In order to develop and demonstrate a systematic approach to assessing and modeling dynamic characteristics for advanced configurations, a comprehensive dynamic wind tunnel test program was conducted for the F-16 and the F-22 at the 12-ft Vertical Wind Tunnel at WPAFB. Using the recently-developed Multi-Axis Test rig, body-axis forced oscillation, velocityvector steady rotation, and the new com...

In order to upsurge the maneuverability of micro aerial vehicles, a tubercle leading edge inspired by whale flipper was applied as passive stall control method. Although this method could be useful phenomena, effect geometrical properties on flow physic should investigated reach root them. According preceding research, some parameters wing is hot topic among researchers. The aim research explor...

Birds have the impressive ability to gracefully ‘swim’ through the air while executing aerobatic maneuvers that routinely defy modern aeronautical and control engineering, consistently reminding us that the skies are truly their playground. Many of these animals are masters at exploiting post-stall pressure drag to execute maneuvers with unprecedented speed and precision, with nowhere near the ...

An iterative decambering approach for the post stall prediction of wings using known section data as inputs is presented. The method can currently be used for incompressible flow and can be extended to compressible subsonic flow using Mach number correction schemes. A detailed discussion of past work on this topic is presented first. Next, an overview of the decambering approach is presented an...

Optimizing the NACA0015 airfoil which is widely applied in small-scale vertical axis wind turbine to make it has a better aerodynamic performance. In the optimization process, using CST parameterization method to perturb the airfoil geometry, the thickness and camber of the airfoil are selected as the constraint, and the value of the maximum tangential force coefficient is chosen as the objecti...
