The magnetic levitation train, also known as a maglev train, operates on the principle of magnetic repulsion and attraction. Instead of using traditional wheels and tracks, maglev trains use powerful magnets to levitate and propel the train forward. The basic working principle involves two key components: electromagnets and guideway tracks. The train itself contains powerful electromagnets in its undercarriage. These electromagnets are used to create a magnetic field that repels against the guideway tracks, effectively lifting the train and allowing it to levitate at a small distance above the track. This eliminates the friction experienced in traditional wheel-based trains, allowing for higher speeds and smoother rides. In addition to levitation, the same electromagnets are also used for propulsion. By constantly adjusting the polarity of the magnets in the guideway tracks and the train, the maglev system can create a continuous push and pull effect, propelling the train forward. Overall, the magnetic levitation train relies on the principles of electromagnetism and magnetic repulsion to achieve levitation and propulsion, resulting in a fast, efficient, and environmentally friendly mode of transportation. #Innovation #RailwayTechnology

The PCT (Fig. 28) was published with the examiners' report: https://lnkd.in/ecjFVpem https://lnkd.in/eAyiEmkT #resship. The patent was granted: https://lnkd.in/gFesNkZY https://lnkd.in/euXutsVY. The patent reveals a comprehensive universality for fluid machines serving different purposes. The invention's scope encompasses a number of diverse fields, including hull-integrated propulsion systems, #resship, rotary wing aircraft, wind turbines, and water turbines. Figure 28 depicts a propulsion system for a large container ship comprising four turbines with a novel type of rotary wing kinematics. The propulsion system is protected by a symmetrical stub wing, which features an inlet for the flow on the pressure side. A flow guide within the wing stub ensures that the morphing blade profiles of the rotor are impinged by a counter flow. The outer shell provides a protective barrier for the rotor, preventing it from being affected by the external flow generated by the ship's cruising speed. This ensures that there is no undesirable overlap between the cruising and circulating speeds. The introduction of a counter flow system serves to prevent the creation of rotational flow within the inner shell of the stub wing. Furthermore, the negative influence of rotor blade impingement caused by the vessel's travelling speed can be excluded. An exit opening for the flow is provided at the suction side of the wing stub. The suction sides of the asymmetric wing profiles are variable, featuring two reversing points aligned on a diameter perpendicular to the direction of travel. These points can be rotated within a circle of 360 degrees in a matter of seconds, enabling the ship to be steered in a different direction. The container ship has a hull-integrated propulsion system comprising four propulsion units integrated into a drive channel extending from the bow to the stern of the ship. #carbonneutral #climatechange #shipping #logistics #sustainable #respropulsion #shipbuilding #logistics #containership #resflushedpropulsion www.res-institute.com

On October 29 and 30, 2024 MTEC/ICMASS 2024 took place in Trondheim - and we were represented by 7 colleagues giving lectures there. For all those who did not make it to Norway or would like to read the papers presented, we introduce them here.   Number 7, provided by Igor Bačkalov from DST - Development Centre for Ship Technology and Transport Systems: Small inland waterways offer considerable capacity for modal shift of cargo transport. Revitalization of smaller inland waterways, however, may require new vessel designs as most of the existing small vessels are outdated and incompatible with the present state of the technology development and the current commercial and regulatory requirements. This paper "Impact of automation and zero-emission propulsion on design of small inland cargo vessels" https://lnkd.in/d66XRtpU investigates the possibilities for modernization of small inland vessel designs and offers a systematic analysis of impact of "automation" and "zero-emission propulsion technology" on reference designs of standard European inland cargo vessels of CEMT classes I, II, III, and IV. The adopted level of automation enables the vessels to be remotely operated without human crew onboard, whereas the adopted zero-emission propulsion concept is based on electrification of the powertrain. The paper identifies the impacts of the modernization on general arrangement, cargo capacity, safety, structural design, etc. and indicates the vessel classes which could be the most promising candidates for the design of a future small autonomous inland ships.

New MGP Technology Enhances Aerodynamics At Auburn Hills Campus Stellantis has announced a major investment of $29.5 million to upgrade its wind tunnel facility at the Chrysler Technology Center (CTC) in Auburn Hills. The project focuses on innovative Moving Ground Plane (MGP) #technology. This enhancement is designed to improve the aerodynamics of the company’s #electricvehicles (EVs), a crucial factor for extending their driving range and overall efficiency. The new MGP technology allows for precise measurement and reduction of airflow resistance from wheels and tires, contributing up to 10% of total aerodynamic drag in real-world #driving conditions. Optimizing aerodynamic performance is essential for increasing #EV range, which can lead to smaller #battery sizes. This reduction in battery size can result in lower costs and reduced #vehicle weight, benefiting customers. “Range is a core consideration for customers who are transitioning to cleaner mobility through battery power,” said Mark Champine, Senior Vice President and Head of North America Engineering Technical Centers. “This investment is critical because, by reducing drag, we enhance electric-vehicle range and improve the overall customer driving experience.” The upgraded wind tunnel uses advanced simulation techniques that allow test vehicles to remain stationary while the wheels can move, simulating on-road conditions. This setup enables more accurate aerodynamic testing and faster development cycles for new models. https://lnkd.in/gcW_mitZ

🛩️ Unlike the sleek, advanced, and futuristic appearance of eVTOL aircraft, regional electric aircraft offer the potential to be a quieter game changer. These efficient and robust fixed-wing aircraft, equipped with electric or hybrid-electric propulsion systems, combine the benefits of traditional fixed-wing designs with the advantages of electric propulsion technologies. 🛩️ Researchers from Konkuk University in South Korea and Maxim Tyan from New Uzbekistan University have explored the feasibility of such aircraft in the near future, examining the impact of technology maturity and uncertainties during the conceptual design phase.

China’s 1,000 km/h Maglev Train Successfully Passes Demo Test China has successfully completed a demonstration test of its ultra-high-speed (UHS) maglev train, which can reach speeds of up to 621 miles per hour (1,000 km/h), making it the fastest train in the world. The test, conducted in Shanxi province, marks a significant milestone for the advanced transportation system. What Is Maglev? How Magnetic Levitation Works Maglev, short for magnetic levitation, is a technology that uses magnets to lift and propel objects, like trains, without touching the ground. It works by using powerful magnets to create magnetic fields that repel or attract each other, allowing the object to float and move smoothly. This eliminates friction, making maglev systems very fast and efficient. China’s UHS Maglev System https://lnkd.in/erHfiTug
