Available in PDF, EPUB and Kindle. Book excerpt: The feasibility of using rocket-triggered lightning as a research and development tool for testing hardware is investigated. Previous experimental work in the area is examined and used as the foundation for the experiments in this thesis to establish the significant factors of a successful lightning-triggering station. Using a point charge model, computer simulations were performed to determine the most probable locations of the charge centers associated with the triggered discharge. Five electric field records obtained from field mills were used to perform this simulation. A full scale test technique configuration is proposed for subjecting representative Air Force subsystems and components to the lightning threat. A conclusion is drawn that such a system is feasible at Mt. Baldy, New Mexico with minor augmentations of the existing facilities of the Langmuir laboratory. (Author).

Book Synopsis Lightning: Principles, Instruments and Applications by : Hans Dieter Betz
Download or read book Lightning: Principles, Instruments and Applications written by Hans Dieter Betz and published by Springer Science & Business Media. This book was released on 2008-12-04 with total page 641 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 related human fatalities and damage to forests, buildings, power lines, aircraft, structures and electronic devices. In this volume, the most important contemporary questions on lightning are addressed and analyzed under many experimental and theoretical aspects. Lightning detection techniques using ground-based and space-borne methods are described, along with network engineering and statistical analysis. Contributions detail research on atmospheric electricity, cloud physics, lightning physics, modeling of electrical storms and middle atmospheric events. Special phenomena such as triggered lightning and sprite observations are examined. Lightning-induced nitrogen oxides and their effects on atmospheric chemistry and climate are discussed. Each topic is presented by international experts in the field. Topics include: * air chemistry * convective storms * infrasound from lightning * lightning and climate change * lightning and precipitation * lightning and radiation * lightning and supercells * lightning and thunderstorms * lightning detection * lightning from space * lighting protection * lightning return strokes * observations and interpretations * spatial distribution and frequency * triggered lightning * weather extremes

Available in PDF, EPUB and Kindle. Book excerpt: The dart-stepped leader in rocket-triggered lightning is examined in this dissertation with data collected from 2011 to 2013 at the International Center for Lightning Research and Testing at Camp Blanding in north-central Florida. A total of 53 triggered dart-stepped leaders were studied using primarily high-speed video cameras, a streak camera, and ten electric field derivative (dE/dt) measurements at close range (

This book was released on 2014-09-21 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since natural and artificially-initiated (or 'triggered') lightning are demonstrated hazards to the launch of space vehicles, the American space program has responded by establishing a set of Lightning Launch Commit Criteria (LLCC) and Definitions to mitigate the risk. The LLCC apply to all Federal Government ranges and have been adopted by the Federal Aviation Administration for application at state-operated and private spaceports. The LLCC and their associated definitions have been developed, reviewed, and approved over the years of the American space program starting from relatively simple rules in the mid-twentieth century (that were not adequate) to a complex suite for launch operations in the early 21st century. During this evolutionary process, a "Lightning Advisory Panel (LAP)" of top American scientists in the field of atmospheric electricity was established to guide it. This history document provides a context for and explanation of the evolution of the LLCC and the LAP. A companion document on the rationale is currently being prepared by the LAP to provide the physical, mathematical, and operational justification for the current LLCC. Lightning that takes place naturally in thunderstorms was recognized as a threat to spaceflight early in the space age, and the early launch rules prohibited flight through thunderstorms. What had not been recognized until Apollo XII was launched in 1969 was that an ascending rocket could "trigger" lightning if it flew into highly electrified clouds, even in the absence of natural lightning. Apollo XII was struck twice by triggered lightning, and as a result, additional rules were added to forbid flying within 5 NM of thunderstorms or through certain non-thunderstorm clouds that experience showed had the potential of being electrified. During the time between Apollo XII and the beginning of the Space Shuttle Program, several important research programs were carried out to learn more about lightning and cloud electricity in Florida, and additional instrumentation was installed at the KSC and Eastern Range (ER). The LLCC were modified for the Skylab program in 1973 and again for the Apollo-Soyuz Test Project in 1975. Expendable launch vehicles (ELV) had their own separate but similar rules. In 1979 the nascent Shuttle program adopted a set of LLCC that included constraints and waivers that were based on surface electric field mill measurements. The ELV rules did not adopt the field mill criteria. In 1987, triggered lightning caused the loss of Atlas/Centaur 67 (AC 67) and its Fleetsatcom payload. A major cause of this accident was the failure of the ELV rules to include a field mill criterion. The Shuttle rules would have prohibited the launch of AC 67. In the aftermath of several investigations and a Congressional Hearing, a lightning "Peer Review Committee," a predecessor of the LAP, was established to guide NASA and the Air Force in the drafting of LLCC and the conduct of associated research. Several major research projects were undertaken, including the first "Airborne Field Mill Program" (ABFM I, 1990-1992) in which direct measurements of electric fields in Florida clouds were made from a specially instrumented aircraft. ABFM I resulted in several improvements to the LLCC, and the lessons learned ultimately led to an even more successful ABFM II campaign a decade later. As new knowledge and additional operational experience has been gained, the LLCC have been updated to preserve or increase their safety and increase launch availability. All launches of ELV and manned vehicles now use the same rules, which simplifies their understanding and application and minimizes the cost of the weather infrastructure to support them. In the future, the processes and procedures that have evolved can be used to facilitate further improvements in both launch availability and safety as new research findings become available.
