BH660 TSD 250-400Hp Surface Drive Propellers For Sale/Hydraulic Propulsion System for Boats
The surface drive system places the propeller in a groove above the hull, which is designed to reduce contact between the water and the hull, thereby reducing drag. Propeller sizes for surface drive systems can be larger compared to conventional propeller designs because their axes can be steeper and propeller tip clearance is no longer a limiting factor. In addition, the Surface Drive system incorporates an adjustable lift system that allows the height of the propeller to be adjusted according to the boat's speed and water surface conditions. This allows the boat to maintain a more consistent speed and stability in varying water surface conditions, making it easier to maneuver the boat even in rough sea conditions. As a result, surface drive systems have been conceived to reduce drag and improve efficiency, while providing enough power and maneuverability to allow boats to travel at high speeds. It is an efficient, stable and easy-to-operate propulsion system.
Compared with conventional thrusters, TSD (Mobile Surface Drive System) has the following advantages:
Trimmability: The lift function of the TSD allows the propeller draft to be matched to the engine horsepower output so that more power is converted to generate thrust while the engine operates closer to its rated power curve. The propeller draft can be adjusted on the fly to achieve the optimum thrust angle for any load and sea condition.
Safety: All important components of TSD are located in the engine room, away from the harsh marine environment and protected from salt and water corrosion. All external parts that need to be in contact with seawater are made of stainless steel to minimize the harm of seawater corrosion and prolong the service life.
Efficiency: TSD's surface-perforated propeller design reduces underwater drag by 50%, compared to traditional underwater propeller drive systems, only the propeller blades and protective tail fins touch the water, resulting in increased overall speed, acceleration and payload-to-power ratio, reducing fuel consumption economy and operating costs.
To sum up, TSD has obvious advantages in trimmability, safety, and efficiency.
