Description

Airship

Technical Field

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

Background

Airship belongs to one type of aircraft, and lifting power is provided for the airship by filling an air bag with gas lighter than air. Airships are generally composed of a large streamlined hull, a cargo compartment located below the hull, and propulsion means. The air bag of the airship body is filled with buoyancy gas with density smaller than that of air so as to generate buoyancy force to lift the airship off. The freight cabin is used for passengers to ride and load cargoes. The airship has various uses such as traffic, transportation, entertainment, advertisement, disaster relief, video shooting, scientific experiments and the like.

The prior art airship has the following disadvantages, so that further applications of the airship are limited. Firstly, the airship is usually provided with lifting power by filling a single-layer air bag with lighter-than-air gas, the single-layer air bag has no remedial measure in terms of leakage prevention, and once the air bag leaks, the airship needs to be immediately landed; and secondly, the airship uses the fan taking the fuel oil as a power source as pushing power, the fuel oil not only can increase the load of the airship, but also can break the gravity balance of the airship during take-off along with the increase of the sailing distance after the fuel oil is continuously consumed, and the gravity balance adjustment and supplement are needed along with the fuel oil, so that the control complexity is increased, and the flying stability of the airship is also deteriorated. Third, existing airships are usually realized by increasing the volume of an air bag in order to have large capacity, but the airship with huge size has huge construction, maintenance and use costs and lacks flexibility in use. Fourth, the manned cabin and cargo cabin of the existing airship are all externally hung, so that the flight resistance of the airship is increased, and the volume of the externally hung cabin is limited due to the limitation of externally hanging, so that the carrying capacity of the externally hung cabin is influenced. The pod also creates various difficulties and uncertainties in landing the airship.

Although the existing air transportation, sea transportation, railway transportation and road transportation are developed and mature, the high cost of the air transportation, the long period of the sea transportation, the requirement and dependence of the land transportation on the traffic infrastructure and the like cause the above transportation systems to have own defects and limitations. The novel airship comprises a ship body, wherein the ship body is arranged in the ship body in a streamline manner, the space of the ship body is kept to be beneficial to flying, the space of the ship body can be flexibly changed, the novel airship has the rapid air transportation and the low cost of sea transportation, does not depend on the transportation mode of ground traffic infrastructures such as highways, railways and the like, and can become a new strength of a transportation market to promote the transportation industry.
