GKN Aerospace delivers first ICC to UltraFan engine demonstrator

Global company GKN Aerospace, a Tier 1 multi-technology aerospace supplier with facilities in 13 countries, delivered the first Intermediate Compressor Housing (ICC) to the Rolls-Royce UltraFan engine demonstrator program. The UltraFan, which is a next-generation family of engines, aims to deliver a 25% improvement in fuel efficiency over the automaker’s first generation Trent engines, and has a geared design and new engine core architecture. GKN Aerospace is a lead partner in Clean Sky 2 – Europe’s largest EU-funded aviation research program Horizon 2020 – as well as the UltraFan demonstrator program, and is responsible for the design and manufacture of the ICC, which is a structure located between the compressor housings that carry the gas loads from the rotor to the motor housing and the thrust mounts. In developing, manufacturing and testing the ICC, GKN has validated several new technologies, including a sectorized manufacturing concept with castings that uses a welding method based on computer simulation, 3D printing, aerodynamics and l ” optimized purge system acoustics, etc. The goal is to perform full engine ground tests in 2022, followed by actual flight tests.

“The delivery of the UltraFan ICC engine to Rolls-Royce is a real milestone. It reaffirms the success of the Clean Sky2 collaboration program and we are delighted to have implemented our latest sustainable technologies in the development of ICC, ”said Henrik Runnemalm, Vice President of the Global Technology Center at GKN Aerospace in Sweden . “We are extremely proud to be a partner of the Rolls-Royce team and to contribute to this fuel-efficient wind turbine of the future.”

Bastion Cycles presents a new 3D printed cockpit system

At the Handmade Bicycle Show Australia, custom bike builder Bastion Cycles unveiled their new integrated cockpit system, which features a one-piece bar stem and clean internally routed fork and was made from printed titanium and carbon fiber. In 3D. It consists of three main parts: the fork, with its crown and 3D printed titanium dropouts, carbon fiber dropouts and steerer tube; the bar shank, with a 3D printed titanium shank and drops with a one-piece carbon fiber crossbar; and the 3D printed titanium compression cap that is glued into the pivot, reducing the risk of damage from over-tightening. Bastion claims that the new cockpit system allows for increased ride quality and improved handling, and the aesthetics are also much cleaner, as the system can hide all the usual hoses and wiring.

“We’ve really tried to balance the addition of some aerodynamic advantages with the overall aesthetic and we’re extremely happy with the situation. We definitely believe it achieves this optimum condition of satisfying both form and function, ”said Bastion Engineering Director James Woolcock.

Through 3D printing, the company can customize the dimensions of the integrated cockpit system for each pilot to maximize aerodynamics, comfort and efficiency.

Tufts researchers turn silk into 3D printable leather

A small handbag shows the usefulness of silk leather in the manufacture of products

For many years, we humans have used leather to make all kinds of products, from shoes and handbags to vehicle interiors and saddles, due to its quality, reliability and durability. However, the only way this multibillion dollar industry can keep up with the demand is to process the hides of over 3.8 billion cows per year, which is not environmentally friendly at all – l The whole process leads to deforestation, greenhouse gas emissions, overuse of water and land and pollution of the environment. But researchers at Tufts University School of Engineering say they’ve developed a 3D-printable, recyclable, cheaper, leather-like material that actually comes from silk protein, a much greener alternative. The Silklab research team, which published a study on their work, only needs to use chemicals that are mild at room temperature to convert the silk fibers into a firmer, but still flexible, leather-like material. , which can be 3D printed in different textures and patterns.

“Our work centers on the use of naturally occurring materials that minimize the use of toxic chemicals while maintaining material performance to provide alternatives to products commonly and widely used today. By using silk, as well as cellulose from textile and agricultural waste and chitosan from shellfish waste, and all the relatively mild chemistries used to combine them, we are moving towards this goal ”, said Fiorenzo Omenetto, Professor Frank C Doble of Engineering at the Tufts School of Engineering, director of the Tufts Silklab and corresponding author of the study.

3D printing combines Apple TV remote control with AirTag

So on the one hand, Apple has the Siri remote, which is super unpopular because it gets lost very easily due to its quality. On the other hand, Apple has also released something called AirTag trackers, which use ultra-broadband local tracking and a Bluetooth network of other Apple devices to help you find your missing Apple items no matter how far away they are. to a small speaker and UWB chip. But when Apple redesigned the Siri Remote, it didn’t include this chip so that the remote could be tracked by other iPhone devices when it inevitably gets lost in the cushions of your couch, and that seems like a missed opportunity. ridiculous, especially since the company produces cases. for most of its other products. Thank goodness for the makers, who are busy creating 3D printed models – available on Thingiverse, Etsy, and eBay for newbies – for Siri Remote cases that can hold both the remote and an AirTag tracker.

“To be clear, this is the weakest workaround for the fact that Apple didn’t just put a UWB chip and a little speaker in its $ 60 remote. It can’t be an expensive thing: AirTags have one and they only cost $ 30. Roku has put tiny speakers in his remotes to make them easier to find for years. There was even a strange message in Siri that seemed to indicate the possibility of finding a lost Siri remote using the virtual assistant – but Apple deleted the message a few hours later, ”

“As such, I cannot explain why Apple refused to take this mind-boggling and obvious path. But I wonder why Apple doesn’t come up with a nicer version of this exact 3D printed concept (ideally from nicer, more durable materials that actually match the rest of the material and would be nicer to use on a daily basis). “
