Download or read book Advanced Maintenance Free Aircraft Battery System AMFABS written by and published by . This book was released on 1998 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vented nickel cadmium (NiCd) batteries are used in most main aircraft battery applications. To keep the batteries fully charged and at their rated capacity, they require a topping charge or overcharge. This overcharge process results in conversion of water into gaseous oxygen and hydrogen. Over several charge and discharge cycles, these gasses escape from the cell vent caps, resulting in water usage and forcing a maintenance action to keep the battery in a healthy state. This maintenance, which requires special facilities and training, drives up the life cycle costs of vented battery systems. Over the past few years, there have been several initiatives to reduce the operating costs of aircraft batteries. In particular, the United States Air Force (USAF) is involved in the development of maintenance free battery systems. There are two general approaches to reduce the maintenance cost of batteries. One approach is to develop a disposable battery system, such that after some interval the battery is simply replaced. The other approach is to develop a battery system that will function properly without maintenance for an extended period. The subject of this report is a system that does not require any scheduled maintenance for the design life of the aircraft. This approach is currently used in spacecraft applications where battery maintenance is not practical.
Download or read book StarBriefs 2001 written by and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 805 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compilation probably looks like one of the craziest things a human being could spend his or her time on. Yet nobody would wonder at someone taking a short walk every day - after twenty five years that person would have covered a surprisingly long distance. This is exactly the story behind this list, which appeared first as a few pages within the directory StarGuides (or whatever name it had at that time) and as a distinct sister publication since 1990. The idea behind this dictionary is to offer astronomers and related space scientists practical assistance in decoding the numerous abbreviations, acronyms, contractions and symbols which they might encounter in all aspects of the vast range of their professional activities, including traveling. Perhaps it is a bit paradoxical, but if scientists quickly grasp the meaning of an acronym solely in their own specific discipline, they will probably encounter more difficulties when dealing with adjacent fields. It is for this purpose that this dictionary might be most often used. Scientists might also refer to this compilation in order to avoid identifying a project by an acronym which already has too many meanings or confused definitions.

Download or read book Advanced Battery System for Aircraft written by and published by . This book was released on 1995 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: The deliverable systems are designed to have maintenance free operation for 3 years or 1000 flight hours. The goal of achieving a sealed NiCad battery and a microprocessor controlled charger was also met. Although the contract scheduling required ELDEC and EPI to perform much of the battery and charger development in parallel, at program end an integrated and reliable system was delivered. Trade-offs were performed during the development of the hardware. In the case of the Advanced Battery System a listing of lessons learned or recommendations is presented.
Download or read book Abbreviations Acronyms and Alphabets of Aviation written by Anne Millbrooke and published by Xlibris Corporation. This book was released on 2008-11-26 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intended for anyone who reads aviation literature, this guide contains over 12,000 shorthand expression used in aviation, past and present. The coverage is inclusive of general and technical terms, civil and military, also aeronautical, bureaucratic, commercial, geographical, mechanical, medical, meteorological, operational, and organizational terms — as related to aviation. All the abbreviations, acronyms, and alphabets — contractions or shorthand expressions, including mnemonics and even codes — were found in current and past aviation literature, including articles, books, charts, handbooks, manuals, maps, placards, weather reports, and notices to airmen. Often terms appeared without definition, in the apparent assumption that the meaning was general knowledge, and it may have been to the intended audience at that time. Many of the expressions stand for more than one thing, like MEL being "minimum equipment list" or "multi-engine landplane." TC could be "top of cylinder," "training center," "Trans Caribbean Airways," "Transport Canada," "transportation corps," "troop carrier," "tropical cyclone," "true course," "turbocharged," "turn coordinator," or "type certificate" — depending upon the context. Annotations in this volume are to help identify context. Some annotations place terms in time; for example, when did AFCC refer to the Air Force Combat Command, when to the Air Force Communications Command, and when to Air Force Cyberspace Command?

Download or read book Informed Architecture written by Marco Hemmerling and published by Springer. This book was released on 2017-07-19 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book connects the different topics and professions involved in information technology approaches to architectural design, ranging from computer-aided design, building information modeling and programming to simulation, digital representation, augmented and virtual reality, digital fabrication and physical computation. The contributions include experts’ academic and practical experiences and findings in research and advanced applications, covering the fields of architecture, engineering, design and mathematics. What are the conditions, constraints and opportunities of this digital revolution for architecture? How do processes change and influence the result? What does it mean for the collaboration and roles of the partners involved. And last but not least: how does academia reflect and shape this development and what does the future hold? Following the sequence of architectural production - from design to fabrication and construction up to the operation of buildings - the book discusses the impact of computational methods and technologies and its consequences for the education of future architects and designers. It offers detailed insights into the processes involved and considers them in the context of our technical, historical, social and cultural environment. Intended mainly for academic researchers, the book is also of interest to master’s level students.
