Airship

Technical Field

The invention relates to the technical field of aerostats, in particular to an airship.

Background

In recent years, with the development of communication technology, operations such as inspection and monitoring of unmanned aerial vehicles are increasing day by day, but compared with airships, both general industrial-grade fixed wing unmanned aerial vehicles and multi-rotor unmanned aerial vehicles have the disadvantages of short cruising time and limited voyage, and the unmanned aerial vehicles have the disadvantages of complex system, more potential faults, frequent taking off and landing and large maintenance workload, so that the application range of the unmanned aerial vehicles is not high.

The aerostat can overcome the defects, and can be roughly divided into a balloon and an airship. The balloon is an unpowered aerostat, the airship is an aerostat with a power device, and due to the existence of the power device and the flight control surface, the flight track and the attitude of the airship can be artificially controlled and adjusted. An airship is called a tethered airship if it is secured to a particular airborne area by tethers.

Depending on the structure of the airship, it can be divided into hard airship and soft airship. The rigid airship is provided with a fixed supporting structure, the supporting structure is internally provided with the air bags, and the supporting structure is utilized to ensure the pneumatic appearance of the airship and is generally used for large airships. The soft airship completely utilizes the inflation and expansion of the air bags to ensure the pneumatic appearance of the airship and is usually used for small airships.

Because the blimp lacks a fixed supporting structure, the arrangement of power equipment and load equipment of the blimp is relatively difficult, an additional connecting component is usually required to be built, and under the condition that the lifting force of the blimp is limited, the additionally built connecting component is difficult to simultaneously meet the requirements of high strength and light weight. Therefore, how to reasonably arrange power equipment and load equipment on the blimp is called a technical problem to be solved urgently.
