Swing blade type gust generator and design method thereof

The invention discloses a swing blade type gust generator and a design method thereof, and belongs to the technical field of wind tunnel test equipment. In order to solve the problem of gust simulation errors caused by large coupling vibration with a wind tunnel body when the existing generator structure realizes gust simulation, the number of parts of the generator in the wind tunnel is reduced, and the quality of a gust flow field is improved. The device comprises a supporting frame, a swing driving mechanism, a blade rotating shaft fixing seat and blades, the supporting frame is a square frame formed by welding and splicing profile steel, the swing driving mechanism is installed on the supporting frame, the swing driving mechanism and the blade rotating shaft fixing seat are installed on the supporting frame, and the number of blade assemblies is two. The two sets of blades are installed in the blade rotating shaft fixing installation base through rotating shafts, the swing driving mechanism is used for dr
