Due to the special requirements of space vehicles in reducing structural weight and improving structural efficiency, the aerospace and aerospace industries have always been the main targets for the promotion and application of titanium alloys. Especially in the early days of the development of titanium flanges, that is, in the 1950s, almost all titanium flanges were used to manufacture aviation aircraft. Only from the 1960s did it gradually expand to the petroleum, chemical, shipbuilding, power station, and other sectors. Even today, it can still be said that the development of aerospace and aerospace technology is the basic factor that promotes the advancement of titanium flanges. In turn, the emergence of new materials will also help the development and application of new aircraft.
Due to the performance characteristics of titanium flanges, it is preferentially used in aviation engines. It replaces aluminum flanges and some stainless steel and high-strength steels to make the main components of compressors, such as compressor rotor blades, disks, stator blades, and casings. Reduce structural weight and increase the weight-to-weight ratio. For example, the Soviet Union was equipped with a MiG-2l engine P11-300 in the early days, and its compressor was mainly a steel structure, while the latter improved P13-300 engine (equipped with MiG-21MF), it used a titanium compressor to make the thrust-to-weight ratio (The ratio of the thrust generated by the engine to the gravity of the perturbation engine) was increased from 5.38 to 5.83. In the 1970s, the Soviet-made P29-300 engine (equipped with MiG-23S) further increased the amount of titanium, so that the thrust-to-weight ratio reached 6.5. At present, the amount of titanium flanges used in aero engines has stabilized between 15-30%.
In terms of aircraft bodies, the application of titanium flanges was a little later. In the early days, it was mainly used to manufacture non-stressed components, such as heat shields and firewalls for the rear fuselage, but it quickly expanded to hydraulic components such as various joints and bulkheads. , Beams, landing gear, etc.
