January 2021 Best-of watch: new developments in transportation – CETIM

A hydrogen-powered train, a ship’s propeller made in additive manufacture and a very high speed autonomous train… this new collection of watch notes published by Cetim puts the world of transport in the honor.

Spain has its hydrogen train! The Talgo Vittal-One, the first train of this type developed by the Spanish manufacturer, is functional and will begin its tests in 2021. It is expected to be on the market in 2023.

The Chinese Fuxing train is equipped with a conventional engine, but it is an autonomous train capable of reaching a speed of 350 km/h. On-board systems automation uses the BeiDou satellite geolocation service (BDS), based on 5G technology. Its autonomous driving system enables it to start and run automatically between stations, adjusting its schedule and stopping precisely at the platform. 2718 sensors are used to detect the slightest anomaly.

A vessel driven by additive manufacturing

This time, Naval Group has equipped a ship of the French Navy with a propeller produced in additive metal fabrication. The largest propeller ever produced with this technique, is a first step for the French. Other parts would have to be redesigned to benefit from the manufacturing gains.

New products for our interior

This new collection of watch notes also highlights new features in the building of the future, with the Threespine/ Välinge snap-on system, which guarantees that furniture can be assembled and disassembled without creating a gap between parts and facilitates recycling at the end of its life. Rewarded with an InterzumAward, this device allows panels to be easily, quickly and without tools fixed to each other thanks to a locking tab inserted in a specific machining. This connection creates a continuous joint that ensures the squareness, stability and solidity of the furniture. This invisible and reversible technology is compatible with all types of machinable materials.

Finally, made of 92% copper, the MetalSkin® coating can be applied like a paint at room temperature and can be used to coat all kinds of objects or surfaces with a flexible skin capable of eradicating bacteria, microbes, germs and other viruses. This biocidal treatment destroys 99% of bacteria in 3 minutes and 99.5% of SARS-CoV-2 in 4 hours.
