Embodiment Construction

[0028] The present invention will be further described now in conjunction with accompanying drawing.

[0029] Such as figure 1 As shown, the single-capsule / multi-capsule combined stratospheric airship with non-conformal release is composed of multiple functionally independent single-vessels. Therefore, in the following description, the method of the present invention will be described by taking a single capsule as an example. However, the method of the present invention is also applicable to the non-conformal release single-vessel / multi-vessel combination stratospheric airship composed of a plurality of functionally independent single-vessels.

[0030] 1. Stress analysis of single capsule

[0031] In order to better illustrate the method of the present invention, firstly, a force analysis is performed on the capsule. Taking the commonly used pull-net structure of the capsule as an example, the force analysis is done on it. Such as figure 2 As shown, the expanded mesh bla...

Abstract

The invention relates to a non-conformal ascending airship ground restriction launching method. The non-conformal ascending airship ground restriction launching method comprises the following steps: separating a capsule body of an airship into an inflation part and a non-inflation part according to buoyant weight balance requirements of a stratosphere environment and a capsule body capacity needed by allowance; the non-inflation part of the capsule body is bundle-shaped. According to the method provided by the invention, a non-inflation cavity basically has a bundle shape before the airship launches, so that the frontal area of the capsule body is reduced and the aims of reducing a wind load and improving the launching reliability are realized.

Description

technical field [0001] The invention relates to the field of airships, in particular to a ground-bound release method for a non-conformal ascending airship. Background technique [0002] Due to the huge size of the stratospheric airship, it will form a wind load under the action of the ground wind when flying, which will seriously affect the safety of the airship. How to reduce the wind load is the key to the safe release of stratospheric airships. Stratospheric airship capsules mainly have two forms: streamlined and single-vesicle / multi-vesicle combination spherical. The streamlined airship generally adopts a combination of buoyant airbags and airbags in order to maintain its shape, and the buoyancy is adjusted through pressure control. Give full play to the advantage of streamline low resistance. The shape of the buoyancy capsule of the single-vessel / multi-vessel combination airship is a sphere, which emphasizes the utilization rate and the effective use of the strength...
