A team of scientists from the National University of Science and Technology in Moscow has devised a new production method for making aerospace composite parts which gives them a final strength improvement of 15%, compared to that of conventional parts made of materials such as titanium alloys, that are omnipresent and widely-used in the aerospace […]
Read MoreCOMAC (Commercial Airline of Chine) has successfully completed a three-hour test flight for the C919, the country’s first take on narrow-body airliners that is to compete with the omnipresent Boeing 737 and Airbus A320. The C919 has been under flight testing since 2017, but as the first delivery dates approach, the aircraft enters more vigorous […]
Read MoreRocket Lab has announced the successful launch of its 26th Electron mission, which deployed 34 micro-satellites into low-Earth orbit. The highlight of this launch was the retrieval of the returning booster, as capturing and reusing these components dramatically reduces the cost of these otherwise ultra-expensive operations. Roughly 80% of the rocket’s entire worth is actually […]
Read MoreAfter aerodynamics and engine performance, weight is the most important factor that affects the efficiency of an aircraft. Less weight means less fuel used, which can add up to millions in savings. Now, a futuristic cryogenic tank design promises to radically boost the range of hydrogen-powered aircraft The extremely lightweight tank could help clean fuel-cell […]
Read MoreArticle Source: MDPI Rivets play a crucial role in constricting joints on aircraft fuselages and wings, and this has been the case since the early times of aviation. Simply put, aircraft manufacturers cannot use welding for bonding panels together because aluminum isn’t tolerant to heat, riveted joints are stronger, and finally, they are easier to […]
Read MorePalladium prices have exploded in the past decade, going from $5,300/kg in 2008, to $15,600/kg in 2016, $60,000/kg in 2020, and standing at $75,000 per kg right now. The valuable rare metal has been historically used in catalytic converters of cars, but it’s now also required by hydrogen fuel cell technology, an emerging technology that […]
Read MoreThe U.S. Department of Defense, and more specifically, the Strategic Capabilities Office (SCO), has published a press release to inform of the launch of a new program intended to develop a mobile micro-reactor able to deliver 1-5 MW of electrical power for at least three years of continuous operation. SCO will first develop a prototype […]
Read MoreAirbus says the assembly of its first electric-powered aircraft platform is underway, and soon, the first test flight of the EcoPulse demonstrator model will take place. This project was developed in partnership with Daher and Safran, who designed and realized the airframe and hybrid propulsion system, respectively. Airbus has designed the battery, and this is […]
Read MoreSiemens Gamesa Renewable Energy has presented a new record-sized offshore wind turbine named the SG 14-236 DD, which features a rotor diameter of 236 meters (774 ft) and a blade length of 115 meters. The new turbine builds upon the previous 222-meters diameter model, but uses the same technology platform so its production can stay […]
Read MoreUS startup Green Hydrogen International (GHI) has unveiled its plans to build the world’s largest green hydrogen plant. The company is planning to build a 60 GW green hydrogen production facility in South Texas. The project is called Hydrogen City. It will take account of integrated green hydrogen production, storage, and transportation capabilities. The company […]
Read MoreGE Aviation Engine Services Singapore has become the first entity to offer metal additive technology for aerospace components, including aircraft engines. To put this simply, that would be 3D printed metal parts that are custom-crafted to the specific needs of the repair job and embedded or fitted where needed. The idea is to offer custom […]
Read MoreEngineers at the USAF are designing digital twins of older aircraft such as the venerable B-1 Lancer, first introduced almost five decades ago. The heavy bomber and many others of its time were designed on paper blueprints featuring hand-drawn schematics, as the age of computer-assisted design (CAD) hadn’t dawned yet. If you wonder why engineers […]
Read MoreNickel is undergoing a wild pricing ride lately, being one of the most heavily affected metals of the market turbulence caused by the Russian invasion of Ukraine and the resulting sanctions and shortages. The region of Krasnoyarsk in Russia is one of the world’s major production hubs of nickel, so closing that supply tap makes […]
Read MoreResearchers at the Fraunhofer Institute in Germany have developed a novel laser-based system that can be used for precision and energy-efficient welding of construction metals. According to their measurements, the energy requirements of their system are roughly 85% lower than that of conventional welding methods, while the result is also typically of a higher quality […]
Read MoreConcorde was the world’s first supersonic airliner, it entered service in 1976. But the Concorde aircraft was grounded in 2003, three years after the crash of Air France Flight 4590, in which all passengers and crew were killed. But when Concordes were in action, they would often break the sound barrier. Concorde’s window-rattling sonic booms produced enormous sound energy, […]
Read MoreResearchers at the University of Central Florida have developed a new outer shell of layer carbon composite material that acts as an energy exchange medium. To achieve this, the scientists created positively and negatively charged carbon fiber layers and then stacked and attached them in an alternating pattern, essentially forming a supercapacitor. The graphene sheets […]
Read MoreSteelmaking giant ArcelorMittal SA has closed its Ukrainian steel mill on Thursday after facing raw material supply disruptions and increasing risks associated directly with the Russian invasion of the Eastern European country. The company shut down blast furnaces gradually as the supply problems culminated and forced the production to a minimum, but the escalating situation […]
Read MoreScientists at the Nanyang Technological University in Singapore have developed a cost-efficient method to evaluate the quality, physical, and mechanical properties of 3D printed metal parts. This is a very important development for engineers and technicians across all fields, as it could unlock 3D printing technology applications that were previously deemed too risky due to […]
Read MoreA team of researchers at UC Santa Cruz have found a cost-effective and practically feasible way to produce clean hydrogen gas by using water, aluminum, and gallium. Aluminum’s high level of reactivity has been known and well documented for many years, but researchers struggled to find an efficient way to put it into the context […]
Read MoreThe Cornell Fracture group has published the results of an ongoing study on the formation and propagation of fatigue cracks on metals and claims to have identified the mechanism that causes the cracks to grow. Their paper, titled “Atomic Mechanism of Near Threshold Fatigue Crack Growth in Vacuum,” explains that a molecular dislocation happens near […]
