Abstract:
For the development of UDMH/NTO bipropellant gelled thruster, theoretical analysis, numerical simulation and experimental methods are used to investigate the gelled rheological characteristics. According to the experimental results of the gelled rheological characteristics, the parameters of the gelled rheological characteristics were deduced by the least squares fit. The influence of the cone passageway's taper angle on the rheological characteristics was analyzed by means of numerical simulation. An experimental bipropellant gelled thruster was designed and its hot test of flow property was finished. The experimental results show that the rheological characteristics of the two propellants are similar. As for UDMH/NTO gelled propellant, the optimal cone angle was confirmed, which can make the average apparent viscosity of the gelled at its outlet to reach to minimum. The simulation results of the flow characteristics of the experimental injector are
