Design, Analysis, manufacture and flight testing of university level Explorer Rocket with Solid propellant motor

A systematic design of the solid propellant rocket; Analysis of characterizes and components; Manufacture of a porotype and flight test are the main purposes of study. In rocket motor design process, the zero and one dimensional interior ballistic flow solution are used. The numerical solution is based on iterative approach for propellant combustion conditions and pressure estimation. Propellant grain geometry, combustion chamber, nozzle, motor bulkhead, joints analysis and sealing are most important subsystems; so the challenge is to develop a model for their convergence. The other highlight of this approach are parts building; make solid propellant and finally assemble the motor. This motor was used for real flight test of the sounding rocket. The experimental data and scientific process have good convergence and its results usable for other engineering research.
