F1 Car Project Kenji Nakajima 3B Aerodynamics Drag (Air Resistance) The force acting opposite to the relative motion of any object moving with respect to a surrounding fluid (in this case air). Drag Coefficient The measure of drag of an object. Drag Profile The sum of the surface friction drag and the form drag for a body moving subsonically through a fluid Friction The resisting force of surfaces to a moving object Lift The component force of fluid passing through an object that is perpendicular to the oncoming flow direction. Aerodynamics Weight - The force on an object due to gravity. Grip Force - The term describing the total cornering envelope of a race car by the friction component of the tire Downforce - The downwards thrust created by the aerodynamic characteristics of a car. Traction - The force used to generate motion between a body and a tangential surface Bernoulli Effect The increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy. Mechanical Terms Kammback - A Kammback is a car body style that derives from the research of the German aerodynamicist Wunibald Kamm in the 1930s. A car body style that includes a smooth top back that ends at the tail. This body style reduces drag Car Exterior - Exterior detailing involves cleaning and restoring or exceeding the original condition of the surface of the car's finish, chrome trim, windows, wheels, and tires, as well as other visible components on the exterior of a vehicle. Defines how aerodynamic a car is. How fast it goes. Rear Spoiler Fin - A spoiler is an automotive aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across a body of a vehicle in motion, usually described as turbulence or drag. Wing - A wing is a type of fin that produces lift, while moving through air or some other fluid.

Automotive Design Culture: Aesthetic Trends Originated in Technology
F2004U060 AUTOMOTIVE DESIGN CULTURE: AESTHETIC TRENDS ORIGINATED IN TECHNOLOGY Liamadis, George*, Tsinikas, Nikolaos Faculty of Technology, School of Architecture, Aristotle University of Thessaloniki, Greece KEYWORDS - Design, Styling, Trends, Technology, Society ABSTRACT – Ever since the Futurist’s Manifesto, first to see the inner beauty of speed and progress symbolized in the form of early automobile’s mechanical parts, automotive history has often experienced paradigms of technological breakthroughs grown popular to establish aesthetic trends. The car, this highly influential cultural icon of the last century, has often drawn its stylistic inspiration in the product’s technological nature, in the attempt to express visually human’s inherent need for more power, for “better and faster”. Great pipes on early racing cars (1910’s), recalling images of “snakes with explosive breath”, had soon given their place in a new formal language, an aesthetic refinement known as streamlining (1930’s). The expressive force of streamlining, made it synonymous with ‘design’, sculptural intensity and ‘vigorous motion’ even when standing still. It provided an effective visual metaphor for progress, which soon became a formal topos and established an aesthetic trend later extended to a whole series of industrial products, often alien to the idea of motion. Aircraft-referential tailfins on American cars of the 50’s, took automotive styling into the supersonic age, expressing the power of flight and the optimism of the post-war period. The 1973 oil crisis brought up an automotive culture, which shifted the goal from maximization of speed to the optimization of effectiveness. Within this context, streamlining has retained its significance, now justified in terms of ecology and environmental politics.

Introduction All lines of thoughts, considerations, and analysis to increase flight performance, or to say in a more generalised way, to achieve air superiority, leads ultimately to placing special attention on power plants for aircraft and missiles. Herein, there exists a certain interaction, which on the other hand only allows a starting point from the present know-how of power plants to be able to continuously create better aircraft. A key prominence goes to research and development that addresses the subject matter of power plants. The awareness of this demands a certain amount of fortitude, to see far into the future in order to perceive the ultimate goal and to plot a clear path for achieving this goal. During this process of research and development, it is necessary to establish way-points from time-to-time, for assessing the data thus far obtained and to incorporate the results into the overall effort. Currently, there are three major constituents acknowledged, which outline this state-of- the-art technology. The piston engine This group encompasses the entire first part of aviation history, from the very beginning, which used a modified automobile motor, up to today’s severe demands on flight performances, which can only be increased further uneconomically or with an unjustifiably great effort.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. This paper reviews the history of automotive technology development and human factors research, largely by decade, since the inception of the automobile. The human factors aspects were classified into primary driving task aspects (controls, displays, and visibility), driver workspace (seating and packaging, vibration, comfort, and climate), driver’s condition (fatigue and impairment), crash injury, advanced driver-assistance systems, external communication access, and driving behavior. For each era, the paper describes the SAE and ISO standards developed, the major organizations and conferences established, the major news stories affecting vehicle safety, and the general social context. The paper ends with a discussion of what can be learned from this historical review and the major issues to be addressed. A major contribution of this paper is more than 180 references that represent the foundation of automotive human factors, which should be considered core knowledge and should be familiar to those in the profession.

Adolf Hitler Stole the Idea for the Iconic Volkswagen Beetle from a Jewish Engineer and Had Him Written out of History, a Historian Has Sensationally Claimed
Adolf Hitler stole the idea for the iconic Volkswagen Beetle from a Jewish engineer and had him written out of history, a historian has sensationally claimed. The Nazi leader has always been given credit for sketching out the early concept for the car in a meeting with car designer Ferdinand Porsche in 1935. His idea for the Volkswagen - or 'people's car' - is seen by many as one of the only worthwhile achievements of the genocidal dictator. Bug's life: Josef Ganz and his design, which Adolf Hitler saw at a car show in 1933, not long before he made his sketches for Ferdinand Porsche Gorgeous curves: One of Ganz's early drawings, which have been left buried in the past for many years 'People's car': Mr Ganz with one of his designs that author Paul Schilperoord says led up to the development of the Volkswagen But Paul Schilperoord's book, The Extraordinary Life of Josef Ganz - the Jewish engineer behind Hitler's Volkswagen, may change that forever. Hitler stipulated that the vehicle would have four seats, an air-cooled engine and cost no more than 1,000 Reichsmarks - the exact price that Mr Ganz said the car would cost. Three years before Hitler described 'his idea' to Mr Porsche in a Berlin hotel, Mr Ganz was driving a car he had designed called the Maikaefer, or May Bug. The lightweight, low-riding vehicle looked very like the Beetle that was later developed by Mr Porsche, who is still considered the foremost car designer in German history. Jewish inventor Mr Ganz had been exploring the idea for an affordable car since 1928 and made many drawings of a Beetle-like vehicle.
