This book was released on 1986 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of Phase I were to investigate the use of simple corona current instrumentation on aircraft to measure thunderstorm electric fields and to conduct a feasibility study of a single station aircraft lightning interferometer to detect the occurrence and position of lightning. Both of these techniques have the common purpose of providing warning to aircraft crews when they are approaching potentially hazardous clouds and thunderstorms. The electric field measurement has the advantage of detecting electrified clouds which may not be producing lightning flashes but are nevertheless dangerous because an aircraft can trigger lightning; however this is a relatively short range system (on the order of 10 to 20 miles). The interferometer, which responds to RF pulses from lightning, has the advantage of long range detection (more than 100 miles) and can map the the position of lightning flashes in a manner similar to the way radar maps areas of rain. Thus the systems complement each other.

Download or read book Lightning Engineering Physics Computer based Test bed Protection of Ground and Airborne Systems written by Paul Hoole and published by Springer Nature. This book was released on 2022-02-11 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a contemporary and comprehensive overview of the physics of lightning and protection systems, based on nearly 40 years of research, teaching, and consultancy work in this area. The book begins with an overview of the climatology of lightning and electric storms, as well as giving insight into lightning discharge from the preliminary discharges or processes such as corona, stepped leader, and subsequent return strokes, including the important submicrosecond threats and continuous current. The subsequent chapters present measures of lightning threat analysis to aircraft and electric power systems, protection measures to be used in high-voltage to low-voltage computer and communication systems, as well as to commercial and domestic buildings. The book discusses challenges posed by the submicrosecond lighting current changes and climate change to present and future high-voltage apparatus and structures (including carbon composite aircraft and new buildings) exposed to lightning strikes. Including worked examples, illustrations, and detailed analysis, Lightening Engineering will be of interest to electrical engineers, as well as researchers and graduate students.
Download or read book Airborne Measurements of Transient Electric Fields and Induced Transients in Aircraft Due to Close Lightning written by Jerome T. Dijak and published by . This book was released on 1977 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The electromagnetic environment near lightning and thunderstorms and the induced effects of this environment on aircraft wiring was measured as part of Project Thunderstorm (TRIP-76). Instrumentation consisted of an externally mounted transient electric field sensor, induced transient sensors within the aircraft, a discrete spectrum analyzer, and a computer-based waveform digitizing system for high-resolution, high-frequency measurements. The electric field environment near thunderstorms was found to be very active with transients even when no lightning was evident. This environment was also responsible for inducing transients on wiring within the aircraft on an almost continuous basis in the vicinity of storms. The spectral content of pulses observed externally and internally on the aircraft varied widely with time. Comparison between the induced transients due to an accidental direct lightning strike to the aircraft and those due to a nearby strike showed the magnitudes of the effects due to the nearby strike to be nearly half those of the direct strike. The induced transients observed in the Learjet were similar in duration, magnitude, and frequency content to those observed during ground simulated lightning tests on other aircraft.

This book was released on 2008 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Cloud-to-ground lightning strikes present a clear and immediate danger for ground personnel involved in outdoor ramp operations, such as aircraft fueling, baggage handling, food service, tug operations, and guiding and directing aircraft to their assigned gates. When this danger presents, airport ramp operations are suspended until the threat has passed. Airport staff engaged in outdoor activities are also subject to the impact of lightning strikes. Decisions about ground personnel and ramp operations are made by the airports and airlines, not by the Federal Aviation Administration (FAA). Individual airlines, companies providing airport workers, and airport management often have very different procedures and standards for identifying and responding to potential lightning hazards."--Page 1

Available in PDF, EPUB and Kindle. Book excerpt: This book is an attempt to present under one cover the current state of knowledge concerning the potential lightning effects on aircraft and that means that are available to designers and operators to protect against these effects. The impetus for writing this book springs from two sources- the increased use of nonmetallic materials in the structure of aircraft and the constant trend toward using electronic equipment to handle flight-critical control and navigation function.
