Embodiment approach

[0044] As the first embodiment of the present invention, the purpose of the present invention is to disclose a large airship, such as figure 2 As shown, it includes: a measurement system for the deformation of a large airship airbag, an airbag 5 and a pod 4 positioned below the airbag 5 .

[0045] Such as image 3As shown, the measurement system includes a base station receiver 3, two or more mobile station receiving integrated machines 6, multiple data cables, multiple power cables, a user terminal and a power management module. The reference station receiver 3 is fixed on the pod 4, preferably at the front of the pod 4, and the fixed position is the reference point C. In this solution, two mobile station receiving integrated machines 6 are taken as an example. In order to realize more accurate measurement, 3, 5 or more mobile station receiving integrated machines 6 can be set. Such as figure 2 As shown, the left and right sides in the figure are the front and rear sides...

Abstract

The invention relates to the technical field of stratospheric airships, and discloses a large airship air bag deformation measuring method, which comprises the following steps that a large airship comprises an air bag and a pod positioned below the air bag; a datum point is arranged on the pod, and more than two measuring points are arranged on the air bag; and continuously receiving the positioning signals of the reference point and the more than two measurement points, and obtaining the position of each measurement point, which is changed relative to the reference point, in two times of measurement, so as to obtain the deformation of the capsule body. According to the scheme, through the change of the relative position of the reference point and the measurement point, the technical problem of large-scale airship airbag deformation measurement is solved, and quantifiable and accurate measurement of the airship airbag deformation is realized.

Description

technical field [0001] The invention relates to the technical field of stratospheric airships, in particular to a method for measuring the airbag deformation of a large airship, a measurement system and the large airship. Background technique [0002] Large airships have a very wide range of military and civilian values, such as missile defense, communications, remote sensing, space observation, and atmospheric measurement. [0003] The airbags of large airships are filled with buoyant gas with a density less than air to generate buoyancy to lift the airship into the air. Such as figure 1 as shown, figure 1 The airship includes an air bag 2 and a helium bag 1, and the airship is lifted into the air by filling the helium bag 1 with helium. During the flight, the airbag will change its shape due to changes in the external environment and its own pressure. Excessive changes in shape will affect the flight performance and safety of the airship. Therefore, it is necessary to ...
