Abstract:

A detailed experimental program was conducted to support an advanced transient flame model for the depressurization extinguishment of composite propellants. The pressure was varied from 20 atm to 90 atm and the initial depressurization rate from 1000 atms to 60.000 atms. Generally, the flame ceases within 0,4 ms to 2 ms after initiating the depressurization and recovers for a second flame with a duration up to 150 ms. The relaxation time of the surface and the pyrolysis of the solid material play an important role for the continuation of the combustion. Author
