Why are propellers in the front on airplanes and behind on ships?

The positions of the propellers best performance It is extremely important to give. Therefore, the positions of propellers in aircraft and ships difference shows.

on airplanes on the nose or wings The propellers are located in the rear part of the ships, on the other hand. In order to better understand the reason for this, it is necessary to evaluate the characteristics of the vehicles and the conditions they are in, respectively.

Pushing or pulling water?

Density of water relative to air 800 times it should be more. Therefore, it is easier to push the water forward rather than pulling the water.

The center of gravity of marine vehicles is very important.

In marine vehicles the propellers are connected directly to the engines via a shaft and the engines are very heavy. in front of a boat you don’t want to put heavy thingsbecause then when you get into the waves, the boat goes under the waves instead of rising above them.

Basically a boat pointed front And shaped that is why it is. The back is usually straight, while directing the waves down and to the sides.

What happens if we put the propeller in front of the rudder?

Recently, there are propellers on the front or near the front of passenger ships. But these propellers are not for ship navigation. 360 degree rotation capability Due to the berth, it is also to assist manoeuvring.

Because if you put the propeller just in front of the rudder, it will direct the propeller stream with the rudder while the engine is running. maneuverability you win.

It’s not without its risks that the propeller is in the lead.

When you put the propeller or rudder forward, you will bump into something in the sea that you may not notice. may be damaged and the main drive system will be damaged, so you can be completely disabled.

For submarines, the situation is somewhat different. The biggest problem for a submarine is underwater propeller noise due to being noticed. One of the most important factors to prevent this is that the submarine propeller is located at the rear due to its design.

Let’s get to the planes. Pushing or pulling air?

The situation on airplanes the exact opposite. It’s not that the propeller pushes the air because the air density is less than that of water must pull.

The position of the propeller increases the control ability of the aircraft.

Aircraft propellers, by their nature, produce a high airflow behind them. By directing this air directly over the wing and control surfaces, the pilot can assist the aircraft, especially at low speeds. more controllability provides.

Airplanes are not just forward, right, left, like ships; above And down It also has to move faster. In addition, the air drawn over the propeller at the front to the heating problem will also be a solution.

The era of propeller planes is slowly coming to an end.

However, with the rapidly developing technology today, turbine technology in aircraft; propeller airplanes for reasons such as efficient use and safety. has taken its place.

I guess front propeller planes are for us now. nostalgia or for hobby purposes They will remain as toys.
