Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing high-altitude balloons have poor rigidity under low internal pressure, the shape will change with the change of wind force, and the shape-retaining ability is poor, so that the high-altitude balloons cannot achieve fixed-point suspension, and then provide a conformal high altitude balloon

specific Embodiment approach 1

[0007] Specific implementation mode one: combine Figure 1 ~ Figure 4 Describe this embodiment, this embodiment comprises sphere, suspension cable 10 and payload 11, and described sphere comprises skin 1, a plurality of first inflatable skeletons 2, a plurality of second inflatable skeletons 3, a plurality of four-way 4, two A connecting piece 5 and a plurality of connecting pieces 7, a plurality of second inflatable skeletons 3 are arranged on each warp of the sphere, and a plurality of first inflatable skeletons 2 are arranged on each latitude of the sphere, and the first inflatable skeleton 2 is arranged on each latitude of the sphere. Air intake holes 6 are opened on the skeleton 2, and the upper junctions and lower junctions of a plurality of first inflatable skeletons 2 are respectively communicated through connecting pieces 5, and the junctions between the first inflatable skeleton 2 and the second inflatable skeleton 3 pass through four 4 communicates, the skin 1 is fi...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination image 3 and Figure 4 To illustrate this embodiment, the connector 7 of this embodiment is composed of a first adhesive layer 12 and a second adhesive layer 13, the inner side 14 of the first adhesive layer 12 is connected to the outer side 16 of the second adhesive layer 13 The outer surface 15 of the first adhesive layer 12 is bonded to the skin 1, and the inner surface 17 of the second adhesive layer 13 is bonded to a plurality of first inflatable skeletons 2 and a plurality of second inflatable skeletons. The outer surfaces of the skeleton 3 are bonded together. With such a setting, the shape retention ability is better. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0009] Specific implementation mode three: combination figure 1 This embodiment is described. The difference between this embodiment and the first embodiment is that the sphere is further provided with a reinforcement patch 9 , and the reinforcement patch 9 is pasted at the joint between the suspension cable 10 and the skin 1 . Such setting avoids damage to the skin and increases the payload. Other compositions and connections are the same as in the first embodiment.

Abstract

A form-preserving high-altitude balloon relates to a high-altitude balloon and aims at solving the defects of the existing high-altitude balloon that the rigid under the low internal-pressure is low; and the form alters along the changing of wind and then the form-preserving capability is poor so that the located floating of the high-altitude balloon cannot be realized. An air intake (6) is arranged on a first charging framework (2) of the form-preserving high-altitude balloon and the upper borders and the lower borders of a plurality of first charging frameworks (2) are communicated respectively through a communicator (5); the first charging framework is communicated with the border of a second charging framework (3) through a four-way (4); a skin (1) is fixed on to a network surface formed by the first charging framework (2) and the second charging framework (3); and one end of a suspension cable (10) is fixedly connected with the skin (1) and the other end of the suspension cable (10) is fixedly connected with an effective load (11). The form-preserving high-altitude balloon is provided with the better rigid and can resist the distortion caused by wind; and the form-preserving capability is better and the located floating of the high-altitude balloon can be realized. The form-preserving high-altitude balloon reduces the requirement on the skin materials so as to reduce the cost and the balloon can bear the heavier effective load.

Description

technical field [0001] The invention relates to a high-altitude balloon and belongs to the technical field of high-altitude detection tools. Background technique [0002] Modern high-altitude balloon is a high-altitude detection tool developed with the progress of space science. High-altitude balloons are unpowered aircraft flying at stratospheric heights (stratospheric heights are 30-40km). High-altitude balloons have the characteristics of high flying height, low cost, short preparation period, and easy and flexible implementation that other aircraft do not have. Some developed countries in the world have started to develop high-altitude balloon technology on a large scale since the 1960s and 1970s, making balloons a detection tool for atmospheric and space science research that keeps pace with aircraft such as rockets and artificial satellites. The skin material of the existing high-altitude balloon is ultra-thin and flexible material, the internal air pressure of the hi...
