The interference model design of aircraft in the wind

摘要

Wind is one of the key factors affecting flight. In order to accurately calculate the aircraft parameters under wind environment, to study the establishment methods of the wind field model. First, the analysis of their mathematical model to establish the theoretical framework of the model wind. Then, study the relevant parts of the aircraft, its analysis of wind effects on the flight path. Then, modeling in the Simulink environment and using C MEX S-function for programming for complex equations of flight mechanics. Finally, packaging the sub-module based on the unified interface and connecting sub-models to establish the overall model. By a certain type of aircraft to wind disturbance simulation, we can prove the model stability, minimum calculation step up to 1ms and can accurately simulate the wind field Which can calculate the wind conditions aircraft parameters. The results show that the program reasonable and reliable to meet the engineering requirements.
