摘　　要：为揭示低压吹除过程中潜艇及舱内压载水的运动规律、提供潜艇操纵控制依据,建立单壳体潜艇螺杆压气机低压吹除系统动态过程模型,根据实艇情况验证了模型计算得到的吹除时间。分析了压载水舱形状结构参数和潜艇总体及系统设计参数对低压吹除过程的影响。研究结果表明,压载水舱截面形状对潜艇低压吹除过程有一定影响,随压气机流量增大,吹除时间缩短速率减小,随潜艇外形尺寸增大,吹除时间增加的速率增大。A dynamic model taking the effect of air pressure in water tank on deballsting process into considered is developed. Deballasting duration calculated by the model agree well against experimental data. Effect of sytem parameters of submarine and water tank on the deballsting process is studied. The results show that water tank section shape has a few effect on deballsting pressure and velocity but few on submarine draugt. It is also found that the velocity of deballasting duration growth decreases as air mass flow rate decreases and submarine outline increases.
