Embodiment Construction

[0027] Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] Generally speaking, a near-space vehicle includes an airship and a tethered ball, and the tethered ball has a capsule 2 made of a capsule material, such as a flexible and tough capsule material such as skin or fiber fabric.

[0029] refer to Figure 1-4 , the capsule body pressure regulating device of the near-space vehicle of the present invention comprises: a buffer bag 1 that is sealingly connected on the outer wall of the capsule body 2; is located between the capsule body 2 and the buffer bag 1 and communicates with the capsule body 2 and the buffer bag 1 The gas channel 3; the valve 5 arranged in the gas channel 3 for controlling the opening and closing of the gas channel 3; the exhaust fan 6 arranged in the gas channel 3. Through the selective opening and closing of the gas channel 3 by the valve 5, and the selective opening and closing of t...

Abstract

The invention provides a bag body pressure adjusting device for a near space aerocraft. The bag body pressure adjusting device for the near space aerocraft comprises a buffering bag, an air passage, a valve and an extractor fan, wherein the buffering bag is connected to the outer wall of a bag body in a sealed way; the air passage is positioned between the bag body and the buffering bag and used for exerting the bag body to communicate with the buffering bag; the valve is arranged in the air passage and used for controlling the air passage to be opened and closed; and the extractor fan is arranged in the air passage. Meanwhile, the invention further provides and a bag body pressure adjusting method for the near space aerocraft. The invention aims at keeping the difference between inside pressure and the outside pressure of the bag body of the aerocraft at a constant value in case of great diurnal temperature change and eliminating risks of deformation of the aerocraft and mechanical fatigue or breakage of the bag body material.

Description

technical field [0001] The present invention relates to the field of near-space vehicles, and more specifically, to a capsule pressure adjustment device and a capsule pressure adjustment method of a near-space vehicle. Background technique [0002] In the field of space vehicles, a near-space vehicle usually includes an airship and a tethered ball, and the capsule of the tethered ball is filled with gas that provides lift for the aircraft. When the aircraft is flying or staying in the adjacent space, the temperature of the gas inside the aircraft will change greatly due to the alternation of day and night. Problems with mechanical fatigue or breakage. The solution in the prior art is that when the temperature inside the capsule of the space vehicle rises during the daytime, the pressure inside the capsule increases continuously, which requires high structural strength of the capsule material. When it is monitored that the pressure difference between the inside and outside ...
