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.

This book was released on 2018-12-10 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Use of Electric Batteries for Civil Aircraft Applications is a comprehensive and focused collection of SAE International technical papers, covering both the past and the present of the efforts to develop batteries that can be specifically installed in commercial aircraft. Recently, major commercial aircraft manufacturers started investigating the possibility of using Li-Ion batteries at roughly the same time that the military launched their first applications. As industry events unfolded, the FAA and committees from RTCA and SAE continued efforts to create meaningful standards for the design, testing, and certification of Li-Ion battery systems for commercial aviation. The first document issued was RTCA DO-311 on Mar. 13, 2008. As the industry continues to develop concepts and designs for the safe utilization of the new Li-Ion battery systems, many are already working on designs for all-electric aircraft, and small two-seat training aircraft are currently flying. The challenges for an all-electric, transport category aircraft will be significant, and the battery design ranks as one of the greatest. The more energy that is packaged into a small area to provide for the propulsion requirements, the more stringent are the design parameters and mitigation methodologies needed to make the system safe. The success or failure of this endeavor lies squarely on the shoulders of the engineers and scientists developing these new systems, and places additional pressure on the regulatory agencies to acquire the relevant knowledge for the creation of minimum operational performance standards for them. Edited by Michael Waller, an industry veteran, The Use of Electric Batteries for Civil Aircraft Applications, is a must-read for those interested in the new power generation making its way into commercial aircraft.

This book was released on 2016-08-09 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary human activities that release carbon dioxide (CO2) into the atmosphere are the combustion of fossil fuels (coal, natural gas, and oil) to generate electricity, the provision of energy for transportation, and as a consequence of some industrial processes. Although aviation CO2 emissions only make up approximately 2.0 to 2.5 percent of total global annual CO2 emissions, research to reduce CO2 emissions is urgent because (1) such reductions may be legislated even as commercial air travel grows, (2) because it takes new technology a long time to propagate into and through the aviation fleet, and (3) because of the ongoing impact of global CO2 emissions. Commercial Aircraft Propulsion and Energy Systems Research develops a national research agenda for reducing CO2 emissions from commercial aviation. This report focuses on propulsion and energy technologies for reducing carbon emissions from large, commercial aircraftâ€" single-aisle and twin-aisle aircraft that carry 100 or more passengersâ€"because such aircraft account for more than 90 percent of global emissions from commercial aircraft. Moreover, while smaller aircraft also emit CO2, they make only a minor contribution to global emissions, and many technologies that reduce CO2 emissions for large aircraft also apply to smaller aircraft. As commercial aviation continues to grow in terms of revenue-passenger miles and cargo ton miles, CO2 emissions are expected to increase. To reduce the contribution of aviation to climate change, it is essential to improve the effectiveness of ongoing efforts to reduce emissions and initiate research into new approaches.

Download or read book The Electrification of Civil Aircraft and the Evolution of Energy Storage written by Michael Waller and published by SAE International. This book was released on 2017-08-28 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Larger airframes drove the development of electrical systems, capable of quickly and reliably starting the new higher power engines. These soon gave rise to the need for engine-mounted electrical generators as the primary source of in-flight power for the electrical loads and onboard recharging of the aircraft battery system. Of all the backup power sources, batteries represent the most common means of storing energy for auxiliary or emergency power requirements. It is not unusual for a typical commercial airliner, such as a B-737 or A-320, to have dozens of batteries on board. Over time, multiple battery chemistries were put to the test and the industry is still working on the optimal option. The lithium-ion technology has been gaining acceptance, with some important aspects to be considered: the application type, basic safety requirements and the presence or absence of humans on the vehicle. The Electrification of Civil Aircraft and the Evolution of Energy Storage, edited by Michael Waller, presents 10 seminal SAE technical papers which address multiple aspects of specific design, cell configuration and mitigation strategies in the case of battery failure. Additionally, with all the changes resulting from monitoring, control, and performance/safety test criteria, battery manufacturers have found themselves becoming systems integrators, having to quickly acquire knowledge of electronics and system modeling. As new technologies become available, industry will attempt to take advantage of all potential benefits, in a process that can have a profound impact on the product offerings that emerge and in the way business is conducted. The Electrification of Civil Aircraft and the Evolution of Energy Storage presents a solid perspective on how civil aviation has matured in its quest to develop lighter, more efficient and less polluting aircraft, and also more electric.

Download or read book Development of Large Li Ion Batteries for Aircraft and Spacecraft Applications written by and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This program was initially focussed on the development of very large rechargeable Li/SO2 cells for use as a survival pow source in missile silos. With the diminishment in the strategic value of these missile systems came a redirection of the program towards smaller cell silos. Concurrent was a chemical direction which changed the emphasis of the program from the rechargeable Li/SO2 chemistry to that of the family of cell chemistries which are collectively referred to as lithium ion. These cells are based on a metal oxide cathode, a carbon-lithium intercalation anode and an electrolyte solution consisting of a mixture of organic solvents and a soluble Li salt. These systems moved to the forefront of advanced battery technology in the early 1990s because they clearly offered significant improvements in cycle life, cell safely and energy density/specific energy. More recently, it became clear that spacecraft batteries based on large (20 to 100-Ah) Li ion cells would offer a significant reduction in spacecraft power system mass and the USAF Phillips laboratory joined Wright laboratory and Canada's DND in the sponsorship of this program.
