The invention provides an amphibious aircraft elastomer test model, and belongs to the technical field of amphibious aircraft model water load tests.The amphibious aircraft elastomer test model comprises a segmented fuselage part and wing parts, the segmented fuselage part is composed of seven segments, the distance between every two adjacent segments is 20 mm, and the wing parts are connected with the segmented fuselage part. Every two adjacent sections are bonded through soft rubber so that the flexibility and water tightness of the adjacent sections can be kept. The front end face and the rear end face of each subsection are provided with transverse partition frames used for fixing the subsection faces. According to the invention, the flutter phenomenon in waves can be simulated, and structural characteristic distribution such as fuselage mass/rigidity and the like can be well restored.
本发明提供一种水陆两栖飞机弹性体试验模型,属于水陆两栖飞机模型水载荷试验技术领域,该水陆两栖飞机弹性体试验模型包括:分段机身部件、机翼部件,分段机身部件由7个分段构成,相邻两个分段之间的距离为20mm,相邻两个分段之间用软橡胶粘接,以保持相邻分段的柔韧性以及水密性;每个分段的前后端面设置有用于固定分段面的横向隔框;通过本发明可以模拟波浪中颤振现象,较好还原机身质量/刚度等结构特性分布。
