Optimization of Slosh Baffle Geometry

This paper describes a method for determining the optimum baffle configuration for suppressing excessive propellant sloshing in the tanks of a large launch vehicle. The optimum geometry for a baffle system is considered to be the one with the least mass which is capable of providing the necessary damping. The analysis considers a cylindrical tank and a baffle system made up of several flat ring baffles mounted horizontally. The basic assumptions are discussed and derivations given of the equations necessary to predict the optimum baffle configuration consistent with adequate strength. Numerical results are presented graphically, and some general conclusions are drawn.
