Experimental Determination of Dynamic Derivatives in a Wind Tunnel Using Parameter Identification

For the experimental determination of dynamic derivatives a new method is presented. Instead of sinusoidal oscillations the models undergoes specifically designed maneuvers on the wind tunnel’s 6 DOF model support. For data evaluation the parameter identification method, as used in flight testing, is employed. The main advantages over the classic approach are significantly reduced testing time and suitability for nonlinear aerodynamic models
