Soft and hard hybrid airship and control method thereof

Abstract

The invention relates to a soft and hard hybrid airship and a control method thereof. An external capsule is arranged on a hard airship body, an external airbag of the external capsule is communicated with an internal airbag of the hard airship body through a controllable communicating valve; a connecting component capable of folding and unfolding the volume of the external capsule is arranged between the outer side of the external capsule and the hard airship body; when the soft and hard hybrid airship is in use, gas in the internal airbag enters the external airbag through opening the controllable communicating valve, so that the emptying volume of the airship is increased, and enough lifting force is ensured; and through compressing gas in the airship and compressing the gas in the internal gas by using the connecting component, the airship begins to descend as the volume of the airship is reduced. The soft and hard hybrid airship and the control method thereof have the benefits that through additionally hanging the external capsule, the remarkable rise of inside and outside pressure difference of the hard airship body is effectively avoided, so that the safety of the airship is ensured; and through increasing the volume of the external capsule, the air buoyancy is kept, so that the defect that the internal airbag releases helium outwards is overcome.

Description

technical field [0001] The invention relates to a soft-hard hybrid airship and a control method thereof. Background technique [0002] The stratosphere is a general term for the space range from 20 kilometers to 100 kilometers above sea level. The "subspace", "super high altitude" and "high altitude" mentioned by Chinese academic circles also refer to this area. [0003] The stratosphere has different characteristics from ordinary space and aviation space. First of all, its meteorological conditions are better, with no clouds, rain, and atmospheric turbulence. The weather like thunderstorms and lightning is relatively rare, and the operating environment is relatively good. In addition, its altitude is special, and satellites cannot stay at such a low position. On the other hand, the air density is low, and the aircraft must fly at high speed to maintain this altitude. Therefore, compared with satellites and airplanes, stratospheric airship has its unique advantages. Comp...

Problems solved by technology

There are some defects in the use of this inflatable skeleton air-deployable airship, which are as follows: ① In order to lift the airship into the air, two high-altitude balloons need to be used to lift it into the air, and the requirements for the auxiliary rope and the connection with the auxiliary rope are extremely high. Pulling a high-altitude balloon into the air is not conducive to the balance control of the hull and will also cause a large bending moment on the longitudinal structure of the hull; Both need to waste a lot of valuable filling gas and expensive high-altitude balloons; ③ in order to ensure that the airship is suspended at high altitude, a large volume is required, and a large part of the volume must be reduced during the descent to reduce air buoyancy. Release the high-pressure gas in the inflatable frame, and the deformation of the hull cannot be guaranteed
