When the COVID-19 pandemic is over, the world that we will return to will be nothing like the one we were used to living in. One of the industries that are currently taking the most damage, and at the same time is expected to change fundamentally in the post-coronavirus age, is aviation. There’s a lot […]
Read MoreAn airplane needs to be strong yet lightweight, with some parts requiring high rigidness and others needing to be pretty flexible. As one can easily deduce, an aircraft manufacturer would need to use a wide array of different materials on a flying model, and this is indeed the case. Today, we see steel, aluminum, and […]
Read MoreWhen you talk about the new aerospace composite parts, engineers usually put layers of carbon composite woven over one another, and they bake this with pressure in a vacuum to create layers as one light and the robust aerospace composite part. These techniques have been around for many years now, and MIT researchers are trying […]
Read MoreModern airplanes are becoming safer every year, but there are still worries about their carbon impact. Also, I think we can agree that planes start to look increasingly like each other – can you really tell the make and model from afar? Airbus, one of the largest and most advanced aerospace companies, will try to […]
Read MoreConventional steelmaking using electric-arc furnaces and decarburization is still very common. However, the internal structure of the cast ingots made with this process isn’t uniform, which negatively affects the qualities of the steel. Sure, a hot method can be used on the ingots to break up the segregated structure, but the structure still won’t be […]
Read MoreMetal extrusion is a process used to create longer objects with a fixed profile by pushing a cylindrical billet inside a closed cavity. The end product is called an extrudate and can have several desired characteristics and qualities. The metal extrusion process was patented by Joseph Bramah and is regularly used to create parts from […]
Read MoreNASA already landed four rovers on Mars: Sojourner, Opportunity, Spirit, and Curiosity. These vehicles taught us a lot about the Red Planet but still couldn’t uncover the truth about life on Mars. NASA’s next rover might be able to do that, thanks to state-of-the-art technology that wasn’t available before. The Agency plans to launch the […]
Read MoreNASA wants to establish a permanent base on the Moon, and they need Caterpillar to help them with the mining operations. The two have a long record of successful collaborations, but this time we’re not talking about developing robotic drills for taking soil samples, but for the actual excavation and mining of the lunar surface. […]
Read MoreRolls-Royce is one of the largest manufacturers of aircraft engines in the world. However, like most companies that work on engines that use fossil fuels, it faces increased public backlash. Airplane engines produce a lot of CO2, which warms the planet ever so slightly. Luckily, they already work on electric airplanes. Their prototype is only […]
Read MorePipe Schedule (SCH) is a standard that measures the nominal wall thickness of a pipe, given by the ANSI / ASME B36.10M standard for Stainless Steel Pipe dimensions, and API 5L standard for seamless and welded steel pipes. The pipe schedule number is non-dimensional and depends on the nominal pipe size, internal pipe working pressure, […]
Read MoreScrap metal is unavoidable in any manufacturing process, but it is also a costly part of it. Sure, most scrap metal is recyclable, but to make it into a new piece, the factory needs to invest in more labor time and an entirely new manufacturing process. Reducing scrap metal is crucial for creating a lean […]
Read MoreFlying long distances always includes changing airplanes midway. Naturally, that’s a hassle for everybody, especially if you need to wait a few hours between flights. Luckily, things might change for the better – Qantas just completed the longest flight, ever. The company claimed the record from Singapore Airlines, which held the record for a flight […]
Read MoreA lot of well-respected automotive and aircraft companies are already working on flying cars, bringing the long-awaited dream to reality. However, the first such product might be launched by a startup. The Munich-based company called Lilium already showed a video of a working air taxi prototype, which they want to launch in 2025. The Lilium […]
Read MoreYou’ve probably encountered the abbreviation NPS previously on our or similar websites. It means “Nominal Pipe Size,” and it is the North American standard for measuring pipe sizes used for various pressures and temperatures. The NPS standard is widely accepted in the USA, but some things have to be observed correctly in order to find […]
Read MoreApplying heat to metals can make them easier to forge, machine, weld, and fabricate. However, this also brings some issues with it, metals expand when heated, which makes the whole fabrication process more demanding. Luckily, every alloy comes with a predetermined coefficient of thermal expansion. This coefficient shows how much a given alloy will expand […]
Read MoreWe often mention that said metal is “easy to machine” or “difficult to machine” on our alloy pages, but what is machinability really? To answer that question, we need to first talk about machining and why it’s essential in almost every industry that uses alloys. Machining is the process of removal of raw material, in […]
Read MoreElectric planes flying on batteries are no longer a midsummer night’s dream, as an Israeli startup named “Eviation” is planning to introduce the first one by 2021 which will carry nine passengers over distances of up to 650 miles (1045 km). The key technological development that makes this possible is the existence of high-density dry […]
Read MoreDelivering packages with the help of drones is certainly not a novelty, but it is still not spread enough to replace conventional methods. Amazon wants to change that with their new hexagonal drone, which was presented at their re:MARS Conference. This drone should improve the Primer Air delivery program, which is available in selected countries […]
Read MoreIs there anything that is still secret in our digital world today? How secure is your everyday movements, day to day routines and most intimate information? Are we really protected by firewalls and passwords to secure our most precious information? Have we become so gullible to accept the big banners on software promotions promising just […]
Read MoreThe Dragon II capsule that carried out a non-piloted test flight to the ISS in March has exploded during a later test on the ground, as confirmed by the SpaceX vice president, Hans Koenigsmann. The explosive event was already apparent from a video that leaked late last month, but the level of the vessel’s destruction […]
