The recent successful test of the Hyperloop One is proof that the future of transport is at our fingertips. The near-supersonic transit concept used magnetic levitation for the first time on the ‘DevLoop’ test track in a vacuum environment. Co-founder Shervin Pishevar claims that by achieving full vacuum, they’ve essentially created a sky in a tube as if traveling 200 000 feet in the air.
The latest test showed speeds of 308 km/h (192 mph) on the 500-meter (1,640-foot) test track in Nevada where all system components functioned as intended. The next phase is Continue reading →
Deep hole drilling (DHD) is a stress measurement technique used in engineering materials and components to measure locked-in and applied stresses. The process measures residual stresses at a microscopic level with penetration of over 750 millimeters (30 in), without destroying the original component.
Advances in engineering technology have given common CNC machining centres gun drilling ability up to a certain depth-diameter ratio. Roundness and surface finish are among considerations. Common applications of deep hole drilling and machining processes include Continue reading →
Technology is at the point where talking about a flying car should come as no surprise. This can be attributed mainly to the new lightweight material, improved batteries, advanced computer technology and controls. According to reports, DeLorean Aerospace is in the process of developing a two-seater VTOL aircraft called the DR-7. This puts Paul DeLorean in a whole new category along with Airbus, Uber, Darpa and the likes of Larry Page.
The DeLorean is best remembered for the time-traveling sports car from Back to the Future films piloted by Doc Brown. Who would have thought his quote would Continue reading →
Over the past few decades, abrasive waterjet cutting have evolved significantly. From a relatively crude cutting tool in the early 1980’s to a more sophisticated machine tool used in various sectors ranging from aerospace, mining to the food industry. This evolution is mainly due to better material development, more efficient system design, improved control of the waterjet tool and the progression to achieve higher pressure. Continue reading →
The USS Gerald R. Ford (CVN-78) is Marine Engineering at its best. It houses more than 4 500 crew members and weighs in at 90 000 tons. With a $13 billion price tag, it’s the most expensive and most advanced warship ever built. It certainly sets the bar extremely high.
Christened in November 2013 and scheduled to be commissioned this year, these super-carriers are expected to be in service until 2065. They are also set to replace some of the Navy’s existing Nimitz-class carriers.
Both classes have a similar-looking hull but the Ford class is miles ahead with new technical and technological innovations. Designed to improve operating efficiency and reduce operating costs, the USS Gerald R. Ford also requires fewer crew; about 600 to be more specific. It’s estimated to save $4-5 billion on operational expenditure making it extremely cost effective in comparison. Continue reading →
