Abstract
The hydrodynamic features of a falling mine into
the water column is investigated experimentally. The
experiment consisted of dropping three cylindrical model
mines of various lengths into a pool where the trajectories
were filmed from two angles. The controlled parameters were,
mine parameters (length to diameter ratio, center of mass
location), and initial conditions (initial velocity, and drop
angle). Results indicate that center of mass position has the
largest influence on the mines' trajectory and that accurate
trajectory modeling requires the inclusion of both momentum
and moment equations. A statistical-dynamic model has been
established to predict the trajectories of the falling mines.
