Evaluation of an Aerodynamically Driven Model Mount for Dynamic Wind Tunnel Testing 965629
A series of aerodynamically driven model mounts for dynamic wind tunnel testing were designed, built and evaluated at Wichita State University. The mount proved to be very responsive, stable and capable of generating a wide variety of pitching motions. However, the response of an early variant of this mechanism displayed “stair-step” like behavior during slow pitching motions and damped oscillations at the end of rapid pitching motions. Numerical and experimental evaluations demonstrated that these undesired characteristics are minimized when the size of the control surface is increased and the inertia of the apparatus is reduced. In addition, this novel mechanism was utilized to demonstrate the type of valuable data that can be obtained. Force data for an oscillating NACA 0012 wing section is provided.
