The invention relates to the technical field of eVTOL, in particular to an eVTOL water forced landing airworthiness test method and a test device. The invention discloses an eVTOL airworthiness test method. The method comprises the following steps: making an eVTOL scaling model; preparing a test device; an eVTOL scale model water entry impact test is carried out; performing finite element simulation on the water impact test of the eVTOL scaling model; and performing finite element simulation on the water impact test of the eVTOL real machine. The eVTOL scale model is manufactured through the 3D printing technology, the problem that the interior of the model is difficult to machine through traditional wood or foam materials is solved, and the purpose of rapidly manufacturing eVTOL scale models of different sizes and shapes is achieved; by comparing the test result of the eVTOL scaling model with the finite element simulation result, the accuracy and effectiveness of the finite element analysis method in the eVTOL forced landing research are improved, and the new eVTOL initial airworthiness test technology is expanded.
