Sažetak
In the summer of 2019 the Center for Aviation at the Zürich University of Applied Sciences conducted a flight test campaign on a Piper Pa-28-161 airplane. Since then, they have the goal of a self-made model of a Piper PA-28 which can be implemented in their Research and Didactics Simulator. This thesis is concerned with all the necessary data gathering and set up for a parameter estimation process determining aerodynamic coefficient models. Along with the basic introduction to the system identification and parameter estimation, this thesis provides an overview of the flight test data, instrumentation and test points together with some challenges and issues that have to be mentioned before the data can be used. After the processing procedure of the flight test data, it is shown how the estimation of the mass, balance and inertia of the aircraft is performed. Next, engine forces and moments needed for aerodynamic coefficient calculation are computed. Additional data corrections and sensor error model development with flight path reconstruction is presented as well. Finally, after all the data is gathered and assembled, parameter estimation with linear estimation is done using the ordinary least squares method. Exemplary models of the aerodynamic coefficients are offered as well.
