Abstract

This paper proposes a combination of wind-tunnel tests and flight experiments to find an aerodynamic model of the Skywalker X8 airframe. This work is an extension of previous work that has been done at our lab. We apply a static transformation to the wind-tunnel data to increase its symmetry and improve the static model by reducing the test data and modifying the model structure. The static coefficients are then augmented with a parsimonious damping model that we find by using a sequentially thresholded least squares algorithm. Experimental results show significant improvements to the baseline model.
