Abstract:

The report concerns the extinguishment of composite propellants. The experimental results at 100 bar initial pressure emphasize the importance of the condensed phase properties on the depressurization extinguishment. In all cases of alteration of these properties by the change of binder, the particle size distribution, or the addition of Aluminum, the critical depressurization rate for extinguishment was decreased when going from PBCT to PBAN and to PU, from small particles to bigger ones, and from aluminized to non-aluminezed propellants.
