Bag body telescopic stratospheric airship

Abstract

The invention discloses a bag body telescopic stratospheric airship. In order to enable an airship to lift up into a stratosphere, a telescopic inner air bag, a telescopic outer air bag, and a principle that the pressure between the inner air bag and the outer air bag is balanced are adopted; when the airship flies into the stratosphere from the ground, the telescopic inner air bag and the telescopic outer air bag can be expanded to required volumes along with the continuous reduction of external ambient pressure; when the airship returns to the ground from the stratosphere, the telescopic inner air bag and the telescopic outer air bag can be reduced to the original volumes along with the continuous increase of the external ambient pressure, so that the appearance and the safety of the airship can be guaranteed; meanwhile, the hang time of the airship is prolonged by times.

Description

Technical field [0001] The invention relates to a stratospheric airship. Background technique [0002] Stratospheric airships are different from airplanes flying in the aviation layer, traditional airships flying at low altitudes, and satellites flying in low orbits. The specific area needed is an ideal aerospace vehicle platform integrating high-altitude reconnaissance, monitoring and communication. Due to the special purpose of the stratospheric airship, especially military use, its economic value, military value and social value are highly valued by the military of various countries. , businesses and the scientific community. Now, although the "products", pictures and papers reported by various media about stratospheric airships are overwhelming, so far, no real practical stratospheric airship has been seen to fly into the stratosphere by power. At present, most people design stratospheric airships according to the principles and structures of traditional airships, and ...

Problems solved by technology

[0003] 1. According to the traditional airship structure design, it is difficult for the "stratospheric airship" to fly into the 20Km stratosphere

[0004] The traditional airship has a huge auxiliary airbag, which is filled with air. When the airship flies into the 20Km stratosphere, the atmospheric density is only about 7% of that of the ground, and the volume of helium in the airship will expand by about 14 times. The huge auxiliary airbag of the traditional airship The air is difficult to discharge during the lift-off process. If the air is not discharged, the weight of the air will become the load of the airship. This huge load makes it difficult for the airship to fly into the 20Km stratosphere

[0005] 2. Assuming that the traditional airship can fly to the 20Km high-altitude stratosphere, due to the large capsule body, there is little helium in it, and the permeability of helium is very high, and the leakage of helium is very fast, so that the large airship stays in the sky for a short time. To go down to the surface to replenish the helium, not only will the maintenance and operation costs be high, but the life of the bladder will be very short
