Modeling and Simulation of Airborne Depth Charge for Driving out Submarine

The underwater blast power model of an airborne depth charge and the resisting shock wave model of a sub-marine hull are employed to compute the safe-radius to the depth charge and the largest effective-radius based on the analysis of driving out submarine principle. A method to ascertain the bomb-dropping aiming point position is proposed according to the bomb-dropping dispersion model and the target location model, namely, the aiming point of bomb-dropping is determined by weighing the probability of accomplishing driving out target mission and the probabil-ity of destroying a submarine. In addition, some examples with different target location conditions of sonobuoy and magnetic anomaly detector are simulated, and the results indicate that better operational effectiveness control can be achieved based on higher precisions of bomb-dropping and underwater target location.
