平板形式的机翼的非定常俯冲(升降)在其形成的初始阶段会在小尺度前缘涡内引起显著的轴向流动。沿旋涡方向相反的轴向流动在对称面上相互作用，产生了大尺度的流向涡量模式，在振荡周期的部分时间内，这种涡型可以主宰尖端涡旋。
Unsteady plunging (heaving) of a wing in the form of a flat plate can give rise to pronounced axial flow in the small-scale leading-edge vortex, during its initial stage of formation. Opposing axial flows along the vortex interact at the plane of symmetry giving rise to large-scale patterns of streamwise-oriented vorticity, which can dominate the tip vortices over part of the oscillation cycle.
