Effect of Nano Combustion Modifier on Combustion Properties of DB and CMDB-propellant [PDF]

Proceedings of the 2nd Annual International Conference on Advanced Material Engineering (AME 2016), 2016
In order to investigate the effects of several nano combustion modifiers (nm-DPT, nm-CB and nm-Al) on the combustion properties of DB/Al-CMDB/RDX-CMDB propellants, the propellant samples were prepared through a solventless extrusion technique. The burning rates of propellants were measured by the strand burner method. The results showed that the nm-DPT

Mechanical behaviors and failure mechanisms of CMDB propellant under wide strain rate tension loading

Journal of Physics: Conference Series, 2023
Abstract Composite modified double-base (CMDB) is a sort of mature propellant with a stable structure and high performance. Its tensile mechanical properties should be considered in the structural integrity design of solid propellant charges. The tensile tests were performed on the CMDB by a quasi-static measurement machine.
