| Outline of Final Research Achievements |
For the purpose of improving the thrust, maneuverability and mobility, research to develop stabilizer-less (stabi-less) unmanned helicopters were carried out. We constructed a horizontal motion model including the flap angular motion of the rotor blade and the stabilizer, and clarified the role of the stabilizer in flight dynamics. It was revealed that the non-uniform distribution of the induced velocity has a large influence on the coupling response. We proposed a method of constructing flight control system by dynamic inversion method including control of rotor blade flap angle. By numerical simulation and flight experiments, we were able to transcend both stability, maneuverability and motility compared with the aircraft equipped with stabilizers. As the results, stabi-less unmanned helicopters became much more stable, operable and motile compared to unmanned helicopters with stabilizers.
