Fault Simulation of a Helicopter Hydraulic System Based on SimHydraulics

A single booster simulation model of a helicopter hydraulic system was constructed by using SimHydraulics.By setting the parameters of the hydraulic components in the model,the effects of the movement and response characteristics of the actuator on the helicopter flight control under different fault states were simulated.The simulation results show that the constructed model can better reflect the working status of the helicopter hydraulic control system.Through the fault simulation,the pilots can intuitively recognize the impact of different hydraulic system faults on the helicopter flight control,which is helpful to improve pilots’emergency handling ability of hydraulic system faults.
