specific Embodiment approach 1

[0015] Specific implementation mode one: combine Figure 1 to Figure 4 Describe this embodiment. The variable-diameter coordinated synchronous winding variable-configurable valve capsule structure in this embodiment includes a central cylinder 1, a pressure-resistant capsule body 2, a top connection structure 3 with airtightness, and a bottom connection structure with airtightness. 4. Symmetric variable-diameter winding center shaft 5, top drive motor 6, bottom drive motor 8 and multiple tethers 7, the top connection structure 3 with airtightness is arranged in the middle of the upper surface of the pressure-resistant capsule 2, and has airtightness The bottom connection structure 4 is arranged in the middle of the lower surface of the pressure-resistant capsule body 2, the central cylinder 1 is vertically arranged in the pressure-resistant capsule body 2, the upper end of the central cylinder 1 is connected with the top connection structure 3 with airtightness, and the central...

specific Embodiment approach 2

[0019] Specific implementation mode two: combination Figure 5 To illustrate this embodiment, a plurality of reinforcing ribs 9 are evenly distributed on the outer wall of the pressure-resistant capsule body 2 of the variable-diameter coordinated synchronous winding type variable configuration valve sac structure described in this embodiment, and one end of each reinforcing rib 9 is connected to the The top structure 3 with airtightness is connected, and the other end of each reinforcing rib 9 is connected with the bottom structure 4 with airtightness.

[0020] The technical effect of the present embodiment is: such arrangement enhances the overall strength of the pressure-resistant capsule 2 and prevents the pressure-resistant capsule 2 from being damaged or deformed. The cord fabric makes the force between the reinforcing rib 9 and the outer surface of the pressure-resistant capsule body 2 uniformly diverge, avoiding the stress concentration when the reinforcing rib 9 and th...

specific Embodiment approach 3

[0021] Specific implementation mode three: combination figure 1 and figure 2 To illustrate this embodiment, the flexible pressure-resistant capsule 2 of the variable-diameter coordinated synchronous winding variable-configuration valve capsule structure in this embodiment is composed of even-numbered hyperboloid curvature valves.

[0022] The technical effect of this embodiment is: such setting, by reducing the radius of curvature of the film, the bearing capacity of the film can be greatly improved, and the film material of the same thickness and material can withstand greater pressure, effectively enhancing the compression resistance of the valve sac structure ability. Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a variable configuration disc capsule structure and a design method thereof, in particular to a variable diameter coordinated synchronous winding type variable configuration disc capsule structure and a design method thereof. The problem that an existing airship capsule structure is disorderly unfolded in the lift-off period, and is inconveniently rotated back into an airship room after being folded and landing. A top connecting structure having the sealing performance is arranged in the middle of the upper surface of a pressure resistance capsule body, a central cylinder is vertically arranged in the pressure resistance capsule body, the upper end of the central cylinder is connected with the top connecting structure having the sealing performance, the lower end of the central cylinder is connected with a bottom connecting structure having the sealing performance, a symmetrical variable diameter winding central shaft is vertically arranged in the central cylinder, the upper end of the symmetrical variable diameter winding central shaft is connected with a rotating shaft of a top driving motor, and the lower end of the symmetrical variable diameter winding central shaft is connected a bottom driving motor. The variable diameter coordinated synchronous winding type variable configuration disc capsule structure is used in the field of aerospace aerostats.

Description

technical field [0001] The invention relates to a variable-configuration valve sac structure and a design method thereof, in particular to a variable-diameter coordinated synchronous winding variable-configuration valve sac structure and a design method thereof, belonging to the field of aerospace aerostats. Background technique [0002] The airship is a kind of aerostat, which can be used as a stratospheric load platform. During the lift-off process, the volume of the airship capsule gradually increases, rises to a specified height, and relies on air buoyancy to stay in the atmosphere. After the task is completed, in order to make the airship land like a parachute and return to the boat garage, the airship structure needs to be folded, and it has a certain structural shape and buoyancy when landing, so that it is convenient to return to the boat garage. Since the capsule body is made of light and flexible film material with high flexibility, if the controllable deployment a...
