    Design and Control of a Gas-Electric Hybrid Quad TiltRotor UAV with Morphing Wing
    (Ieee, 2015) Çetinsoy, Ertuğrul
    In this work, design and control system development of a gas-electric hybrid quad tilt-rotor UAV with morphing wing are presented. The proposed aircraft has an all carbon-composite body, gas-electric hybrid electric generation system for 3 hours hovering or up to 10 hours of horizontal flight, a novel configuration for VTOL and airplane-like flights with minimized aerodynamic costs and mechanical morphing wings for both low speed and high speed horizontal flights. The mechanical design of the vehicle is performed to achieve a strong and light-weight structure, whereas the aerodynamic and propulsion system designs are aimed for accomplishing both fixed wing and rotary wing aircraft flights with maximized flight endurance. A detailed dynamic model of the aerial vehicle is developed including the effects of tilting rotors, variable fuel weight, and morphing wing lift-drag forces and pitching moments. Control system is designed for both flight regimes and flight simulations are carried out to check the performance of the proposed control system.

    Design and flight tests of a holonomic quadrotor UAV with sub-rotor control surfaces
    (2013) Çetinsoy, Ertuğrul
    In this work, a quadrotor helicopter UAV with sub-rotor control surfaces for non-inclined horizontal motion is designed. Dynamic model of the air vehicle and an eight output PID control system is designed for controlling both the rotor speeds and control surface angles. The performance of this control system on the air vehicle is presented through simulation results with severe wind conditions and initial flight test results acquired from the prototype. © 2013 IEEE.

    Design and simulation of a holonomic quadrotor UAV with sub-rotor control surfaces
    (2012) Çetinsoy, Ertuğrul
    In this work, a quadrotor helicopter UAV with sub-rotor control surfaces for non-inclined horizontal motion is designed. Dynamic model of the air vehicle is developed including the control surface driven drag and pushing forces, and the relevant moments. An eight output PID control system is designed for controlling both the rotor speeds and control surface angles. The performance of this control system on the air vehicle is presented through simulation results with severe wind conditions. © 2012 IEEE.

    Design of an ex-proof untethered in-pipe inspection robot
    (Institute of Electrical and Electronics Engineers Inc., 2018) Çetinsoy, Ertuğrul; Esgin, Hakan
    In this work, the design of a natural gas pipeline inspection robot that generates energy from gas flow, performs onboard image processing and handles propulsion through biometal fiber (BMF) driven arms is presented. For an in-pipe inspection of an explosive gas filled pipe to be performed properly in real operational conditions, the robot should be free of external cable to prevent gas leakage from the pipe, ex-proof to prevent any spark that can lead to a fire or explosion, and adaptive to highly varying pipe diameters and tight curvatures on L and T joints. Novel solutions that address the mentioned requirements are proposed for systems of propulsion, energy source, data acquisition and communication. Design of robot that combines all these solutions is explained in detail. © 2018 IEEE.
