The aerodynamic design and analysis of an Unmanned Air Vehicle, capable of vertical take-off and landing by employing fixed four rotors on the tilt-wing and two rotors on the tilt-tail, will be presented in this study. Both main wing and the horizontal tail can be tilted 90 degrees. During VTOL, transition and forward flight, aerodynamic and thrust forces have been employed. Different flight conditions, including the effects of angle of attack, side slip, wing tilt angle and control surfaces deflection angle changes, have been studied with CFD analysis. For a Tilt-Wing UAV, there are challenges like high non-linearity, vulnerability to disturbances during hover and transition, cross-coupling between three axes, very low time to double amplitude of the open-loop system. Therefore, the aerodynamic analysis has been done in detail considering especially the challenges in transition phase of the flight envelope.

Design and analysis of a VTOL Tilt-Wing UAV
Çakır, Hasan; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2020)
In this study, the design and analysis of a UAV, which is capable of vertical take-off and landing using fixed six rotors placed on the tilt-wing and tilt-tail, will be explained. The aircraft has four rotors on its wing and two rotors on its tail. The main wing and horizontal tail are capable of 90° tilting. Both aerodynamic and thrust forces are used during VTOL, transition, and forward flight. Aerodynamic analysis has been performed in ANSYS Fluent v.18. A non-linear six DoF model, involving a 3D CAD mod...
Hovering Control of a Tilt-Wing UAV
Çakır, Hasan; Kurtuluş, Dilek Funda (2019-09-20)
In this study, the design and analysis of hovering controller of an UAV which is capable of doing vertical take-off and landing using the fixed six rotors placed on the tilt-wing and tilt-tail will be explained. The aircraft will have four rotors on the wing and two rotors on the tail. The main wing and horizontal tail will be capable of 90° tilting. Whole flight is separated into three flight modes, which are VTOL, Transition and Forward Flight, to have a robust control on aircraft. Only hover control of t...
Design and analysis of a mode-switching micro unmanned aerial vehicle
Cakici, Ferit; Leblebicioğlu, Mehmet Kemal (SAGE Publications, 2016-12-01)
In this study, design and analysis of a mode-switching vertical take-off and landing (VTOL) unmanned aerial vehicle (UAV) with level flight capability is considered. The design of the platform includes both multirotor and fixed-wing (FW) conventional airplane structures; therefore named as VTOL-FW. The aircraft is modeled using aerodynamical principles including post-stall conditions. Trim conditions are obtained by solving constrained optimization problems. Linear analysis techniques are utilized for trim ...
Design, modeling and control of a hybrid UAV
Muratoğlu, Abdurrahim; Tekinalp, Ozan; Department of Aerospace Engineering (2019)
Vertical takeoff and landing (VTOL) vehicles that can fly like conventional airplanes after the takeoff, provide a promising area to find applications in the future. These hybrid vehicles combine the advantages of rotary-wing and fixed-wing aircraft configurations such as having capability of hovering flight, takeoff and landing without utilizing a runway, long range, high speed flight with reasonable endurance. In this study, a tilt-rotor tricopter VTOL UAV having a conventional fixed-wing airframe is desi...
Designing autopilot and guidance algorithms to control translational and rotational dynamics of a fixed wing VTOL UAV
Güçlü, Anı; Kurtuluş, Dilek Funda; Department of Aerospace Engineering (2020)
Guidance and autopilot algorithms are designed and applied to a fixed wing VTOL air vehicle. The algorithms are developed on a rotary wing and a fixed air vehicle. Each air vehicle is identified by experimentation to reduce the discrepancies among the system model and the actual air vehicles. Designed controllers for the air vehicles are deployed to Pixhawk Cube controller board. Indoor and outdoor flight tests are carried out. For the rotary wing air vehicle, active disturbance rejection control algorithms...
