Semi-Submerged Propeller (SSP) means that placing 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.
The surface drive propulsion system (also known as semi-submerged propeller) independently developed by Tofoo Electronics Engineering Co., Ltd. for TSD type high-speed boats has been tested in Changsha, China, with a maximum measured speed of 78.9 km/h, which has been successfully used in high-speed boats. This technology has obtained a number of utility model patents and invention patents. The success of this test voyage fully demonstrated the maturity of the key technology and core technology of the high-speed surface propeller device, marking that the surface propeller device and surface propeller technology for domestic TSD high-speed boats have gradually matured, and the application direction of the product will be more mature. It is safe, efficient and cost-effective.
Design Advantage
A pair of TDS surface drive can lift and steer system
A pair of high anti-corrosion, high toughness and strength two-way special stainless steel surface perforated propellers
Hydraulic and steering equipment
The body i s made of all 316L anticorrosive stainless steel
Indicators and sensors
Double hydraulic cylinder
Two kinds of adjustable movable and fixed semi-submerged propeller systems
Universal ball cage connection design
Performance Advantages
The water intake of the surface piercing propeller i s half of the water intake
15% to 30% faster than traditional systems
15% to 30% increase in fuel efficiency
The propeller i s ventilated to the water surface, thereby reducing noise and destructive hull and pillar erosion.
The maintenance requirements are low, and the propeller immersion can be adjusted in progress.
