摘要： As an important accessory of Antarctic krill fishing gear, otter board has the effect of providing net horizontal expansion. To study the effects of aspect ratio and maximum relative camber on the hydrodynamic performance of Antarctic krill otter board, provide theoretical basis for the design and optimization of the otter board, the hydrodynamic performance parameters were analysed by flume model experiments.The results show: with the increase of aspect ratio, C-Lmax and K-max show an upward trend; when the maximum relative camber is less than or equal to 10%, the value of proportional to(0) fluctuates around 20 degrees. When the maximum relative camber is greater than 10%, proportional to(0) decreases gradually in the range of 32.5 degrees to 22.5 degrees; K proportional to(0) increases firstly and then decreases. With the increase of maximum relative camber, C-lmax shows an upward trend; K(max)shows a downward trend; when the aspect ratio is less than or equal to 2.0, proportional to(0) shows an upward trend in the range of 20 degrees to 32.5 degrees, and when the aspect ratio is greater than 2.0, the value shows a fluctuating trend around 20 degrees. K proportional to(0) fluctuates and there is no obvious principle.
