| Popis: | The effect of the main-panel angle of a single-slotted cambered otter-board was investigated using engineering models in a wind tunnel. Three different angles (0°, 6°, and 12°) were evaluated at a wind speed of 28 m/s. Parameters measured included: drag coefficient Cx, lift coefficient Cy, pitch moment coefficient Cm, center of pressure coefficient Cp, and the lift–drag ratio Cy/Cx, over a range of angle of attack (0°–70°). These coefficients were used in analyzing the differences in the performance among the three otter-board models. Results showed that the maximum lift coefficient Cy of the otter-board model with a main-panel angle of 0° was highest (1.875 at α = 25°). However, when the angle of attack was smaller (0 |
