Error analysis and motion determination of a flight simulator

Abstract

A flight simulator must be designed to generate the correct acceleration cues, attitudes and vibrations to the flight compartment to provide an extra degree of realism for the pilots. Therefore, such a system, which has six degrees of freedom (dof), should enable to produce pitch, roll, yaw, heave, forward and lateral movement simultaneously. However, such a complex dynamic system can be modeled as a Stewart platform with pneumatic actuators, having six dof. During the simulations, on the position and orientation of moving platform, motion determination parameters and their absolute, relative errors and standard deviations are outlined. Simulation results, which are obtained, when closely examined reveal that the developed motion determination algorithm for the considered parallel dynamic mechanism is highly accurate. Additionally, a technique is introduced for the motion determination and its deviation from the given task.

“…The corresponding hydrodynamic coefficients can be obtained by linear fitting and combining the hydrodynamic model parameters in Table 6 into Eq. (24). The hydrodynamic coefficients obtained by the dimensionless treatment are summarised in Table 9.…”

“…The spherical hinge is supported on three driving legs with adjustable lengths and angles, and connected to the ground through two axle joints. Yurt designed a Stewart platform with six degrees of freedom and a pneumatic actuator for a flight simulator by using the method of complex dynamic system modelling [24]. Landry designed and implemented a low-cost flight simulator using commercial components for the Royal Military Academy of Canada [25].…”
