Özet:

Aerodynamic characteristics of missiles depend strongly on wind angles, that is, angle of attack and sideslip angle. However it is impractical to measure these angles during missile testing. Therefore, without direct information of the wind angles, it becomes a difficult problem to be able to accurately estimate the missile aerodynamic parameters from flight tests. This thesis addresses this problem and suggests an approach to estimate missile aerodynamic parameters successfully without wind angles measurements. Instead of reconstructing wind angles with post-process calculations prior to estimation, reconstruction process is handled within the estimation. The algorithm developed is tested with simulated missile data. Results are compared with true values used in simulation. It is demonstrated that suggested approach can provide accurate and reliable estimations without wind angles measurements. The approach is also applied to real flight test data of a missile with success.
