What are surface drives, and how do surface drives work?The surface drive are working near the water surface,with the blade part time in the water and the other part time spining in the air.The propulsion device located above the water surface, in addition to the drive shaft system containing the propeller, also has a mechanism for adjusting the pitch and heel angle of the shaft system.Adjust the propeller shaft to match the sailing state by adjusting the propeller shaft immersion depth.By adjusting the heel angle to achieve the effect of vector thrust, it can control the course of the boat more powerfully than the rudder propeller.Having the propeller at the surface level reduces drag and reduces the vessels draft, making the surface drive suitable for many applications where the owner is looking to reduce fuel costs, increase speed and create a more efficient vessel.
It has the characteristics of no cavitation and denudation, low resistance, shallow draft and high efficiency when sailing at high speeds. It is the preferred propulsion method for new high-speed ships in the world today.
The TSD series surface drive propeller is a high-tech Chinese-made propulsion device designed and launched by TF for high-performance boat propellers. The device adjusts the immersion depth of the propeller through a hydraulic cylinder to make it run near the water surface, which has lower resistance and higher efficiency than conventional propeller attachments. The professional scheme design makes the boat equipped with the device better match the propeller performance, and the efficient vector propulsion makes the boat more stable, faster and more flexible in actual control.
TSD series surface drive propulsion device, TF company has completely independent intellectual property rights, can carry out ccs product certification according to customer requirements, and provide full-cycle technical services from boat design to use and maintenance. This series of devices is suitable for steel, aluminum, composite materials and other hulls ranging from 7 meters to 35 meters, and has been successfully applied to various military ships, official ships, tourist ships and hydrographic ships.
