DESIGN METHOD OF FLEXIBLE PROPELLER BY FLUID-STRUCTURE INTERACTIVE ANALYSIS

摘要

A propeller made of a flexible material known as the flexible propeller lacks of structure rigidity. Accordingly, a blade shaped structure of the flexible propeller can be easily deformed when being applied by a load and has the possibility of not being able to operate under the optimal conditions in a heavy-load condition. Theoretically, the hydrodynamic performance applied on the propeller should be estimated to solve such problems, and a structure analysis method for estimating the deformation of the wing based on the hydrodynamic load is required. Accordingly, the present invention provides the method for designing a flexible propeller by considering the deformation through linking a hydrodynamic interpretation program and structure interpretation codes.
