The Simulation Of The Hovercraft’s Power System About The Fit Among Engine,Propeller And Lifting Fan

Hovercraft’s power system is different from common ship.It mainly reflects in using air-propeller as thruster and also equipping lifting fan when the common ships don’t have.In the side of transmission and control system,most of the hovercrafts on the home front are in the form of engine driving the air-propeller,lifting fan in series and using federated governance pattern.In addition,a part of hovercrafts run with separating propulsion system from air-cushion system.The engine-propeller and engine-fan control system are also separate.The simulation of hovercraft’s power system in the form of engine driving the air-propeller and lifting fan in series has already been studied for a lot at home,but there are few research about simulation of the hovercraft in the form of engine-propeller and engine-fan running independently.Different types of transmission mean engine-propeller-fan with different matching and control technique.Therefore,in order to know the performance of the hovercraft’s power system with different transmission patterns,also provide reference for designing the hovercraft’s control system,it is necessary to carry out the research of simulation on the hovercraft’s power system about the match among engine,propeller and lifting-fan.Taking a hovercraft’s power system as my objective,setting up the power system’s mathematical model,using the modular approach to simulating the power system,and setting up the simulation model based on MATLAB/SIMULINK,also analyzing and validating the simulation model.After simulating and analyzing how does the hovercraft’s power system work in the state of starting,loading and deloading,changing the pitch and one of the propulsion system malfunctioning.It can help set down the control strategy of power system.
