Large explosive class 1.3 solid .propellant rocket motors utilizing polybutadiene binder, aluminum fuel, and ammonium perchlorate oxidizer are typically considered explosively vlsafell. That is, the required stimulus is so large that motor detonation is extremely unlikely, even when donored by a sizeable high explosive charge. Two large ground cratering events have occurred during recent years ...

Abstract Solid rocket motor(SRM) in the whole life cycle, to withstand temperature, gravity, vibration, ignition shock, axial overload and other loads, directly affect of engine. Based on failure mode, mechanism criteria SRM, this paper elaborates explains relevant test numerical simulation methods that storage SRM method analysis, finds under action individual or compound load, column will pro...

Solid rocket motor flows depend strongly on alumina granulometry, which spreads up with coalescence. Solving droplet sizes in unsteady flows is a modeling and numerical challenge, specially when high loadings generate retrocoupling. As an alternative to Lagrangian approaches, the Eulerian Multi-Fluid model describes polydispersity with size-sorted droplet fluids called sections. A two size mome...
