Research on vibration method measuring technology for gelled propellant viscosity measurement

The principle, composition and measurement method of the gelled propellant viscosi-ty measurement system are introduced in this paper. The principle of the gelled propellant viscosity measurement based on the vibration method is expatiated emphatically. The effect of different installa-tion ways of viscosity meter on the measurement result is verified. The calibration technology of viscosi-ty meter in the field calibration environment is studied in combination with the calibration princi-ple. The measured calibration data is given. The experimental verification result indicates that effective method of reducing the error in the site measurement of gelled propellant viscosity is spot calibration.
