Earn your pilot's license

“There was and remains an airline pilot shortage. This program was designed to enhance the pipeline of licensed pilots to address this.” Lance Sherry, associate professor Department of Systems Engineering and Operations Research

Matt Conroe is close to attaining a lofty lifelong goal: becoming a licensed pilot. For this recent ��AV graduate in mechanical engineering, however, something else was pressing this spring, and that wasn’t just getting his ducks in a row to graduate or preparing the final steps for his license. His son Kian was born in April, just nine days before he took part in Commencement.

Conroe graduated with a minor in Aviation Flight Training and Management. “When I was a kid, I was thinking of firefighter, policeman, doctor. But my dad is in the Air Force and has served for 36 years and I thought, ‘I’d like to be a pilot.’”

And will this new dad be grounded by family responsibilities before having the chance to explore the friendly skies? “My wife might have been scared in the beginning,” he said, “but they train you so much that by the time you do your solo flight, you know what to do.”

The minor combines a pilot’s license with aviation management experience, giving students a significant advantage in seeking work with airlines, airports, and in air traffic control.

Business major Hamza Al Tell, who is also just a few steps from obtaining his license, plans to use his experience directly with his family business. Growing up in Jordan, Al Tell’s family ran a skydiving company, and he earned a love of flying at an early age. “I was young, but the captain would let me go up and control the plane a little bit,” he said.

Al Tell loved that he could combine his core degree with his passion. “I was scrolling through minors and saw this one and it was perfect for me. I could do my university studies alongside getting my pilot’s license.”

Lance Sherry, a professor in the Systems Engineering and Operations Research Department, oversees the program. He has more than 30 years of experience in the aviation industry, serving as a flight test engineer, flight control engineer, and system engineer.

"The minor is unique,” he said. “Whether a student is seeking to become an airline or business jet pilot, or to work for an airport, or as an air traffic controller, the program provides a strong foundation of knowledge and skills to be employable anywhere in the industry. The program’s relevance is evident in the career success of our graduates who are shaping a safer, more climate-friendly, socially just air transport system."

The program is ranked 20th in the world, 11th in the United States, and first in the Washington, D.C. region. It began 10 years ago when the university recognized the significant demand for aviation programs in general and flight training specifically.

Sherry said, “There was and remains an airline pilot shortage. This program was designed to enhance the pipeline of licensed pilots to address this.”

“Professor Lance was a great help in all of this," Al Tell said. "When I would see him on the schedule, I would get very excited. Based on his personal experience, he shared with us how the industry works behind the scenes. This was incredible fascinating.”

Conroe added, “I had good professors and I felt like they really cared. They were very professional and knew what they were talking about. You can tell when someone comes in and is really excited.”

“We’ve been nothing but impressed with the caliber and dedication of students who train with us,” said flight instructor Kyle McDaniel, BS Public Administration '10. “As a Mason alum myself, I’m thrilled to share my love of aviation with my alma mater.”

Students win contests designing delivery drones that respond to real-time wind change

Students win contests designing delivery drones that respond to real-time wind change Nathan Kahl Wed, 05/08/2024 - 09:09

Part of the charm of tiny Tangier Island, located smack dab in the middle of the Chesapeake Bay, is that in some ways it seems stuck in time, with residents speaking an outdated dialect and relying on crabbing for a living. What isn’t so endearing to residents about their simple life is the need to take a ferry to the Eastern Shore to obtain necessities, such prescription medications. Such a trip is an all-day affair, often causing people to miss work and lose wages.

But now Riverside Health System and DroneUp, a delivery service based in Virginia Beach, are working with a team of ��AV students to deliver medications via a small drone. But even that poses challenges.

“As a part of my systems engineering senior design project, my team and I performed a context analysis and a stakeholder analysis to find the performance gaps for a case study about drone delivery to an island located in the Chesapeake Bay–Tangier Island,” said senior Diana Machuca, who is majoring in systems and industrial engineering. “To bridge the gaps, we designed the Drone Range Dynamic System and came up with a business plan for the project.”

“The route is 15 nautical miles (NM) from Onley, Virginia, to Tangier Island,” said team member Darius Jack. “The route traverses both land and terrain resulting in significant wind shifts, including onshore and offshore winds, depending on the time of day.”

Depending on a drone’s design, it can be very sensitive to wind, requiring extensive analysis. Team member Grean Ramos said, “We developed an aerodynamic simulation of the drone and its batteries. The simulation showed that the 15 NM route is close to the drone's range limit. Any unexpected headwind could result in the drone running out of battery and needing to land before reaching Tangier Island.”

“There are weather stations at Onley and at Tangier Island airports, but no weather stations in-between," said team member Diana Machuca. "We analyzed one year of hourly wind data from the airports and found that headwinds would prevent the drone from reaching the clinic 32 percent of the time.”

Team members Gurkirt Tahim, Darius Jack, Grean Ramon, and Diana Machuca

So the team developed a Drone Range Decision-support System (DRDS). The DRDS uses the aerodynamic simulation described above to continuously monitor the range-remaining as the drone flies. If the simulation estimates that the drone has experienced an unexpected wind and will no longer have enough battery power to reach the destination, it recommends the drone operator to return home (if it can) or to land safely in designated landing zones. Simulations showed winds would require the drone to return home 17 percent of the time.

The team’s plan won First Place in the STEM Track in the Patriot Pitch Competition, a annual contest sponsored by the Costello College of Business at George Mason, and First Place in the Systems and Analytics Track at the Sage Memorial Design Competition, a student-focused international forum for the design of complex systems.

“Working on this project was an amazing experience,” said Jack. “We had to use all the system engineering knowledge and skills we learned over the past three years. Building systems in the real-world is hard, but perseverance and creativity pay off.”

New College of Engineering and Computing professor Missy Cummings seeks to address challenges in artificial intelligence

New College of Engineering and Computing professor Missy Cummings seeks to address challenges in artificial intelligence Tama Moni Tue, 01/03/2023 - 14:27

As one of the U.S. Navy’s first female fighter pilots and an engineer, Mary “Missy” Cummings is accustomed to breaking barriers and solving problems. So, when the opportunity to develop a new interdisciplinary program in artificial intelligence (AI) at ��AV’s College of Engineering and Computing emerged, she didn’t hesitate.

Cummings wants to increase the public and workforce's understanding of AI and its limits.

For example, self-driving cars have proven to be much more difficult to launch safely than originally believed. Before coming to Mason, Cummings served as the senior safety advisor to the National Highway Traffic Safety Administration. She said that experience sparked her interest in a new program in the design and deployment of AI.

“I believe we have a national security crisis across the Department of Transportation, the Department of Defense, and many other government agencies,” Cummings said. “We have a genuine technical illiteracy problem. It's not that people can't understand AI. It's that people are just not being educated in how AI is constructed or in its limitations.”

Cummings encountered tech illiteracy problems earlier in her career while serving on the Defense Innovation Board.

“I saw the problem then, and now that I've been in the Department of Transportation, it's doubly reinforced my concern about people's limited understanding of AI,” she said.

Cummings wants industry and government employees to know how to ask the right questions about performance weaknesses and understand where to invest tax dollars.

She said she’s concerned the U.S. doesn’t have an effective workforce when it comes to understanding, managing, acquiring, evaluating, and testing AI. She wants people to learn about the right way for humans and AI to work together as well as to learn what is truly attainable and what is merely hype.

“I think traditional academia has a hard time accepting new areas, like a degree program in the design and deployment of AI. Older schools with more ingrained traditions struggle to embrace newer thinking,” she said. “I don't think Mason is like that. Dean Ken Ball and others at the College of Engineering and Computing as well as Mason’s president Gregory Washington have embraced these ideas.”

“Missy’s knowledge and experience surrounding AI are going to be a phenomenal asset to Mason,” Ball said. “Her ability to make connections between computer science, electrical, and mechanical engineering fields and leverage the strengths of each to improve our understanding of AI will be a game changer. We are thrilled she has decided to work with us.”

Cummings is proposing a new degree program in AI that will target engineering students as well as those in policy, law, and public health. “To navigate the world of AI students also need softer skills in policy, and maybe even ethics,” Cummings said.

"I find that Mason is far more flexible and more open to new ideas than older more entrenched schools. At Mason, people are willing to come together from the different colleges and schools to solve real complex sociotechnical problems," she said. "There's not one societal problem we have today that belongs to a sole discipline."

Her faculty appointment spans three departments—Computer Science, Mechanical Engineering, and Electrical and Computer Engineering. She will also be the First American Bank Endowed Chair and Director of the Center for Robotics, Autonomous Systems, and Translational AI. Cummings' scholarly work will include opportunities to work with Fuse at Mason Square faculty and partners. Fuse will launch in 2024.

Since Michael Riggi was about six years old, his father and brother would take him to a “Cars and Coffee” show in Great Falls, Virginia, on weekends. Being around classic automobiles and luxury vehicles, Riggi said he developed an appreciation for cars, and other machines that go fast, including planes, boats, and rockets.

Now, as a junior at ��AV, his career path has also been racing forward.

The systems engineering major working on an accelerated master’s degree is the president of Hypernova Solar, a student organization creating what they believe will be the world’s first 3D-printed solar car.

Ultimately, Riggi said he aspires to work in the aerospace industry. His work with Hypernova Solar combined with his degree helped him land an internship with the global aerospace, defense, and security company, Northrop Grumman, he said.

“[Systems engineering] is in high demand in almost all tech industries,” Riggi said.

“Mason is one of the only schools I found in this area that offered a system engineering major, and Mason’s program was ranked higher than [the University of Virginia]’s,” he said. “I chose Mason off their great program.”

When Riggi interned with Northrop Grumman in summer 2021, he said he worked on spacecraft that go up to the international space station—in particular, the Cygnus Mission. Riggi said his tasks involved taking measurements, estimating error, and creating a CAD model of the thruster.

“We made a tool that allowed Mission Control to quickly throw in measurements of the motors to see how it affects the angle of the spacecraft on-the-fly, so they can steer the spacecraft,” Riggi said.

“The qualities about Michael that impressed me and my colleagues [at Northrop Grumman] were his imagination and ability to tackle a task that was initially beyond the scope of his previous experience,” said Roseann Alvarez, systems engineering manager at Northrop Grumman. “He shows plenty of growth potential and will be an asset to any future employer.”

“Based on Michael’s performance and his contributions to the [Commercial Resupply Services] program, I would highly recommend Northrop Grumman recruitment of Mason interns and graduates in the future,” she said.

Riggi said he’s excited to intern again with Northrop Grumman in summer 2022.

“There’s something about being on the cutting edge of technology and science that I really love,” he said. “[My internship] helped me realize what traits I value in a workplace and helped me realize specific parts of my education to focus on because I’ve seen what’s actually needed in the workforce.”

In addition to opportunities in the Washington, D.C., metropolitan area, Riggi said he has enjoyed learning from supportive Mason professors including John Shortle, Abbas Zaidi, and Colin Reagle.

“Michael embodies the ideal of a systems engineer, being able to assemble and lead a large team of students with diverse skills to design, build, and test a complex system,” Shortle said. “He’s a great ambassador for the discipline and will be a great asset in the workforce.”

When he’s not leading Hypernova Solar, Riggi said he enjoys going off-roading and taking photos.

“It’s really a great way to blow off steam and relax,” Riggi said, suggesting diverse activities help keep his life balanced yet exciting. “If there’s one thing I hate, it’s being bored.”

That’s another reason he appreciates the opportunities at Mason.

“My favorite part of Mason is the community,” Riggi said. “The diverse student population has taught me so much and helped me make so many friends, the amazing faculty have been so helpful, and the community of Fairfax is very diverse and a great space to explore.”

Mechanical engineering students get a close-up look at the Bell 429 helicopter.

Students studying aeronautics in the Department of Mechanical Engineering got an up-close look at how a helicopter works when the Fairfax Police landed one on campus recently and explained its functionality.

Mason Engineering’s second-semester senior aeronautics class (ME 499) focuses on rotary-wing flight vehicle performance, stability/control, and unmanned aircraft systems.

To bring some of the ideas of the class to life, adjunct professor Robert Gallo asked Captain Michael Shamblin, Helicopter Division Commander of the Fairfax County Police Department, to provide a practical demonstration of vertical lift with their Bell 429 helicopter.

The helicopter landed on the lawn outside Merten Hall one afternoon in late February, and the police flight crew demonstrated how the cyclic and collective flight systems affect motion and control of the rotor blades.

Among those attending the class with the aeronautics students were: Mason president Gregory Washington, Provost and Executive Vice President Mark Ginsberg, Volgenau School of Engineering Dean Ken Ball, and Mechanical Engineering Department Chair Leigh McCue.

“YouTube videos and PowerPoints only go so far in explaining the complexities of vertical lift,” Gallo says, “so having the Fairfax Police here helped our students understand how the helicopter rotor generates lift and allows it to fly in all directions.”

Mechanical engineering senior Mason Chee agrees. “We were able to look inside at the controls that they use to pilot a helicopter, and we learned about some of the effects the helicopter encounters during its flight. You can read about the theories and watch videos about them, but nothing comes as close as seeing it live.”

Vanessa Barth, a mechanical engineering senior, adds, “They were teaching us about the mechanical components and systems that control a helicopter. It was all information we talked about in class, but to see it in person was helpful.”

Gallo says the Fairfax Police were highly engaging and did an outstanding job answering questions, not only from our students but also from the faculty and staff in attendance.

A team of ��AV students are among the brains behind a satellite that launched into space this weekend as part of a collaboration with Northrop Grumman and Virginia Space that includes being part of a resupply mission to the International Space Station.

The 14 Mason undergraduate students involved and project advisor Peter Pachowicz watched anxiously on Saturday, Feb. 20, as their ThinSat, a small satellite developed by students that is capable of executing two experiments in space and transmitting data from Extreme Low Earth Orbit (ELEO), took off for space from Wallops Island in Virginia aboard an Antares rocket in the NG-15 Resupply Mission.

The mission of the Mason ThinSat payload, called ASTERIA, was to test a battery box with different types of thermal shielding and compare the relative effectiveness of two power-handling architectures. It will mean experimenting with using different power generation methods on a ThinSat.

“This means the world to me and is the highlight of my academic career!” said computer engineering graduate student Jay Deorukhkar. “Being able to participate in Mason’s very first satellite launch is a privilege beyond my imagination. The vision of Dr. Pachowicz and the hard work of everyone on the ThinSat team over the last two years is the reason we are here today. The successful launch will set Mason on a trajectory to many more launches and to further develop the satellite program.”

The two-semester senior design project included seven Mason electrical and computer engineering students, three mechanical engineering students and four from systems engineering. Their efforts served as a rousing kickoff to Mason’s Engineering Week festivities.

Deorukhkar, who was still an undergraduate when the project began in Fall 2018, was among the Mason students involved who have been able to gain practical engineering experience by designing and developing their own satellite payloads. The single-use Mason satellite launched from the rocket at 200 miles into the sky during the second of three planned staged rocket separations and will remain there for its five-day orbit lifetime while collecting data.

The Volgenau School of Engineering hosted a virtual party leading into the 12:36 p.m. launch.

ASTERIA is among 30 ThinSats aboard that were developed by university and grade-level STEM students to be launched into ELEO. Virginia Tech, George Washington and American Universities are among the other schools whose students developed ThinSats.

“Northrop Grumman is proud to help advance STEM education through the ThinSat program,” said Kurt Eberly, Northrop Grumman’s director of space launch and launch vehicles. “This program allows George Mason, George Washington and American University students to gain valuable engineering experience by developing satellites that will collect data in extreme low earth orbit.”

Roughly the size of a slice of bread, ThinSats reduce the cost and size constraints of traditional satellites while still providing the opportunity to explore outer space.

But creating your own comes with its own specific challenges.

“It’s not just having an idea,” said Pachowicz, an associate professor of electrical and computer engineering, “but it has to be finished at a high level that is acceptable to Northrop Grumman and it has to be tested in conditions the rocket would see such as vibration, vacuum, and temperature. Space is always challenging for engineers because of the environment and the many systems that you have to integrate into one unit. And when it launches, you can’t touch it, so you have to be very detail-oriented.”

The Virginia Space ThinSat program is comprised of a partnership between Northrop Grumman, Virginia Space, NASA Wallops Flight Facility, Twiggs Space Lab and NearSpace Launch, as well as university and grade-level schools across the country.

Northrop Grumman and NASA send supplies to astronauts on the International Space Station using the company’s Cygnus spacecraft, which launches from the Antares rocket. Northrop Grumman has named the Cygnus spacecraft for this mission after NASA mathematician Katherine Johnson, the African-American woman whose hand-written calculations were critical to America’s success during our first human spaceflight missions.

The Mason satellite project was developed in Spring 2019 and completed through in-house testing and modifications by Spring 2020, but the wait for an appropriate mission for its launch had been delayed by the global pandemic.

“We’re just happy it’s going to be launched,” Pachowicz said, “and we’re already looking forward to doing it again and to develop our own small-scale satellite platform which can be shared with others.”

Mason Engineering students and faculty compete at 99 Luftballoons competition

Mason Engineering students and faculty compete at 99 Luftballoons competition Anonymous (not verified) Fri, 01/08/2021 - 12:02

Left to right: Dinesh Karri, Robert Hooks, and Joseph Matthew Prince getting ready to compete at the Luftballoons competition at Indiana University.

It’s a bird, it’s a plane, it’s a Lighter-Than-Air (LTA) robotic shark blimp, which is what a team of ��AV students and faculty used to participate in the 99++ Luftballoons Competition at Indiana University on November 9 through 13.

The competition took place at the Indiana University Bloomington campus where people from Mason, the University of California Los Angeles, Indiana University at Bloomington, Pennsylvania State University, the Office of Naval Research, the Naval Surface Warfare Center – Crane Division, and the Army Research Laboratory competed in an aerial soccer match using remote-controlled LTA robots.

“LTA robots don’t need any support to hold them in the air. Helicopters need propellers, but all LTA robots can stay in the air on their own. Instead, they need controls to move them about in the air,” says Mason graduate student and competition teammate Joseph Prince Mathew.

Each team had defenders and seekers to protect their goal and score points against the other team. “It got pretty competitive,” says Dinesh Karri, another team member. “But it was so much fun.”

Every team played each other, and the teams with the most points faced off at the end of the five-day event. “Unfortunately, we lost, but we had the most points overall throughout the week,” says Mathew.

Mathew and Karri were working with Assistant Professor Feitian Zhang to develop an underwater glider as part of their PhD studies when they found out about the opportunity to bring their skills to the air. “It was a change of medium, from underwater to air. The dynamics are pretty similar,” says Mathew.

Robert Hooks, a junior undergraduate electrical engineering major, jumped on the project because of his interest in robotics and autonomous systems. “When I heard about it from one of my professors, I was very intrigued. It was a valuable and fun experience to learn hands-on,” says Hooks.
