Available in PDF, EPUB and Kindle. Book excerpt: The aircraft industry, commercial utilities, and federal agencies, such as NASA, are investing in aircraft solutions for a more sustainable, cleaner, and quieter transportation solutions for people and cargo. One option that is actively considered is that of a hybrid-electric aircraft, and in this application the energy storage system (ESS) may consist of thousands or even tens of thousands of cells. These cells are then connected in series and in parallel to form modules, which then are assembled into battery packs to meet energy and power requirements, resulting in systems that are large-dimensional and that have complex interconnections. Because of differences in cell electrical and thermal characteristics and in cell aging, the energy/power density and the durability and safety of the battery packs will be reduced to a certain extent compared with individual cells. It is therefore very important to design a battery management system (BMS) that can enable cell level monitoring and that is capable of diagnosing faults that are considered to be critical. This dissertation presents some design aspects for a battery pack intended for aviation application and its BMS considering safety, health and safety monitoring, and diagnostics. Generalized equivalent circuit models (GECMs) are used to predict the overall battery pack performance and to investigate the different behavior of different battery pack architectures in the case of cell-to-cell parameter variations or in the case of faults. A comparative analysis between different battery pack architectures is conducted as well, to determine a better architecture that is more reliable in the case of a cell fault. A set of critical faults is selected for fault modeling to augment the battery cell model and pack model. The battery pack model with fault modeling is then used in a Software-In-the-Loop (SIL) framework under the NASA ULI hybrid turbo-electric aircraft case scenario with the purpose of understanding the performance of the battery system under different fault cases. A systematic model-based diagnostic methodology called structural analysis is used to determine the sensor placement strategies that are needed by the BMS to improve its ability to monitor and diagnose the battery system. The degree of analytical redundancy (AR) in the battery system that can be used for diagnostic strategies is determined using the tools of structural analysis. Structural models of different battery pack architectures are used to study how different measurements (current, voltage, and temperature) may improve the ability to monitor and diagnose a battery system. Possible sensor placement strategies that would enable the diagnosis of a set of critical faults for different battery pack topologies are analyzed as well. The optimal sensor sets that can meet both typical BMS requirements and also provide the necessary FDI requirements for the two fundamental battery architectures are determined using this novel methodology. A distributed fault diagnosis scheme is then proposed for a lithium-ion battery pack that can effectively detect and isolate individual cell faults, connection faults and sensor faults. The fault diagnostic algorithms are evaluated within the SIL simulation framework to show the functionalities of the proposed FDI scheme. This dissertation represents the first systematic approach to the design of battery systems for aviation applications that explicitly considers fault diagnosis and fault tolerance.

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 Unsettled Topics on the Use of IVHM in the Active Control Loop written by Rhonda Walthall and published by SAE International. This book was released on 2020-07-01 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth in global economies has led to a world that has become much more mobile in the last few decades. The number of enplanements has increased and is expected to continue to do so at an annual average rate of 1.8% through 2039 [1]. Prior to the COVID-19 pandemic, the number of aircraft in service was expected to increase annually to meet the travel demand. Next-generation, more-complex aircraft were scheduled to replace the older aircraft at a pace that still allowed sufficient capacity to meet the increasing demand. The events of 2020 have driven the industry to accelerate retirement of older aircraft while deferring the introduction of new aircraft. While the length of the industry recovery period cannot be predicted, most analysts believe that demand for travel will return once a vaccine is widely available. The impact to the design of next-generation aircraft will likely be shaped by technologies that are being accelerated for the post-COVID world as well as for new mobility platforms. Technologies, such as artificial intelligence and fault-tolerant and self-adapting control, will use integrated vehicle health management (IVHM) capabilities as part of the decision-making processes. This SAE EDGE™ Research Report seeks to explore the unsettled issues surrounding embedding IVHM information into the active control loops of modern aircraft systems and in future generations of aircraft designs. NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate key issues in emerging, but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE™ Research Reports is to stimulate discussion and work in the hope of promoting and speeding resolution of identified issues. SAE EDGE™ Research Reports are not intended to resolve the challenges they identify or close any topic to further scrutiny.

Available in PDF, EPUB and Kindle. Book excerpt: Power electronics technology is still an emerging technology, and it has found its way into many applications, from renewable energy generation (i.e., wind power and solar power) to electrical vehicles (EVs), biomedical devices, and small appliances, such as laptop chargers. In the near future, electrical energy will be provided and handled by power electronics and consumed through power electronics; this not only will intensify the role of power electronics technology in power conversion processes, but also implies that power systems are undergoing a paradigm shift, from centralized distribution to distributed generation. Today, more than 1000 GW of renewable energy generation sources (photovoltaic (PV) and wind) have been installed, all of which are handled by power electronics technology. The main aim of this book is to highlight and address recent breakthroughs in the range of emerging applications in power electronics and in harmonic and electromagnetic interference (EMI) issues at device and system levels as discussed in ‎robust and reliable power electronics technologies, including fault prognosis and diagnosis technique stability of grid-connected converters and ‎smart control of power electronics in devices, microgrids, and at system levels.

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.
