- Development of a lightning electromagnetic analysis method for CFRP for airplanes and the proposal of lightning protection design of airplanes
Baba Yoshjhiro
Carbon-fiber-reinforced-plastic (CFRP) panels used for airplanes are composed of many thin layers, the conductivity of each layer varies significantly dependent on the fiber direction. In this research work, a new method based on the finite-difference time-domain (FDTD) method, which includes the conductivity tensile matrix and the computation procedure of generated heat, has been developed. The developed method has been applied to analyses of a CFRP panel struck by lightning and other electric facilities. The representative results have been published in international and domestic journals as papers or short papers., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2018/04 -2022/03, Grant-in-Aid for Scientific Research (C), Doshisha University - A study of lightning protection of photovoltaic power generation systems on building tops
BABA YOSHIHIRO
For analyzing transient voltages generated in an electric power facility such as a photovoltaic power generation system struck by lightning with the finite-difference time-domain (FDTD) method, several models such as a corona-discharge model, an arbitrary-radius thin-wire model, and a high-performance absorbing boundary condition have been proposed, and their validities have been shown. Then, these models have been incorporated in the FDTD-simulation program developed by the author. Mechanisms on how overvoltages are generated have been studied with the FDTD program, and a countermeasure to reduce the lightning-caused overvoltage peaks has been proposed., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, 2015/04 -2018/03, Grant-in-Aid for Scientific Research (C), Doshisha University - 雷撃を受けた風力発電タワー等高構造物内部および近傍の過渡誘導電圧評価法の確立
