铆接结构的飞机增压座舱的气密面上使用了大量铆钉,一架大型客机上约采用16~20万只.选用适当的方法保证铆缝密封是设计和制造中一个很值得研究的问题.几十年来已发展了多种密封方式,但大都借助于铆件夹层间的弹性充填物来密封.本文介绍一种新型——气密铆钉.通过实践证明,以这种铆钉为主而无需夹层间充填物的气密铆缝既可靠又经济. A large number of rivets are used on the airtight surfaces of cockpit-type aircraft cockpit cockpits, and about 160,000 to 200,000 large passenger aircraft are used.It is a well-deserved problem in the design and manufacture to choose the appropriate method to ensure the riveted seam sealing. For decades, many kinds of sealing methods have been developed, but most of them are sealed by elastic packing between rivets. This paper introduces a new type of airtight rivets, which have been proved to be mainly rivets without interlayer The filling of the airtight rivets both reliable and economical.
