转子翼驱动功率与升/阻力特性研究
Driving power and lift/drag characteristics of rotor swings
摘要
Abstract
This paper proposed a method for calculating the drive power of a servo system based on the dynamic fluid torque and average angular velocity on the rotor wing to investigate the driving power of the new Magnus rotor-type anti-rolling device(rotor wing).First,we conducted three-dimensional transient simulations on a rotor swing using the soft ANSYS-Fluent,obtaining the hydrodynamic characteristics during the rolling period.Then,according to the dynamic fluid force and the angular velocity of the rotor,we obtained the total torque on the rotor wing,including inertial torque,friction torque,and viscous resistance torque.The results showed that the average lift-to-drag ratio was greater than 4 at a sailing speed of 7 knots for a rotor wing with a length of 3 m and a diameter of 0.4 m.The rotor wing can also generate sufficient lift at low speeds.Furthermore,the lift per unit projected area of the rotor wing was greater than traditional fins,whereas the opposite result was obtained for drag.Finally,the driving power of a rotor wing is less than that of a traditional stabilizing fin.关键词
