Investigation into High-Speed/Super-High Speed Grinding
Advanced Materials Research, 2011Abrasive machining is a widely employed finishing process for different-to-cut materials such as metals, ceramics, glass, rocks, etc to achieve close tolerances and good dimensional accuracy and surface integrity. High speed and super-high speed abrasive machining technologies are newest developed advanced machining processes to satisfy super-hardness ...

AIAA Atmospheric Flight Mechanics Conference and Exhibit, 2005
Current takeoff mass of a long-distance aircraft is made up of approximately 1/3 aircraft body, 1/3 fuel, and 1/3 payload. The aircraft engine needs expensive aviation fuel. The passenger-transport aircraft cannot exceed the speed of sound. The “Concorde” history shows that the conventional passenger supersonic aircraft is unprofitable.

In World War II when Spitfires and Mustangs and Messerschmitt 109s and other aeroplanes of that category were quite common, we were all aware of the troubles that these particular aeroplanes got into when starting to dive. When getting up to around 80 per cent of the speed of sound, the aeroplane starts shaking, buffeting we call it; some of them lost ...

High speed rail systems are being designed and built all over the world. Today, China alone accounts for approximately half of the world’s rail transport turnover, and the country plans to construct around 30,000 Km of new lines (double the current total in Italy) in the near future – most of which for very high speed trains.
