Recently, the high-strength gear groove 120Â° countersunk bolt and gear groove 150Â° countersunk bolt standard parts developed by Aerospace Seiko Guizhou Company passed the assessment of AVIC experts. The high-strength gear slot bolts reviewed in this review are designed with the new material PH13-8Mo, which has a tensile strength of 1515 MPa. The Guizhou company adopted a new process technology for the new materials. After two months, it solved the technical difficulties and solidified the process, which made the production of the products successful in a short time. It is currently used for the first time on domestic aircraft models. Through the quality and installation review, the project not only satisfies the overall R&D progress requirements of China's new fighter models, but also contributes to the model product support, and at the same time marks the level of product development of Aerospace Seiko to a certain height, filling the gap of domestic related products. It also laid a solid technical foundation for Aerospace Seiko to expand the high-end product market.
In this review, 26 experts from AVIC 301, 611, Chengfei, Aerospace Henan, Guizhou and the military representative offices of Chengfei Company formed a review team to review the products. (Text / Xie Renjun)
