Stratospheric airship and steady-state lifting and cruising method thereof

Abstract

The invention provides a stratospheric airship and a steady-state lifting and cruising method thereof, and belongs to the technical field of aerospace. The stratospheric airship comprises a main air bag and a shape-preserving high-pressure air column arranged in the main air bag, wherein the main air bag is flat, the shape-preserving high-pressure air column is annularly arranged, the annular outer wall of the shape-preserving high-pressure air column makes contact with the inner wall of the main air bag, and the plane where the maximum diameter of the shape-preserving high-pressure air columnis located and the plane where the maximum diameter of the main air bag is located are coplanar. On the ground, helium is filled into the main air bag and the conformal high-pressure air column; a preset pressure difference is formed between the inside and the outside of the conformal high-pressure air column; the main air bag is kept in shape under the supporting effect of the shape-preserving high-pressure air column and is supported by the shape-preserving high-pressure air column in the steady-state ascending or descending process, the original shape cannot be lost, the direction is easyto control when the main air bag encounters strong air flow, the main air bag is prevented from being torn in the strong air flow, and safe ascending and descending and repeated use can be achieved. Meanwhile, helium exchange between the main air bag and the conformal high-pressure air column lays a foundation for stable cruise.

Description

Technical field [0001] The invention belongs to the field of aerospace technology, and specifically relates to a stratospheric airship and its steady-state lifting and cruising method. Background technique [0002] At the beginning of the 21st century, stratospheric airships have attracted the attention of major countries, and their prediction applications are widely used in civilian, police, paramilitary, and military applications. At present, stratospheric airships are mostly used in civilian and military fields such as marine research, emergency rescue, urban traffic management, aerial reconnaissance and early warning. A stratospheric airship is a kind of aerostat that sails at high altitude in the stratosphere. It can be suspended in the high altitude for a long time by relying on air buoyancy. It is powered by solar energy and powered by vector thrusters. It has the ability to not rely on airports or runways. An aerostat that can take off and land vertically and hover over ...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present invention provides a stratospheric airship to solve the technical problems existing in the prior art that the airship cannot maintain its shape, is affected by strong air currents, and cannot take off and land safely during the process of ascent or descent.

[0006] The present invention also provides a steady-state lifting method for the above-mentioned stratospheric airship to solve the technical problem in the prior art that the airship cannot take off and land safely due to the influence of strong air currents during the ascent or descent process

[0007] The present invention also provides a steady-state cruising method for the above-mentioned stratospheric airship, so as to solve the technical problem in the prior art that the airship is affected by the temperature difference of helium when the airship is cruising at high altitude, resulting in bursting capsules
