Although in aircraft design it is possible to use baffles to suppress dynamic effects of contained liquids, approach is not as feasible in design of booster vehicles and spacecraft; analysis and evaluation presented are similar to those employed by J.W. Miles; it consists of formulating generalized functions that describe compatible deformations of shell and liquid; kinetic and potential energy expressions are formed and equations governing modal motion derived by application of Lagrange's equations; calculations are made for study of modal behavior of tank; results are presented in form of modal frequency vs liquid level, with cylinder-hemisphere stiffness ratio as parameter.
