Southwest Research Institute produced a batch of blended sustainable aviation fuel (SAF) through a refinery process that started with electrofuels or e-fuels made from carbon dioxide and green hydrogen. Using internal research funding, a multidisciplinary team produced and characterized the SAF, along with two other commercially available fuels, before collecting emissions and particulate data to support the aviation industry’s emissions goals.

“Aviation is difficult to decarbonize due to the fuel density and power required for flight,” said Francesco Di Sabatino, a group leader in SwRI’s Mechanical Engineering Division. “With this project we’re gathering important data for conventional fuel and two different SAFs.”

Conventional jet fuel is made from petroleum that burns inside a jet engine. Fueling jets with SAF could help reduce carbon emissions. Worldwide air travel accounts for 2% of all carbon emissions, and 12% of all carbon emissions from transportation. The team tackled three focus areas — production, characterization and testing.

Sikorsky, a Lockheed Martin company started its first-ever ground runs on a UH-60M Black Hawk® helicopter equipped with two GE Aerospace T901 Improved Turbine Engines (ITE). During this test, the T901 engine demonstrated its capabilities through a series of rigorous procedures. The initial light off and ground runs were executed by a combined U.S. Army and industry test team and operated by Army and Sikorsky pilots.

“Soldiers will rely on Black Hawk helicopters well into the future, and upgrades to the aircraft today will pay dividends for decades, enabling new missions such as deploying and managing launched effects,” said Hamid Salim, vice president of Army and Air Force Systems at Sikorsky. “A modernized Black Hawk fleet will create new operational opportunities for the Army by extending the capabilities of a proven, fielded fleet to travel farther on less fuel and with more troops and cargo.”

First flight of the ITE-equipped Black Hawk is anticipated this year.

Team makes sustainable aviation fuel additive from recycled polystyrene

Illinois Sustainable Technology Center research scientist Hong Lu and his colleagues developed a method for converting waste polystyrene into a sustainable jet fuel additive, ethylbenzene. Their work overcomes a key obstacle to the wider use of sustainable aviation fuels.

A new study overcomes a key challenge to switching commercial aircraft in the U.S. from their near-total reliance on fossil fuels to more sustainable aviation fuels. The study details a cost-effective method for producing ethylbenzene — an additive that improves the functional characteristics of sustainable aviation fuels — from polystyrene, a hard plastic used in many consumer goods. 

The findings are reported in the journal ACS Sustainable Chemistry and Engineering.  

Fuels derived from waste fat, oil, grease, plant biomass or other nonpetroleum sources lack sufficient levels of aromatic hydrocarbons, which help keep fuel systems operational by lubricating mechanical parts and swelling the seals that protect from leaks during normal operations, said Hong Lu, a research scientist at the Illinois Sustainable Technology Center who led the new research. ISTC is a division of the Prairie Research Institute at the University of Illinois Urbana-Champaign. 

While ethylbenzene is an aromatic hydrocarbon and can be derived from fossil fuels, finding a sustainable way to produce it would aid the aviation industry’s conversion to sustainable jet fuels. 

More than flying cars: eVTOL battery analysis reveals unique operating demands

The operating phases of an eVTOL need varying amounts of power; some require the battery to discharge high amounts of current rapidly, reducing the distance the vehicle can travel before its battery must be recharged.

Researchers at the Department of Energy’s Oak Ridge National Laboratory are taking cleaner transportation to the skies by creating and evaluating new batteries for airborne electric vehicles that take off and land vertically. 

These aircraft, commonly called eVTOLs, range from delivery drones to urban air taxis. They are designed to rise into the air like a helicopter and fly using wing-borne lift like an airplane. Compared with helicopters, eVTOLs generally use more rotors spinning at a lower speed, making them both safer and quieter.

The airborne EV’s aren’t just flying cars, and ORNL researchers conclude that eVTOL batteries can’t just be adapted from electric car batteries. So far that has been the dominant approach to the technology, which is mostly in the modeling stage. ORNL researchers took a different tack by evaluating how lithium-ion batteries fare under extremely high-power draw. 

“The eVTOL program presents a unique opportunity for creating a brand-new type of battery with very different requirements and capabilities than what we have seen before," said Ilias Belharouak, an ORNL Corporate Fellow who guides the research.

Sikorsky, a Lockheed Martin company, today unveiled its plan to build, test and fly a hybrid-electric vertical takeoff and landing demonstrator (HEX / VTOL) with a tilt-wing configuration.

The design is the first in a series of large, next generation VTOL aircraft — ranging from more traditional helicopters to winged configurations — which will feature varying degrees of electrification, and an advanced autonomy system for optionally piloted flight.

“We never stop innovating at Sikorsky,” said Sikorsky President Paul Lemmo. “Autonomy and electrification will bring transformational change to flight safety and operational efficiency of large VTOL aircraft. Our HEX demonstrator program will provide valuable insights as we look to a future family of aircraft built to the scale and preferred configurations relevant to commercial and military customers.”

The HEX program will put a premium on greater than 500 nautical mile range at high speed, fewer mechanical systems to reduce complexity, and lower maintenance costs.

Lockheed Martin presented Belgium's first F-35A Lightning II to the Belgian government during a rollout ceremony at Lockheed Martin's F-35 production facility. This event marks a significant milestone in the Belgian Air Force's history and strengthens the alliance between the United States and Belgium, a key NATO ally.  

"The introduction of the F-35 within the Belgian Air Force will enable us to continue to fulfil all our missions in the coming decades, in cooperation with our allies and partners in NATO, the EU and beyond," said Chief of Defense for the Belgian Armed Forces, Admiral Michel Hofman.

Building on the strong legacy of the F-16, the F-35 will provide the next generation of air power to ensure the Belgian Air Force can fulfill its NATO missions and protect the alliance's key interests. By serving as the most advanced 21st Century Security solution, the F-35 will connect assets across domains to increase situational awareness for Belgium and its key European partners. 

"We congratulate Belgium on this significant achievement," said Lt. Gen. Mike Schmidt, program executive officer, F-35 Joint Program Office. "The growth of the F-35 in Europe strengthens international partnerships, interoperability, and warfighting capability; and emphasizes the importance the aircraft provides as a deterrent against potential adversaries." 

General aviation sector grounded by red tape and sky-high costs

Red tape, over-regulation, spiraling costs and a vacuum of government policy are putting significant pressure on the general aviation sector in Australia, according to a survey of industry chiefs.

Ageing infrastructure, thin profit margins and conflicts over airspace allocation are all contributing to pessimism in the non-airline civil aviation sector that employs thousands of people.

In a new paper published this month in Case Studies on Transport Policy, aviation experts from Queensland and the University of South Australia (UniSA) outline the issues plaguing the industry, most of which come down to a lack of policy direction in aviation.

The sector includes training, aeromedical, emergency response and charter services in rural and remote communities.

Interviews conducted with the principals of 21 aviation organizations reveal that outside of regulation, the main concerns are the costs associated with operating premises and airport infrastructure.

A Boeing and Nammo team set a record for longest indirect fire test of a ramjet-powered artillery projectile alongside officials from the U.S. Army — firing a Ramjet 155 munition from a 58-caliber Extended Range Cannon Artillery (ERCA) at Yuma Proving Ground, Ariz. The test advances development efforts for the Army’s top modernization priority, Long Range Precision Fires.

“Our objective was to demonstrate the ability to safely operate from the ERCA system and validate our performance. Both objectives were met.” said Gil Griffin, executive director of Boeing Phantom Works. “The team is working to deliver a superior, affordable precision strike weapon that can neutralize critical targets at long distances.”

The success follows last year’s Boeing-Nammo test recording the longest-ever indirect fire test of a Ramjet 155 munition. That test was completed using a 39-caliber towed artillery cannon at the Andøya Test Center in Norway.

AI copilot enhances human precision for safer aviation

With Air-Guardian, a computer program can track where a human pilot is looking (using eye-tracking technology), so it can better understand what the pilot is focusing on. This helps the computer make better decisions that are in line with what the pilot is doing or intending to do.

Imagine you're in an airplane with two pilots, one human and one computer. Both have their “hands” on the controllers, but they're always looking out for different things. If they're both paying attention to the same thing, the human gets to steer. But if the human gets distracted or misses something, the computer quickly takes over.

Meet the Air-Guardian, a system developed by researchers at the MIT Computer Science and Artificial Intelligence Laboratory (CSAIL). As modern pilots grapple with an onslaught of information from multiple monitors, especially during critical moments, Air-Guardian acts as a proactive copilot; a partnership between human and machine, rooted in understanding attention.

But how does it determine attention, exactly? For humans, it uses eye-tracking, and for the neural system, it relies on something called "saliency maps," which pinpoint where attention is directed. The maps serve as visual guides highlighting key regions within an image, aiding in grasping and deciphering the behavior of intricate algorithms. Air-Guardian identifies early signs of potential risks through these attention markers, instead of only intervening during safety breaches like traditional autopilot systems.

To support the development of a revolutionary new open fan engine architecture for the future of flight, GE Aerospace has run simulations using the world’s fastest supercomputer capable of crunching data in excess of exascale speed, or more than a quintillion calculations per second.

To model engine performance and noise levels, GE Aerospace created software capable of operating on Frontier, a recently commissioned supercomputer at the U.S. Department of Energy’s (DOE) Oak Ridge National Laboratory with processing power of about 37,000 GPUs. For comparison, Frontier’s processing speed is so powerful, it would take every person on Earth combined more than four years to do what the supercomputer can in one second.  

By coupling GE Aerospace’s computational fluid dynamics software with Frontier, GE was able to simulate air movement of a full-scale open fan design with incredible detail.

“Developing game-changing new aircraft engines requires game-changing technical capabilities. With supercomputing, GE Aerospace engineers are redefining the future of flight and solving problems that would have previously been impossible,” said Mohamed Ali, vice president and general manager of engineering for GE Aerospace.

Two teams -- General Atomics working with Maritime Applied Physics Corporation and Aurora Flight Sciences working with Gibbs & Cox and ReconCraft -- will develop designs for DARPA’s Liberty Lifter Seaplane Wing-in-Ground Effect full-scale demonstrator. The Liberty Lifter program aims to demonstrate a leap-ahead in operational capability by designing, building, floating, and flying a long-range, low-cost X-Plane capable of seaborne strategic and tactical heavy lift.

The planned Liberty Lifter demonstrator will be a large flying boat similar in size and capacity to the C-17 Globemaster III transport aircraft. Goals include takeoff and land in Sea State 4, sustained on-water operation up to Sea State 5, and extended flight close to the water in ground effect with the capability to fly out of ground effect at altitudes up to 10,000 feet above sea level.

“We are excited to kick off this program and looking forward to working closely with both performer teams as they mature their point-of-departure design concepts through Phase 1,” said DARPA Liberty Lifter Program Manager Christopher Kent. “The two teams have taken distinctly different design approaches that will enable us to explore a relatively large design space during Phase 1.”
