Frequency analysis is often referred to as Fourier analysis but is that really true? The foundation is based on stationary and "Fourier signals." What happens if that is not the case? Modern FFT signal analyzers use very sparse sampling that is correct according to Shannon but what will happen when using time domain analysis. Many of the myths and frequent questions will be answered using a "user perspective" and rules of thumb will be given together with good methods to avoid large errors. After attending this session, a much better understanding in regards to pitfalls and proper methodology will be the outcome.

Abstract It is well known that spark ignited engine performance and efficiency is closely coupled to fuel octane number. The present work combines historical and recent trends in spark ignition engines to build a database of engine design, performance, and fuel octane requirements over the past 80 years. The database consists of engine compression ratio, required fuel octane number, peak mean effective pressure, specific output, and combined unadjusted fuel economy for passenger vehicles and light trucks. Recent trends in engine performance, efficiency, and fuel octane number requirement were used to develop correlations of fuel octane number utilization, performance, specific output. The results show that historically, engine compression ratio and specific output have been strongly coupled to fuel octane number.

Abstract This paper summarises the history of Rochdale Motor Panels and Engineering Ltd. (RMP), established in England after the Second World War, from its origins as a small car-repair business though to the manufacture of sports coupés utilising an innovative glass-fibre monocoque construction. The political climate which caused RMP and similar undertakings to develop and flourish in the 1950s and 60s is explained together with details of the three men who had the defining influence on the cars that were created. Products, including aluminium-bodied cars, produced primarily for racing, are described, leading into the introduction of glass-fibre construction which enabled a profitable transition into higher volume body and chassis manufacture, and ultimately completely assembled cars.

This book covers one and a quarter century of the automobile, conceived as a cultural history of its technology, aimed at engineering students and all those who wish to have a concise introduction into the basics of automotive technology and its long-term development . Its approach is systemic and includes the behavior of drivers, producers, nonusers, victims, and other "stakeholders" as well as the discourse around mobility. Nowadays, students of innovation prefer the term co-evolution, emphasizing the parallel and mutually dependent development of technology and society. This acknowledges the importance of contingency and of the impact of the past upon the present, the very reason why The Evolution of Automotive Technology: A Handbook looks at car technology from a long-term perspective. Often we will conclude that the innovation was in the (re)arrangement of existing technologies. Since its beginnings, car manufacturers have brought a total of 1 billion automobiles to the market.

Bernhard Rieger
At the Berlin Auto Show in 1938, Adolf Hitler presented the prototype for a small, oddly shaped, inexpensive family car that all good Aryans could enjoy. Decades later, that automobile—the Volkswagen Beetle—was one of the most beloved in the world. Bernhard Rieger examines culture and technology, politics and economics, and industrial design and advertising genius to reveal how a car commissioned by Hitler and designed by Ferdinand Porsche became an exceptional global commodity on a par with Coca-Cola. Beyond its quality and low cost, the Beetle’s success hinged on its uncanny ability to capture the imaginations of people across nations and cultures. In West Germany, it came to stand for the postwar “economic miracle” and helped propel Europe into the age of mass motorization. In the United States, it was embraced in the suburbs, and then prized by the hippie counterculture as an antidote to suburban conformity.

Writing in 1901, the futurist H. G. Wells predicted not only the decline of railways but the rise of the “motor truck” – a term unfamiliar to most readers at that time. Wells foresaw “large carrier companies” with fleets of horseless vehicles “to carry goods in bulk or parcels.” At the turn of the 20th century, colossal railroad companies ruled long-distance “land locomotion.” And the prospect of commercial life without draft horses seemed about as likely as Martians invading Earth – a story Wells had published four years earlier. But only one year later, ironically in a horse barn near a Chicago tannery, an ex-bicycle maker named Magnus Hendrickson began assembling Wells’ vision. This would become a decades-long undertaking to divine, design, build, continuously improve and ultimately perfect what makes a truck a truck – not simply a bigger car. Along the way, Magnus and his sons founded The Hendrickson Motor Truck Company, which in 2013 celebrated 100 continuous years of operations.

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.

Due to current economic conditions, aircraft companies of today are experiencing an increasing need for their fleets to maintain safe operation beyond their original design life. The result is a growing percentage of aging aircraft that must maintain their airworthiness by utilizing standard methods of inspection and repair. In order to determine if potential continuing airworthiness problems exist for the general aviation fleet as a function of the aging process, the Federal Aviation Administration (FAA) established a research program at the National Institute for Aviation Research (NIAR), Wichita State University, to conduct destructive evaluations on four aged general aviation airplanes. The intent of the program is to provide insight into the condition of a typical aged airplane and to see if a correlation exists between its maintenance history and current condition from a safety of flight perspective.

The fatigue behavior of Hilok fastener joints under constant amplitude loading has been investigated experimentally. The effects of load transfer in an unbalanced joint configuration was characterized in terms of a stress severity factor relative to the open-hole configuration. The experimental data indicates that the clamp-up forces dominate the performance of fastener joints with the open-hole fatigue life being the lower bound at the stress levels investigated. The failure modes were observed to transition from a net-section type failure across the minimum section to a fretting induced failure at some distance from the hole. The experimental data has been used to develop stress severity factors to be used as a measure of the fatigue quality of the fastener joints.

This book, by Bill Holder, discusses the "Lost Fighter" turbojet and turboprop propulsion systems of the exciting jet fighter era in the United States since the mid-1940s. Until now, very little has been published about these fascinating fighter activities that, for a variety of reasons, did not reach fruition. Covering fighters that did not reach beyond an artist's concept stage, to those that were cancelled after an evaluation of flight capabilities, to others that were cast aside after losing a fly-off competition, this book makes use of previously unpublished, primary-source material. It provides a coherent picture of U.S. jet fighter development and evolution. This book also includes hundreds of photos, drawings, and illustrations of the many "Lost Fighters."
