Abstract

The propellant sloshing is a significant factor for the design of rocket structure and control system. In order to solve the propellant sloshing problems in ellipsoid cylindrical tank, an equivalent model is established based on the sloshing model of cylindrical tank. The equivalent modeling criterions are proposed according to the sloshing characteristic parameters. And then the equivalent formulas are deduced based on the ellipsoid cylindrical tank model and the criterions. The equivalent model is verified through comparing with the test sloshing parameters. The results show that the differences of sloshing parameters are less than 5%, so that the equivalent model can provide a reference for the design of the rocket.
