Nanotechnology enables engineers to weld previously un-weldable 7075 aluminum alloy



press release



Super-strong but lightweight, AA 7075 now could be more widely used in automobiles and other manufacturing thanks to UCLA research

An aluminum alloy developed in the 1940s has long held promise for use in automobile manufacturing, except for one key obstacle. Although it’s nearly as strong as steel and just one-third the weight, it is almost impossible to weld together using the technique commonly used to assemble body panels or engine parts.

That’s because when the alloy is heated during welding, its molecular structure creates an uneven flow of its constituent elements — aluminum, zinc, magnesium and copper — which results in cracks along the weld.

Now, engineers at the UCLA Samueli School of Engineering have developed a way to weld the alloy, known as AA 7075. The solution: infusing titanium carbide nanoparticles — particles so small that they’re measured in units equal to one billionth of a meter — into AA 7075 welding wires, which are used as the filler material between the pieces being joined. A paper describing the advance was published in Nature Communications.




Using the new approach, the researchers produced welded joints with a tensile strength up to 392 megapascals. (By comparison, an aluminum alloy known as AA 6061 that is widely used in aircraft and automobile parts, has a tensile strength of 186 megapascals in welded joints.) And according to the study, post-welding heat treatments, could further increase the strength of AA 7075 joints, up to 551 megapascals, which is comparable to steel.

Because it’s strong but light, AA 7075 can help increase a vehicle’s fuel and battery efficiency, so it’s already often used to form airplane fuselages and wings, where the material is generally joined by bolts or rivets rather than welded. The alloy also has been used for products that don’t require joining, such as smartphone frames and rock-climbing carabiners.

But the alloy’s resistance to welding, specifically, to the type of welding used in automobile manufacturing, has prevented it from being widely adopted.



“The new technique is just a simple twist, but it could allow widespread use of this high-strength aluminum alloy in mass-produced products like cars or bicycles, where parts are often assembled together,” said Xiaochun Li, UCLA’s Raytheon Professor of Manufacturing and the study’s principal investigator. “Companies could use the same processes and equipment they already have to incorporate this super-strong aluminum alloy into their manufacturing processes, and their products could be lighter and more energy efficient, while still retaining their strength.”



The researchers already are working with a bicycle manufacturer on prototype bike frames that would use the alloy; and the new study suggests that nanoparticle-infused filler wires could also make it easier to join other hard-to-weld metals and metal alloys.

The study’s lead author is UCLA graduate student Maximilian Sokoluk. The other authors are Chezheng Cao, who earned a doctoral degree from UCLA in December, and Shuaihang Pan, a current UCLA graduate student. Li holds faculty appointments in mechanical and aerospace engineering, and in materials science and engineering.

Nanoparticle-enabled phase control for arc welding of unweldable aluminum alloy 7075
Abstract


Lightweight materials are of paramount importance to reduce energy consumption and emissions in today’s society. For materials to qualify for widespread use in lightweight structural assembly, they must be weldable or joinable, which has been a long-standing issue for high strength aluminum alloys, such as 7075 (AA7075) due to their hot crack susceptibility during fusion welding. Here, we show that AA7075 can be safely arc welded without hot cracks by introducing nanoparticle-enabled phase control during welding. Joints welded with an AA7075 filler rod containing TiC nanoparticles not only exhibit fine globular grains and a modified secondary phase, both which intrinsically eliminate the materials hot crack susceptibility, but moreover show exceptional tensile strength in both as-welded and post-weld heat-treated conditions. This rather simple twist to the filler material of a fusion weld could be generally applied to a wide range of hot crack susceptible materials.

Nosedives would make for better landings on weighty Mars missions

press release




The heaviest vehicle to successfully land on Mars is the Curiosity Rover at 1 metric ton, about 2,200 pounds. Sending more ambitious robotic missions to the surface of Mars, and eventually humans, will require landed payload masses in the 5- to 20-ton range. To do that, we need to figure out how to land more mass. That was the goal of a recent study.

Normally, when a vehicle enters the Mars atmosphere at hypersonic speeds of about Mach 30, it slows down quickly, deploys a parachute to slow down more then uses rocket engines or air bags to finish the landing.

“Unfortunately, parachute systems do not scale well with increasing vehicle mass. The new idea is to eliminate the parachute and use larger rocket engines for descent,” said Zach Putnam, assistant professor in the Department of Aerospace Engineering at the University of Illinois at Urbana-Champaign.

According to Putnam, when the lander has slowed to about Mach 3, the retropropulsion engines are ignited, fired in the opposite direction to slow the vehicle down for a safe landing. The trouble is, that burns a lot of propellant. Propellant adds to vehicle mass, which can quickly drive up vehicle cost and exceed the current launch capability here on Earth. And every kilogram of propellant is a kilogram that can’t be payload: humans, science instruments, cargo, etc.

“When a vehicle is flying hypersonically, before the rocket engines are fired, some lift is generated and we can use that lift for steering,” Putnam said. “If we move the center of gravity so that it’s not uniformly packaged, but heavier on one side, it will fly at a different angle.”

Putnam explained that the flow around the vehicle is different on the top and the bottom which creates an imbalance, a pressure differential. Because the lift is in one direction, it can be used to steer the vehicle as it decelerates through the atmosphere.

“We have a certain amount of control authority during entry, descent, and landing—that is, the ability to steer.” Putnam said. “Hypersonically, the vehicle can use lift to steer. Once the descent engines are ignited, the engines have a certain amount of propellant. You can fire engines in such a way that you land very accurately, you can forget about accuracy and use it all to land the largest spacecraft possible, or you can find a balance in between.

“The question is, if we know we’re going to light the descent engines at, say, Mach 3, how should we steer the vehicle aerodynamically in the hypersonic regime so that we use the minimum amount of propellant and maximize the mass of the payload that we can land?

“To maximize the amount of mass we can landing on the surface, the altitude at which you ignite your descent engines is important, but also the angle your velocity vector makes with the horizon—how steep you’re coming in,” Putnam said.

The study clarified how to make the best use of the lift vector, using optimal control techniques to identify control strategies that can be used hypersonically across different interplanetary delivery conditions, vehicle properties, and landed altitudes to maximize landed mass.

“Turns out, it is propellant-optimal to enter the atmosphere with the lift vector pointed down so the vehicle is diving. Then at just the right moment based on time or velocity, switch to lift up, so the vehicle pulls out and flies along at low altitude,” Putnam said. “This enables the vehicle to spend more time flying low where the atmospheric density is higher. This increases the drag, reducing the amount of energy that must be removed by the descent engines.”

The study, “Entry Trajectory Options for High Ballistic Coefficient Vehicles at Mars,” was authored by Christopher G. Lorenz and Zachary R. Putnam. It appears in the Journal of Spacecraft and Rockets.

The research was funded by the NASA Jet Propulsion Laboratory.


Entry Trajectory Options for High Ballistic Coefficient Vehicles at Mars
Abstract
Future large-scale Mars surface exploration missions require landed masses beyond the capability of current entry, descent, and landing technology. Hypersonic trajectory options for large ballistic coefficient vehicles are explored to assess the potential for improved landed mass capability in the absence of landed accuracy requirements. Hypersonic trajectories appropriate for use with supersonic parachute and supersonic retropropulsion descent systems are studied. Optimal control techniques are used to determine hypersonic bank-angle control profiles that achieve favorable conditions at terminal descent initiation. Terminal descent initiation altitude-maximizing bank strategies for parachute descent systems are explored across vehicle and mission design parameters of interest. A tradeoff between altitude and flight-path angle at terminal descent initiation is identified. Hypersonic trajectories that minimize required propellant for propulsive descent are identified and studied parametrically. A hypersonic ballistic coefficient and lift-to-drag ratio are shown to have the largest effects on required propellant mass fraction; changes to the vehicle state at entry interface have a smaller effect. The space of reachable supersonic retropropulsion ignition states is presented over a range of vehicle and trajectory parameters. Overall, results indicate execution of an appropriate hypersonic bank profile can significantly increase the parachute deploy altitude for parachute descent systems or reduce the amount of propellant required when compared to full lift-up entry for supersonic retropropulsion descent systems operating at Mars.

Airbus and Hisdesat successfully processed the first TerraSAR-X / PAZ Radar Interferogram



press release




Friedrichshafen, Madrid, 11 February 2019 – Airbus Defence and Space and Hisdesat Servicios Estratégicos, S.A. have generated the first joint TerraSAR-X / PAZ Radar Interferogram. This milestone demonstrates the missions’ capacity for cross-sensor interferometry, whose processing is among the most challenging.



Interferograms are typically used to derive the topographic elevation and deformation of the Earth’s surface, and are created using at least two different images acquired at different date. This flattened Cross-Sensor-Interferogram has been created from a mixed image pair with 4 days temporal separation acquired by TerraSAR-X and PAZ (StripMap scenes from 22 and 26 November 2018). The area covers the oil and gas production site Burgan (Kuwait) and parts of the Persian Gulf. The oil field is the world largest sandstone oil field with the total surface area of about 1,000 km².



As PAZ is positioned in the same orbit as TerraSAR-X and TanDEM-X and features exactly identical ground swaths and acquisition modes, they all three form a high-resolution SAR satellite constellation, jointly exploited by Hisdesat and Airbus. With the launch of PAZ, the observation repeat cycle has been divided by half, which improves the monitoring of fast ground deformation phenomena that can endanger lives and infrastructures.



“This is a major step towards achieving the implementation of our TerraSAR-X / PAZ Radar Constellation. The level of accuracy obtained with this interferogram is a guarantee for our customers to continue to rely on the high quality standard we have set with TerraSAR-X and TanDEM-X, but with an improved monitoring capacitiy” said Hanjo Kahabka, Head of Production and Radar Constellation Manager at Airbus Defence and Space, Intelligence.



“In Hisdesat we are very proud of reaching this milestone. Interferometry is one of the most technically demanding applications and thanks to this successful joint exercise with Airbus we have not only demonstrated the top performance of our PAZ satellite but its full compatibility with TerraSAR-X and TanDEM-X. Now operation in constellation can become a reality and we will be able to provide to our customers full set of images and services with the constellation.” said Miguel García Primo, Chief Operating Officer at Hisdesat.

Airbus invests €25 million in the future of its aerospace site in Ottobrunn/Taufkirchen, near Munich



press release




Ottobrunn/Taufkirchen, 11 February 2019 – Airbus is expanding its aerospace activities at its site in Ottobrunn/Taufkirchen, near Munich. Today, it has reached two new milestones, with Bavarian Minister-President Markus Söder and Dirk Hoke, CEO of Airbus Defence and Space, giving the green light for the modernisation of solar array production for satellites, and for the commissioning of expanded clean rooms for optical satellite instruments. In total, the company will be investing approximately €25 million.



In February 2019, Airbus will begin building an Industry 4.0 factory to automate and digitalise the production of solar arrays for satellites. This will entail a complete revamp of the production building, during which it will be expanded by 800 m2 to a total of 5,500 m2. A robotic assembly line will also be introduced. This €15 million investment demonstrates the company’s ability to remain competitive on the world market, while the automated assembly line will allow throughput times and costs to be halved. This state-of-the-art technology will safeguard 170 jobs and position the company to maximise future growth opportunities such as satellite constellations or ‘New Space’ approaches. Furthermore, ongoing cutting-edge research will be supported, particularly in the area of scientific satellites, such as the Jupiter mission or missions to the Sun or Mercury.



In addition Airbus will use the clean room (expanded by 250 m2 to a total of 1,700 m2) for the integration of satellite-based optical instruments, an area in which Airbus has invested over €10 million at its Ottobrunn/Taufkirchen site. The new clean room will be used by some of the 150 employees in the Optical Instruments business unit to build the MERLIN instrument (Methane Remote Sensing Lidar Mission). MERLIN is a Franco-German satellite project to measure the methane concentration in Earth’s atmosphere to improve understanding of climate change.



“The aerospace site in Ottobrunn/Taufkirchen has not only shaped the history of cutting-edge technology over the last 60 years, it is also actively shaping the future. Today, our solar array production marks our entry into the age of Industry 4.0, with the site now boasting the largest clean room for optical satellite integration in Germany. This will improve our competitive standing worldwide and will contribute towards safeguarding local jobs,” said Dirk Hoke, CEO of Airbus Defence and Space.
