Aerostat inner sling structure capable of externally adjusting tension

Abstract

The invention discloses an aerostat inner sling structure capable of externally adjusting tension. The structure comprises multiple inner sling inner sections the top ends of which are connected withupper pull rings of an inner curtain cloth at the top of the inside of an air bag; the lower end of each inner sling inner section is connected to a cloth cover upper connector; the structure also comprises a soft telescopic cloth cover with the bottom end being open; the top end of the telescopic cloth cover is clamped by the cloth cover upper connector and a cloth cover lower connector; the cloth cover upper connector is detachably connected with the cloth cover lower connector; one end of each inner sling outer section is connected with the cloth cover lower connector and the other end penetrates out of the bottom of the air bag and is connected with one end of an adjusting device capable of adjusting tightness of the inner slings; the other end of the adjusting device is connected to atypical frame of a hanger, and an opening in the bottom end of the telescopic cloth cover covers a hole formed when the inner sling outer sections penetrate out of the bottom of the air bag and is hermetically connected with the air bag. According to the invention, the length and the tension of each inner sling can be adjusted online in real time.

Description

technical field [0001] The invention belongs to the field of structural configuration design, and in particular relates to an inner sling structure of an aerostat whose tension can be adjusted externally, and is suitable for the connection structure design of an aerostat air bag and a hanger. Background technique [0002] The aerostat is mainly composed of an airbag, a pylon (or a pod), an empennage, a rigging, and a nose cone. In order to disperse the concentrated force of the hanger on the airbag, an inner curtain is usually arranged on the upper part inside the airbag, and connected to the hanger by a plurality of inner slings. The initial length of the inner sling needs to match the theoretical space after the airbag is inflated and saturated and loaded. If it is too long, the load of the hanger cannot be transmitted, and if it is too short, an additional clamping load will be generated on the curtain. At present, the adjustment of the inner sling needs to be completed ...

AI Technical Summary

Problems solved by technology

When the inside of the airbag is filled with helium, the length of the inner sling will not match the theoretical space of the airbag due to the change of the shape of the airbag, resulting in inconsistent tension and inconsistent tension on the inner curtain.

When the airbag is loaded, its theoretical space will further change, and the creep of the length of the inner sling after the load is loaded will also affect its tension. In the actual use process, the tension of the inner sling will not match the theoretical value. Bring excessive local tension and affect the safety of the sphere
