摘要

地面效应是指当机翼贴近地面飞行时，由于受到地面的干扰作用而引起升力增加和阻力降低的现象。本文研究地面效应对颤振的影响规律。建立基于计算流体力学/计算结构力学耦合的颤振计算方法，采用标模AGARD 445.6机翼对颤振计算方法进行验证。在此基础上，以贴近地面的三维机翼为研究对象开展颤振分析，研究指出地面效应增强了非定常气动力的幅值，而且离地越近这种效果就越明显，从而导致颤振速度随着离地高度的降低而减小。然后重点讨论了攻角对地效翼颤振的影响，与不考虑地效的经典线性颤振理论不同，本文指出地效翼的颤振速度与攻角有关，在地效区域内，增加机翼的攻角会使发生颤振时的静变形变大，导致机翼抬起和离地高度增加，地效减弱，使得颤振速度随攻角的增大而提高。

Abstract

Ground effect refers to the phenomenon that the lift increases and the drag decreases due to the interference of the ground when the wing is flying close to the ground. The ground effect on flutter characteristics is investigated in this paper. The computational fluid dynamics / computational structural dynamics coupling method is constructed for flutter calculations. The AGARD wing 445.6 is adopted to validate the flutter calculation method. On this basis, the flutter analysis of a three-dimensional wing close to the ground is carried out. Results show that the ground effect can increase the amplitudes of unsteady aerodynamic forces and this effect becomes more significant as the wing gets closer to the ground, so that the flutter speed decreases with the decrease of ground clearance. Then, the influence of angle of attack on flutter characteristics of ground effect wings is discussed. Different from the classical linear flutter theory without the ground effect, this work points out that the flutter speed of ground effect wing is related to the angle of attack. In the region of ground effect, the increase of angle of attack will increase the static deformation for flutter, raising the wing and resulting in the increase of ground clearance, so that the ground effect is weakened and the flutter speed increases.
