Abstract

The effect of the deflector angular variation for single slotted cambered otter board on hydrodynamic performances was investigated by model wind tunnel test. Three otter board models with different deflector angle were designed for testing. The model test conducted in wind tunnel with the flow velocity at 28 m/s and the angle of attack measured from 0ø to 70ø. Model experiment was conducted to obtain drag coefficients Cx, lift coefficient Cy, calculated lift to drag ratio Cy/Cx and give the relations curve of these value and angle of attack . The result showed that the lift coefficient Cy of No.2 otter board model was higher, there was 1.875( =25ø); the Cy/Cx of No.1 otter board with smaller deflector angle would be higher, there was 6.555( =7.5ø), however, No.2 otter board model got the higher drag ratio (3.894) at the attack angle of highest lift coefficient. The results would offer reference for the structural optimization design of trawl otter board.
