Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0034] Such as Figure 1 to Figure 2 As shown, a method for manufacturing a "pumpkin ball" type aerostat, the aerostat includes a capsule body, and the capsule body is formed by sequentially docking a plurality of "pumpkin ball" type capsule flaps, and the plurality of The butted sac valve forms an axisymmetric body shape as a whole, the two ends of the sac valve coincide with the central axis of the sac body, the length of the two boundary meridians of the sac valve is L1, and the...

Abstract

The invention relates to a 'pumpkin ball' shaped aerostat and a manufacturing method thereof. By adjustment of a welding process, notches are designed at edges of panels; before splicing of the panels, openings of the panels are welded with patches, then the panels are spliced, and finally end sealing is performed. By the manufacturing method, restrained deformation with high-strength ropes is avoided, a 'pumpkin ball' structure of the aerostat is formed under a pressurizing condition, and accordingly the rope demand quantity is decreased, and a skin stress state under the pressurizing state is simplified.

Description

technical field [0001] The invention relates to a "pumpkin ball" type aerostat and a manufacturing method thereof, belonging to the field of aviation. Background technique [0002] An aerostat refers to an aircraft whose specific gravity is lighter than air and which relies on atmospheric buoyancy to lift into the air. Its performance determines the fixed height, working life and load capacity of the aerostat, while the molding performance of the aerostat is determined by the design method and molding process. [0003] The "pumpkin ball" aerostat is an aerostat made of low-cost thin-film materials, which can greatly reduce the requirements for material strength and reduce the development cost of the aerostat. [0004] At present, the conventional forming process of aerostats at home and abroad is mainly to cut the material into willow leaf-shaped pieces with smooth edges by automatic cutting machine tools, and then combine the planes by hot-melt welding, hot-air welding, hi...
