Research on Underwater Vector Propulsion Device Imitating Helicopter Rotor
Based on the vector propulsion technology of helicopter,an underwater propulsion device is developed to improve the flexibility of the carrier and reduce the operation difficulty of the carrier,and the initial test is carried out on the ship model.Considering the similarity between the atmosphere and the underwater environment,the metal head rotor assembly device of the model is applied to the ship model to replace the original underwater propeller of the ship model.The three degrees of freedom of the control motion direction of the rotor head assembly device are controlled by a bus steering gear,and the rotation of the rotor spindle is driven by 38 motors through belt drive.Since the rotor head assembly device is located underwater,and the bus steering gear and the 38 motor need to be on the water surface,the movement between them is connected by a set of transmission devices,so that the control system on the water surface can control the movement of the rotor head assembly device under the water surface.The transmission device is modeled by three-dimensional software and 3D printed out.Based on the understanding of the vector propulsion technology of the helicopter,the vector propulsion of the vehicle is simulated on the basis of this technology,and the latest underwater propulsion device is manufactured to improve the flexibility and safety of the vehicle and reduce the accident trigger rate of the ship.It can not only be applied to small water yachts,large can be used for ten thousand tons of ship,even in the future when the technology is mature,can also be used for the navy's submarines,is a valuable and promising project.
