All Kinds Marine Copper Alloy Propeller For Ship
From the process of designing, manufacturing, mooring trial, sea trial and delivery of the propulsion system, we have accumulated rich experience in the scope of the propulsion system's integration.
Types of marine propellers
Controllable-pitch propeller
One type of marine propeller is the controllable-pitch propeller. This propeller has several advantages with ships. These advantages include: the least drag depending on the speed used, the ability to move the sea vessel backwards, and the ability to use the "vane"-stance, which gives the least water resistance when not using the propeller (e.g. when the sails are used instead).
Skewback propeller
An advanced type of propeller used on German Type 212 submarines is called a skewback propeller. As in the scimitar blades used on some aircraft, the blade tips of a skewback propeller are swept back against the direction of rotation. In addition, the blades are tilted rearward along the longitudinal axis, giving the propeller an overall cup-shaped appearance. This design preserves thrust efficiency while reducing cavitation, and thus makes for a quiet, stealthy design.
A small number of ships use propellers with winglets similar to those on some airplanes, reducing tip vortices and improving efficiency.
Modular propeller
A modular propeller provides more control over the boat's performance. There is no need to change an entire prop, when there is an opportunity to only change the pitch or the damaged blades. Being able to adjust pitch will allow for boaters to have better performance while in different altitudes, water sports, and/or cruising.
