Application of Titanium and Titanium Alloys in Chinese Aviation Industry

China has achieved world-renowned achievements on the "Road to Space". Since the Long March 1 carrier rocket sent the "Dongfanghong 1" satellite to the scheduled orbit on April 24, 1970, China has launched the Long March series. Titanium is used on the launch vehicle and Shenzhou series spacecraft. For example, the low-temperature TA7ELI titanium alloy gas cylinder used in the liquid hydrogen environment developed by China has been used in the CZ-XX series of launch vehicles; China is also made of BT20 titanium alloy The outer shell and fuel tank shell of the missile; use TC4ELI titanium alloy to make the low-temperature liquid oxygen and liquid hydrogen high-pressure gas cylinders of the launch vehicle.

 

The important titanium metal materials provided by my country's Shenzhou 1-10 spacecraft, including titanium rods, titanium forgings, titanium rings, titanium tubes, titanium plates, etc., contributed to the successful launch of the Shenzhou series, and also contributed to the Dongfanghong satellite and the Long March. Series rockets and series missiles provide key structural materials.

 

The internal structure of the structural materials of each compartment of the manned spacecraft in China is heat-resistant titanium alloy; the thrust structure of the supporting main engine of the orbiter of China's space shuttle is made of titanium alloy. In addition, titanium alloy is also used in the manufacture of rocket planes and missiles Base components, missile power blade sleeves, etc. The TB2 alloy (Ti-3Al-5Mo-5V-8Cr) developed by China was first applied to satellites, satellites and arrows in 1984, and has been used in various types of satellites for more than 20 times. ; TB10 alloy (Ti-3Al-5Mo-5V-2Cr) has been used for forged parts in aerospace structural parts, aircraft fuselage, and wing structures; NINCT20 titanium alloy can not only be used in rocket engine piping systems, but also can be widely used In the aerospace industry, complex-shaped cryogenic piping systems.
