Development of Aircraft Engine Fasteners in the Future

Hits:Updated:2017-08-03 10:08:48【Print】

Aero engines because of its industrial technology requirements and high known as the "crown of the pearl." Among them, the aircraft engine fasteners as a "Pearl" in the body of the link, but also because of its high pressure, high temperature, high strength of the use of environmental requirements, making its performance and technical requirements relative to other fasteners in terms of more special, High security and reliability. Therefore, the United States, Britain and other technology powers have the aircraft engine fasteners as a basic science, invested a lot of money for research and development. The field of domestic aviation, with the two major projects of the implementation of the ground, officially opened the aircraft engine specialized development of the road for the follow-up of professional and technical development and basic disciplines to create a better development conditions.
 
Status of domestic aviation fasteners
Aircraft engine on the main fasteners products are various types of bolts, with key screw pile, self-locking nuts, screw sets, pins, pipe fittings, and so on. Relative to the fastener large family, the use of fasteners on the aero engine types are more concentrated, but because of its working environment constraints, such fasteners, especially hot-end fasteners use performance requirements are higher.
Domestic aero engine fasteners manufacturers many, mainly scattered in the aviation, aerospace and some private enterprises, the manufacturers are independent of each other, overlapping products, mainly in manufacturing-based, no research and manufacturing base. Most of the domestic aero-engine parts companies belong to the molecular companies engaged in the production of fasteners and small and medium parts by the aeroengine main plant. The technological level of the manufacturers, the technical status management level, and the test capability are uneven. The formation of a set of research and manufacturing of specialized production base, is not conducive to the development of aviation fasteners technology research and development.
