Application of titanium in the satellite control system

 Satellite control system is to control the satellite in space flight path and attitude, it is a satellite of the brain called. In this system, defend, also uses a titanium alloy.
    (1) Titanium cylinder
     Astm F67 Titanium Foil  gas version in the satellite project application earlier, since these cylinders belong pressure vessels, so the material requirements, in addition to the requirements of Section materials have high strength, high toughness, but also called for inclusion of materials and other defects to be strictly control.
    (2) actuator with titanium tube
    Titanium tube actuator is for satellite attitude control engine fuel delivery pipe, corrosion-resistant material requirements only to fuel the media, but also require pipes to be airtight
Good, and nonporous, and inclusions such as pinholes. Especially on the inner surface of the pipe more stringent requirements, does not allow cracks, pits and other defects, surface scratches may not be greater than 0.03mm. If the inner surface is not smooth, as long as the residual dust or other particles 0.05mm shell size, it could result in clogged pipeline accidents.
    (3) titanium clad steel self-locking valve
    Self-locking valve control other large-capacity communications satellite system, in addition to the requirements of the material has good shear strength, fatigue, impact toughness outside. Also requires weld tightness and corrosion resistance. Given this situation, the design chosen titanium - stainless steel explosion composites, but still need to resolve the connection of dissimilar metals.
