精品SM在线影片's Brian Argrow inducted into National Academy of Engineering for UAV severe storm research

The National Academy of Engineering is recognizing Brian Argrow as a

The distinction is one of the highest an engineer can receive in their career.

As a professor and chair of the Ann and H.J. Smead Department of Aerospace Engineering Sciences at the 精品SM在线影片, Argrow has conducted major research to advance uncrewed aerial systems to increase our understanding of supercell thunderstorms that can spawn tornados.

鈥淚t鈥檚 an honor, and it highlights our entire team. I鈥檓 just one person, but our work in uncrewed aerial systems is a team effort. It鈥檚 an interdisciplinary research area, with additional faculty here, professors at other universities and students. I鈥檓 getting credit, but there are a lot of contributors,鈥 Argrow said.

Argrow joined 精品SM在线影片 in 1992 and was originally focused primarily on computational fluid dynamics, particularly for potential hypersonic vehicles. It is still an ongoing area for his research, but at the time, the field was quite small and the aerospace department leadership was eager to have more research in applied aerodynamics, particularly autonomous systems or drones.

Because he had a personal interest in meteorology from a childhood growing up in rural Oklahoma, where tornadoes are a fact of life, Argrow saw potential to use drones to study storms. He decided to branch out into the subject.

To begin his work in the area, Argrow needed a drone. Although quad copters are now widely available, drones were far harder to come by in 1994. He got in touch with a professor at his alma mater, the University of Oklahoma.

Argrow knew OU researchers had built a small fixed-wing drone, and he hoped to join in the research they were doing. Instead, he learned the drone had flown only a handful of times before the project was abandoned.

鈥淲e were able to bring it to 精品SM在线影片 and tinkered around with it, but realized it wasn鈥檛 what we needed and we had to start from scratch,鈥 Argrow said. 鈥淭he culmination of that is we developed the capability of flying into supercells, which we continue to refine.鈥

The team鈥檚 work since then has been extraordinary.

They have developed multiple generations of UAVs and advanced the science of weather sensor technology. They also have special authorization from the Federal Aviation Administration to fly higher and in areas other small aircraft are not allowed to go.

Typically, the team spends part of each spring out in the field, traveling across the Great Plains pursuing supercell storms.

Their most recent field campaign, the TORUS Project, was conducted in 2019. Work in 2020 and 2021 was halted by the pandemic, but he is hopeful to be out again this year.

鈥淲e鈥檙e getting as many sensors onto a small aircraft as possible to maximize every flight we make into a storm. We want to increase the data to get at what is the recipe to making a tornado in order to develop better warning systems,鈥 Argrow said.

The data they capture will eventually be released publicly online so other scientists and engineers can study it. Although there are many researchers who are interested in analyzing tornadoes, none have the ability to collect field data from the air like Argrow鈥檚 team.

鈥淲e all stand on the shoulders of people who came before us. I didn鈥檛 invent calculus, Newton did. But I can use that knowledge,鈥 Argrow said. 鈥淭hese data can help everyone.鈥

With gigabytes of information already collected on supercell storms, Argrow is hoping to expand his research into a related area: hail. His engineering team is part of a larger science team pursuing National Science Foundation funding for a project called ICECHIP that would use existing drones to study storms that produce hail.

鈥淢any of those will also be supercells, not always. Like with our tornado work, it鈥檚 about learning the mechanism behind them. We want to develop more advanced warning, but if you know what forms them, maybe you can also prevent them,鈥 Argrow said. 鈥淭hat鈥檚 kind of pie in the sky. It鈥檚 a ways off, and perhaps I won鈥檛 be here for that, but someone will.鈥

Argrow will be officially inducted into the NAE during the organization鈥檚 annual meeting in Washington, D.C., on Oct. 2.
