Energy Harvesting/Regeneration for Electric Vehicles Land, Water & Air 2015-2025

2014-12-01

The electric vehicle industry - land, water and air - is rapidly rising to become a market of over $533 billion by 2025. Some run entirely on harvested energy as with solar lake boats. Others recycle energy as with regenerative braking of cars, buses and military vehicles harvesting kinetic energy. Others use different forms of harvesting either to charge the traction batteries, or to drive autonomous device. In some cases, harvesting is making completely new forms of electric vehicle possible such as "glider" Autonomous Underwater Vehicles (AUVs) that can stay at sea for years, gaining electricity from both wave power and sunshine. Multiple forms of energy harvesting on one vehicle are becoming more common from cars to superyachts.

Engineered Tribological Composites

2011-11-30

Roy Cox provides readers with a thorough presentation of the topic, beginning with the earliest work on brakes by Frood in the early 1900s and friction studies by daVinci in the 1400s. From there, details about the processes of wear and the components of tribological systems are presented. Methods of manufacturing friction materials are described, and the elements of friction material are detailed—binders, fibers, abrasives, and lubricants. A large portion of the book delves deeply into materials for binders, resins, fibers, abrasives, lubricants, and fillers, providing background on the various materials, their pros and cons, and numerous ways they can be applied to friction systems. Much of this discussion focuses on the compositional makeup and effects of ingredients as they relate to the wear and friction performance of the final product.

So You Want to Design Aircraft: Robots on the Floor

2017-07-27

It is ironic that as aircraft have gotten more sophisticated, much of their manufacture has remained manual. However, as orders for commercial aircraft have dramatically increased over the past years and are expected to remain on that trajectory, the competition has become not just about how fast new technologies can be put on the aircraft, but about how fast the aircraft can be manufactured and delivered. Enter ever increasing automation and robotics. Just as it has taken multiple years to reach the sophisticated content levels on current generation aircraft, so too has it been necessary to continually learn new ways and means to increase automation on the manufacturing floor. For both aircraft on the flight line and on the production line, safety is paramount.

Supply Chain Vulnerabilities Impacting Commercial Aviation

2019-09-04

Written by Kirsten Koepsel, a lawyer and engineer whose work has focused on aviation cybersecurity, Supply Chain Vulnerabilities Impacting Commercial Aviation addresses the big question facing aircraft manufacturers today: keep the work in house or outsource it? The ongoing battle between cost cutting and supply-chain control is ever more visible as aircraft OEMs have full order books and tight delivery schedules. Since the 1980s, commercial aviation, like many other industries, looked for ways of more economically sourcing parts and services. The new partnerships between OEMs and suppliers at multiple levels, did make the industry nimbler and more flexible. Yet, it also introduced a higher level of instability, risks and vulnerabilities to the aviation ecosystem.

The Aerospace Supply Chain and Cyber Security - Challenges Ahead

2018-07-20

The Aerospace Supply Chain and Cyber Security - Challenges Ahead looks at the current state of commercial aviation and cyber security, how information technology and its attractiveness to cyber attacks is affecting it, and the way supply chains have become a vital part of the industry's cyber-security strategy. More than ever before, commercial aviation relies on information and communications technology. Some examples of this include the use of e-tickets by passengers, electronic flight bags by pilots, wireless web access in flight, not to mention the thousands of sensors throughout the aircraft constantly gathering and sharing data with the crew on the ground. The same way technology opens the doors for speed, efficiency and convenience, it also offers the unintended opportunity for malicious cyber attacks, with threat agents becoming bolder and choosing any possible apertures to breach security.

Integrated Vehicle Health Management: Essential Reading

2013-09-25

Integrated Vehicle Health Management (IVHM) is a relatively new subject, with its roots back in the space sector of the early 1990s. Although many of the papers written around that time did not refer to it as IVHM, the fundamental principles of considering an integrated end-to-end system to monitor the overall health of the asset were clearly visible. As the subject of Integrated Vehicle Health Management (IVHM) and its associated technologies have grown up, businesses are making the transformation from selling a product to selling a service. This can be viewed as a positive disruption, as a relatively small technology breakthrough is being brought to market for a large business benefit. The sequence “sense—acquire—transfer—analyze—act “ feeds the information (processed data) on the asset’s health into the Operations or Management control center.

Aircraft Thermal Management: Systems Architectures

2016-03-02

Aircraft thermal management (ATM) is increasingly important to the design and operation of commercial and military aircraft due to rising heat loads from expanded electronic functionality, electric systems architectures, and the greater temperature sensitivity of composite materials compared to metallic structures. It also impacts engine fuel consumption associated with removing waste heat from an aircraft. More recently the advent of more electric architectures on aircraft, such as the Boeing 787, has led to increased interest in the development of more efficient ATM architectures by the commercial airplane manufacturers. The ten papers contained in this book describe aircraft thermal management system architectures designed to minimize airplane performance impacts which could be applied to commercial or military aircraft.

Additive Manufacturing of Aerospace Composite Structures: Fabrication and Reliability

2017-05-20

Additive Manufacturing of Aerospace Composite Structures: Fabrication and Reliability introduces the reader to the current state of technologies involved in processing and design of polymer-reinforced fiber composites using additive manufacturing's automated fiber placement methods, through ten seminal SAE International papers. Currently, the material layup strategy in terms of process selection and manufacturability is usually not prioritized in the design phase. Engineers do not have a good way to see how their design choices can affect the manufacturing process beyond their initial structural-level considerations. The result is typically a large amount of experimental testing necessary to qualify the materials and structures typified in the classical building-block approach. Such an environment makes mistakes difficult to solve and, should redesign be required, obtaining reliable information is hard to piece together.

Aircraft Thermal Management: Integrated Energy Systems Analysis

2016-03-02

The simultaneous operation of all systems generating, moving, or removing heat on an aircraft is simulated using integrated analysis which is called Integrated Energy System Analysis (IESA) for this book. Its purpose is to understand, optimize, and validate more efficient system architectures for removing or harvesting the increasing amounts of waste heat generated in commercial and military aircraft. In the commercial aircraft industry IESA is driven by the desire to minimize airplane operating costs associated with increased system weight, power consumption, drag, and lost revenue as cargo space is devoted to expanded cooling systems. In military aircraft thermal IESA is also considered to be a key enabler for the successful implementation of the next generation jet fighter weapons systems and countermeasures. This book contains a selection of papers relevant to aircraft thermal management IESA published by SAE International.

The Use of Electric Batteries for Civil Aircraft Applications

2018-12-10

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 Electrification of Civil Aircraft and the Evolution of Energy Storage

2017-08-28

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.
