Control system is one of the important aspects of aerospace industry products that allow aircraft to fly. One example is the Wright brothers, with their wing-warping system, which enabled the first practical aircraft to fly using the aerodynamic characteristics of the wing. Flight Control systems have been evolving ever since and produce modern control surfaces that are suitable for its mission. However, for high-speed missiles or fighter aircraft that need extreme maneuver, there is a limitation for using the control surfaces as the aerodynamic limitation of control surface effectiveness occurs at higher speed and angle of attack. In such cases, the thrust vector (TV) system is used as an alternative. This system directs and adjusts the magnitude of the thrust of the vehicle to control the trajectory, and has less constraint over aerodynamic limitation. In order to develop a TV system, an in-depth study is needed to help understand the phenomenon and characteristics of the system better This process will help in developing and finding the right method to apply TV systems in many aerospace products. Unfortunately, directly building one without prototyping or making a simulation to demonstrate whether the system will work will require a huge cost. Therefore, a demonstrator can become media to help understand better in this case. This work will cover a study to improve the demonstrator system which uses electric ducted fan (EDF) thrust vectoring control so it can be applied to aircraft that use a TV system. Data obtained from the demonstrator will be analyzed to understand the characteristics and performance by doing several test cases. Furthermore, a mathematical model with several assumptions will be derived and compared with the real one in this work. Based on design requirements, 4 out of 5 requirements are achieved. Further improvement in design especially nozzle design is needed to achieve the requirement.
