Research on Helicopter Flight Simulation Method based on Component-level Modeling
Flight simulation models are essential components of flight simulation devices.This the-sis introduced a helicopter flight simulation method based on component-level modeling.The model was developed on the MATLAB/Simulink platform,which was suitable for real-time simulation of helicopter flight aerodynamic characteristics.The component-level modeling architecture of the model and methods for parameter adjustment were introduced in the text.With the specified object for simulation,the adjustable parameter ranges within certain modules were presented.Taking the issue of ground-based automatic takeoff task during the system joint debugging process as an exam-ple,this experiment elucidated the impact of parameter adjustments on system applicability and sub-stantiates the effectiveness of the model.
