But one of the biggest sticking points wasn’t so much to create an aircraft that could fly fast, but rather to design one that could also fly slowly. The STRATOFLY design came with plenty of technological challenges. The goals are aligned with national, international and business priorities. The EU is funding numerous research initiatives covering a range of fundamental technologies, including hydrogen-related ones, to make aviation safe, efficient and clean. While these technologies might take many decades to enter service, it’s important to dream big now, according to scientists. Still, in the worlds of civil aviation and research, ambitious ideas persist to make faster and cleaner airplanes. ![]() Recent EU regulatory initiatives, including a new law to cut aviation emissions, have highlighted the political skepticism in Europe by limiting incentives for supersonic commercial flights. In the meantime, the political appetite in the EU for supersonic passenger air travel has waned in large part because of environmental concerns, not least noise and emissions of pollutants that cause climate change. The project focused on innovative ways of powering an aircraft able to carry 300 passengers. STRATOFLY designed a prototype in the form of a computer model for a hydrogen-fuelled hypersonic plane. But I’m sure that I will see a hypersonic airliner in my lifetime.” ![]() “Maybe we’re not ready yet for Mach 8 right now. “It’s going be a real challenge,” said Nicole Viola, who coordinated STRATOFLY and is a professor at the Polytechnic University of Turin in Italy. STRATOFLY, which ran from 2018 to 2021, built on three previous EU research projects in the field. ![]() That’s what the EU-funded STRATOFLY project proposed: a Mach 8 airliner - a hypersonic aircraft that can go at least 9,500 kilometers (5,900 miles) per hour, or about eight times the speed of sound. So the question arises: will people one day be able to count on flying from Paris to New York in less than an hour without contributing to global warming? Sky-high ambitions The following is captured image of safety and disinfection campaign videos currently playing on our products installed in Seoul Metro.Traditionally designed for efficiency and safety, passenger planes are now increasingly being developed with climate neutrality in mind as well. In addition, content suitable for each customer and site is uploaded easily and conveniently via this platform. Via the IoT platform we developed, all WeClean products around the world are monitored in real time, and the disinfectant spraying cycle is also controlled remotely. The fact that cleaning alone reduces germs can also be seen in the guidelines of health organizations such as WHO.Īs an automatic sterilization cleaning product exclusively for handrails, with 99.99% sterilization effect proven by numerous actual field test reports and regular cleaning function that does not require additional beautification personnel, WeClean is also a smart device equipped with IoT function. WeClean’s patented 3-tier cleaning roller rotates in the “reverse & forward” direction according to the rotation of the handrail to clean every nook and cranny of the surface. In addition, the trouble of cleaning the handrail surface every time even after installing the sterilizer is solved with WeClean’s 3-tier cleaning roller. WeClean not only performs the same human spraying and wiping of the disinfectant, but also can set the disinfectant spraying cycle from 1 to 60 minutes, so the handrail can be continuously sterilized throughout the operating time. The photos above show the cleaning staff and staffs manually disinfecting the handrails, the customer contact point, using disinfectant and rags.Īs the number of management targets increases, the problem of management manpower and input time, and the amount of work will naturally increase.Īnd another important point is the continuity of disinfection, which can be said to be a gap in manual disinfection.Īll of these problems can be solved by applying our WeClean.Īll of the WeClean models installed this time are S200G, hybrid premium self-generation type that performs disinfectant spray and UV advanced oxidation process at once. Seoul Metro, which transports an average of 7,469,180 people a day (2019), has been disinfecting and cleaning the escalator handrails 4 times a day since Corona19. Due to the unprecedented COVID-19 pandemic, surface disinfection of many public facilities is mandatory. ![]()
