Abstract:

his paper gives the review on some advances made in the research of mechanical properties, burning behaviour and processing technology of solid propellants abroad at present. There have been some available results in predicting theoretically mechanical and rheological properties of solid propellants. In order to reduce cost and increase reliability of processing propellants, there is a great demand for the design and manufacture of continous mixer with high efficiency and safty.The research of thermoplastic elastomers used as a kind of future binder of solid propellants has been noticed more and more by many propellant experts.
