<h2> Abstract </h2>
 This paper explores the impact of including fluid inertia in the analysis of the  attitude motions of variable mass systems.  This is done by assigning a non-zero  value for the ration of the fluid density to that of the solid portion of the  system.  The equations of attitude motions of the system are then solved in closed  form, and the time histories of the system's angular velocity components are  evaluated, with density ratio as parameter.
