In October 1957, the world's first artificial earth satellite Sputnik1 was successfully launched in Russia, creating a new era of human spaceflight. There are many examples of the application of titanium in aerospace engineering in Russia. Such as "Energy-Blizzard", "Peace-1" , "Progress", "Golden Star", "Moon" spacecraft are widely used titanium and titanium alloy materials, using OT4 alloy sheet to make liquid fuel rocket engine combustion chamber and "Peace-1" docking station docking Parts, engine suspension parts, fuel tanks, pipe joints and brackets, etc. made of OT4-1 alloy. BT5-1 and ПT3B alloys are used to make containers-pressure accumulators and cryogenic liquid storage tanks of supercharging systems, BT5-1 alloy It is also used to manufacture impellers for liquid hydrogen delivery pumps. In addition, TH1 alloys are also used as antennas, push rods, contactors and aerospace shock-absorbing components.
