Abstract

Six degrees of freedom of the aircraft can be described by making a simulation using the MATLAB/Simulink 2021a software which is connected to FlightGear 2020.3 software for aircraft animation. The aircraft model is a twin engine civilian aircraft similar to the Boeing 757-200 made by the Group for Aeronautical Research and Technology (GARTEUR) in Europe whose longitudinal shape is non-linear while the lateral-directional is linear. This research is limited to the preparation of the aircraft motion model, entering the control surface that is carried out, namely the aileron, elevator, and rudder deflection. The motion response is described by using the input doublet on each control surface separately. Where the input is entered after the aircraft is in steady level flight at a certain speed. The simulation results show that the aircraft requires a more positive elevator deflection to be able to balance at higher speeds. With the elevator deflection input (longitudinal) it only affects the variables u (translational speed of objects on the x-axis), w (translational speed on the z-axis), q (rotational speed on the y-axis / pitch rate), and theta (euler angular position / pitch angle), while the others are 0 and stable. For input aileron and rudder deflection (directional lateral) affects the entire response, namely the variable v (translational speed of objects on the y-axis), p (aircraft rotational speed / roll rate), r (rotational speed on the z-axis / yaw rate), phi (position euler angle / roll angle), and psi (euler angle position / heading angle), as well as variables that affect longitudinal. So it can be stated that this plane shows stable dynamics.
