This paper presents aerodynamic and mechanical design, prototyping and flight control system design of a new unmanned aerial vehicle SUAVI (Sabanci University Unmanned Aerial VehIcle). SUAVI is an electric powered quad tilt-wing UAV that is capable of vertical takeoff and landing (VTOL) like a helicopter and long duration horizontal flight like an airplane. Aerodynamic and mechanical designs ar...

In order to reduce the dependence on fossil fuels, concept of distributed electric propulsion (DEP) has been introduced. At present, there are a few studies small engines DEP vertical take-off and landing (VTOL) UAVs. According design requirements VTOL UAV ducted fans, aerodynamic fan is carried out in this paper. Firstly, initial model established by referring theoretical derivations. Then, Be...

Extended Abstract The emerging area of intelligent unmanned aerial vehicle (UAV) research has shown rapid development in recent years and offers a great number of research challenges for artificial intelligence and knowledge representation. Much previous research has focused on low-level control capability with the goal of developing controllers which support the autonomous flight of a UAV from...

This study aims to produce a Fixed Wing-Vertical Takeoff Landing (FW-VTOL) design that has good aerodynamic characteristics on its wing and fuselage. The process begins with determining the Design Requirement Objective (DRO). According DRO, aircraft is designed be able operate at speeds of 14 m/s an altitude 120 m (cruise phase) above ground level. Maximum Weight (MTOW) planned estimated using ...

A lot of UAV applications require vertical take-off and landing (VTOL) combined with very long-range or endurance. Transitioning UAVs have been proposed to combine the VTOL capabilities helicopters efficient flight properties fixed-wing aircraft. But energy is still a bottleneck for many electric long endurance applications. While solar power technology battery improved lot, in rougher conditio...

This study presents a control design of roll motion for vertical take-off and landing unmanned air vehicle (VTOL-UAV) based on the Model Reference Adaptive Control (MRAC) scheme in hovering flight phase. The adaptive laws are developed UAV system under nonparametric uncertainty (gust wind disturbance). Lyapunov-based stability analysis controlled has been conducted have accordingly developed. U...
