Abstract

The present invention relates to a wing swing amplitude testing device for an airplane during a Dutch roll. The wing swing amplitude testing device effectively solves the problem that an existing wing swing testing device cannot linearly and continuously simulate airplane maneuvering actions. According to the technical solution, the device can linearly simulate an airplane to execute Dutch roll actions of different strengths, and on the premise that safety is guaranteed, the limited action of the airplane is determined according to the swing amplitude of the wings, the device can further conduct corresponding adjustments according to different airplane types, and the wing swing amplitudes of different airplane models can be tested when the different airplane models execute a Dutch roll.
