SpaceX is installing the first Raptor engine into the Starhopper. There is video and pictures of the Raptor engine beside the Starhopper. Vivian Okoy shared a tweet with a picture of the Raptor engine. The Raptor engine has nearly twice the power of the current SpaceX Merlin engine. There will be three Raptor engines used …
US Special Operations have built prototypes of the TALOS exoskeleton. It is designed to shield commandos from gunfire when they are in heavy urban combat. This special situation exoskeleton system will be the first system used in combat. In five years there will be lower body exosuits to help soldiers carry their heavy loads. US …
China has carbon nanotube bundles in the lab that are 20 times stronger than kevlar. They are trying to scale them up for mass production. If they succeed in mass producing tons of this material then what has been impossible become possible engineering. Superstrong materials were the key part of molecular nanotechnology speculation. Carbon nanotube …
Elon Musk wants the new Tesla Roadster is to beat gas sports cars on every performance metric by far and without exceptions. * faster from 0 to 60 mph * faster on the quarter mile * better braking, cornering and handling * higher top speed. Tesla will have 10 small rocket thrusters around the car. …
The US trucking industry is being pressured to deal with diesel emissions. California would require that NOx emissions from medium- and heavy-duty trucks be cut by about 90 percent relative to today’s cleanest diesel. India and China mostly do not use diesel cleanup systems, so their NOx emissions are about 10 times higher. China and …
Fan Xuejun, head of Institute of Mechanics’ [hypersonic] “scramjet” division – focused on using high vehicle speed to compress incoming air forcefully before combustion – was lead scientist for the hypersonic project. Fan told the South China Morning Post that a hypersonic engine plant would make engines in a range of models for customers in …
Robert Bosch GmbH said its engineers have developed a new diesel-exhaust system that cuts emissions to 1/10th the legal limits taking effect in 2020 and can help automakers avoid potential driving bans in Europe that threaten to doom the engine technology. Automakers have relied on diesel to help the industry meet limits on CO2 emissions, …
China has designs for a mass production hypersonic engine for low-cost planes or spacecraft capable of traveling five times faster than the speed of sound. The plant that would be built in Hefei, in China’s eastern Anhui province, could give the country an edge over the United States and Russia in the race to achieve …
Vanadium is a largely obscure metal often used in making steel. It retains its hardness at high temperatures, so it’s ideal for making drill bits, engine turbines and other parts that generate heat. In the oilsands, Vanadium is one of the metals that comes out of the ground with bitumen. The concentration is quite low: …

Video of Chengdu J-10 and Shenyang J-11 jets flying low over snow-capped mountains was posted on the People’s Liberation Army’s official website on Monday. The jets are part of China’s fleet of third-generation lightweight multi-role fighter aircraft and are powered by Russian AL-31F engines. A Shaanxi Y-9 transport aircraft was shown taking off and landing …
