Solid composite propellants often contain metal particles, such as aluminum and the internal flow field in a solid rocket motor is typical gas–solid two-phase field. In this study, to address problem of erosion particles on wall during working process an engine, particle model was established based interaction mechanism between wall. From perspective dynamics, moving analyzed. The force surface...

Typical solid rocket motors (SRM) have advantage of their inherent simplicity and reliability, but they do not have the capability to change thrust profile like other propulsion system. Pintle technology is one of the means to achieve variable and programmable thrust. This paper describes a study of the static and dynamic characteristics of a pintle nozzle under the constant mass flow rate. The...
