The Sky’s the Limit: Researching surface impacts to improve the durability of aircraft
Associate professor Ibrahim Guven, Ph.D. from the Department of Mechanical and Nuclear Engineering is conducting a research project funded by the Department of Defense (DoD) that explores building aircraft for military purposes and civilian transportation that can travel more than five times the speed of sound. Guven’s role in this project is to consider the durability of aircraft surfaces against elements such as rain, ice, and debris. His research group is composed of Ph.D. students who assist with the study and has collaborated with other institutions, including the University of Minnesota, Stevens Institute of Technology and the University of Maryland. Why did you get involved with this research project? The intersection of need and our interests decides what we research. I’m interested in physics and have been working on methods to strengthen aircraft exteriors against the elements for 12 years. We started with looking at sand particle impact damage, and then we graduated from that to studying raindrop impact because that’s a more challenging problem. Sand impact is not as challenging in terms of physics. A liquid and a solid behave differently under impact conditions. The shape of the raindrop changes prior to the impact due to the shock layer ahead of the aircraft. Researching this impact requires simulating the raindrop-shock layer interaction that gives us the shape of the droplet at the time of contact with the aircraft surface. Unlike with sand, analyzing raindrop impact starts at that point, which requires accurate modeling of the pressure being applied. As the aerospace community achieves faster speeds, there’s a need to understand what will affect a flight’s safety and the aircraft’s structural integrity. That need is what I’m helping to fulfill. Were there any challenges you and your research group faced while working on this study? How did you overcome them? Finding data was hard. I’m a computational scientist, meaning I implement mathematical differential equations that govern physics to write computer code that predicts how something will behave. My experiments are virtual, so to ensure that my models work well, I need experimental data for validation. However, conducting experiments on this problem is extremely challenging. That’s the roadblock. Currently, we refer to data from the seventies and eighties. Beyond that, this kind of information is not available. We are working to generate data that my computational methods need for their validation. An example is the nylon bead impact experiment. Some researchers found that if you shoot a nylon bead at a target, it leads to damage similar to that from a raindrop of the same size. It is much easier and cheaper to shoot nylon beads compared to the experiments involving raindrops. However, this similarity vanishes as we go into higher velocities. How do you typically gather data for a project of this nature? We are working with a laboratory under the U.S. Navy. They can accelerate specimens to relevant speeds, meaning they can shoot them into the air at the desired velocity. A colleague at Stevens Institute of Technology also came up with a droplet levitator. He uses acoustic waves emitted by tiny speakers to play a certain sound at a certain frequency to create enough air pressure to suspend droplets midair. To an untrained eye, it looks like magic. They levitate droplets and use a railgun to shoot our samples at the droplets. Our samples hitting the droplets are stand-ins for the aircraft surface material. Once this is done successfully, they shoot a sample with high-speed cameras that can take ten million frames per second. As a result, we get a good, high-fidelity picture of this impact event. That is the type of data I’m seeking, and this is how I get it from my collaborators. What was your overall experience working with the students in your research group? I like to think it was positive. I try to be a nice advisor and give them space to explore, fail, and bring their own ideas. Even if I feel like we’re at a dead-end, I step back and let them figure it out. My role is to help them grow. Teach them, train them and help them along the way. That’s the experience. Did you notice any personal changes in your students during this project? Yeah, I have. When they’re just out of their undergraduate programs, confidence is lacking sometimes. You see them become more sure of themselves as they learn more and more. Often, regardless of whether English is their native language or not, writing is a big issue for every student. How one presents ideas in written form is a persistent problem in engineering. I see the most growth in that area. Again, an advisor has to be a guide and also have patience. Eventually, after working on multiple paper drafts, I can see tremendous improvement. You must allow them to see their shortcomings. It’s important to work with students to refine how they frame a problem, explain it to a wide audience in concise terms, and use neutral language without leading them to certain conclusions. Why do you think that this research is important? Somebody has to do it, right? I believe that I’m the right person because of my background. Personally, I think if this research makes for safer travel conditions, and if I have something to offer, then why not? If we can accurately simulate what happens in these conditions, we can use our methods to test out designs for damage mitigation. For example, we can perform simulations with different surface materials for the aircraft to see if using a different material or layered coating system leads to less damage. In a bigger picture, we’re working on a very narrow problem in our field, but we don’t know how useful that’s going to be in 10, 15 or 30 years from now. Whatever we study and put out there in terms of publications, it may help some other researcher in a different context many years later. This could be space research, modeling an atmosphere on a different planet, or something that is related to our bodies. There are parts of physics in this problem that do not necessarily only apply to high-speed flight. It could be many different things. One has to understand that what is studied may seem obscure today, but because the universe is more or less governed by the same physics, everything should be put in a theoretical framework, done right and shared with the community. People may learn things that could become relevant in the future. It’s not uncommon. What is another subject that you plan to study? The next natural step is coming up with strategies to mitigate damage in these scenarios. If avoiding a risk is not an option, can we actually come up with a solution? We have to determine how to modify an aircraft’s design to prevent a catastrophe. Another extension of my research would be to examine the landing of spacecraft on dusty planetary bodies. During landing on Earth, aircraft approach and reach the ground very smoothly. On the other hand, a spacecraft comes down slowly and needs a lot of reverse propulsion for a soft landing. As it does, it kicks up a large amount of dust, which blows back and hits the spacecraft. Taking into account the damage that occurs due to particle impact is a direct connection to my work. This again is an open area, and because we have ambitions to have a permanent presence on dusty places like the moon and Mars, we have to nail down the concept of landing safely. That is where my research could help.
Twenty years ago, Hurricane Katrina hit the southeastern coast of the United States, devastating cities and towns across Louisiana, Florida, Mississippi, Alabama and beyond. The storm caused nearly 1,400 fatalities, displaced more than 1 million people and generated over $125 billion in damages. Rob Traver, PhD, P.E., D. WRE, F.EWRI, F.ASCE, professor of Civil and Environmental Engineering at Villanova University, assisted in the U.S. Army Corps of Engineers' (USACE) investigation of the failure of the New Orleans Hurricane Protection System during Hurricane Katrina, and earned an Outstanding Civilian Service Medal from the Commanding General of USACE for his efforts. Dr. Traver reflected on his experience working in the aftermath of Katrina, and how the findings from the investigation have impacted U.S. hurricane responses in the past 20 years. Q: What was your role in the investigation of the failure of the New Orleans Hurricane Protection System? Dr. Traver: Immediately after Hurricane Katrina, USACE wanted to assess what went wrong with flood protections that had failed during the storm in New Orleans, but they needed qualified researchers on their team who could oversee their investigation. The American Society of Civil Engineers (ASCE), an organization I have been a part of for many years, was hired for this purpose. Our job was to make sure that USACE was asking the right questions during the investigation that would lead to concrete answers about the causes of the failure of the hurricane protection system. My team was focused on analyzing the risk and reliability of the water resource system in New Orleans, and we worked alongside the USACE team, starting with revising the investigation questions in order to get answers about why these water systems failed during the storm. Q: What was your experience like in New Orleans in the aftermath of the hurricane? DT: My team went down to New Orleans a few weeks after the hurricane, visited all the sites we were reviewing and met with infrastructure experts along the way as progress was being made on the investigation. As we were flying overhead and looking at the devastated areas, seeing all the homes that were washed away, it was hard to believe that this level of destruction could happen in a city in the United States. As we started to realize the errors that were made and the things that went wrong leading up to the storm, it was heartbreaking to think about how lives could have been saved if the infrastructure in place had been treated as one system and undergone a critical review. Q: What were the findings of the ASCE and USACE investigation team? DT: USACE focused on New Orleans because they wanted to figure out why the city’s levee system—a human-made barrier that protects land from flooding by holding back water—failed during the hurricane. The city manages pump stations that are designed to remove water after a rainfall event, but they were not well connected to the levee system and not built to handle major storms. So, one of the main reasons for the levee system failure was that the pump stations and levees were not treated as one system, which was one of the causes of the mass flooding we saw in New Orleans. Another issue we found was that the designers of the levee system never factored in a failsafe for what would happen if a bigger storm occurred and the levee overflowed. They had the right idea by building flood protection systems, but they didn’t think that a larger storm the size of Katrina could occur and never updated the design to bring in new meteorological knowledge on size of potential storms. Since then, the city has completely rebuilt the levees using these lessons learned. Q: What did researchers, scientists and the general population learn from Katrina? DT: In areas that have had major hurricanes over the past 20 years, it’s easy to find what went wrong and fix it for the future, so we don’t necessarily worry as much about having a hurricane in the same place as we’ve had one before. What I worry about is if a hurricane hits a new town or city that has not experienced one and we have no idea what the potential frailties of the prevention systems there could be. Scientists and researchers also need to make high-risk areas for hurricane activity in the United States known for those who live there. People need to know what their risk is if they are in areas where there is increased risk of storms and flooding, and what they should do when a storm hits, especially now with the changes we are seeing in storm size.

The Commonwealth Cyber Initiative’s (CCI) Northern Virginia Node recently awarded a $75,000 grant to Supriyo Bandyopadhyay, Ph.D., professor in the Department of Electrical and Computer Engineering at the Virginia Commonwealth University (VCU) College of Engineering, to develop an ultra-subwavelength microwave polarization switch for secure communication. The one-year grant comes through the Cyber Acceleration, Translation and Advanced Prototyping for University Linked Technology (CATAPULT) Fund. It supports Bandyopadhyay’s project, “An ultra-subwavelength microwave polarization switch for secure communication,” which develops a nanomagnet-based antenna integrated with a piezoelectric component. This system can switch the polarization of electromagnetic beams at specific microwave frequencies to enable secret communication between two points without traditional encryption methods. “Secret communication sheds the need for encryption,” Bandyopadhyay said. “Any cryptography can be broken, but this scheme does not use cryptography for secret communication and does not suffer from this vulnerability. It is also entirely based on hardware and cannot be hacked.” The technology offers significant benefits for banking, healthcare and government communications where data security is critical because a hardware-based approach makes it immune to software hacking. Another result of the research is antenna miniaturization, with antenna sizes several orders of magnitude smaller than the radiated wavelength. This addresses limitations in algorithms, physical size and power requirements that current secure communication systems face. Bandyopadhyay is collaborating with two researchers from the Department of Electrical and Computer Engineering at Virginia Tech and Erdem Topsakal, Ph.D., senior associate dean for strategic initiatives and professor in the Department of Electrical and Computer Engineering at VCU. Students involved in the project will be trained in antenna engineering, microwaves and communication engineering, gaining skills increasingly vital in today’s connected world.

He also explores AI’s ability to improve human-machine interactions. With his accomplished background and experience at national defense labs, Dhar bridges classroom theory with practical engineering challenges his students will face in their careers. “It feels incredible to be recognized this way. Virginia Commonwealth University truly values faculty who pour themselves into student success and university growth. What really drives me is knowing I’m helping build the next generation of problem-solvers. That’s where the real satisfaction comes from.” said Dhar. This promotion encourages Dhar to make bigger strides for research development that will transform both teaching methods and how technology advances in military and commercial sectors.
First AI-powered Smart Care Home system to improve quality of residential care
Partnership between Lee Mount Healthcare and Aston University will develop and integrate a bespoke AI system into a care home setting to elevate the quality of care for residents By automating administrative tasks and monitoring health metrics in real time, the smart system will support decision making and empower care workers to focus more on people The project will position Lee Mount Healthcare as a pioneer of AI in the care sector and opening the door for more care homes to embrace technology. Aston University is partnering with dementia care provider Lee Mount Healthcare to create the first ‘Smart Care Home’ system incorporating artificial intelligence. The project will use machine learning to develop an intelligent system that can automate routine tasks and compliance reporting. It will also draw on multiple sources of resident data – including health metrics, care needs and personal preferences – to inform high-quality care decisions, create individualised care plans and provide easy access to updates for residents’ next of kin. There are nearly 17,000 care homes in the UK looking after just under half a million residents, and these numbers are expected to rise in the next two decades. Over half of social care providers still retain manual and paper-based approaches to care management, offering significant opportunity to harness the benefits of AI to enhance efficiency and care quality. The Smart Care Home system will allow for better care to be provided at lower cost, freeing up staff from administrative tasks so they can spend more time with residents. Manjinder Boo Dhiman, director of Lee Mount Healthcare, said: “As a company, we’ve always focused on innovation and breaking barriers, and this KTP builds on many years of progress towards digitisation. We hope by taking the next step into AI, we’ll also help to improve the image of the care sector and overcome stereotypes, to show that we are forward thinking and can attract the best talent.” Dr Roberto Alamino, lecturer in Applied AI & Robotics with the School of Computer Science and Digital Technologies at Aston University said: “The challenges of this KTP are both technical and human in nature. For practical applications of machine learning, it’s important to establish a common language between us as researchers and the users of the technology we are developing. We need to fully understand the problems they face so we can find feasible, practical solutions. For specialist AI expertise to develop the smart system, LMH is partnering with the Aston Centre for Artificial Intelligence Research and Application (ACAIRA) at Aston University, of which Dr Alamino is a member. ACAIRA is recognised internationally for high-quality research and teaching in computer science and artificial intelligence (AI) and is part of the College of Engineering and Physical Sciences. The Centre’s aim is to develop AI-based solutions to address critical social, health, and environmental challenges, delivering transformational change with industry partners at regional, national and international levels. The project is a Knowledge Transfer Partnership. (KTP). Funded by Innovate UK, KTPs are collaborations between a business, a university and a highly qualified research associate. The UK-wide programme helps businesses to improve their competitiveness and productivity through the better use of knowledge, technology and skills. Aston University is a sector leading KTP provider, ranked first for project quality, and joint first for the volume of active projects. For more information on the KTP visit the webpage.
A Virginia Commonwealth University researcher has developed an alternative method of producing semiconductor materials that is environmentally friendly. Semiconductors are crucial to modern electronics and displays, but they are constructed from toxic solvents. They also are created at high temperatures and pressures, resulting in both environmental damage and high production costs. The new technique has been introduced by Leah Spangler, Ph.D., assistant professor in the VCU College of Engineering’s Department of Chemical and Life Science Engineering, and Michael Hecht, a professor of chemistry at Princeton University. It demonstrates an alternative method to produce semiconductor materials called quantum dots using proteins at room temperature in water, resulting in a more environmentally friendly synthesis method. “This research uses de novo proteins, which are not taken from natural organisms but instead made by design for specific purposes,” Spangler said. “Therefore, this work shows that protein design can be leveraged to control material properties, creating an exciting new direction to explore for future research.” This work builds on natural examples of proteins creating materials, known as biomineralization. But this is the first example that uses de novo proteins made by design to control the synthesis of quantum dots. The study, “De Novo Proteins Template the Formation of Semiconductor Quantum Dots,” was published in the journal ACS Central Science. The work is related to a recent Department of Defense grant to Spangler to test an eco-friendly approach for separating rare earth elements into a refined final product using de novo proteins.
