The report covers the entire program to date on a laboratory investigation to obtain experimental information necessary for evaluation of current slosh-baffle designs and for verification and extension of existing theory on sloshing phenomena and control. A detailed understanding of propellant sloshing phenomena will permit rational design changes, if required, on Atlas, Titan and Thor, and will contribute toward the design of minimum-weight slosh control in future ballistic missiles and space exploration systems. The measurements for the principal objective of the original program plan 165-11 were completed. The data provided experimental verification of the currently-used theory for the forces on slosh-damping rings and resulted in an extension of the range of application of the theory. Other phases of the study resulted in a reassessment of areas now considered of primary importance and warranting further experimental investigation. Author
