Design Modelling and Simulation of Tri-Tilt Rotor UAV

This aim of this paper is to present the design, modelling and simulation of Tri-Tilt Rotor(TTR) Unmanned Aerial Vehicle (UAV). The whole project was done in four different steps, such as design, analysis, modelling and simulation. In design phase, weight estimation was carried out to choose the suitable aerofoil and aircraft design parameters. In analysis phase, the complete UAV was designed in XFLR5 software and aerodynamic parameters were calculated. In modelling phase, the dynamics of the UAV were modelled in the form of forces and moments applied on the UAV and the PID controller were implemented in MATLAB. In simulation phase, the designed model was tested for altitude and attitude stabilisation and the simulation result shows that the desired altitude and attitude were achieved properly.
