To maximize propulsive efficiency, propeller selection should be performed precisely on the basis of ship type, operation mode, and area. Propulsion efficiency, fuel consumption, robustness, reliability, emissions, vibration, cavitation, complexity and cost are investigated in both conventi...
The propeller efficiency will be highest for a propeller with a minimum number of blades i.e. 2 blade propeller. But to achieve strength factor and considering the heavy loads subjected by the ship, sea and weather two-blade propellers are not used for merchant ships. 3 Blade Propeller ...
The absence of propellers makes jet boats safer and more user-friendly, as there are no exposed rotating blades. This feature also enables them to operate in areas where traditional propeller-driven boats may encounter difficulties or risks. Jet boats are known for their impressive acceleration and...
in different types of turbomachines, such as steam turbines used in powerplants and compressors used in crucial pipeline applications. They're primarily employed in high-performance engines in the automotive and aerospace industries, but other low-speed applications like ship propellers also use ...

and living. It is a practical and cost-effective wind power installation platform. The vessel is equipped with 2 sets of 1,800kW all-direction propellers and 2 sets of 1,000kW all-direction propellers at the bow and stern. It boasts a DP1 dynamic positioning function, allowing for autonomou...
An aircraft under the powered lift category, such as the Bell Boeing V-22 Osprey, is capable of vertical takeoff, landing, and low-speed flight. An aircraft in this category depends on engine-driven devices (e.g., propellers) or thrust (i.e., a jet engine) for lift at low speed but...
