Flutter test flight excitation device and method

The invention discloses a flutter test flight excitation device, and the device comprises a front wing which is in the shape of a circular truncated cone, the front wing is hollow, and the two ends of the front wing are open; a notch is formed in the side surface of the front wing in the generatrix direction, and a first supporting rod is connected between the two side walls of the notch. The first end of the rotating shaft extends into the front wing from the small-diameter end of the front wing, the first end of the rotating shaft is connected with a second supporting rod, and the two ends of the second supporting rod are connected with the inner wall of the front wing respectively; the output end of the driving device is connected with the second end of the rotating shaft, and the driving device is used for driving the rotating shaft to rotate; and the signal acquisition device is used for acquiring the excitation signal. The aerodynamic force is adopted as a source of exciting force, full excitation can b
