A stratospheric airship

Abstract

The invention discloses a stratospheric airship. Aiming at the alternating characteristics such as a gasbag of the stratospheric airship collapses because the gasbag of the stratospheric airship receiving strong solar radiation on daytime is positioned in an overpressure condition and a nightly meteorological environment suddenly becomes cold when the stratospheric airship flies in air in stratosphere day and night for a long time, and the like, on one hand, when the stratospheric airship is positioned in the overpressure condition, the gasbag material bears a huge tensile load so as to tear and break, on the other hand, when the stratospheric airship is positioned in a low-pressure condition, the stratospheric airship cannot maintain the shape so as to be ineffective due to the gravity of the material, the stratospheric airship disclosed by the invention can well overcome the overpressure and low-pressure alternating conditions of the stratospheric airship caused by the factors such as environment temperature, radiation conditions and the like. The gas pressure action in the gasbag of the stratospheric airship can be regulated, so that the stratospheric airship is positioned in a constant pressure condition.

Description

technical field [0001] The invention relates to the field of aerospace, in particular to a stratospheric airship. Background technique [0002] The altitude of the stratospheric airship is generally between 20 kilometers and 35 kilometers from the earth's surface, and the surrounding atmosphere is very thin. Therefore, in order to meet the needs of the load of the stratospheric airship, the volume of the stratospheric airship is generally very large, and the huge volume also makes the capsule strength very sensitive to the internal pressure load. [0003] Generally speaking, the airspace environment and meteorological conditions of stratospheric airships change alternately with different seasons and day and night solar radiation conditions. If the internal pressure cannot be controlled due to the extremely large pressure load, the capsule body will be in a state of overpressure for a long time, and the capsule skin of the stratospheric airship is prone to damage and failure...

[0003] Generally speaking, the airspace environment and meteorological conditions of stratospheric airships change alternately with different seasons and day and night solar radiation conditions. If the internal pressure cannot be controlled due to the huge pressure load, the capsule body will be in a state of overpressure for a long time, and the skin of the stratospheric airship capsule will be easily damaged and failed; on the other hand, at night when the temperature drops suddenly, the interior The temperature of the gas decreases, the pressure of the gas decreases, and the overall pressure may not be enough to support the gravity of the skin, so that the non-formed failure of the stratospheric airship
