An inner sling structure of aerostat with externally adjustable tension

Abstract

The invention discloses an inner sling structure of an aerostat whose tension can be adjusted externally. The upper joint of the cloth cover also includes a soft telescopic cloth cover with an open bottom. The top of the telescopic cloth cover is clamped by the upper joint of the cloth cover and the lower joint of the cloth cover. The upper joint of the cloth cover and the lower joint of the cloth cover are detachably connected. The outer section of the inner sling One end is connected to the lower joint of the cloth cover, and the other end passes through the bottom of the airbag and is connected to one end of the adjusting device that can adjust the tightness of the inner sling. The other end of the adjusting device is connected to the typical frame of the hanger. The hole formed when the outer section of the sling passes through the bottom of the air bag covers and is sealingly connected with the air bag. The inner sling structure of the aerostat of the present invention can realize real-time online adjustment of the length and tension of each inner sling.

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
