The invention relates to a gas layer distribution state monitoring device for ship gas layer resistance reduction, which comprises a plurality of feature points arranged on a ship bottom plate, the feature points are arranged in the middle and on two sides of the ship bottom plate along the ship length direction, and the feature points arranged at the head of the ship bottom are distributed in a dissipation radian manner. The feature points arranged at the tail part of the ship bottom are distributed along with the molded line in a furling manner; the fixed base is arranged on a ship bottom plate, the bottom end of the automatic lifting rod is fixedly arranged on the fixed base, the top end of the automatic lifting rod is fixedly arranged on the fixed cover through a buckle, the viscometer is fixedly arranged on the fixed cover, and the viscometer is connected with the data processing module. The data processing module is connected with the automatic lifting rod and the GUI interface, and the probe is arranged at the bottom of the viscometer and located on a ship bottom plate. The method measures the thickness of the ship bottom gas layer, quantifies the state of the ship bottom gas layer, improves the gas layer quality monitoring accuracy, and avoids the increase of the additional resistance of the ship body.

本发明涉及一种用于船舶气层减阻的气层分布状态监测装置，包括设置在船底板的多个特征点，所述特征点沿船长方向设置在船底板的中间和两侧，设置在船底首部的所述特征点呈逸散弧度分布，设置在船底尾部的所述特征点呈随型线收拢分布；所述固定底座设置在船底板上，所述自动升降杆底端固定设置在固定底座上，所述自动升降杆顶端通过卡扣固定设置在固定盖上，所述固定盖上固定设置粘度计，所述粘度计与数据处理模块连接，所述数据处理模块分别与自动升降杆、GUI界面连接，所述探针设置在粘度计底部且位于船底板。本发明测量船底气层厚度，将船底气层状态量化，提高气层质量监测准确性，同时避免船体附加阻力的增加。
