Application of titanium alloy in self-propelled gun

For the ground forces, its main suppression weapon system is large-caliber self-propelled artillery, its mainstream third generation of large-caliber self-propelled artillery is currently mainly 155M caliber, for example, China's PLA-05 Germany's PZH2000 and Russia's 2S19M1 self-propelled artillery has the advantage of large power and high rate of fire Long range, but its own weight is the biggest disadvantage, because all belong to the caterpillar, so the overall total is above 40T, the structure weight is too large, will have a great impact on the long-range delivery of the weapon and the station maneuvering ability of the self-propelled artillery system released by the American International Forecast Company weapon group market According to the analysis report, it is pointed out that in order to meet the needs of future wars and improve the combat power of self-propelled artillery, the development trend of self-propelled artillery needs to move towards high mobility and lightweight. Based on this, countries in order to solve the current poor mobility of self-propelled artillery in the battlefield is not conducive to strategic delivery At present, the fourth generation self-powered gun system is being actively researched and developed. It is the key to reduce the weight of the structure by adopting light structural material. The specific technical scheme is to transform the muzzle brake of composite barrel. Again, for example, the muzzle system, back is given priority to with high performance of the titanium alloy material, thus may effectively reduce the quality of the artillery ups and downs section, at the same time also can effectively reduce the recoil, so as to achieve weight loss goals as a whole At present, the design scheme has been studied in the United States the line of sight cannon And Russia on the study by the union artillery to effective verification For example, the traditional material of muzzle brake is mainly steel castings, so its weight is very large. In specific use, the gun barrel is even completely deformed by gravity, which will have adverse effects on shooting stability and accuracy The titanium alloy component can achieve a weight reduction of 30% to 40%. With the weight reduction, the influence of gravity deformation on the barrel will also be reduced, thus achieving the goal of improved accuracy and stability.
