21；The hydraulic jet propulsion system 21 and propeller plant 11 collectively constitute steering system.
Oscillating oil cylinder 32, propeller pushing meanss 11 and hydraulic jet propulsion system 21 are controlled by signaling module and are driven.
The working principle of the trimaran structure with hydrofoil is:
When normal/cruise, the hydraulic jet propulsion system of lateral body to be opened is considered whether depending on concrete condition.It is only needed when lowsteaming
The propulsion device for opening main hull, the propulsion system that can star lateral body when needing high speed operation improves the speed of a ship or plane, if still needing
The speed of a ship or plane is further increased, controllable oscillating oil cylinder puts down hydrofoil；When needing to turn to during navigation, two sides need to be only controlled
The propulsion device generation propulsive efficiency of body is poor, can realize the efficient controllable steering to hull.
Put down hydrofoil process: oscillating oil cylinder obtains after putting down the order of hydrofoil, and oscillating oil cylinder starting drives driving lever to start
Rotation, follower lever move therewith, and hydrofoil remains horizontal in the whole process, go deep into water surface following certain depth to hydrofoil,
Oscillating oil cylinder stops working, and puts down the completion of hydrofoil process；Two hydrofoils are all made of the structure of wing type profile, pass through control system
Instruction, pack up hydrofoil when realizing hull lowsteaming, reduce ship resistance, hydrofoil is unfolded in when high speed operation, and lifting hull subtracts
The function of few water resistance.
Progradation: the propeller plant of main hull first starts to start, when needing high speed operation, subsequent start-up
The hydraulic jet propulsion system of two auxiliary hulls, ship's speed is promoted very fast at this time, when the speed of a ship or plane reaches a timing, releasable two hydrofoils,
Make hydrofoil submerged in water, hydrofoil starts generation effect under fast state, hull is carried away the water surface, since hull and water connect
Contacting surface product is reduced, and is considerably reduced the viscosity resistance of ship, is further increased propulsive efficiency.
Steering procedure: when normal/cruise, decide whether to open lateral body hydraulic jet propulsion system depending on ship's speed situation.When ship is navigating
When needing to turn in row, change the injection differential of two sides hydraulic propeller by control system, to generate along hull longitudinal direction
Steering moment is directly realized by the control to hull steering angle, is reached not by the size of accurate, effective control injection differential
