摘要

目的研究紫外辐射作用对浮空器蒙皮材料透氦率的影响。方法根据某型号浮空器的使用环境,对其蒙皮材料进行1~3个月的自然老化实验,并用压差法透气性测试仪器测量新材料和老化后材料的透氦率。结果得到了透氦率和自然老化时间及老化因素的关系。结论老化1个月材料的透氦率略高于新材料,而在老化1~3个月过程中,透氦率有一个快速上升的过程。紫外线照射会使蒙皮材料的透氦率上升。
        Objective To study effects of ultraviolet radiation on helium permeability of aerostat envelope material. MethodsAccording 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.
