Key Functions of Aircraft Electromechanical Components

A small mind of the man has developed mind-boggling things. With that, life has become so much easier. And when looking at these things, aircraft shine. This development has allowed us to travel to any corner of the world within a few hours.  

Well, creating aircraft requires different components and interconnected systems. They all work together in a specific way. One of these systems is the electromechanical component system. 

With this system, aircrafts function in a proper way. That means it’s the electromechanical components of the aircraft that ensure safe flights.    

In this article, we’ll discuss these components and their key functions. 

What are Aircraft Electromechanical Components? 

As you know that a system is made up with different components. Same goes in the context of the aircraft system. 

As the name suggests, aircraft electromechanical components are devices that act as a bridge between electrical and mechanical components so they can interact with each other to perform a specific action. To put it simply, they convert electrical signals to mechanical movement and vice versa to make aircraft fly.  

If they don’t work properly, chances are the aircraft will face some serious consequences.

Examples of these components are motors, actuators, sensors, switches, relays, solenoids, and generators.  

What are the Key Functions of Aircraft Electromechanical Components?

These components perform their key roles for the better functioning of the different systems in aircraft. Let’s discuss all those systems: 

  • Flight Control Systems

The aircraft doesn’t fly in a straight position. You may have seen it when pilots tilt the wings and turn the aeroplane.  The real heroes behind this whole scenario are these aircraft electromechanical components. 

Their intervention helps in the functioning of the flight control systems such as cockpit controls, flight control surfaces, and engine control.  

As per the pilot’s commands, these components control any of the systems, and then the aircraft goes to the required position. 

Here, we can imagine how important they are because a minor fault in these components can make the aircraft out of control. 

  • Communication systems 

How it would be when an aircraft is being landed but the ground surface is not suitable for that. Of course the chances are more likely to meet accidents. This is the reason, the pilots stay connected with the ground crews to ensure the ground surface is safe to be landed.   

Aircraft electromechanical components keep the communication system such as radios, transmitters, and antennas working well. Because of that, there is a clear communication between pilot and ground crews.  

You might have watched a scene from any movie when a plane crashes. The pilot wants to send a message about a technical error to the ground crew. But their voices break in the radios. As a result, no one understands each other due to the malfunction of these components. And the plane hits the ground.   

  • Navigation Systems

The aircrafts have the proper airways to be on during flying in the air. That’s what navigation systems are made for. Navigation systems may include radar, GPS, and altimeters.  

You might also have seen when a pilot looks at the display screen to track their route. The navigation system provides every bit of information about that. Aircraft electromechanical components are the driving force behind the navigation systems.  

If these components are out of order, GPS will stop showing the route, and aircraft may get off course.  

  • Power Systems

The power systems give power to the previous three systems. Yes, it’s true that without power systems, communication, navigation, and flight control systems are useless. Any problem in power will surely affect the rest systems. 

Further, these components control the power systems, such as generators, alternators, and batteries.    

That means these components play an important role to ensure the aircrafts are reliable for a safe flight.

  • Cabin Environment Control Systems

We’ve discussed above that these components are helpful for pilots. But they go beyond that to give the comfort to passengers. How?  They create a comfortable cabin environment through the Cabin Environment Control Systems (ECS). 

ECS rely on sensors to continuously monitor temperature, pressure, and air quality within the cabin. Imagine when a plane climbs up, the pressure outside drops. These sensors monitor that change and ensure the cabin pressure stays comfortable for passengers by regulating incoming air. 

Samelike, if they detect any fume or smoke, they alert the system to take actions like increasing fresh air circulation.   

How do Electromechanical Components Work?

Well, aircraft electromechanical components work following the principle of electromagnetism. They convert electrical energy into mechanical motion to perform specific actions.

As an example, let’s talk about relay. When electricity flows through the coil of a relay, it generates a magnetic field. That further pulls a metal switch, completes a circuit and allows electricity to flow to another component.  

Similarly, we’ve talked about the sensors. As they detect any change in temperature, pressure, or air quality, they send an electrical signal to the aircraft’s computer. As a result, it changes the engine’s performance to make the environment suitable or comfortable.

In the case of a power system, generators produce electrical energy to store in the battery. Later, this energy is used for different systems, such as navigation and communication. 

Final Thoughts 

In conclusion, electromechanical components of the aircraft ensure the safe flight. Even a minor malfunction in them puts the aircraft in danger. They convert an electrical signal into mechanical movements and vice versa. These components include motors, actuators, sensors, switches, relays, and solenoids. Each of them takes a specific action to control different systems in aircraft, such as flight control, communication, navigation, power, and cabin environment control.
