A propeller consisting of a hub and a plurality of blades fixed radially to the hub, commonly known as a vane. The propeller is installed below the stern waterline, and the host receives power to rotate, pushing the water toward the ship, and pushing the ship forward by the reaction force of the

[Popular Science] Damage of Cavitation to Ship Propellers Few people associate small bubbles with lethality. But in fact, those bubbles are extremely lethal for poorly designed propellers.Propellers are generally one of the hardest parts on a ship, but they are often killed by bubbles. And here th

Accurate inflatable boat propeller pitch is significantly dependent on the size, weight and type of the ship, as well as the power of the engine. Please note that adjusting the pitch and diameter of your inflatable boat propeller is important for its speed and performance on the water. If you ar

The Flishpropeller series of products are produced through a process that is strictly prohibited. Whether it is material selection, overall geometric design, product testing and production, it is to enhance the performance of the propeller, better adapt to navigation conditions and make full use of

For nearly a hundred years, the role of the propeller has never been lacking, but rather a lot of "deformation". In addition to the common styles, different types of marine propellers also include variable pitch propellers, counterpropellers, guide vanes, pod propellers, water jet propellers, etc.,

At present, the mainstream spiral slurry of marine vessels is made of copper-nickel alloy or copper-manganese alloy. Of course, there are stainless steel, cast iron, and even fiberglass reinforced plastic propellers, but the number is small.Let's see how the copper-nickel alloy propeller is process

What is the principle of marine propeller actuation? We can explain from two different perspectives, one is the change of momentum, and the other is the change of pressure. From the point of view of momentum change, simply speaking, the propeller accelerates the passing water, causing the water mome

The history of propellers can be traced back to the records in "Tiangong Kaiwu", which was found on the chariots of the Yellow Emperor. In the Tang Dynasty, Li Wei installed a human paddle wheel on the side or the side of the ship, called the "paddle ship" or "wheel ship" (this is the origin of the

Each model of the outboard engine has a variety of propellers for use. The matching of the ship, the engine and the propeller has an important influence on the boat driving, the ride comfort, the sailing speed, the fuel economy and the the engine life. In order to get the boat to its best condition,

From a 3-horsepower electric to Mercury Racing's new 450R, there's a lot happening with outboards. MERCURY RACINGOutboard motors tend to evolve at the pace of the Nile crocodile, which dates to the early Pleistocene and has minimal updates for the 2019 model year. But lately, there's been a lot of
