Example Embodiment

[0007] Specific implementation mode 1: Combination Figure 1 ~ Figure 4 To illustrate this embodiment, this embodiment includes a sphere, a suspension cable 10, and a payload 11. The sphere includes a skin 1, a plurality of first inflatable skeletons 2, a plurality of second inflatable skeletons 3, a plurality of crosses 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 weft of the sphere. The skeleton 2 is provided with an air inlet 6. The upper and lower junctions of the first inflatable skeletons 2 are respectively connected through the connecting member 5, and the junction between the first inflatable skeleton 2 and the second inflatable skeleton 3 passes through four 4 is connected, the skin 1 is fixed to the outer surface of the grid formed by the first inflatable skeleton 2 and the second inflatable skele...

Example Embodiment

[0008] Specific implementation manner two: combination image 3 with 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 and the outer side 16 of the second adhesive layer 13 The outer side surface 15 of the first adhesive layer 12 is adhered to the skin 1, and the inner side surface 17 of the second adhesive layer 13 is attached to a plurality of first inflatable skeletons 2 and a plurality of second inflatable skeletons. The outer surface of the frame 3 is bonded. With this setting, the shape-preserving ability is better. The other composition and connection relationship are the same as in the first embodiment.

Example Embodiment

[0009] Specific implementation mode three: combination figure 1 To describe this embodiment, the difference between this embodiment and the first embodiment is that the sphere is further provided with a reinforcing patch 9, and the reinforcing patch 9 is attached to the connection between the suspension cable 10 and the skin 1. This setting avoids damage to the skin and increases the effective load. The other composition and connection relationship 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...
