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.

Gas Turbine Blade Cooling

2018-12-10
Gas turbines play an extremely important role in fulfilling a variety of power needs and are mainly used for power generation and propulsion applications. The performance and efficiency of gas turbine engines are to a large extent dependent on turbine rotor inlet temperatures: typically, the hotter the better. In gas turbines, the combustion temperature and the fuel efficiency are limited by the heat transfer properties of the turbine blades. However, in pushing the limits of hot gas temperatures while preventing the melting of blade components in high-pressure turbines, the use of effective cooling technologies is critical. Increasing the turbine inlet temperature also increases heat transferred to the turbine blade, and it is possible that the operating temperature could reach far above permissible metal temperature. In such cases, insufficient cooling of turbine blades results in excessive thermal stress on the blades causing premature blade failure.

Diagnostics and Prognostics of Aerospace Engines

2018-11-28
The propulsion system is arguably the most critical part of the aircraft; it certainly is the single most expensive component of the vehicle. Ensuring that engines operate reliably without major maintenance issues is an important goal for all operators, military or commercial. Engine health management (EHM) is a critical piece of this puzzle and has been a part of the engine maintenance for more than five decades. In fact, systematic condition monitoring was introduced for engines before it was applied to other systems on the aircraft. Diagnostics and Prognostics of Aerospace Engines is a collection of technical papers from the archives of SAE International, which introduces the reader to a brief history of EHM, presents some examples of EHM functions, and outlines important future trends.

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: 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.

Electric Motors for Hybrid and Pure Electric Vehicles 2015-2025: Land, Water, Air

2014-11-01
The electric vehicle business will approach a massive $500 billion in 2025 with the traction motors segment capturing over $25 billion. Traction motors propelling land, water and air vehicles along can consist of one inboard motor or - an increasing trend - more than one near the wheels, in the wheels, in the transmission or ganged to get extra power. Complex trends in this industry are explained with this updated report, and future winning suppliers are identified alongside market forecasts. The information is especially important as hybrid vehicles may have the electric motor near the conventional engine or its exhaust, and this may mean they need to tolerate temperatures never before encountered in pure electric vehicles. Motors for highly price-sensitive markets such as electric bikes, scooters, e-rickshaws and micro EVs avoid the price hikes of neodymium and other rare earths in the magnets.

Range Extenders for Electric Vehicles Land, Water & Air 2015-2025

2014-10-01
Half the electric vehicle market value lies in larger road vehicles, notably cars, and here the legal restrictions are weaker or non-existent, and range anxiety compels most people to buy hybrids if they go electric at all. Over eight million hybrid cars will be made in 2025, each with a range extender, the additional power source that distinguishes them from pure electric cars. Add to that significant money spent on the same devices in buses, military vehicles, boats and so on and a major new market emerges. Whereas today's range extenders usually consist of little more than off- the- shelf internal combustion engines, these are rapidly being replaced by second- generation range extenders consisting of piston engines designed from scratch for fairly constant load. However, a more radical departure is the third- generation micro turbines and fuel cells that work at constant load.

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.

Hydrogen, The Post-Oil Fuel?

2012-11-01
Hydrogen, energy vector for the future? Or, on the contrary, limited to its current applications in the field of chemistry and refining for decades to come, possibly even until the end of the century? There is much controversy over this issue and two sides to the argument. Advocates of the hydrogen civilization consider that, following a technological revolution hydrogen will play a universal role alongside electricity as a substitute for fossil fuels, especially (but not only) in transport, leading to radical elimination of CO2 emissions. For the skeptics, and even outspoken opponents, hydrogen will remain restricted to its current applications due to the insoluble problems inherent to its generalized use, especially in transport. This book highlights the increasing and inevitable role of "energy" hydrogen – as opposed to chemical hydrogen – in the key sectors of transport and "clean" electricity production.

The Engines of Pratt & Whitney

2010-01-01
This book describes the evolution from piston engines to gas turbines by the engineers who created those engines. Included are hundreds of archival photographs, as well as over a dozen tables listing specifications and applications. The story starts with the founding of the company in the 1920's to provide reliable air-cooled piston engines to the military and to help create coast-to-coast commercial flight service. Pratt & Whitney quickly dominated commercial and military flight in the 1930's - ultimately providing half the horsepower of American engines during WWII. Jack Connors explains how Pratt & Whitney came from behind the competition on developing gas turbines after the war with the debut of the J57, which powered the B-52 in 1952 and later the Air Force Century Series fighters (F-100, F-101, F-102) and the Navy A3D, F4D, and F-8 airplanes.
