Steady taking-off and landing method for stratospheric airship provided with taking-off assisting balloon, wide airship body and variable wings

Abstract

The invention provides a steady taking-off and landing method for a stratospheric airship provided with a taking-off assisting balloon, a wide airship body and variable wings. A solar power generation device is laid on the upper portion of the wide airship body of the airship. The folding airship wings are mounted on the two sides of the wide airship body and are each of a framework structure, and solar cells of the solar power generation device are fixedly mounted on the upper portions of the folding airship wings. The folding airship wings can be folded to retract or unfolded flatly. Vector propellers are symmetrically mounted on the two sides and the rear portion of the wide airship body. Inflation or deflation of the wide airship body is completed through a pressure system. The solar power generation device is used for supplying power to the vector propellers, the pressure system, the folding airship wings and a flight control system. The flight control system is electrically connected with the solar power generation device, the vector propellers, the folding airship wings and the pressure system. The solar cells are laid on the airship wings, the laying area is enlarged, light energy is converted into sufficient electric energy to drive the vector propellers, and thus sufficient power is provided for the airship; and meanwhile, the pitching angle of the airship can be controlled, the airship is kept cruising at a certain altitude, and both the controllability and the power are remarkably improved.

Description

technical field [0001] The invention relates to the field of airships, in particular to the field of stratospheric airships. Background technique [0002] At the beginning of the 21st century, stratospheric airships have attracted the attention of major countries, and the application fields of forecasting have been used in civil, police, paramilitary, and military applications. At present, stratospheric airships are mostly used in civilian fields such as marine research, emergency rescue and disaster relief, and urban traffic management. . [0003] The stratospheric airship is a lighter-than-air aerostat that relies on air buoyancy to stay in the air and can be suspended in the upper stratosphere for a long time. It is powered by solar energy and has a propulsion system. It does not rely on airports or runways. It can take off and land vertically, hover over any geographic location, operate at an altitude beyond the scope of air traffic control, and is not affected by bad w...

AI Technical Summary

Problems solved by technology

[0004] However, the current stratospheric airship technology is not very mature. The shape of the airship is mostly a drop-shaped single hull, which leads to the limited laying area of ​​solar power generation devices, and the limited light energy conversion power, which limits the power of the airship. The power of the airship is insufficient. The wind resistance of the lower airship is weak, and the entire airship is very limited in terms of controllability and carrying capacity. However, if we only consider increasing the upper surface area of ​​the airship, the resistance of the airship that is too large will be greater, and the maneuverability will be reduced. Inconvenient and not very practical

[0005] On the other hand, existing stratospheric airships have limited ability to adjust altitude. Generally, when the helium temperature difference is high during the day, they float to about 30,000 meters, and when the helium temperature difference is low at night, they drop to 18,000 to 20,000 meters, and even fall to the troposphere. , when encountering strong winds and being blown off, the airship has no way to control the flight attitude and cruising altitude, the controllability is too poor, and it is easy to cause fatal damage

[0006] Also, the take-off method of the current stratospheric airship adopts the unsteady-state lifting method. When taking off, the airship without inflation is lifted up to the stratosphere before unfolding. This method has many disadvantages. The airship cannot ensure that the solar cells are laid flat on the back of the airship. On the other hand, this take-off method makes the airship unable to pass through the troposphere to reach the stratosphere safely if it encounters a strong wind belt or strong wind.

At present, most stratospheric airships use the self-destruct method when landing, that is, the airship explodes the airbag with pyrotechnics, and then falls in a self-destructive manner. On the one hand, the landing point range is very large and completely random, which greatly reduces the recycling of the airship. rate, on the other hand, this method of falling is seriously damaged to the equipment and the cost is too high
