Design and Implementation of a New Training Flight Simulator System

Abstract

Aircraft flight simulators have good cost efficiency, high reusability, and high flight safety. All airlines and aircraft manufacturing companies choose it as sophisticated training equipment for ground simulation, effectively reducing pilot training costs, ensuring personnel safety and aircraft wear and tear. The new simulator proposed in this paper combines a digital motion-cueing algorithm, flight software and motion platform to make pilots feel as if they are in the real world. By using EtherCAT technology to drive the motion-cueing platform, it can improve the data transmission speed of the simulator as well as the strong anti-interference ability of communication and the control operation efficiency. Therefore, the simulated flight subjects can perform long-distance and large-angle training. Next, a set of measurement systems was established to provide monitoring items including attitude, velocity and acceleration, which can be displayed on the screen and recorded on the computer in real time and dynamically. Finally, seven training subjects were implemented to demonstrate the feasibility and correctness of the proposed method.

“…The 2T2R manipulator organically combines spatial translation and rotation, and is widely used in industry. For example, this manipulator can be combined with linear guide rail to form a five-axis linkage CNC machine tool [6, 7] and can also be used as motion simulator [8], vibration isolation platform [9], and so on. Among which, CNC machine tools have requirements for high accuracy of the manipulator, while the others have certain requirements for high-frequency and high-acceleration characteristics.…”
