Numerical Methods for Zoning Computation

P. Lalande & A. Delannoy
Zoning consists in establishing lightning strike zones to locate and classify surfaces on an aircraft which are exposed to a part of the lightning current components. The current standard used to certify aircraft is empirical and qualitative, and fails to predict certain features, such as lightning attachment on the middle of the wing. Furthermore, the standard will be difficult to apply to the next generation of aircraft having geometry, engines and fuselage material that will...
