The Influence Analysis of Attack Angle to Submarine's Motion State During Emergency Recovery of Flooded Compartment

摘要

The paper establishes emergency recovery maneuver model of six degree of freedom and blowing ballast compartment model of high pressure air.Based on standard maneuver equation, considering the influence of large angle of attack to hydrodynamics coefficient,correct the standard equation through supplementing hydrodynamics items. Applying large and small angle of attack system to simulate and calculate state parameters, and find the occasion of large of attack,the influence of initializtion velocity and depth to change of angle of attack. The results prove that large angle of attack system is significant to forecast the state parameters.
