A bionic retractable airship and its coordinated control method

Abstract

The invention discloses a bionic telescopic airship. The bionic telescopic airship is composed of a head cabin, a tail cabin and multiple middle cabins arranged between the head cabin and the tail cabin. Each middle cabin is provided with two radial connecting rings which are the root connecting ring and the end connecting ring respectively. The radial connecting rings of every two adjacent middle cabins are shared. The radial connecting rings close to the outer sides of the two middle cabins close to the head cabin and the tail cabin are a root connecting ring of the head cabin and a root connecting ring of the tail cabin respectively. Each cabin further comprises an active telescopic longitudinal shaft combination and an auxiliary telescopic leather bag combination. The active telescopic longitudinal shaft combinations are used for driving the radial connecting rings of each cabin to axially move to achieve longitudinal telescopic motion of the whole airship. The auxiliary telescopic leather bag combinations synchronously conduct telescopic motion along with the radial connecting rings under dive of the active telescopic longitudinal shaft combinations. The bionic telescopic airship can achieve the volume change within a wide range in the ascending and descending processes, and the work requirement of a stratosphere can be met. The invention further provides a coordination control method based on the bionic telescopic airship.

Description

technical field [0001] The invention relates to a bionic retractable airship and a coordinated control method based on the bionic retractable airship, which belongs to the technical field of airships. Background technique [0002] The airship is filled with gas less than the specific gravity of air through the hull or airbags, and is lifted into the air by buoyancy. The airship can stay at any height in the air for a long time according to the mission, consumes less energy, and can conveniently adopt new energy means to solve the problem of long-term blanking and meet the energy consumption of modern equipment. It is relatively easy to implement The functions of the floating platform, such as: air patrol, survey, search and rescue, aerial photography, air communication, air early warning, air monitoring, stay in the outer layer of orbital space, realize the round trip between the ground-space station-orbit, and realize the A new delivery solution that provides a safe way fo...

AI Technical Summary

Problems solved by technology

[0003] Although the airship has the above advantages in its application, there are still many disadvantages in the existing airship: the hull volume of the existing conformal airship is large, the flight speed is low, and the balance and stability control is relatively difficult

[0004] For example, the United States Jet Propulsion Laboratory proposed a lantern variant airship in 2006 for Venus exploration (Radioisotope Power Systems for In-situ Exploration of Titan and Venus, 4th International Planetary Probe Workshop, California 2006; Venus MobileExplorer with RPS for active cooling-A feasibility study, 2006 Venus EntryProbe Workshop,ESA), but its overall volume change ratio is limited, especially its shape determines the poor aerodynamic characteristics

The Chinese invention patent "variable aerospace airship" (patent number: ZL 200510090070.1) proposes a radial variant airship. If it is not fully deployed, its aerodynamic characteristics are also poor, and its internal volume can only vary from 6 to 8 times, cannot meet the requirement of 14 times volume change required for the target altitude of the high-altitude airship above 20 kilometers above sea level, and the radial stretching process may bring great difficulty to the laying of solar cells

In the paper "A Mechanism Analysis of the Flying and Recovery Process of an Adaptive Variant Airship" (published at the China Mechanics Conference in 2013), the inventor studied a vertical and horizontal linkage variant airship and considered the geometric constraints of the volume change ratio, but this The vertical and horizontal linkage variant airship has no relatively fixed outer surface, which is not suitable for flexible installation of equipment and loads, and may not be conducive to the installation of solar cells due to the wear of the outer surface
