The system input in this case is turbulent air which produces random pitching motion of the vehicle.
在此情况下,系统的输入是紊流大气,它使飞行器产生随机俯仰运动。
For pure pitching motion, the results show that average drag coefficient decreases as airfoil thickness is reduced.
在低雷诺数条件下,对于纯俯仰运动,随着翼型厚度的减小,平均阻力系数也变小。
In this paper, by analyzing the forces on hydrofoil catamaran, the mathematical model of its heaving and pitching motion is proposed.
