基于FlightGear的直升机可视化飞行仿真系统设计
Design of FlightGear-based helicopter visual flight simulation system
摘要
Abstract
Flight simulation is an essential process in the development of helicopter control system. On the VC 6. 0 platform, a nonlinear 6-DOF dynamic model of a helicopter along with flight control laws and remote control units are established and integrated together through the serial communication. The flight simulation data are transmitted to the FHghtGear simulator through UDP protocol using the external data input/output interface of FlightGear, and then drive the visualization engine of FlightGear to achieve the 3D visual display of weather conditions, flight attitude and geographical environment. The visual simulation system, which includes remote control units, flight control laws, helicopter dynamic model and visual simulation software, can directly and visually display the overall structure of the helicopter and its flight details. From the helicopter attitude, position and trajectory in the simulated flight, the defects of the helicopter control system can be found and therefore be helpful to the verification and the improvement of the control law design.关键词
