A little more than three years after separating from Alcoa Inc., engineered metal products company Arconic Inc. is splitting again. On April 1, 2020, the company’s Engineered Products and Forgings business (jet engine components, aircraft fastening systems, engineered structures, and forged wheels) become Howmet Aerospace Inc. The Global Rolled Products business (sheet, plate, rolled aluminum, extrusions, and building/construction systems) will be spun off as Arconic Corp.
John C. Plant, Arconic Inc.’s CEO since February 2019, and Tolga Oal will lead Howmet Aerospace as co-CEOs. Plant and Oal previously held positions at TRW Automotive; Plant for 12 years as CEO and Oal with finance and operations.
Timothy D. Myers, Arconic Inc.’s Global Rolled Products executive vice president and group president will become Arconic Corp. CEO. Myers has nearly 30 years’ experience with Arconic Inc. and its predecessors.
Howmet Aerospace takes its name from Howmet Castings, a company Alcoa bought in 2000. It will retain aerospace airfoils and ring production facilities in Whitehall, Michigan; Morristown, New Jersey; and Rancho Cucamonga, California. Howmet Aerospace will continue as sole-source of titanium and aluminum bulkheads for the F-35 Joint Strike Fighter.
Arconic Corp. will keep the Davenport, Iowa, production assets: a 4,200-ton thick-plate stretcher for aluminum and aluminum-lithium plate, horizontal heat-treat furnace, and aluminum-lithium cast house. It also retains the aluminum sheet, cast plate, extrusions, forgings, and large horizontal press capabilities at Samara, Russia.
The leading provider of aerospace sheet, Arconic produces all of Boeing’s aluminum wing and fuselage skins. It also is sole supplier to Airbus for some wing, fuselage, and structural components and provides aluminum sheet and plate for every Airbus airplane.

Record-setting 1MW ring motor
Departments - 1 Last Look
Electric motor demonstrator sets two world records in two hours.
1MW ring motor produces torque and power without using permanent magnets.
Electric motors powerful enough to propel aircraft the size of a Boeing 737 as part of a hybrid propulsion system could revolutionize aviation fuel economy. NASA recently awarded grants to a group making motors 5x lighter and more efficient than any in production.
Dr. Codrin-Gruie (CG) Cantemir, a research scientist at The Ohio State University’s Center for Automotive Research, was awarded the grant for his 10MW Ring Motor concept that includes a tuned coil and variable-cross-section windings married to technology that achieves direct contact between coils and coolant. This enables stator magnetic field production at high frequencies while minimizing specific high frequency losses in solid conductors. The motor is an induction machine in reverse (an out-runner) where the field generated by the internal stator induces currents in a squirrel cage located in the rotor. This interaction produces torque and power without needing permanent magnets (PMs). NASA encouraged Cantemir to explore using induction motors rather than PM systems because they are safer and more robust.
In a preliminary test of a validation 1MW induction motor, Ohio State, in partnership with NASA, set two world records: one for absolute normalized continuous power density and the other for continuous power density for an induction motor.
The previous record for normalized continuous power density was set by Siemens of Germany at approximately 2.05W/kg*rpm and used rare-Earth neodymium magnets and expensive cobalt-based magnetic material. The 2.60W/kg*rpm record uses only off-the-shelf magnetic materials without PMs.
One unexpected reason for the record is the use of aluminum rather than copper as the conductor in the stator coils. Theoretical work conducted with the grant showed researchers that in certain situations, aluminum will behave better than copper.
“It may be counterintuitive, but a power-dense motor uses less material and less tooling versus conventional, hence the cost saving,” Cantemir says.
A 2.7MW motor is being developed to further validate the concept’s performance.

Growing the space economy
Features - Cover Story
NASA’s efforts to commercialize space exploration are encouraging businesses to invest in new technologies and capabilities.

The Apollo program remains one of the great technological accomplishments of humankind, but it didn’t accelerate space commerce the way its visionary leaders intended. We haven’t been back to the moon since 1972. We don’t have a human settlement on Mars. We don’t have an American spacecraft to take our astronauts to and from space. One could be disappointed, but things are changing rapidly.
Energizing many are the thrilling successes of SpaceX and other privately funded ventures, and private markets are now paying attention to lower-cost missions enabled by small satellites. This is shining a light on current space capabilities and NASA is taking advantage of this newfound attention.
Accelerating space commerce
Half a century after Apollo, NASA is taking a different approach to accelerate space commerce, exploration, and discovery. Rather than traditional cost-plus contracts, NASA is acting more like a customer buying a service. By using its existing Other Transaction Authority – typically Space Act Agreements or other Public-Private Partnerships – NASA is providing seed funding and asking industry to invest in an off-world future. With industry sharing risk, we expect to have commercial sources for every leg of the transportation network from Earth to the moon by the late 2020s.
This fundamental shift could unleash a wave of new commercial capabilities, from in-space housing to taxis ferrying people and cargo to and from the moon and Mars. Manufacturers would be incentivized to move boldly if they know NASA and other government customers will buy the services they enable.
Tested approach
Government has done this in the past. The Air Mail Act of 1925 allowed the Postmaster General to contract with private companies to deliver mail. Companies that received the 12 contracts are credited with ultimately creating the modern airline industry. To establish an off-world future, we want multiple suppliers for each leg of the transportation network so there’s assured access and competition to drive costs down. We are headed in that direction.
Starting in 2006, NASA’s Commercial Orbital Transportation Services (COTS), and its follow-on Commercial Resupply Services (CRS and CRS2) contracts, developed the cargo delivery services that support the International Space Station (ISS). COTS funded the development of the SpaceX Dragon and Northrop Grumman Cygnus systems. CRS and CRS2 were awarded in 2008 and 2015 for delivery services, adding Sierra Nevada’s Dream Chaser as a third service supplier. Compared to NASA’s traditional procurement approach, these contracts gave industry broad leeway in how to design systems, only controlling those parts that interacted with the ISS. To date, 29 cargo delivery flights to the ISS have been made under this program.
The Commercial Crew program is poised to deliver astronauts to space in 2020 on U.S.-made spacecraft for the first time since 2011. Boeing’s CST-100 Starliner and SpaceX’s Dragon are being prepared for their first missions. While developed under a more traditional procurement framework, the result is still a commercial product, giving government astronauts and private citizens the choice of flying on two different vehicles to and from space.
Building infrastructure
We have long envisioned a future where more people are living and working in space. They will conduct scientific research, manufacture goods for use in space or back on Earth, and occupy new platforms for adventure tourism. This time, we are going to the moon to stay, so we will need a range of support services, both human and robotic, and new infrastructure to support long-term settlement.
Artemis program:
NASA is managing and soliciting a broad network of partners for transportation services from the Earth to the moon. Several different procurements are active, with each using a slightly modified version of the approach used to procure ISS cargo delivery services.
Commercial Lunar Payload Services (CLPS) program: Valued at $2.6 billion throughout 10 years, CLPS will deliver small- and medium-sized payloads to the lunar surface. Nine companies were announced in November 2018, with five companies added a year later. These 14 companies offer a catalog of options, with each able to bid on NASA-issued task orders. CLPS is moving fast, with lunar landing task orders already awarded to Astrobotic and Intuitive Machines. These missions will carry small payloads to the lunar surface in 2021. NASA intends to fly up to two CLPS missions per year.
Lunar Gateway: Currently in development, this small, human-tended space station will orbit the moon. The Orion spacecraft, launched on the Space Launch System (SLS), will bring astronauts to Gateway, the staging point for robotic and crewed exploration of the lunar surface. A future version of Gateway is envisioned as the staging point for NASA’s Deep Space Transport concept to travel to Mars. The Lunar Gateway will include the Power and Propulsion Element (PPE) developed by Maxar, and the Habitat and Logistics Outpost (HALO) module developed by Northrop Grumman. Contracts for these two elements were awarded in 2019.
Gateway Logistics vehicles: A new fleet will deliver payloads and other cargo to support missions to the lunar surface. Proposals were delivered in October 2019, and NASA is expected to award up to $7 billion in contracts, funding development and services throughout 15 years. These vehicles will deliver at least 3,400kg of pressurized cargo and 1,000kg of unpressurized cargo to the Gateway on each mission.
Human Landing System (HLS): A key element of Artemis will be transporting astronauts from the Gateway to the lunar surface. NASA plans to award contracts to two different teams to participate in the first phase of this multiyear effort. If this multiple-source approach continues through development, these landers will be available to support government and commercial missions to the moon in the mid-to-late 2020s.
NASA is working with partners to design and develop a small spaceship called the Gateway that will orbit the moon.
Beyond the moon
Separately from Artemis, NASA is preparing to invest in the low Earth orbit (LEO) commercial ecosystem to develop commercial modules and free flyers. Combined with existing commercial launch companies such as SpaceX, ULA, Northrop Grumman, and RocketLab, there is growth potential in LEO space development.
Finally, we will need infrastructure in space to support our off-world future. The development of power; communications; positioning, navigation, and timing (PNT); habitation and manufacturing platforms; and civil infrastructure – roads and launch/landing pads – is essential. The leadership and foresight that led to the Transcontinental Railroad, the Interstate Highway System, and the Global Positioning System (GPS) will be needed to spur future commercial development in space.
These examples are incredibly capital intensive, so how does the current industrial base adjust and grow to support future growth in space?
After years of consolidation, the space industry is seeking new suppliers with commercial operations experience. NASA’s investments could create market surety, encouraging businesses to invest in new space technologies and applications. Solving the challenges of living and working in space – protecting humans from radiation, protecting components from lunar dust – requires the ingenuity of many.
Planetary exploration requires broader capabilities and knowledge than what’s available today. We’ll need expertise in telecommunications, agriculture, mining, and construction to build an off-world future. But these markets will take time to develop, so how will we encourage these non-endemic industries to come and invest for the longer term required in the space industry?
Great economic benefit comes from exploration. It has been governments’ responsibility to invest in the infrastructure needed to move the economy forward. NASA’s investments in transportation are laying the groundwork for a much larger space economy. This foundation, combined with the commercial launch services available and in development, has the potential to change how we live on Earth.

Decreasing IIoT design time
Features - Design & Automation
With the right tools, developers can construct a software platform that adds greater levels of automation, machine vision, and connectivity to smart factories.
Discussions about industry today often focus on the substantial potential of the Industrial Internet of Things (IIoT). It promises significant productivity gains, operational efficiency, and bottom line revenue increases, but only with a supply chain offering reliability, stability, and longevity. These values will become more important as manufacturers and system integrators adopt more automation, connectivity, and autonomy – with faster design cycles and more competition increasing the pressure to get to market quickly. The interplay between these requirements will define the industrial marketplace and innovation that developers contribute to it.
Robotic arm used in factory automation for manufacturing.
Connectivity, reliability
Industry 4.0 reveals how IIoT can upgrade the factory floor. With the right functionality, it can make any industrial environment smarter, using connectivity to collect sensor information that turns yesterday’s Big Data into today’s insights.
Industry’s need for efficiency is acute, so connectivity and efficiency are crucial for developers and organizations to consider throughout the design process.
Supply and price stability ensures manufacturers can continue to develop, build, deliver, and maintain their systems for extended periods. This often requires component suppliers to guarantee supply continuity for as long as 15 years, with a commensurate price guarantee for up to 4 years.
Assess technologies for applications
To balance connectivity, efficiency, and reliability, developers must select suitable technology for each application.
Tracking data from an Industrial IoT application in a factory.
Consider ON Semiconductor’s intelligent power module (IPM) family, which uses insulated metal substrate technology (IMST). This technology integrates many active components on a metal substrate for high integration with excellent thermal conductivity.
From IPMs, motor drivers (brushless DC motor, stepper, brushed), load drivers and relay drivers – vast amounts of semiconductor technology – is in industrial robots and other IIoT applications. These are supported by a growing number of optimized metal-oxide semiconductor field-effect transistor (MOSFET) and insulated-gate bipolar transistor (IGBT) drivers, and high-performance optocouplers that enable engineers to develop reliable industrial drive systems that deliver accurate control in applications using any combination of low-voltage motors and high-current loads.
For efficiency and reliability, temperature, motion, ambient light, and image sensors for machine vision must be optimized for electrically noisy conditions. The sensors’ small signals then need to be filtered and amplified before being converted to digital data and passed to a central processor. Coupled with this is circuit protection from electrostatic discharge (ESD) protection diodes.
The control element of industrial automation typically involves power semiconductors manufactured using MOSFETs or IGBTs, and silicon carbide (SiC) transistors. Switching and power semiconductor manufacturers now offer devices that meet power inverter circuits and motor driver requirements. Compliance with international standards is mandatory in several industries, so many manufacturers develop parts that adhere to international quality standards including ISO 90001:2015 and IATF 16949:2016.
Speeding time to market with IIoT
The seemingly opposing demands of developing more complex circuits within smaller time windows and often lower budgets is prolific in IIoT, putting pressure on development teams to bring machinery invented before the Internet age to the cutting edge of future technology.
For engineers to develop and optimize new products, it is essential to give them the tools they need to make that process as simple as possible.
For design teams, interactive block diagrams present engineers with a reference design for specific applications. Each diagram presents a selection of potential solutions for each key functional block in design. Further details for each component can be accessed from the block diagram and added to a custom worksheet to quickly develop design ideas.
When moving to the early evaluation plan, developers can now turn to ON Semiconductor’s Strata Developer Studio cloud-connected platform as a starting point. Software automatically recognizes evaluation boards once connected to a host PC, then retrieves the latest design collateral and auto-configures the evaluation board, letting engineers get up and running quickly. Paired with Avnet’s global expertise, those designs can go from ideas on a napkin to a product ready with design for manufacturability, strong supply chain, and regulatory considerations.
Bring in partners
IIoT will encompass a wide range of technologies, from sensors to the cloud. Robotics and automation are safety-critical applications demanding the best solutions and developers need partners who can provide the parts and the services to move from idea to product and product to market. Avnet and ON Semiconductor have created a product development ecosystem and software platform to shorten design time for developers and speed time to market.
