Composite airframe structures ebook
Modern passenger jets have miles of wires and dozens of computers and other instruments that control everything from the engines to the passengers' headsets.
In this case, the composites contain an embedded layer of conductive fibers or screens designed to carry lightning currents.
Engineers thus take extreme precautions to ensure that lightning currents cannot cause sparks in any portion of an aircraft's fuel system.Although passengers and crew may see a flash and hear a loud noise if lightning strikes their plane, nothing serious should happen because of the careful lightning protection engineered into the aircraft and its win7 codec pack x64 sensitive components.In order to function, radar cannot be contained within a conductive enclosure.The aircraft skin around the fuel tanks must be thick enough to withstand a burn through.Since then, much has been learned about how lightning can affect airplanes.Aircraft Inspection Repair aging wiring to modern fiber optics rev 12; design build electrical systems in homebuilt aircraft drag reduction methods for small and homebuilt aircraft reassembly of Continental 0-200, Lycoming O-320, O-360, IO-360, lycoming 0-360 firewall forward materials and techniques for building composite structures.These strips can consist of solid metal bars or a series of closely spaced buttons of conductive material affixed to a plastic strip that is sony xperia p user guide bonded adhesively to the radome.In these instances, the lightning flash originates at the airplane and extends away in opposite directions.
The current will travel through the conductive exterior skin and structures of the aircraft and exit off some other extremity, such as the tail.
A basic level of protection is provided for the airframe, fuel system media player codec pack update checker popup and engines.The other main area of concern is the fuel system, where even a tiny spark could be disastrous.In fact, aircraft often trigger lightning when flying through a heavily charged region of a cloud.These transients are called lightning indirect effects.All the pipes and fuel lines that carry fuel to the engines, and the engines themselves, must be protected against lightning.
