Abstract: Current helicopter operation data cannot meet the needs of safety monitoring research. Based on C ++ and Simulink, a low-altitude helicopter flight data simulation system is established to simulate the key operational data such as flight control, avionics, and engines under different atmospheric wind environments. Simulation results show that the trimming data in the stable forward flight state has small deviation from the actual operational data. The system has high simulation accuracy. The proposed system can accurately simulate helicopter operational data under specific flight scenarios such as gusts, helping to solve the lack of helicopter safety monitoring data.
