Application of
titanium and titanium alloys in aerospace project began in 1955, the United States of rocket engine shell material widely used titanium alloy. Titanium alloys are widely used in various structure. "the Apollo spacecraft has about 50 pressure vessel, 85% of them were made from titanium. Hercules transition stage engine, using titanium alloy propellant tank after the 35% reduction in weight" Apollo "spacecraft bracket, Fixture and adopt titanium, using 68 tons of titanium. Space engineering also use a lot of pressure vessel in titanium, is the most used
Ti-6Al-4V,
Ti–5Al-2.5Sn. Also use the titanium alloy on the missile warhead. Most of us adopt radiation cooling engine nozzle, the nozzle made of titanium alloy. Part of the United States production of Ti3Al base titanium alloy Ti-21Nb–14Al and Ti-24Al–14Nb–3V-0.5Mo.
Titanium foil has been made into missile tail fins and combustion chamber nozzle seals, etc. The thermal protection system of the United States ultra high speed manned spacecraft USES Ti1100 titanium alloy as heat shield, rocket launch vehicle X-33Using titanium alloy as the material fuselage leeward area heat system. The beta 21 s (Ti-15Mo-3Al-2.7Nb-0.2 Si) has been NASA determined for the national air and space aircraft fuselage and wings siding. High-tech companies in the United States by powder metallurgy method in the production of various missile weapon use of titanium alloy parts. Manufacturing titanium alloy missile shell is made of super molding technology, the propellant tank, etc., not only reduce the weight, and to reduce costs by 30% ~ 40%.
