SwRI receives $23 million in U.S. Air Force contracts to sustain aging aircraft

Institute to help maintain structural integrity of three fleets of military aircraft

2024-11-04

(Press-News.org) SAN ANTONIO — November 4, 2024 —Southwest Research Institute has received two contracts totaling $23 million from the U.S. Air Force for a program to address aging aircraft structures and material degradation. Under these contracts, the Institute will help the Air Force modernize methods to sustain the T-38 Talon, the A-10 Thunderbolt and the B-52 Stratofortress. All three military aircraft first came into service more than 45 years ago.

“SwRI will assist with the full spectrum of structural sustainment for these aircraft,” said Luciano Smith, manager of SwRI’s Structural Integrity Group. “Our analyses will help the Air Force know when, where and how often to inspect the aircraft to determine when structural repairs are necessary.”

For several decades, SwRI has provided technical engineering support to the Air Force to extend the life of aircraft that came into service in the ‘60s and ‘70s and that have exceeded their design life. Under these new contracts, the Institute will help manage the structural integrity of the A-10 Thunderbolt II, a close air support attack aircraft first introduced in 1976, and the T-38 Talon, a two-seat supersonic training aircraft introduced in 1961.

“SwRI has worked with the Air Force to maintain the structural integrity of the A-10 for more than 20 years and the T-38 for more than 40,” said David Wieland, who oversees the Institute’s Aerospace Structures Section. “Under these new contracts, we will perform design, analyses, testing and nondestructive inspections. We will also evaluate flight data recording, usage monitoring and individual aircraft tracking systems.”

SwRI will also help maintain the B-52 Stratofortress, a strategic heavy bomber manufactured in the 1950s. The structural integrity and performance of all three fleets of aircraft will also be evaluated under simulated real-world conditions. Work on the fleets has already begun.

Since beginning structural integrity work for the Air Force in the early 1970s, SwRI has developed tools in support of that effort, including a flight data recording system to help engineers understand the structural stresses associated with various flight maneuvers, and the NASGRO® software tool, a collaboration with NASA that can analyze fracture and fatigue crack growth in structures and mechanical components. Additionally, SwRI has created specialized inspection probes and nondestructive systems to inspect through bushings without removal, which is currently undergoing probability of detection study.

Security in quantum computing

2024-11-04

Alongside artificial intelligence, quantum computing is one of the fastest-growing subsets in the high-performance computing community. But what happens when this relatively new and powerful computing method reaches the limit of the cyberinfrastructure and network security capabilities of today? Researchers at the National Center for Supercomputing Applications are addressing this issue before it becomes a problem. “The problem is urgent because practical quantum computers will break classical encryption in the next decade,” ...

Noninvasive choroidal vessel analysis via deep learning: A new approach to choroidal optical coherence tomography angiography

2024-11-04

Researchers from Peking University have developed a novel noninvasive choroidal angiography method that enables layer-wise visualization and evaluation of choroidal vessels using deep learning. This new approach, published in Health Data Science, employs an advanced segmentation model that can handle varying quality of optical coherence tomography (OCT) B-scans, making it a promising tool for clinical applications in diagnosing retinal diseases. Choroidal Optical Coherence Tomography Angiography (C-OCTA) offers a significant improvement in the analysis of choroidal vessels, a critical component in the ...

National Multiple Sclerosis Society awards $1M to Case Western Reserve University researchers to study new approach to treat the disease

2024-11-04

CLEVELAND—Multiple sclerosis (MS) is a debilitating disease of the brain and spinal cord that impacts millions worldwide. In MS, the immune system mistakenly attacks the myelin sheath—a protective layer surrounding nerve cells in the nervous system. The loss of myelin, combined with ongoing inflammation, causes dysfunction and death of nerve cells, making the disability worse, such as difficulties with movement, coordination, and sensation. Treatments now focus on reducing attacks on myelin, but don’t address nerve-cell damage and death. But with $1 million from the National Multiple ...

Virginia Tech researchers find menthol restrictions may drive smokers to healthier alternatives

2024-11-04

Nationwide, fewer people smoke than did a decade ago, but the proportion who smoke menthol-flavored cigarettes is on the rise. More than 9 million adults, or about 32 percent of all smokers, use menthol cigarettes, according to the Centers for Disease Control and Prevention. In Virginia, the proportion stands higher, at 38 percent. A team of researchers including Roberta Freitas-Lemos, assistant professor at Virginia Tech’s Fralin Biomedical Research Institute at VTC, found that if menthol products were unavailable, smokers found replacement therapies such as nicotine gum and lozenges were practical alternatives, potentially improving health outcomes for people who use menthol ...

Japanese study reveals the importance of new overtime restrictions on physician’s mental health

2024-11-04

Physicians are a vital component of the healthcare landscape and along with other medical professionals, they ensure timely diagnosis, treatment, and management of complex illnesses. They regularly work extended and overnight shifts, often at the cost of sleep. However, the long duty hours of physicians can lead to physical and mental exhaustion, resulting in negative consequences such as depression and burnout. Consequently, this can affect their level of alertness and thus the quality of patient care. To protect the health of Japanese physicians, a duty hour reform went into effect ...

The research underscores the importance of identifying individuals with past concussions early in their prenatal care and highlights the need for long-term, trauma-informed support to safeguard their mental health. “We found that individuals with a history of concussion were significantly more likely to experience serious mental health challenges, ...

Combining two simple tools could combat election misinformation

2024-11-04

ITHACA, N.Y. – A popular new strategy for combatting misinformation doesn’t by itself help people distinguish truth from falsehood but improves when paired with reminders to focus on accuracy, finds new Cornell University-led research supported by Google. Psychological inoculation, a form of “prebunking” intended to help people identify and refute false or misleading information, uses short videos in place of ads to highlight manipulative techniques common to misinformation, such as emotional language, false dichotomies and scapegoating. The strategy has already been deployed ...

Nanoscale transistors could enable more efficient electronics

2024-11-04

CAMBRIDGE, MA – Silicon transistors, which are used to amplify and switch signals, are a critical component in most electronic devices, from smartphones to automobiles. But silicon semiconductor technology is held back by a fundamental physical limit that prevents transistors from operating below a certain voltage. This limit, known as “Boltzmann tyranny,” hinders the energy efficiency of computers and other electronics, especially with the rapid development of artificial intelligence technologies that demand faster computation. In an effort to overcome this fundamental limit of silicon, MIT researchers fabricated a different type ...
