Abstract:

The analysis showed that chamber pressure and gas temperature affect duration capability significantly, but throat diameter does not. Thermophysical properties of the flame barrier and heat sink also affect duration, but, by comparison, the effect of variations of thermophysical properties of the insulator and load-bearing member is relatively small. High product of density and heat capacity, and moderately high thermal conductivity, are desirable for the flame barrier and heat sink. The heat transfer analysis indicated that significant increases in nozzle duration capability are possible when properly oriented anisotrpic material is used.
