The invention discloses a large-scale low-speed wind tunnel elastic full-model gust load retarding test system and method, and belongs to the technical field of wind tunnel test equipment. The device comprises a gust generator and a supporting device which are mounted in a wind tunnel, the supporting device comprises a model sliding guide rail, mounting seats and a tackle, the mounting seats are fixedly mounted at the two ends of the model sliding guide rail, the tackle is mounted on the model sliding guide rail, an airplane model is mounted on the tackle, and two parallel sliding rails are mounted on the mounting seats. The two sliding rails are both provided with sliding blocks, the two sliding blocks are connected through a sliding block connecting base, a lifting ring general assembly plate is installed on the sliding block connecting base, a plurality of first lifting rings are welded to the bottom face of the lifting ring general assembly plate, second lifting rings are welded to the mounting base, springs are hooked between the first lifting rings and the second lifting rings, and an optical shaft sleeve and an optical shaft are installed in the mounting base. One end of the polished shaft is fixedly installed on the sliding block connecting base through a bolt, and the other end of the polished shaft is fixedly provided with a limiting block. The device is compact in structure, easy to install and low in cost.
