| Abstract: |
| Objective To study effects of ultraviolet radiation on helium permeability of aerostat envelope material. Methods According to the use environment of certain aerostat, a natural aging experiment of the envelope material for 1-3 months was carried out. And the helium permeability of the material was measured with the pressure difference method. Results The relationship between the helium permeability and the natural aging time and the aging factors was obtained. Conclusion The helium permeability of materials aged for one month was slightly higher than that of new materials. There is a rapid rise in the helium permeability during the course of 1-3 months. Ultraviolet radiation increases the helium permeability of material. |
