Model Airplanes

(MENAFN – The Conversation) The Fabrication City concept puts manufacturing back in the hands of communities — using 3D printers. It could have far-reaching implications for economic development, environmental sustainability, inclusion and other benefits. The use of 3D printing provides cities with opportunities through their local innovators and entrepreneurs.

The process of 3D printing layers materials to create three-dimensional objects using digital equipment. Local makers are given access to fabrication labs equipped with technology to learn and this incubation environment can develop future entrepreneurs.

3D printers can now print using a variety of materials, including metal, revolutionizing manufacturing processes. Shutterstock

The fabrication city model emerged around 2011, developed by the MIT’s Centre for Bits and Atoms and by over 1,000 Maker Centres that give local makers access to 3D printing and other production tools. There are also neighbourhoods and city clusters that facilitate the maker movement .

There are opportunities for individuals and groups to create and market products from used or new materials using a digital device and additive technology . By facilitating these activities, cities can radically transform the way production and consumption happens within their region. Interconnecting people and processes to create local and regional inclusive innovation and economic growth while also reducing environmental impacts. What might we re-use if we practice more inclusive innovation and how might we change the local economy if we support local sourcing?

With Energizer grabbing headlines with its 18,000mAh smartphone, the company is back for more with the foldable Power Max P8100S.

Quietly announced during MWC 2019, the Power Max P8100S features two displays — a 6-inch display with Full HD+ resolution on the outside and an 8.1-inch display with Full HD+ resolution on the inside. The phone is unlike the Huawei Mate X, which features one 8-inch display that turns into two smaller displays when folded.

We didn’t get a chance to use any of the displays on the Power Max P8100S, since the phone was in a glass case. According to Energizer, Samsung and Huawei have priority at the production factories where these displays are made. As a result, Energizer was unable to get all the parts for the model shown off in Barcelona.

Even so, this might be the ugliest hinge design for a foldable smartphone we’ve seen so far. The hinge’s design reminds me of the part of the jetway that looks like an accordion and extends to the airplane. The design is likely cost-effective for Energizer, but it also has us a bit concerned about how well it’ll hold up over time.

At least the rest of the Power Max P8100S reads off like a proper 2019 flagship smartphone. The phone features dual rear 48- and 12-megapixel cameras, a 24MP selfie camera, the Qualcomm Snapdragon 855 processor, 8GB of RAM, 256GB of expandable storage, and a

he China-developed MA700 turboprop aircraft has entered the trial-manufacturing and test phase, announced the state-owned Aviation Industry Corporation of China (AVIC) Friday.

The first MA700 is expected to roll off the production line this September.

The MA700 is the third member of China’s “Morden Ark(MA)” regional airplane family following the MA60 and MA600. The AVIC is striving to conduct the maiden flight by the end of 2019, said AVIC.

It is developed by the AVIC XAC Commercial Aircraft (AVIC XACC) in Xi’an, in northwest China’s Shaanxi Province.

By the end of 2018, the company started the major parts assembly work of the plane’s nose, forebody and cargo, and its wings are already in parts assembly.

The MA700 turboprop is designed with a maximum speed of 637 km per hour and a single-engine ceiling of 5,400 meters.

The model is adaptive to airports with high temperatures, high altitudes and short runway conditions. It is capable of operating in complex air route conditions.

To date, it has received 285 intended orders from 11 customers at home and abroad.

Bats have inspired the design of flying vehicles for more than a century. Now, new computer modeling of bats wings and their flight patterns will help inspire the next generation of wing design.

Researchers from the University of British Columbia and the National University of Singapore have developed a comprehensive 3D computer model of bat wing-flapping flight that might help drone and airplane designers create more nimble vehicles. 

The model gives never-before-seen insight into the flight flapping mechanisms of batwings. This information might be the key to a new era of aviation design. The high-fidelity model is scalable and has the potential to be used by designers and engineers alike.

Bats wings flex and adapt to air conditions

“Bats can navigate tight spaces and negotiate gusts of wind with apparent ease,” says Rajeev Jaiman, the senior author of the study and a professor of mechanical engineering at UBC.

“By understanding how they do what they do, we may be able to design flying devices that operate more effectively than before, including in emergency and military situations.” 

Flapping wings designs have proven difficult for humans to master, however they hold many advantages of fixed-wing flight. Flapping wings are quieter and provide greater maneuverability but have proven to be difficult to translate to human-scaled machines.
