Abstract
The Navy’s bomb maneuvering model
(STRIKE35) predicts the bomb location and trajectory in air
and water columns. The Bomb Strike Experiment for Mine
Countermeasure Operations, currently sponsored through the
Office of Naval Research mine and obstacle breaching
technology program, is part of a multi-year, comprehensive
effort aimed at enhancing the Navy’s fleet naval mine
clearance capability and success. The investigation discussed
in this thesis examines the experimental and theoretical
characteristics of a rigid body falling through the air, water,
and sediment column at high speed. Several experiments were
conducted to launch bomb-like rigid bodies with the density
ratio similar to operational munitions, namely the MK-84
general purpose bomb, into a hydrodynamic test tank.
Careful observations of the bomb-like rigid body’s position
and orientation were collected and analyzed to produce a
series of three-dimensional coordinate time-space data tables
and plots. The resulting data set reveals a strong correlation
between shape type and trajectory and dispersion patterns for
rigid bodies moving through the water column at high
velocity. This data will be used for development and
verification of the three-dimensional model bomb strike model
(STRIKE35) aimed at predicting the overall trajectory, maneuvering, burial depth and orientation of a falling high-velocity rigid body in the air-water-sediment column. The long-term goal of this project is to improve warhead lethality for use in quick, precise and accurate strikes on known enemy naval minefields in the littoral combat environment.
