Propeller
A propeller is a device that relies on blades to rotate in air or water to convert the rotational power of the engine into propulsion. There can be two or more blades on the hub, and the back side of the blades is a spiral surface or a spiral surface. propeller. There are many types of propellers and are widely used, such as propellers for airplanes and ships.
Side Thruster
Side thruster refers to a device that assists the ship's steering. Generally, it is a propeller driven by an electric motor in the transverse pipe of the bow, which can discharge water on one side to the other side, and assist the steering of the ship by the reaction force of the water. When the ship leaves, docks or sails at low speed, the rudder has little effect, and the thruster can improve the maneuverability of the ship. Some are equipped with side pushers at the bow and stern to move the ship laterally or steer on the spot.

Geometric parameters
Diameter (D)
One of the important parameters affecting the performance of the propeller. In general, as the diameter increases, the pulling force increases and the efficiency increases. So if the structure allows, try to choose a larger diameter propeller. In addition, consider that the airflow velocity at the tip of the propeller should not be too high (<0.7 speed of sound), otherwise shock waves may occur, resulting in reduced efficiency.
Number of blades (B)
It can be considered that the tensile coefficient and power coefficient of the propeller are proportional to the number of blades. Ultralight aircraft generally use double-blade propellers with a simple structure. Only when the diameter of the propeller is limited, the method of increasing the number of blades is used to make the propeller and the engine get a good fit.
Reality (σ)
The ratio of the area of the blade to the area of rotation of the propeller (πR2). Its effect is similar to that of the number of blades. The tensile coefficient and power coefficient increase with the increase in solidity.
Blade angle (β)
The blade angle changes with the radius, and its changing law is the most important factor affecting the performance of the propeller. Traditionally, the value of the blade angle at 70% of the diameter is the name of the blade angle. Pitch: It is another way of expressing blade angle.
Geometric pitch (H)
When the angle of attack of the blade profile is zero, the distance the blade travels through one revolution. It reflects the size of the blade angle and directly points out the working characteristics of the propeller. The geometric pitch of each section of the blade may not be equal. It is customary to use the geometric pitch at 70% of the diameter as the name value. Propellers can be ordered according to diameter and pitch abroad. For example, 64/34, it means that the diameter of the propeller is 60 inches and the geometric pitch is 34 inches.
