Abstract: In this paper, we sum up the achievement resulted from developing a no-zzleless solid propellant rocket motor. We analyse the merits and demerits of a nozzleless motor and compare them with that of a nozzled one.The performance of ignition, combustion, grain deflection and two phase flow inside nozzleless motor are described.Some of the problems in culculating the interior ballistics for nozzleless motor are also discussed.
