Abstract: Sedimentation properties, their regularity and relationship with the size of motors for copper-sintered-wolfram nozzles upon sustained flights in SRM are studied. Changes in nozzle throat’s dimension caused by sedimentation are found out. It matches with the experimental results very well and may present as a reference in the design of similar motors.

Key words: SRM , sustained SRM , copper-sintered-wolfram material , sediment layer
