1. The scope of application of titanium in the development of the early aerospace industry
Titanium alloy materials used in aviation and aerospace are called titanium alloy castings, which have a wide range of applications, including some rivets and castings in the joints of objects. In the process of making aircraft, titanium alloy is mainly used in the components of engine compressor components, followed by rocket research and development and some weapon structural parts. In the middle of the 21st century, titanium and its alloys have been widely used in general industrial fields.
2. The innovation of titanium alloy in the aircraft frame
A novel and significant structural material employed in the aerospace sector is titanium alloy. Its specific strength is great, it performs well at extremely low temperatures, and its specific gravity and service temperature falls between those of steel and aluminum. It also has outstanding seawater corrosion resistance. Since the 1960s, the fabrication of significant load-bearing components such bulkheads, beams, and flap sliding rails has relocated from the back fuselage to the middle fuselage, partially replacing structural steel. The production of national defense forces has resulted in an ongoing growth in the use of titanium alloys in military aircraft.
3. Titanium alloy air compressor
When the thrust-to-weight ratio of the aero-engine increases from 4-6 to 8-10, the temperature at the outlet of the compressor will increase accordingly from 200°C to 300°C to 500°C to 600°C. Low-pressure compressor disks and blades must be made of titanium alloys or replaced by titanium alloys to manufacture high-pressure compressor disks and blades, so as to achieve the purpose of reducing the weight of the aircraft structure. Since the 1970s, the amount of titanium alloys used in aero-engines has generally accounted for 20% to 30% of the total weight of the structure and is mainly used to manufacture compressor components, such as forged titanium fans, compressor discs and blades, and cast titanium compressors. Receiver, intermediate receiver, bearing housing, etc.
4. Application of titanium alloy spinning parts
In the field of aerospace, titanium rods, and titanium forgings are used in aerospace vehicle systems not only because titanium alloys have strong structural characteristics and good physical properties, but more importantly, they are characterized by lightweight and precision.
5. Application in gas engine
In the field of aerospace, there is another major application field of titanium alloys, which is the application in the manufacture of aircraft engines. So far, 1/3 of the structural mass of gas turbine engines used in modern aircraft in my country is composed of titanium alloys. However, according to relevant data, it was found that as early as the 1940s and 1950s, some industrially developed countries, such as the United States and the United Kingdom, applied titanium alloy technology to improve the performance of jet engines in the early production of aircraft. Structural components. The earliest titanium alloy engine components were compressor blades, followed by the rapid development of titanium alloy compression discs. Today, the fan blades used in most jet engines are made of new titanium alloys.
6. Application of high-temperature titanium alloy
Due to the strong thermal strength and high specific strength of high-temperature titanium alloys, it has been widely used in aero engines. High-temperature titanium alloys are mainly used in aircraft engines for fans, blades, precision instruments or navigators. The use of titanium alloys to replace the original high-temperature alloys reduces the structural weight of the compressor by 30% to 35%. Over the years, in order to meet the needs of high-performance engines, a sound titanium alloy system has been formed.
