Shulou(Shulou.com)11/24 Report--

CTOnews.com, November 14, according to the Chinese Academy of launch vehicle Technology, recently, the overall Design Department of the Rocket Institute has developed a new generation of aerospace high-strength aluminum alloy fasteners, which are lightweight, high-strength, and high in reliable performance, which can promote the overall upgrading of aerospace fasteners.

Lu Hongli, deputy director of the fastener room of the overall design department of the Rocket Institute, said that this series of fasteners is the first high-strength aluminum alloy fastener product with a strength level of 600MPa in the world, with an international leading level of technology, and can fully replace the carbon steel fasteners for installation and connection of models of instruments, with lighter weight and a weight reduction effect of more than 60%, which greatly improves the lightweight level of fasteners and achieves the "single champion" of aerospace fastener products.

There are hundreds of thousands of fasteners on a rocket. the research and application of the new generation of high-strength aluminum alloy fasteners is of great significance to support the lightweight development of aerospace models.

Shi Yuhong, deputy chief of the overall Design Department, said that high strength is not the end point of fastener development, we want it to be both strong and tough, in addition to optimizing the structural design, the team also established comprehensive mechanical performance indicators of tensile strength, yield strength, section shrinkage, elongation and impact toughness of fasteners, stipulated the upper and lower limits of tensile strength of fasteners, and improved the toughness of a new generation of high-strength aluminum alloy fasteners.

At present, the new generation of fastener products have been applied in aerospace models, and product standards and product systems have been formed, which accumulate strength for the independent innovation and technological leadership of aerospace fasteners in China. In the next step, the Rocket Institute will also explore fasteners with intelligence and information, and further improve the performance of basic mechanical and electrical products represented by fasteners in our country.
