New Supercomputer Simulations Could Help Electric Spacecraft Propulsion Take a Leap

SPACE reports, “Spacecraft powered by electric propulsion could soon be better protected against their own exhaust, thanks to new supercomputer simulations. Electric propulsion is a more efficient alternative to traditional chemical rockets, and it’s being increasingly used on space missions, starting off with prototypes on NASA’s Deep Space 1 and the European Space Agency’s SMART-1 in 1998 and 2003, respectively, and subsequently finding use on flagship science missions such as NASA’s Dawn and Psyche missions to the asteroid belt. There are even plans to use electric propulsion on NASA’s Lunar Gateway space station.”

Aviation Week Article: Pratt & Whitney Unveils Details Of Hydrogen-Steam Hybrid Engine Cycle

Guy Norris at Aviation Week reports, “Hydrogen fuel may offer attractive pathways toward the goal of zero carbon emissions, but turning that vision into a practical propulsion system is another matter. Now Pratt & Whitney thinks it may have taken the first steps along that path with the Hydrogen Steam-Injected, Intercooled Turbine Engine (HySIITE) concept—a novel hybrid engine configuration that combines the advantages of the fuel’s cryogenic properties with the thermodynamic benefits of steam injection. Pratt & Whitney has unveiled details of the concept, which has been studied under a two-year $3.8 million U.S. Energy Department Advanced Research Projects Agency–Energy (ARPA-E) effort. While Pratt acknowledges the cycle is complex and requires more study, it is encouraged by the results, which show potential for as much as 35% lower energy use compared with current state-of-the-art engines.”

Dryden Lecturer Addresses Future of Getting to Greener Aviation

By Anne Wainscott-Sargent, AIAA Communications Team

As the aviation sector looks to achieve net zero carbon emissions by 2050, the biggest gains may not happen in the air but on the ground, stated Tim Lieuwen, the 2025 AIAA Dryden Lecturer in Research, during the 2025 AIAA SciTech Forum in January.

“The least cost way to get to a net-zero society is to take a system view about economy-wide CO2 emissions and where and how aviation fits into that, rather than trying to zero out CO2 emissions sector by sector.  It makes sense if you think about it – it’s a whole lot cheaper to manage your CO2 emissions from something that’s sitting on the ground, potentially sitting right above a depleted oil reservoir versus trying to manage something that’s flying around and has to deal with all the safety issues of aviation,” said Lieuwen.

The Georgia Tech executive vice president for Research, Regents’ Professor, holder of the David S. Lewis, Jr. Chair, and the executive director of the Strategic Energy Institute  explored the interconnectedness of energy sources, carriers, and storage systems, noting the significant role of fossil fuels in the current U.S. energy system and the potential for synthetic fuels.

He highlighted four different options for zeroing out climate impacts using a high-fidelity model of the entire energy system. Organized in a 2×2 matrix, the model showed the option of economy-wide decarbonization, where different sectors contribute in a coordinated way. Then he presented a visual of sector-by-sector decarbonization, where each sector individually zeroes out its contributions.

According to the EPA, transportation is the largest contributor of CO2 emissions, with the aviation sector contributing roughly 2.5%, compared with 28% from automobiles.

Lieuwen noted there is a difference between zero CO2 and net zero. Net zero focuses on the overall CO2 emissions budget, allowing for some sectors to potentially emit CO2 and some sectors to be net-negative CO2.  In this scenario, the least-cost role of aviation in an economy wide net-zero CO2 society is a mix of conventional fossil fuels and renewable hydrocarbons like sustainable aviation fuels (SAF). If aviation’s aim is to pursue “a least-cost societal net-zero target,” then he advocated for an economy-wide net zero strategy.

Using a least-cost model, the energy expert showed some surprising insights where fossil fuels and renewable fuels are equally split 50/50.

“Half are fossil fuels and the other half are synthetic fuels that you can manufacture like SAF. You see big growth in renewables and big growth in biofuels,” he explained.

Lieuwen also observed that in this least-cost world, half of all energy will rely on electricity which will prompt big growth in electrification, going from 20% to 50%. He also predicted significant R&D investments around power electronics, high-voltage motors, batteries, and energy storage.

Fossil Fuels Dominate Current Energy Economy
Another big takeaway was how society moves and stores energy will continue to use  fossil fuels, although in a significantly diminished role from today.

“We’re in an 80/20 split with the current U.S. energy economy as a whole, which means that we use fossil fuels roughly for 80% of the means by which we move energy around and store it. We use electricity as an energy carrier for the other 20%. These are multi-trillion-dollar sectors. It’s important to recognize the interconnectedness of all this. For example, the aviation sector is leveraging and contributing technologically to and is also benefiting from infrastructure of existing industrial sectors, such as oil pipelines and the oil refining industry.”

Aviation’s Critical Role
Part of achieving this least-cost societal net-zero target in aviation is developing SAF, which currently are more expensive than fossil fuel, and will likely require policy levers, carbon taxes, or tax credits to become a reality, Lieuwen predicted.

There will continue to be a premium placed on aviation advances that offer thermal efficiency as well as operational flexibility.

“The ability to have systems that are low emission/high efficiency, but yet don’t surge/don’t stall, where your flame stays attached, where the system is stable, is very, very important,” said the researcher before briefly sharing highlights of his research that focuses on better understanding the interaction of how fast waves of flames move in combustion engines.

“The interaction of acoustic waves… create interference patterns which are controlled by how fast vortices move versus how fast waves on flames move,” he explained. “If a vortex is not moving at the same speed, what’s happening is you have two periodical disturbances moving at different velocities.”

This phenomenon leads to destructive instabilities in rockets, in home heaters, and in aircraft engines, Lieuwen shared.

Asked after his presentation if he thought the increased tempo in rocket launches would hurt efforts to decarbonize, Lieuwen said, “I would suspect the overall carbon footprint that is going to those direct launches will pale relative to other sectors.” He predicted major follow-on secondary impacts from all the satellite activity, however.

Nuclear’s Potential
Another question concerned the role of nuclear energy in getting to net zero. “Nuclear is really important,” said Lieuwen. “In fact, if we could solve this problem of low-cost nuclear [energy] it would totally transform what least-cost net zero looks like.”

Amanda Simpson, former deputy assistant Secretary for Energy under the Obama administration who also directed the U.S. Army Office of Energy Initiatives, found Lieuwen’s remarks timely and on target. The former VP for Research and Technology and head of Sustainability for Airbus Americas said that the aviation sector has grappled with the question of whether net zero by 2050 is the right commitment.

“While it’s an admirable goal, is it a realistic? It’s a very expensive and difficult goal,” she said.
Simpson added that addressing the CO2 issue in aviation is also hard, and she agreed with Lieuwen that it’s easier to decarbonize something on the ground.

“There’s so much to be done in the remaining 26 years, we have to go after everything. There is not going to be a silver bullet – we have to tackle everything to start bringing the [greenhouse gas usage] totals back,” she said.

AFRL Digital Transformation Champion Urges People to Embrace, Not Fear AI

By Anne Wainscott-Sargent, AIAA Communications Team

ORLANDO, Fla. – If Alexis Bonnell had her way, every person would embrace Artificial Intelligence (AI) fearlessly as a tool that gives them back “minutes for their mission” and enables them to “tackle the toil” of mundane work tasks.

The charismatic former Googler, now serving as chief information officer and director of Digital Capabilities Directorate for the Air Force Research Lab (AFRL), believes technology fails when it fails to serve people.

While AI and generative AI promise to bring new efficiencies to all industries and in many instances, reinvent how work is done, it also is a transformative force that many people fear will take away their livelihoods. According to Bonnell, the way the work world packages and frames AI makes it difficult for people to accept the tool.

The visionary behind AFRL’s digital transformation doesn’t talk or act like a typical government executive. Speaking before a standing-room-only crowd at the 2025 AIAA SciTech Forum, she stood out among the room of business-dress-attired engineers and managers, wearing a red top, dark jeans and star-studded knee-high boots. She donned multiple black rubber wristbands with her favorite AI catch phrases that she gave away as keepsakes to inquisitive attendees following her talk.

Bonnell’s presentation included advice on bringing about necessary cultural change in how workers and managers view AI, using insights of what she’s learned from her team’s rollout of NIPRGPT, AFRL’s AI Research Platform to explore the power of Generative AI technology. Launched in June, NIPRGPT’s base of volunteer users grew to about 80,000 in four months, reported InsideDefense. Interest in access to AI tools across the Department of Defense shows no signs of slowing.

In a June 2024 news release announcing the tool, Bonnell noted that “changing how we interact with unstructured knowledge is not instant perfection; we each must learn to use the tools, query, and get the best results. NIPRGPT will allow Airmen and Guardians to explore and build skills and familiarity as more powerful tools become available.”

To the AIAA SciTech Forum’s technical audience, she cautioned that some of her insights may be wrong in six months and “that’s okay…. We’re in an era where we may not have the time for the right answer, so we have to become comfortable with ‘right for now,’ be willing to learn and pivot,” she said. She added that when she thinks about generative AI, she doesn’t think about it as a source of answers, but “as a source of options.”

In answering why the world is clamoring to AI tools now, Bonnell said it’s important to realize that “we now live in a fundamentally different age” – one where people in leadership roles must make decisions and adapt quickly and pivot as conditions change. Consider that 90% of the world’s data was created in the last three years, with 94% of it what Bonnell called unstructured “deluges.”

A sign of the changing times is also evident in battlefield decision-making trends. In the war between Russia and Ukraine, Bonnell said the time frame for Russia countering Ukraine’s software has shrunk, in some cases, to only two weeks. That kind of speed requires new information tools and the ability to make decisions fast. As a result, “we have to think about our technology differently than we did before.”

Bonnell dislikes the mixed messages people have historically received about AI: “We tell people we trust you with a weapon, with a $100M budget, with a security clearance and lots of sensitive information, but we don’t trust you with ChatGPT. What are we actually telling people?” she questioned. “It’s important that we make people feel like they are enough, that they’ve got this, that they are capable, and that we trust them to use tools in the right way. Our future as humans is constant adaptation, the only group that benefits when we are afraid of our own technology is the adversary.”

The technologist noted that the world is not communicating the value of AI in the right way; instead, the first thing people hear is that it’s really complicated, technical, and hard. “That kind of tells someone, ‘You’re not smart enough.’”

She urged a change in the AI narrative and a recognition that as public servants and military personnel, they are showing up to their jobs to be intentional and responsible.

The AFRL leader emphasized the main job of AI in its first phase of human adoption is to simplify and shave off time of mundane work, so people can gain back “minutes for their mission.” That’s exactly what the coders and developers on the AI Research Platform have realized: they report that they have gotten between 25–85% in productivity return using AI tools, Bonnell said.

Bonnell noted that AI and genAI are fundamentally different than other technologies because of the level of intimacy of knowledge that the tools deliver.

“Users get to collect information and the data that they think is relevant and then they use the tool to have a curiosity-based relationship with that data.”

Bonnell has observed at AFRL that her team is leveraging genAI to create a “knowledge universe” around themselves without needing to ask her for information, a discovery that has prompted her to rethink her role as a leader. She challenged other people in CIO roles to be similarly introspective: “For those of in roles like CIOs, it’s a question of how are we going to show up? Are we going to be a gatekeeper or are we going to be a facilitator? There’s a lot of interesting things this is putting into motion.”

In her case, Bonnell is looking at how she can get out of the way of this curiosity journey. “How do I foster the ability for someone to need me less and be able to have a dynamic relationship with knowledge?”

After the presentation, several attendees expressed their appreciation for Bonnell’s take on the state of AI attitudes, workplace culture, and the need to lead differently.

“I like how she talked about coming from the direction ‘see what we can do here’ instead of from a caution perspective of ‘I don’t know if we can do that’ to an attitude of ‘let’s figure out how we can make this work,’” said Christine Edwards, a fellow of AI and Autonomy at Lockheed Martin, whose work includes providing cognitive assistance for firefighters and looking at how to use AI to improve spacecraft operations.

Edwards also enjoyed Bonnell’s insights about trust and AI. “She said it’s less about whether I trust this new technology and more about ‘do I have the confidence that it’s going to have the performance I need for this particular part of my mission?’ I really like that perspective shift.”

John Reed, chief rocket scientist at United Launch Alliance, said he appreciated that Bonnell provided tools for mitigating some of the fear the workforce has about AI. “That’s helpful to think through the stages and the fact that there are going to be people who are concerned, ‘Is this going to eat my job?’  It’s really an augmentation technology just like machine learning. It’s best employed when it’s done to augment the algorithms we’re doing today to make it more effective,” he explained.

The talk also resonated deeply with Marshall Lee, senior director of business development at Studio SE Ltd., a consulting firm focused on model-based systems engineering (MBSE) training and coaching.

“Us engineers are all about the tool, the technology, the formula, the detail. She’s really addressing the changes in brain chemistry and emotion [necessary] for the adoption of the technology,” said Lee. “She’s actually saying you have to change the psychology of the person first before they are going to adopt the new technology. It’s all about that emotion and behavior change and understanding people, starting with where they are.”
