Abstract: The mathematical development of an equivalent spring mass model is given, along with necessary assumptions, for two specific cases: that of the right circular cylinder, and the sphere. The approaches to a definition of the properties of tanks with approximately these shapes (the Saturn S-IV liquid hydrogen and liquid oxygen tanks) in terms of these simple shapes are then shown. The results of extensive testing of scale models of the tanks with liquids are then used to define the most suitable approach. Scaling parameters include damping as well as geometric scaling. A short discussion of the properties of damping baffles shows that important effects other than damping are sometimes introduced.
