Problems solved by technology

[0006] Since most airships currently in the air adopt a soft capsule structure, there are mainly the following problems in the development process: First, the skin material always bears the internal air pressure load required to maintain the shape of the capsule at the working height. The requirement for material strength has not been greatly reduced; secondly, the airship is working at a thin a

Abstract

The invention discloses an airship with an inflating skeleton expanding in air, which comprises an airship body 1, a tail wing 2, a tail thruster 3, a connecting element 7, a payload bay 8, a solar cell panel 9, a nose cone 10, a first auxiliary rope 11, an automatic inflating device 12, a second auxiliary rope 13 and two high-altitude balloons 14. The airship is characterized in that a dimensional element of the airship body 1 is skin 4, a longitudinal element is a rigid skeleton 5, and an annular element is an inflating skeleton 6; the inflating skeleton 6 is connected with the rigid skeleton 5 by the connecting element; and the skin 4 is fixedly connected on the outer surface of a grid formed by the rigid skeleton 5 and the inflating skeleton 6. The invention overcomes the defect that a soft bag in a folding state and a connecting part of a pod and other rigid structures are easily torn by strong wind and vortex in the lifting process.

Description

technical field [0001] The invention relates to an air-deployable airship with an inflatable skeleton, which belongs to the technical field of aerospace. Background technique [0002] In view of the special working altitude environment of the stratospheric airship, that is, the air is thin (about 1 / 14 of the atmospheric density on the ground) and the airflow is stable. Under this environmental condition, the internal and external pressure difference required to maintain the capsule shape and maintain the structural rigidity is It is very large, so the required strength and stiffness of the skin material is not very high. However, during the lift-off process, the hull will be affected by strong winds, eddy currents and other weather factors. Since most stratospheric airships use blimps, it is necessary to maintain a certain pressure difference between the inside and outside of the capsule to meet the conditions of strength and stiffness. Skin tension, which increases the wei...
