Abstract: The field calibration of gelled propellant viscometer device for the liquid rocket engine is studied. The mechanical design and installation method of the gelled soakings filling device based on the vibration method is also described. The field calibration process flow of the online viscometer used for liquid rocket engine gelled propellant is emphasized. The pressure/temperature -viscosity data and regulation of gelled propellant were obtained by the test. The uncertainty degree of field calibration system is determined.
