Background

The airship is inflated with gas, such as helium or hydrogen, with specific gravity less than that of air, and lifted by buoyancy, so that energy consumption is low.

The existing airship uses an engine propeller to provide thrust, then adjusts a tail wing to fly, generally uses slope climbing and slope descending for taking off and landing, and generally uses a hovering mode if fixed-point landing is to be realized. In addition, the airship may take off or land in a vertical direction, and in the conventional airship, in order to achieve vertical take-off or landing, it is generally achieved by using a thrust vector device. The thrust vector device of the existing airship mainly has the following two modes: firstly, the engine is connected with the airship structure admittedly, and only the screw verts: the power of the engine drives the propeller through a mechanical transmission device which turns 90 degrees, the whole propeller and a blade rotating plane can be controlled by a thrust vector device to rotate 90 degrees to 120 degrees around the output of the engine in a tilting way, and the turning of the thrust around the airship beam is realized; and secondly, the engine and the propeller integrally tilt.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

Typically, an airship is made up of airbags, empennages, pods, power and propulsion devices, landing gear, flight controls, and the like. The air bags provide buoyancy for the airship, the empennage is used for controlling the flight direction when the airship flies, the power thrust device provides power and thrust for the airship, the nacelle provides space for equipment and personnel to mount and ride, and the landing gear provides hull support for the airship on the ground.

In the above background art, it has been described that the conventional airship realizes vertical takeoff or vertical landing through a thrust vector device, and the specific implementation process is as follows: when vertical takeoff is needed, the thrust vector device enables the tension of the propeller of the airship to tilt upwards by 90 degrees to realize upward thrust, the ascending during flying takeoff is realized, and the tension of the propeller is converted into the forward flight direction after the vertical takeoff is finished; when the airship needs to vertically land, the thrust vector device enables the tension of the propeller to be downward, and the airship is approximately vertically landed. It can be seen that in the process of realizing vertical takeoff or vertical landing through the thrust vector device, the propeller needs to be inclined, and the control is difficult.

In addition, the two thrust vector devices provided in the background art generally have the problems of large rotational inertia, complex system and limited use.

Although some airships are proposed to have a plurality of thrust vectors distributed on each part of a hull in the concept research, the problems of complex installation and complex control generally exist.

The solution provided by the present invention is explained in detail below by means of several specific embodiments. The following specific embodiments of the present invention may be combined, and the same or similar concepts or processes may not be described in detail in some embodiments.
