    Lightning protection equipment for overhead contact line system is installed by a lightning protection map based on IKL (isokeraunic level). The IKL was created by data observed over 50 years ago, so we are planning to revise the lightning protection map. A new lightning protection map is created by data observed from to rents [25]. Thus the triggered lightning are much more like the ground-to-cloud lightning. Trying to avoid this shortcoming in the newest ex-periments of the initiated lightning the so-called alti-tude triggered method is used [40]. The rocket pulls up a part of the metal wire a few hundreds of meters long (not connected to the ground).

    The most frequent question encountered in the long history of the study of ball lightning is not how the ball is formed or what its properties are, controversial as these problems may be. It is, rather, whether ball lightning really : Stanley Singer. the analysis of the mechanisms of radome protection with lightning diverters of various types and sizes. A high voltage arrangement and associated diagnostics have been implemented to perform a quantitative study of the inception and propagation mechanisms of the corona and leader discharges that precede the final breakdown.

Get this from a library. Experimental and analytic studies of triggered lightning environment of the FB. [Terence Rudolph; United States. National Aeronautics and Space Administration. Scientific and Technical Information Division.;]. AIREX: Experimental and analytic studies of the triggered lightning environment of the FB The triggered lightning environment of the FB aircraft is investigated.

Scale modeling of the FB with a metallized model was done to measure electric field enhancement factors on the aircraft and on canonically shaped conducting objects. The goal of the FB Thunderstorm Research Program is to characterize the lightning environment for aircraft in flight.

This report describes the application of numerical electromagnetic models. and dI/dt sensors with ranges set for a large lightning flash at a distance of 35 km.

The environment of the aircraft was surveyed with a digital onboard weather radar and an onboard lightning detector. Aircraft instrumentation for direct lightning strike studies Four aircraft have been instrumented specifically for direct lightning strike studies.

Lightning represents a natural phenomenon of substantial interest. Due to its complex nature, research continues in many countries and reveals amazing results. Lightning is actively observed because of its relevance to Earth climate and air composition in addition to the classical aspects of.

The CV data was investigated in a mostly qualitative sense, while the FB data was subjected to both statistical and quantitative analysis using linear triggered lightning finite difference Author: Daniele Biron.

The results show that the five triggered lightning flashes include 1 to 10 return strokes, and the average return stroke current is kA with a maximum of kA and a minimum of kA, similar to the subsequent return strokes in natural by: Much of our knowledge of aircraft-triggered lightning is based on the data gathered by four major instrumented aircraft campaigns [5, 6]: the Rough Rider project, involving an FF (Air Force.
