Abstract:
The high filling accuracy of rocket propellant is an important guarantee for the success of the rocket launch.
In view of the factors that affect filling accuracy of the rocket propellant in the filling system of the
spaceflight launch site, the algorithm of propellant filling accuracy calculation based on the flowmeter
measuring model is proposed in this paper. It respectively carries through mathematical analyses for the
different factors affecting the filling accuracy. Through the proposed algorithm, numerical calculation has
been carried on the comprehensive filling accuracy of rocket propellant under the existing filling process. It
can provide theoretical basis and data support for optimizing filling control process and improving filling
accuracy in the launch site, so as to further improving the success rate of rocket launch.
