Abstract
This research proposes a wing-shaped poop which cleverly combines the poop and the wing sail. The wing-shaped poop with the length of 60 m and the height of 16.5 m is designed. The influence of the camber ratios (0.15–0.30) and the thickness ratios (0.10–0.20) on the performance of wing-shaped poop is analyzed. The lift coefficient of the poop increases first and then decreases with the increase of camber ratio and decreases with the increase of thickness ratio. The maximum lift coefficient (2.27) is obtained when the camber ratio is 0.25 and the thickness ratio is 0.1. Considering the influence of the rudder, when the apparent wind angle is 130°, the effective thrust of the poop reaches the maximum of 82 kN. Besides, when the wind comes from the bow, the shape of the poop is changed to reduce wind resistance caused by the wing-shaped poop.
