Large or ultra-large compact hard or semi-hard high-speed large-voyage airship

Abstract

The invention provides a large or ultra-large compact hard or semi-hard high-speed large-voyage airship. The airship comprises an air bag. A nacelle is arranged on the inner side of the bottom of theair bag. A flight control and propelling device is arranged at the rear end of the airship. A power system for driving the airship to advance and driving all devices to work is arranged in the nacelle. The power system is an oxy-hydrogen fuel battery pack. Multiple liquid containing cavities are formed in the nacelle. Water outlets of the power system communicate with the liquid containing cavities. The liquid containing cavities are provided with controllable drainage devices. The air bag is filled with helium gas or mixed gas of helium gas and hydrogen gas. Multiple elastic connecting piecesare arranged in the air bag. Part of a bag body of the air bag is drawn together through the elastic connecting pieces to form a buffer air bag part. Through collection and drainage of water generated by the oxy-hydrogen fuel battery pack, gravity center adjustment and control over the flight height and take-off and landing of the airship are achieved, an auxiliary air bag arranged in an existingairship air bag is saved, and the size and flight resistance of the whole airship can be greatly reduced.

Description

technical field [0001] The invention specifically relates to the field of aircraft, in particular to a large or super-large and compact rigid or semi-rigid high-speed and long-range airship. Background technique [0002] An airship is a type of aircraft that uses a gas lighter than air to provide lift. Airships usually consist of a large, streamlined hull, pods, and propulsion units. The airbag of the hull is filled with a buoyant gas with a density less than air to generate buoyancy to keep the airship floating in the air. The pod is used for people to take and load cargo and various equipment needed to carry the airship. The airship has many uses such as traffic, transportation, entertainment, disaster relief, film and television shooting, and scientific experiments. [0003] However, during the operation of the airship, as the fuel carried by the airship is continuously consumed, the mass of the airship decreases, and the gravity will be less than the buoyancy. If it i...

AI Technical Summary

Problems solved by technology

The auxiliary airbag generally accounts for more than 20% of the volume of the main airbag, which greatly increases the volume of the airship airbag, making the airship weak in wind resistance and high in flight resistance

At the same time, under the same load, the setting of the auxiliary airbag will greatly affect the structure and weight of the airship

With the consumption of fuel in flight, it becomes more and more difficult to control the flying height of the airship by filling the airbag with air, and it also greatly limits the range of the airship

It also consumes a lot of energy to frequently inflate and deflate the auxiliary airbag

Compared with airplanes, airships' slow flight speed is another important flaw of airships
