Fracture energies of composite propellants

Journal of Applied Polymer Science, 1977
Three types of fracture energies, i.e., for initiation, propagation, and the work of fracture, were measured for an ammonium perchlorate/polybutadiene composite propellant. The testing employed the “trouser leg” specimen configuration. The effect of an accelerated again process on these energy values was also investigated, showing that such a process ...

Modelling of composite propellant properties

36th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 2000
State-of-the-art composite propellants are based on solid particles (AP, Aluminium) in a polymeric HTPB based binder system. The usability of a propellant for a particular application is dependent on a large number of properties. These different properties sometimes result in contradictory requirements and design trade-off need to be made.

Simulation of Composite Propellant Aging

Polymer-Plastics Technology and Engineering, 1993
Abstract Inert polyurethane (PU)-glass elastomeric composites were fabricated to simulate the mechanical behavior of composite propellant systems. A polyether PU system was used in conjunction with 60 wt%, 20 μm glass beads. The mechanical and interfacial properties of model systems were evaluated as a function of time and temperature, using Instron ...

Modelling of Composite-Propellant Flames

2001
Abstract : We examined small deviations from axial symmetry in a solid-propellant rocket motor, and describe a 'bath-tub-vortex' effect, in which substantial axial vorticity is generated in a neighborhood of the chamber centerline. The unperturbed flow field is essentially inviscid at modest Reynolds numbers, even at the chamber walls, as has long been
