The Interaction of Lightning with Aircraft and the Challenges of Lightning Testing
Aircraft are struck by lightning in flight with some regularity and are required to have demonstrated protection against this threat; much of this demonstration is provided by simulating in test the effects of lightning on aircraft structures, components and systems. Clearly these tests need to be carried out in a representative manner and guidance on how to do this is provided in the Aerospace...
متن کاملIndirect Effects of Lightning on Aircraft and Rotorcraft
This article discusses issues related to indirect lightning on aircraft/rotorcraft. The standard waveforms used for qualifying the vulnerability of a system are introduced, with their frequency spectrum. The identification of the elementary EM coupling phenomenon allows the understanding of the key drivers of the current distribution and field scattering on a complex structure. The system level...
متن کاملA Fiber-optic Aircraft Lightning Current Measurement Sensor
A fiber-optic current sensor based on the Faraday Effect is developed for aircraft installations. It can measure total lightning current amplitudes and waveforms, including continuing current. Additional benefits include being small, lightweight, non-conducting, safe from electromagnetic interference, and free of hysteresis and saturation. The Faraday Effect causes light polarization to rotate ...
متن کاملStudy of Effects of Lightning Strikes to an Aircraft
In-flight statistics show that most strikes occurred 3-5 km above sea level, where the temperature is ~ 0C (Uman & Rakov, 2003; Larsson, 2002). There are two different types of lightning strikes to aircraft. The first type is that the aircraft initiates the lightning discharge when it is found in the intense electric field region of a thundercloud, and the second is the interception by the air...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
