Ship propeller: A propeller (or ball) is a gear used to propel a ship or aircraft. Power transfer cycle by converting movement into pressure.
When pressure is applied to a vehicle such as an airplane, ship, or submarine by turning two or more arrows, the air is moving.

The propeller blades act as rotating wheels, generating a force that enforces Burnley's principle and Newton's rules of motion, creating a pressure difference between the epoxy surface and the burner pumps.
ELICA boat
 |
| ball boat ball |
A horn is a tool used to put pressure on a ship.
The packing is driven by a shaft driven by the main engine in the engine compartment.
Package type:
• Fans whose leaves are still open.
• The packed balls are modified by the plaintiff with a nozzle.
• Rotating blade fan (fan with adjustable volume).
• There are other payment methods besides this one.
Packaging design;
There are many ways to design a soccer field:
- Realization of experiments with balls with Cavity Tunnel.
- Graphical use of heavy models (tens of fan models drawn at different speeds, etc.).
- Using the method taken from statistics (again).
Use of CFD calculations.
loss (loss)
- Not all the pressure created by the ball is used to move the boat due to the loss in the ball.
- Sealed rods have handles and seals that lead to loss due to the problem.
- Not all the energy generated by the combustion of the fuel is converted into energy in the output shaft of the main engine.
Light:
Improper ball design, also known as a puncture event, water vapor bubbles can reduce the pressure drop across the ball and damage the ball.
Types of ships (ships)
1. Except for the fans
Straight-Stroke Straight (Strip-Straight, FPP) is used for larger boats with relatively low speeds and high motive power, cheaper fuel consumption Noise, less or less noise, often by design The boat has special features, which will have a good value proposition.
 |
| The fan is a fixed level. |
Flexible Pitch Adjustable Propellers (Controlled Propellers, CPP) are sliding balls with adjustable blade strokes.

For example, for low speed, use a large step and use high speed, or use it to push forward and pull the ship back, which is useful to see the use of a buckwheat stallion.
 |
| The fan is an adjustable level. |
Propeller and steering (propeller and steering are additional).
Integrated Propeller & Radar, HIV Propeller and Lead Center, is under shipbuilding development.
 |
| Integrated fan and leader |
Conditions that cause air to flow through the steering wheel, also known as increased control and steering arrangements, which reduces fuel consumption. (Improvement and control of steering and reduction of fuel consumption).
Adjustable Bolt Fan (Adjustable Bolt Fan).
 |
| Adjustable boom bolt |
This type of ABP fan is an FPP. It is a development, the razors can be operated individually, and then installed on a Windows fan.
 |
| Different parts of the fan with adjustable bolts |
Therefore, it is possible to prepare sheets individually, minimizing production costs (die/mold required) to prepare the lowest value (simplifying the loading process for more efficient code matching).

2. Azimuth thruster
 |
| addition of azimuz |
The azimuth tractor is used to facilitate the movement of the ship but it is fed by the pressure of the chamber and therefore the eighth element is placed to store the main pressure, diesel engine or electric motor.
3. Electric capsule
 |
| electric ball |
Use of a 5 to 25 MW electric motor instead of the traditional shaft and steering propeller. Pod technology allows the fan to be housed in an excellent airflow zone (optimized for hydrodynamics).

By placing the electric motor in the pod outside the chassis, the pod fan is taken from the azimuth fan.
4. Tone pressure
 |
| tunnel pusher |
Portable and Strens/Bow Thruster that can be used almost anywhere, making it easier on boats, especially ports.
5. Water spray
 |
| Water pumps |
The boat's propulsion uses a pump that pulls the water in and pushes it forward.
Engines ranging from 50 kW to 36 megawatts are more efficient propulsion for ships over 25 kW.
6. Foith Schneiders fan
 |
| Fan Voith Snyder |
Voith Schneider Propeller is a type of boat that uses discs that spin like a disk and then move the beams against the boat.
The system works in the same way as the fan pec control unit (common volume control).
As the gears of this drive rotate over the ground, the angle of attack of each blade (in the form of a hydraulic blade) changes.
