Variable-cross-section rotating cylinder for improving wind energy utilization and ship applying variable-cross-section rotating cylinder

The utility model relates to a variable cross-section rotating cylinder for improving wind energy utilization and a ship applying the same, which comprises a rotor body, an upper end plate and a lower end plate are respectively arranged at two ends of the rotor body, the rotor body is axially and vertically mounted for use, and the cross section of the rotor body is circular; the radius of the cross section of the rotor body is increased along with the increase of the axial height. The rotor body is in a circular truncated cone shape, the small end of the rotor body is connected with the lower end plate, and the large end of the rotor body is connected with the upper end plate. Aerodynamic characteristics and boosting effects are remarkably improved, output power of a ship propulsion main engine is remarkably reduced, and wide engineering application prospects are achieved. 本实用新型涉及一种改善风能利用的变截面转动柱体及其应用的船舶，包括转子本体，所述转子本体的两端分别设置上端板、下端板，所述转子本体轴向竖直安装使用，其横截面为圆形；转子本体的横截面半径随轴向高度升高而增大。所述转子本体为圆台形，转子本体的小端与下端板连接，转子本体的大端与上
