Abstract

The invention provides an airship support structure formed by a longitudinal support pipe and inclined oval rings through communicated connection, and belongs to the technical field of a stratosphere airship. The airship support structure solves the problems of low carrying efficiency and poor stability of the existing stratosphere airship support structure. The airship support structure comprises a head cone and a tail cone, wherein the head cone and the tail cone are in opposite arrangement; the longitudinal support pipe is arranged between the head cone and the tail cone; a plurality of oval inflating support rings are arranged at the outer side of the longitudinal support pipe in a sleeving way and are in inclined arrangement; and the two sides of each inflating support ring are connected with the longitudinal support pipe through a plurality of pull ropes. The airship support structure is used for supporting the stratosphere airship.

Description

technical field [0001] The invention belongs to the technical field of stratospheric airships, and in particular relates to an airship support structure composed of longitudinal support pipes and inclined elliptical rings through-connected. Background technique [0002] At present, the stratospheric airship is large in size and the working environment is complex. The stratospheric airship will inevitably encounter some unexpected situations during the process of rising from the ground to high altitude and hovering at high altitude. The ovalization of the cross-section will affect the overall stability of the airship, increase the flight resistance, and damage the stratospheric airship to the strong wind or vortex, etc., which will easily cause the local instability of the stratospheric airship, thereby affecting the overall structure of the stratospheric airship. The load of the stratospheric airship is almost entirely borne by the support structure of the stratospheric airs...
