48-Volt Developments

2015-11-09

Development of higher-voltage electrical systems in vehicles has been slowly progressing over the past few decades. However, tightening vehicle efficiency and emissions regulations and increasing demand for onboard electrical power means that higher voltages, in the form of supplemental 48 V subsystems, may soon be nearing production as the most cost-effective way to meet regulations. The displacement of high-wattage loads to more efficient 48 V networks is expected to be the next step in the development of a new generation of mild hybrid vehicles. In addition to improved fuel economy and reduced emissions, 48 V systems could potentially save costs on new electrical features and help better address the emerging needs of future drivers. Challenges to 48 V system implementation remain, leading to discussions by experts from leading car makers and suppliers on the need for an international 48 V standard. Initial steps toward a proposed standard have already been taken.

Advances in Electric Propulsion

2017-05-18

Aviation propulsion development continues to rely upon fossil fuels for the vast majority of commercial and military applications. Until these fuels are depleted or abandoned, burning them will continue to jeopardize air quality and provoke increased regulation. With those challenges in mind, research and development of more efficient and electric propulsion systems will expand. Fuel-cell technology is but one example that addresses such emission and resource challenges, and others, including negligible acoustic emissions and the potential to leverage current infrastructure models. For now, these technologies are consigned to smaller aircraft applications, but are expected to mature toward use in larger aircraft. Additionally, measures such as electric/conventional hybrid configurations will ultimately increase efficiencies and knowledge of electric systems while minimizing industrial costs.

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.

Allied Aircraft Piston Engines of World War II, 2nd Edition

2019-05-16

Allied Aircraft Piston Engines of World War II, now in its second edition, coalesces multiple aspects of war-driven aviation and its amazing technical accomplishments, leading to the allied victory during the second world war. Not by chance, the air battles that took place then defined much of the outcome of one of the bloodiest conflicts in modern history. Forward-thinking airplane design had to be developed quickly as the war raged on, and the engines that propelled them were indeed the focus of intense cutting-edge engineering efforts. Flying higher, faster, and taking the enemy down before they even noticed your presence became a matter of life or death for the allied forces. Allied Aircraft Piston Engines of World War II, Second Edition, addresses British- and American-developed engines. It looks at the piston engines in detail as they supported amazing wins both in the heat of the air battles, and on the ground supplying and giving cover to the troops.

Chevrolet - Racing?

2000-02-25

The sole published expose of one of racing's most famous secret activities. Originally published in 1972, Chevrolet-Racing? reveals the inside story of Chevrolet's early surreptitious involvement in racing, from 1957-1970. This re-issue of the collector's classic tells the fascinating story of how, from 1957 to 1970, Chevrolet probably acquired more successes and more technical knowledge of high performance than any other company in the world. Ironically, they never built a complete, running, race-ready vehicle; nor were ever officially represented at a race, and they never claimed credit for any Chevy products in racing wins, or promoted them in advertising for all that time. How did they accomplish what they did? This book reveals the untold story.

Concepts in Turbocharging for Improved Efficiency and Emissions Reduction

2014-09-22

Legislative requirements to reduce CO2 emissions by 2020 have resulted in significant efforts by car manufacturers to explore various methods of pollution abatement. One of the most effective ways found so far is by shortening the cylinder stroke and downsizing the engine. This new engine then needs to be boosted, or turbocharged, to create the full and original load torque. Turbocharging has been and will continue to be a key component to the new technologies that will make a positive difference in the next-generation engines of years to come. Concepts in Turbocharging for Improved Efficiency and Emissions Reduction explores the many ways that turbocharging will deliver concrete results in meeting the new realities of sustainable, green transportation.
