<\/a>Haibo Dong, Ph.D., assistant professor of mechanical and materials engineering, is only the third Wright State faculty member to receive the NSF\u2019s Faculty Early Career Development (CAREER) Award.<\/p><\/div>\n
A Wright State University scientist\u2019s quest to learn nature\u2019s most mysterious secrets of flight has earned him a prestigious National Science Foundation award.<\/p>\n
The NSF\u2019s Faculty Early Career Development (CAREER) Award will provide $400,004.00 over five years for Haibo Dong, Ph.D., assistant professor of mechanical and materials engineering, to advance the knowledge of biological fluid dynamics in free-flying animals.<\/p>\n
The groundbreaking work has potential application in the development of insect-size aircraft for the military, but it\u2019s also aimed at making tools used in advanced engineering studies more accessible to biologists and other researchers for education and research.<\/p>\n
The NSF describes the CAREER awards as among its most prestigious. It awards them to boost the careers of junior faculty who combine excellent research with teaching.<\/p>\n
Dong is only the third Wright State faculty member to receive the award, according to Jack A. Bantle, Ph.D., vice president of research and graduate studies.<\/p>\n

To date, much of his funding has come from the Air Force, which is striving to develop bird- and insect-size micro air vehicles for dangerous or sensitive missions.<\/p>\n Research like Dong\u2019s is important because the aerodynamics of big, fast airplanes don\u2019t work for very small wings and low speeds. \u201cIf you scaled a Boeing 737 down to this size it would not easily fly,\u201d Dong said.<\/p>\n What has set Dong\u2019s work apart is the ability to capture the wing flapping of freely flying animals, especially insects such as dragonflies and damselflies. Previous research typically tethered insects by gluing them to sticks or tying them by strings, he said.<\/p>\n Click here to watch a video from the laboratory showing how dragonflies fly<\/a><\/p>\n Click here to watch an animation of the flight of a dragonfly<\/a><\/p>\n \u201cBut this would change their behavior. And what they are doing is actually trying to get rid of the restraint,\u201d he said.<\/p>\n His students have come up with various methods to coax the insects to fly. \u201cIt\u2019s difficult, but still, it\u2019s doable,\u201d he said. The proof is a collection of nearly 500 video clips of insects taking off, hovering, turning and cruising, he said.<\/p>\n Three high-speed cameras mounted at right angles and focused on a small zone capture the flying motions. A laser triggers the cameras when an insect moves within the zone. The insects\u2019 wings are dotted with grid patterns, which allow computer programs to convert their motions into 3D animations.<\/p>\n These techniques already have revealed new knowledge about how insects\u2019 wings work. For example, Dong said, the research has shown that Dragonfly wings don\u2019t move like stiff plates as most research work assumed, but flex significantly as they flap.<\/p>\n Computer modeling and simulation technology creates visual representations of the air currents, or vortices, the flapping generates. It has revealed that each type of small bird and insect creates distinctly different vortex patterns. The CAREER grant will allow Dong\u2019s group to do comparative studies aimed at finding out why they differ, whether one is the most efficient, and ultimately advance the development of a comprehensive theory of aerodynamics for small flying creatures.<\/p>\n Beyond the research itself, Dong\u2019s project will help make the advanced engineering tools his group uses, including some of its own design, available to biologists and other researchers worldwide for education and research.<\/p>\n Dong\u2019s work has drawn interest from engineers and biologists around the world. He said his CAREER grant proposal drew 21 letters of support from across the United States and abroad. The results of his research have been published internationally in professional journals and the press, including a Discover magazine article in 2010.<\/p>\n Dong earned his Ph.D. at UCLA in 2002 and came to Wright State in 2006. He received a university Faculty Award for Excellence in 2010. The award noted he had secured more than $500,000 in outside funding for research and was the only faculty member in 2010 in this area to receive two awards under the Air Force Research Laboratory-Dayton Area Graduate Studies Institute student-faculty fellowship program.<\/p>\n The CAREER award also shows Wright State is a good place to advance a research career, Dong said. \u201cPeople outside are talking more and more about the good work from Wright State. We are educating people and doing very high quality research.\u201d<\/p>\n For his own work, Dong said Ohio is a great place to study insect flight. The state of Ohio and Wright State University have given strong support to his research, Dong said. And, in Ohio\u2019s warm summer months, \u201cWe can easily find tons of dragonflies in the parking lot.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":" A Wright State University scientist\u2019s quest to learn nature\u2019s most mysterious secrets of flight… Continue reading ![\"Photo](\"http:\/\/webapp2.wright.edu\/web1\/newsroom\/files\/2011\/06\/Dong-insect-235x300.jpg\")
