Why Do Drones Often Have 4 Propellers?

Especially in recent years, it has brought great convenience to different sectors. of drones there are many varieties. In this context, we see that their shape and number of engines change according to their intended use, but for some reason the most common ones are four-engine models appear.

So what’s the reason for this? Four-engine models are better than those with fewer engines. making it good or for those with more engines preferable Have you ever wondered what causes it? Let’s look behind this issue together.

Let’s start with single-engine drones:

To fly the drone engine and propeller Both are indispensable. But the job isLet the engine spin the propeller and let’s fly smoothly“It is not easy enough to say. As the motor turns the propeller in the opposite direction develops a torque.

At this time, your drone takes off, but due to the torque we mentioned, it is constantly revolves around itself.

We are familiar with this thanks to remote-controlled helicopters:

These toys, especially the cheaper ones, are, as we are used to when they take off mostly revolves around themselves.

In order to prevent this, manufacturers have turned to toy helicopters, as we can see more commonly these days. two engines places it.

Because the two engines rotating in opposite directions cancel the effect that causes the helicopter to rotate around itself.

For this reason, your toy does not rotate around itself and avoids the risk of hitting something. give directions greatly facilitated.

If one propeller rotates clockwise, the other propeller on the contrary rotary. In this context, when you want to turn right, the motor moving to the left slows down and your toy turns to the right because the power of the one going to the right is dominant.

Just like when you let go of the left paddle and pull the right one while rowing, the boat turns to the left.

In this scenario, when you use only two paddles, the rotational status you can avoid.

When we put the toys aside and look at real helicopters, we see a big propeller. Then why don’t they spin around themselves?

because in helicopters The task of the second engine that we have just mentioned, the one located in the tail part and vertically built engine.

This engine provides a stable flight experience as it works in sync with the engine of the large propeller most of the time.

forward and backward maneuvers You can check out our content below to learn how they do it.

Once we understand this, let’s get back to drones.

Same logic to fly the drone properly. at least two engines needs. When we wanted to steer the drone, we said that one of the engines was moving faster than the other.

In this context two motors drones are mostly ‘Dihedral Since it is designed, it offers the possibility of movement in only two directions. In addition, we cannot say that they are very resistant to even the slightest winds.

Which brings us to 3-motor drones.

In these models more balanced a flight experience. But still, do not have a flying experience that will make you forget the two-engined ones.

Although they are much more performance and balanced than them, 3 motor drones can also be used. with the wind not good. But as a plus, there are possibilities of movement in more directions.

As for the four-engine drones that hold the throne…

The biggest plus of these models is that you can get better performance with more engines. price performance being overly efficient.

The state of rotation due to the torque we mentioned at the beginning; two engines clockwisedisappears with the other two motors turning counterclockwise.

In addition, since there are more engines than the previous ones, load carrying they do not upset the users in such tasks.

In addition harsh weather conditions These models, which have the potential to perform better than other models, are also very rich in terms of movement direction.

In short, in order to get the efficiency we want, the most efficient, most durable and reliable in terms of price / performance. most performing We can say that the models with four engines are those with four engines.

Yet there is more:

When you look 6 or 8 propeller drones You can also see. These models can often be seen by professionals during filming or search and rescue operations. For this reason, the prices are quite high.

In exchange for prices extreme endurance and balance they provide. Of course, extra propeller means extra engine, extra engine means extra power consumption.

So while adding an extra engine improves the experience, will increase the costbattery life will reduce. Therefore, individual users do not prefer these models.

Of course, these are just drone types. Because one company’s 3 propeller drone is different from another company’s 4 propeller drone. can be better. But when the conditions are the same, this is not the case.

For this reason, everyone chooses the drone model and brand, taking into account their needs.
