Current and Recent Projects
Computational Aeroelasticity — In cooperation with researchers at NASA Dryden Flight Research Center, an effort is underway in predicting aeroelastic behavior of arbitrary aircraft configurations. Computational Fluid Dynamic (CFD) solutions are coupled together with structural motion equations in order to predict aeroelastic and aeroservoelastic effects over a wide range of Mach numbers from subsonic to hypersonic speeds. Of particular interest is the ability to predict aeroelastic flutter boundaries in a time-efficient manner on workstation computers in order to support flight-test operations.
Freeform Composites Design and Manufacturing — In cooperation with industry partners, a research effort is underway which involves the innovative use of Stereolithography equipment in manufacturing multifunctional composite parts.
Development of a New Wind Tunnel Facility — A new subsonic wind tunnel was recently designed and built for the Oklahoma State University School of Mechanical and Aerospace Engineering. The new facility will be used for research and undergraduate instruction. The tunnel design incorporates very low turbulence features, coupled with a high degree of flow uniformity. Test section flexibility is a primary design consideration to allow for a wide range of instrumentation to be used, and to allow fast turnaround time. The flow quality and optical access features designed into the tunnel allows for high quality flow visualization studies.
Unsteady Aerodynamics — The classical study of both Aerodynamics and Flight Dynamics makes the assumptions of a steady or quasi-steady flowfield, and a small disturbance theory. Aircraft or control surfaces undergoing large scale and/or rapid motions create flowfield characteristics which are not adequately modeled with these assumptions. Research involves development of computational methods for modeling unsteady flows and coupling the solution to the vehicle equations of motion. Complimentary experimental study provides insight into the proper modeling technique.
Limit Cycle Roll Oscillations of Slender Delta Wings — Aircraft with highly swept planforms may undergo a self-induced oscillation in roll known as "wing rock" when operating at large angles of attack. The motion poses safety concerns during the landing phase of future hypersonic transports, and limits the maneuverability envelope of several combat aircraft. Combined experimental and computational investigations of the wing rock phenomenon on slender delta wings have revealed key mechanisms responsible for the motion. Further research focuses on methods for controlling or exploiting the motion.
