| Summary |
Numerical ａｎａｌｙｓｉｓ of membrane blades of hybrid power generating system (Lotus-1) subjected to wind pressure is executed by using Bendable Element Method (BEEM) [1]. In winter season, this system works as windmill and in summer season, works as solar power generating system by changing its configuration. The surface of membrane blade can reflect solar radiation and to focus them to photovoltaic (PV) panels. In order to keep smooth surface, pre-tensile membrane stress is introduced by cables. The main aim of this numerical analysis is to investigate the safety of membrane material and focusing ability of the surface of blade subjected to wind force. As the results, it appeared that the maximum principal stress is small enough compare to the maximum strength of membrane. The focal point on the PV panel draft 0.25m and 0.65m at the case of 17m/s (15kgf/m2) and 42m/s (90kgf/m2), respectively.ls, the NOx removal ability is estimated by CFD analysis.
