Abstract:
Throush the theoretical analysis of non—Newtonian fluid．it is concluded that tIle flow characteristic of gelled propellant in the pipeline mainly depending on its own characteristics．There exists distinct difference between the calculation method of the pressure loss of gelled propellant and that of liquid propellant．This paper adopts the Allometric，polynomial and linear equations to perform the curve fitting and comparative analysis on the pressure versus flux test data of gelled N204 and UDMH，which reflects the non-Newtonian fluid characteristic of gelled propellant．Some suggestions to establish a system have been put forward．It is proposed that real medium should be used to carry out the cold conditioning prior to the test of gel test system．The feasible fitting method is also provided for system adjustment data in this paper．
