The polymer-gelation gel propellant is considered to be a very prospective gel propellant.The study of its rheological property is of great importance,and is the foundation and key to the application of gel propellant in propulsion technology.In this paper rheological behavior of a polymer-gelation gel propellant is studied experimentally by means of rheometer test and round-pipe flowing test respectively.A rheological model is developed on the basis of experimental measurements and the power law assumption...
