Drew Robb, freelance writer. In the quest to improve efficiency and per formance of gas turbine engines, manufacturers over the past few decades have steadily altered their designs to increase turbine inlet air temperatures. Although this achieves the desired result, it produces the side ef fect of over heating the blades - and that leads to low cycle fatigue failures. But with oil prices fluctuating and the industr y accepting the reality of the need to reduce carbon emissions, the tendency toward higher turbine inlet temperature continues unabated. This poses considerable challenges for the...
Anne Boorsma, Patrick Fitzsimmons, Dejan Radosavljevic and Stewart Whitworth, Lloyd’s Register ODS Technical Investigations and Analysis Consultancy, UK. Lloyd’s Register ODS has recently been involved with the investigation of a number of vibration and noise related habitability problems aboard feeder containerships of 2000-3000 TEU capacity having all-aft deckhouses; feeder containerships are relatively small vessels that transport car goes to and from large, long-haul container terminals.

Marco Giachi, Eng., Centro Studi Storici di Assomotoracing. Dr. Anthony Massobrio, CD-adapco. One of the most interesting aspects of competition motor racing is watching the gradual development of the vehicles’ technical features over the years, the most impor tant of which provide a snapshot view of leading aerodynamic design thinking of that time. It is impor tant to know the histor y of motor racing technology not only for purely cultural reasons, but for educational reasons too, in order to train young engineers and future aerodynamics designers.

Soonseong Hong, Byungkeun Oh & Yongtae Kim - GM Daewoo Auto. Joel Davison - CD-adapco London, Wondae Jeon & Bongyong Jin - CD-adapco Korea. Whether it is lean manufacturing, six sigma, or some combination, quality improvement is now a primary focus of virtually every manufacturer in the automotive industry. Now that the waste is squeezed out and quality is designed into manufacturing processes, visionary corporations are looking upstream toward the engineering of the product for fur ther gains in quality.

John Mannisto & Joel Davison, CD-adapco Since the first Model T rolled off the famous Ford production lines, the issue of engine cooling has been of prime concern to vehicle designers. Putting an inter nal combustion engine inside a confined space will always provide a ster n engineering challenge, as the explosive combustion of the fuel used to drive the vehicle releases ener gy not only in its kinetic form but, by the nature of the process, as heat. Ensuring this thermal ener gy is dissipated in a way that will not harm the components “under the hood” is essential to ensure that your...
James Ippolito, Dejan Matic & Joel Davison, CD-adapco. With increasing environmental concer ns and rising oil costs, fuel cells are attracting great interest as a por table power source for transpor tation and power generation applications as a cleaner and cheaper alter native to combustion based systems. In recognition of this, CD-adapco in par tnership with the Depar tment of Ener gy’s Pacific Nor thwest National Laborator y (PNNL), has developed a new Exper t System, es-sofc, which is playing an impor tant role in optimizing SOFC (Solid Oxide Fuel Cell) design. This ar ticle highlights...
2008 was a tough year for the auto industry and 2009 is likely to be even tougher if economic predictions prove to be correct. Without exception, auto companies and suppliers are looking harder than ever to improve productivity and cost effectiveness in their product development processes. Dynamics 30 - Read more...
Stepan Zdbinsky, Aeronautical Research and Test Insititue, Czech Republic Fans of motorsport increasingly want to get a taste of what it feels like to go bumper to bumper with other race cars in a competitive environment. While the dream of owning a top sports car might be beyond the reach of the average armchair racer, an increasing number of companies offer the general public a chance to feel the adrenalin a high power car and a strip of tarmac brings, allowing clients to try out a days racing without having to invest large sums of money.

Dejan Matic - CD-adapco. Formula 1 is the world largest annual sporting event with over one billion cumulative viewers in 184 countries watching races across four continents. In the world of speed where fractions of second determine the dif ference between the first and last, the competition takes place not only at the race track but in the factor y as well. Branded with the name that por trays the vision of racing excellence, Formula 1 became the leading arena for development and testing of advanced automotive technologies. Dynamics 30 - Read more...
