130. To start. In this case, when the gas filled from the first stage propellant balloon 110a is discharged through the propellant balloon injection nozzle 112a, the drop speed may be increased.

Then, when the remaining system is close to the ground area to operate the auxiliary guide balloon injection nozzle 132 as shown in Figure 4g to slow down the falling rate to discharge a portion of the filling gas having a large specific gravity from the auxiliary guide balloon 130. . As a result, the auxiliary guide balloon 130 is lighter, and the falling speed is reduced.

Thereafter, immediately before reaching the ground region, the auxiliary guide balloon 130 is separated from the remaining system by removing the auxiliary guide balloon 130 by operating the separation module 150d for the auxiliary guide balloon as shown in FIG. 4H. The rate of fall then decreases to the point where it can swim horizontally. At this time, by using the injection nozzle (112a) to discharge a small amount of the gas filled from the remaining one-stage propellant balloon (110a) it can be landed lightly without damage to the carried material (M).

As described above, the multi-stage balloon system according to the present invention can be flexibly manipulated as needed throughout the entire process from takeoff to ascending, horizontal swimming, falling, and landing. Therefore, the carried object (M) can support to return safely after performing the purpose at a certain altitude.

Next, the present invention according to the modified embodiment will be described.

5 is a cross-sectional view for explaining the configuration of the present invention according to the first modified embodiment.

As shown, according to the first modified embodiment, two or more propellant balloons may be provided at at least one of the stages in which the propellant balloons 110a, 110b, and 110c are located. However, although the drawing illustrates a plurality of three-stage propellant balloons 110c and thus a plurality of guide balloons 120a are provided, a plurality of single-stage propellant balloons 110a or two-stage propellant balloons 110b may be provided. Of course it can.

As such, when a plurality of three-stage propellant balloons 110c are provided, the separation module 150b-2 provided to separate the three-stage propellant balloons 110c from the system may individually separate each of the plurality of three-stage propellant balloons 110c. It is provided in a modified form that can be separated. Since other components are much the same as before the deformation, a detailed description thereof will be omitted.

As such, when a plurality of propellant balloons 110a, 110b, and 110c are provided at some stages and connected in parallel, buoyancy to raise the carried object M with a greater force can be obtained. Therefore, when the load of the carried object (M) is large, or while applying the same force to raise the carried object (M) while reducing the volume of the propellant balloon (110a, 110b, 110c) is usefully carried out to facilitate takeoff can do.

6 is a cross-sectional view for explaining the configuration of the present invention according to the second modified embodiment.

As shown, according to the second modified embodiment, a plurality of guide balloons 120a are provided to be connected in parallel. As such, when the guide balloon 120a is provided in plural, the separation module 150c-2 for the guide balloon provided to separate the guide balloon 120a from the system may separately separate each of the plurality of guide balloons 120a. It can be provided in a modified form. Since other components are much the same as before the deformation, a detailed description thereof will be omitted.

Thus, according to the configuration provided with a plurality of guide balloons (120a) can lift the propellant balloons (110a, 110b, 110c) with greater force during take-off, so that when the volume and load of the propellant balloons (110a, 110b, 110c) are large It can be useful.

7 and 8 are reference cross-sectional views for explaining the configuration of the present invention according to the third modified embodiment.

As shown in FIG. 7, according to the third modified embodiment, the propellant balloons 110a-2, 110b-2, and 110c-2 are provided as balloons having a general shape without the through holes 115a, 115b and 115c. do. Accordingly, the connection lines 140a, 140b, 140c, and 140d connecting the propellant balloons 110a-2, 110b-2, 110c-2 and the guide balloon 120a are formed at the top and bottom of each section instead of one long line. It is provided with a plurality of short lines connecting the balloons located. Since other components are much the same as before the deformation, a detailed description thereof will be omitted.

This third modified embodiment tends to concentrate the load of the carried object M2 on the first stage propellant balloon 110a-2 as compared to other balloons, so the implementation range is limited only when the load of the carried object M2 is not large. There are disadvantages that are limited, but if the material of the propellant balloons (110a-2, 110b-2, 110c-2) is provided with a strong durability may be alleviated to some extent. On the other hand, the third modified embodiment has the advantage that it can be easily implemented at low cost because it can use the existing balloon as it is, not the tubular.

Meanwhile, in the third modified embodiment, as shown in FIG. 8, only the first stage propellant balloon 110a-2 in which the load of the carried object M2 is concentrated is formed into the tubular propellant balloon 110a having the through hole 115a as before the deformation. A modified configuration is also possible. According to this configuration, the load of the carried object (M2) is distributed to the tubular one-stage propellant balloon (110a) and the general form of the two-stage propellant balloon (110b-2) while improving the problem of the load concentration can be implemented at a low cost. It also has its advantages.

9 is a reference sectional view for explaining the configuration of the present invention according to the fourth modified embodiment.

As shown, according to the fourth modified embodiment, the connection line 140 is provided as a hollow tube to which the fluid F can be transferred. According to this configuration, the lower portion of the connection line 140 extends to the ground region, and in the ground region where the connection line 140 extends, the fluid F is pumped to the air through the connection line 140 to be transported. A pump (P) is provided, and the fluid supply device 180 having a nozzle 181 is installed on the connection line 140. In the drawing, the fluid supply device 180 is shown to be installed at a position between the propellant balloons 110a, 110b, and 110c and the guide balloon 120a, but if the load is large, the fluid supply device 180 is installed below the first stage propellant balloon 110a. It is desirable to take the force of all of the propellant balloons 110a, 110b, 110c during takeoff and ascent (not shown by reference numerals "T" and "171" are fluid storage tanks and underground transport pipes).
