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.

Mine impact burial model (IMPACT35) verification and improvement using sediment bearing factor method Fan, Chenwu; Chu, Peter C. (2007);Recently, a 3-D model (IMPACT35) was developed to predict a falling cylindrical mine’s location and orientation in air–water–sediment columns. The model contains the following three components: 1) triple coordinate transform, ...
