Evaluation of Dynamic Anti-Sink Nonlinear Effects for Submarines

  • Based on the vertical plane nonlinear maneuverability motion equation and the damage flooding and ballast blowing equation, the submerged dynamic anti-sink equation for submarines is established. By calculating the dynamic anti-flooding motion of submarines after typical compartment damage, the nonlinear margin lines of dynamic saving moves are obtained under different initial velocity, water depth, and flooding regions. By analyzing these margin lines, 3 criterion parameters are proposed to measure the ship's sink-resistibility: the effects of high-pressure air blowing are largely determined by water depth, and the effects of hydrodynamics are based on the initial speed and speed coefficients.
