A useful technique which is used recently for improving the properties of liquid oxidizer is gellatioin. In the present research it is attempted to study the rheological properties of different IRFNA gels build with different amount of fumed silica as gallant. Rheological measurement indicate that the gels have desirable properties needed for a gel propulsion system like shear-thinning, hysteresis and thixotropy. Rheological measurement were in good agreement with power law model. The flow behavior index (n) was in the range of 0.1 to 0.2 and was insensitive against variation of temperature and gallant percentage, while consistency index (K) was in the range of 0.9 to 352 and varied significantly with variation of gallant percentage and temperature.
