The invention relates to a method for designing an underwing gravity-unloaded plugin elastic protection rope of a flutter experiment model. Under the condition of foreknowing that the weight of a plugin object is m, the elastic coefficient k, elongation delta L and total length L of the elastic protection rope are determined. The method for designing the underwing gravity-unloaded plugin elastic protection rope the flutter experiment model is characterized by comprising the following steps that 1, the lowest inherent frequency fmin of the plugin object modal of the flutter experiment model is determined; 2, the elastic coefficient k of the elastic protection rope is calculated according to the following formula; 3, the elongation delta L of the elastic protection rope is calculated according to the following formula; 4, the total length L of the elastic protection rope is determined according to the following formula. According to the method for designing the underwing gravity-unloaded plugin elastic protecti
