A gas bottle is a spherical pressure vessel used in aerospace application. A typical gas bottle used in the liquid propulsion system of launch vehicle is considered for the present study. The design is carried out considering two materials namely- Ti - 6Al -4V alloy and Inconel 718. Design is validated through analytical and finite element analysis for specified load. Design is also validated for the different size of crack through fracture mechanics module in ANSYS workbench 18.0. Stress Intensity Factor was determined using analytical method and finite element method for various crack size. Three dimensional analysis of gas bottle in presence of crack is carried out. Stress Intensity factors are compared with the fracture toughness value of the respective materials.
