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 ∝₀ fluctuates around 20°. When the maximum relative camber is greater than 10%, ∝₀ decreases gradually in the range of 32.5° to 22.5°; K _∝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, ∝₀ shows an upward trend in the range of 20° to 32.5°, and when the aspect ratio is greater than 2.0, the value shows a fluctuating trend around 20°. K _∝0 fluctuates and there is no obvious principle.
