Title:
空気力学的移動面を有する装置に用いるためのダンピングアッセンブリ
Document Type and Number:
Japanese Patent JP6843179
Kind Code:
B2
Abstract:
A damping assembly is described herein for use in a device having moving aerodynamic surfaces comprising: a first component 11 comprising a back iron 14 and at least one permanent magnet 12, said at least one permanent magnet 12 providing a first magnetic field, and an electrically conductive second component 13, said electrically conductive second component 13 and said first component 11 being positioned coaxially about a central axis 15 with said at least one permanent magnet 12 being positioned between said back iron 14 of said first component 11 and said electrically conductive second component 13; the assembly further comprising means for rotating one or both of said at least one permanent magnet 12 of said first component 11 and said electrically conductive second component 13 about said central axis 15 to cause relative rotational movement between the at least one permanent magnet 12 and said second component 13, to thereby induce a variable magnetic flux in said electrically conductive second component 13 and cause eddy currents to develop therein.
