Avionics lightning protection design GUI
In order to build aircraft that are lighter and thus, use less fuel, aircraft manufacturers have begun using carbon composite material to fabricate the airframes instead of aluminum. An undesired effect of this change is the increase in severity of the indirect effects of lightning strikes to the airframe on the electrical equipment used on the aircraft (avionics). The more severe lightning tra...
متن کاملSimulation of Lightning Surge Propagation in Transmission Lines Using the FDTD Method
power transmission lines. Numerical computation of solving the Telegraphist’s equations is determined and investigated its effectiveness. A source of lightning surge wave on power transmission lines is modeled by using Heidler’s surge model. The proposed method was tested against medium-voltage power transmission lines in comparison with the solution obtained by using Bewley lattice diagram. As...
متن کاملUsing Subgridding FDTD Method to Incorporate Air Gap Breakdown in the Analysis of Lightning Induced Voltage
A subgridding formulation of Agrawal coupling equations of transmission line with branch and distributed electromagnetic excitation is proposed. This algorithm enables us to solve the transmission line system using different temporal and spatial step on different branches. The method is used to calculate the lightning induced over-voltage on the transmission line installed with air gap componen...
متن کاملbuckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Lightning Protection
Lightning causes deaths, injuries, damages, and significant costs and losses around the world. The global lightning flash rate is in the range of 40 to 100 lightning flashes per second, of which about 30 % are cloud-to-ground flashes. The development of theoretical and experimental researches is crucial for a better understanding of the physical phenomenon and for the characterization of lightn...
