| Abstract: | The paper introduces the shaping method improvement and technological trial course of bottom cap of certain model of carrier rocket's fuel tank. After the primary cap's deficiencies are analysed, the make up method to offset winding spring is put forward. And the flanging method is used to improve the welding quality. According to its characteristics, the author analyses and introduces the course of die design. With a large number of technology trials, reasonable technology parameters are determined. The bottom cap is applied successfully to second stage fuel tank of certain model of carrier rocket. |
