Dr. Gopalarathnam directs the NCSU Applied Aerodynamics Group. Dr. Gopalarathnam (referred to by his students as Dr. G) is committed to the development of innovative and useful ideas, concepts, and methodologies for the design of aircraft, other types of vehicles, and for alternative-energy systems. He is interested in applied aerodynamics, flight mechanics, aircraft design, adaptive aircraft, and design methodologies.

At the graduate level, Dr. G teaches Airfoil Theory (MAE 551) and Wing Theory (MAE 561). In these courses, the students look beyond theoretical methods in aerodynamics and address practical requirements in the design of airfoils and wings. At the undergraduate level, Dr. G teaches Aerodynamics of V/STOL vehicles (MAE 452) and Flight Vehicle Stability and Control (MAE 462). In MAE 462, his students do team projects in which they design/build/fly micro-gliders.

The graduate students who work with Dr. G are motivated and have an interest in flight and aerodynamics. During their studies, they are exposed to a mixture of theoretical, experimental, and computational methods applied to the design of a wide range of aero-hydrodynamic systems. His students work on sail boats, race cars, aircraft, and wind turbines, to name a few.

Outside of work, Dr. G spends time with his family and enjoys recreational flying when time permits.

Research Description

Dr. Gopalarathnam is presently 1) developing adaptive aerodynamics for morphing aircraft, 2) developing aerodynamic prediction techniques for flight dynamics simulations, and 3) studying unsteady and post-stall aerodynamics of aircraft, helicopters, micro-aerial vehicles, and flight in nature. In MAE, Dr. G works with Dr. Edwards, Dr. Wu, and Dr. Peters.
