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.

Reader's Favorite Gold Medal Winner 2019B.R.A.G. Medallion Honoree 2019Chill With A Book Premier Award 2019Joe Falcon has a problem. He’s bored. He needs a new purpose, and a new adventure.When an unidentified vessel appears beyond Jupiter, both Earth and Mars begin a frantic race to claim it, aware that whichever planet succeeds might in so doing achieve advantage over the other. But who should they send?Joe would never consider himself the ‘right’ person. Drifting around the Asteroid Belt in a converted freighter, working as a surveyor and miner with a crew of oddballs and misfits who, like himself, are running away each from his or her own private demons, he cannot think of a single good reason why he should be the chosen one. But how could he not go?When the surveyor Butterball rendezvous with the Visitor, Joe discovers a ship so immense, exploring its thousands of square kilometers of decks is unrealistic. As the alien vessel responds to his presence in wondrous yet frightening ways, not a trace of its inhabitants can be found. Virtually everything Joe and his team sees defies explanation, and little is what it appears to be. Joe soon realizes he and his crew are expendable and cannot take anything or anyone at face value, including the alien ship’s owners. And all the time, the crew is being watched and studied. Then humanity learns that this wondrous spacecraft is not their real problem.Never would Joe have imagined it would fall to him to make the decision that would alter the destiny of two worlds, launching humankind onto the path to a glorious future, or to extinction.Falcon’s Call is an action packed dive into the unknown, written in the style of the great, classic, science-fiction stories. If you like surprising plot twists, compelling characters and a hero who actually cares, you must read this new novel by Mike Waller.Pick up your copy of Falcon’s Call today, and let your imagination carry you on Joe Falcon’s voyage.

Offers 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.

A very accessible introductory text, offering an exceptionally broad coverage of the politics of the Russian Federation. It examines the limited extent to which economic and social groups have been able to benefit from the fall of the communist order and to withstand the increasing authoritarianism of Putin's presidency. -- .
