Enlarge / A 2015 Ram 1500, one of the models affected by this recall. (credit: FCA) Dodgy software code controlling side airbags and safety belt pretensioners is responsible for a recall affecting more than a million Ram pickup trucks. On Friday, Fiat Chrysler Automobiles (FCA) announced that it will be recalling Ram 1500 and 2500 trucks (model years 2013 to 2016) and Ram 3500 trucks (model years 2014 to 2016) beginning in June in order to rectify the problem. The software error, which could prevent side airbag deployment and belt pretensioning in cases where a vehicle rolls over following an underbody impact—say, hitting road debris or something when off-roading—has already been implicated in one death. Although the code has not been conclusively fingered as the culprit, FCA says it is issuing the recall proactively. A similar issue forced General Motors to recall more than 4 million vehicles in 2016. Read 1 remaining paragraphs | Comments

Ram is recalling more than a million trucks for faulty software
According to Reuters, Boeing has hired Norsk Titanium AS to print titanium parts for its 787 Dreamliner, paving the way to cost savings of $2 million to $3 million for each plane. The 3D-printed metal parts will replace pieces made with more expensive traditional manufacturing, thus making the 787 more profitable. From the report: Strong, lightweight titanium alloy is seven times more costly than aluminum, and accounts for about $17 million of the cost of a $265 million Dreamliner, industry sources say. Boeing has been trying to reduce titanium costs on the 787, which requires more of the metal than other models because of its carbon-fiber composite fuselage and wings. Titanium also is used extensively on Airbus Group SE’s rival A350 jet. Norsk worked with Boeing for more than a year to design four 787 parts and obtain Federal Aviation Administration certification for them, Chip Yates, Norsk Titanium’s vice president of marketing, said. Norsk expects the U.S. regulatory agency will approve the material properties and production process for the parts later this year, which would “open up the floodgates” and allow Norsk to print thousands of different parts for each Dreamliner, without each part requiring separate FAA approval, Yates said. Norsk said that initially it will print in Norway, but is building up a 67, 000-square-foot (6, 220-square-meter) facility in Plattsburgh in upstate New York, where it aims to have nine printers running by year-end.

An anonymous reader quotes a report from Hacked: Earlier this month Hacked reported that a draft version of the much expected EmDrive paper by the NASA Eagleworks team, had been leaked. Now, the final version of the paper has been published. The NASA Eagleworks paper, titled “Measurement of Impulsive Thrust from a Closed Radio-Frequency Cavity in Vacuum, ” has been published online as an open access “article in advance” in the American Institute of Aeronautics and Astronautics (AIAA)’s Journal of Propulsion and Power, a prestigious peer-reviewed journal. The paper will appear in the December print issue of the journal. The final version of the paper is very similar to the leaked draft. In particular, the NASA scientists confirm the promising experimental results: “Thrust data from forward, reverse, and null suggested that the system was consistently performing at 1.2 +/- 0.1 mNkW, which was very close to the average impulsive performance measured in air. A number of error sources were considered and discussed.” The scientists add that, though the test campaign was not focused on optimizing performance and was more an exercise in existence proof, it is still useful to put the observed thrust-to-power figure of 1.2 mN/kW in context. “[For] missions with very large delta-v requirements, having a propellant consumption rate of zero could offset the higher power requirements. The 1.2 mN/kW performance parameter is over two orders of magnitude higher than other forms of ‘zero propellant’ propulsion, such as light sails, laser propulsion, and photon rockets having thrust-to-power levels in the 3.33–6.67 uN/kW (or 0.0033–0.0067 mN/kW) range.” In other words, a modest thrust without having to carry fuel can be better, especially for long-distance space missions, than a higher thrust at the cost of having to carry bulky and heavy propellant reserves, and the EmDrive performs much better than the other “zero propellant” propulsion systems studied to date.

AmiMoJo quotes a report from NHK WORLD: Japanese electronics maker Panasonic says it will stop making LCD panels for televisions, giving way to fierce price competition. The pullout from TV LCD manufacturing follows the company’s withdrawal from plasma TV production 3 years ago. They say they will continue to manufacture LCD panels at the plant for products other than televisions, such as medical equipment and cars. They say the company will keep making Panasonic-brand televisions, using panels supplied by other manufacturers. After Panasonic pulls out, Sharp and its Taiwanese parent firm Hon Hai will be the only producer in Japan. Read more of this story at Slashdot.
