Development of spherical cases for the solid propellant rocket motors is presented. These motor cases, made of titanium alloy, have been designed for upper stages of satellite launchers for scientific satellites. In past twenty years, many type of motor cases have been developed corresponding to the ever increasing mission requirement of the Japanese scientific satellites, thereby, overcoming the shortage of budget. In this report, research work carried out to produce more efficient and more large motor cases are outlined, emphasizing the improvement both in material property and manufacturing process.
