Design and integration of full flight stabilized spherical simulator

Nowadays, with the development of technology, the usage areas of simulators are increasing and diversifying. As simulators can find a place in every sector, they also play a major role in aviation and space studies. Flight simulators are devices that artificially recreate the flight of the aircraft and the environment in which it flies. External effects such as flight systems and turbulence are among the elements that can be simulated by flight simulators, taking into account the dynamics of the aircraft during the modelling of the aircraft. Although aircraft design and research and development studies are among the purposes of flight simulators, the widespread use of flight simulators is pilot training. Since flight training is risky and costly in terms of safety, flight simulators are frequently used in pilot training. In addition, the use of flight simulators is a safe and cost-effective solution for the study of certain scenarios such as engine failure and difficult weather conditions, which are difficult or impossible to implement in real life. The main purpose of simulators is to make the user feel the flight scenarios created in the computer environment in a realistic way. In this study, a new spherical flight simulator was designed and manufactured, and the nonlinear dynamics of the spherical flight simulator was modelled mathematically using the Newton-Euler method. The obtained mathematical model is used in the controller design for the spherical flight simulator. In the controller design, pole placement method and linear quadratic regulator method (LQR) are selected and these methods are compared. The mathematical simulation of the system was performed in SIMULINK environment.
