Abstract

This study examines the change in the longitudinal and lateral stability parameters of fixed-wing unmanned aerial vehicles (UAVs) according to changes in wing sweep and dihedral angles. Unlike studies in the literature that focus on changes in wing sweep and dihedral at a single point, no study has been found that examines UAVs with wing sweep and dihedral angles at two different points on the wing. In this study, both dihedral and sweep angles were applied at two different positions on the wing, and models were created accordingly. Numerical analyses examining 16 different cases simultaneously, with initial conditions set at 5°,15° sweep and 5°,15° dihedral angles, resulted in the determination of the damping ratios and natural frequencies of the lateral and longitudinal stability modes. The variation of these parameters with respect to changes in double dihedral (DD) and double sweep (DS) angles was observed.
