How Are Ghost Planes Not Caught on Radar?

How are stealth planes, one of the biggest focuses of the aviation world, not caught by enemy radars? Let’s take a closer look at these planes, for which hundreds of billions of dollars are spent every year.

Although airplanes are still a new technology for the history of humanity, they have become the most important vehicles in the military field, as well as in civil aviation. While dominance in the air can even determine the fate of a country, countries can of course also their investments in aircraft. is increasing rapidly.

If it is one of the most mysterious and scary concepts in aircraft technologies, ‘ghost planes‘ was. So, how do these planes, which hide themselves from their enemies in the sky, actually work? What is the logic of ghost planes?

What is a “Ghost Airplane”?

Contrary to the perception we have when we hear the concept of ‘ghost’, ghost planes do not mean that these planes are invisible to the eye. The term ‘ghost’ is used in the military field not only for airplanes but also for ships, tanks and all kinds of vehicles. ability to hide from enemy systems that you have it states.

Therefore, stealth planes are airborne, completely focused on concealment from enemy systems. aiming to catch the enemy by surprise and warplanes focused on non-targeting.

How do ghost planes stay hidden?

Some general techniques and methods used in other stealth vehicles are used to hide the ghost planes. The system that the planes really want to hide is the enemy radars. one side hide from radar systems with eyes and ears in the air and on the groundallows entering the airspace and detecting/destroying targets without even the spirit of this party.

A variety of methods are used to ensure that stealth aircraft are hidden from radars. But before we move on to the stealth methods used on airplanes, how the system you want to hide works It is useful to summarize briefly.

Let’s learn how the radar works:

radar

Conventional radars, which can be found on the ground and in land, sea and air vehicles, are periodically sent to the environment. electromagnetic waves sending. The fact that these waves hit somewhere and reflect back to the receivers indicates the presence of a unit around.

The electromagnetic waves that are sent and returned to the receivers are analyzed by computers and The angle of return of the wave is relative to the intensity and velocity of the returning wave. The location, direction and type of the unit in the area can be determined.

So, how do stealth planes hide from radars?

Ensuring that the ghost planes are hidden from the radars is basically the electromagnetic waves reflected on the plane. prevent it from returning to buyers passing. In this context, aircraft manufacturers can use different methods to deflect electromagnetic waves in different directions or to ensure that the waves are absorbed by the aircraft. Some of these methods are as follows:

Physical structure of the aircraft:

When you look at the F-16 and other considered ‘standard’ warplanes, the fuselage that it does not include very sharp structures. you can see. This design, which is used in airplanes, is especially used to minimize the resistance in the air and therefore to increase maneuverability and speed.

But the situation is different for stealth planes. When you look at iconic stealth planes like the F-117 panels that are much more angular, straight and positioned at irregular angles you can see. Although the flatness of the sides and the surface in the aircraft design reduces the aerodynamic capability, it allows the electromagnetic wave from conventional radars to be reflected at different angles and to distant points from the receivers.

With this design, radar waves that can be reflected back from the aircraft can be seen on radar screens. It leaves only a trace as a bird. Because the other waves coming to the plane are bounced in very different directions.

Wave absorbing materials used in the fuselage of aircraft:

The most critical concealment methods used in ghost planes appear in the materials used on the plane. Aircraft manufacturers have spent billions of dollars over the years researching and developing surfaces and surfaces that will enable them to hide planes from radar. especially paints is developing.

Dyes, which are used as the most common hiding material today, will allow the waves to be absorbed. to special microscopic structures gives place. These triangular structures, which you can see in the image above, ensure that an incoming radar wave is trapped in the structure and eventually loses its energy in a jerk. Thus, either a very weak wave or no wave remains from the reflected wave.

Reducing the thermal footprint of the aircraft:

Speed ​​is one of the most important factors that makes an aircraft visible to radars and other systems. heat generated on the aircraft surface and emitted from the engines is happening. Aircraft manufacturers receive support from special materials and paints to reduce the heat generated on the aircraft surface by air friction.

But when it comes to the engine, there are solutions that create some disadvantages. Ghost planes are deprived of technologies such as ‘afterburner’, which allows planes to reach high speeds, engines run at much lower power. Although less heat is generated in this way, it greatly reduces its maneuverability in dodging enemy units if they are detected.

Of course, new engine technologies are used to reduce the heat trace in the engines. financially costly and comprehensive studies progress.

So, is there no way to detect these planes? Of course there is:

Just like on the internet hackers with white and black hats There is the same relationship in stealth planes as in the relationship between Countries are working on new technologies to detect enemy stealth planes in order not to be caught by surprise.

Some of the methods used to detect stealth planes today are as follows:

  • low frequency radars,
  • Electromagnetic wave receivers located in multiple locations
  • Advanced systems used to detect the temperature of airplanes (After all, the temperature in airplanes can never be the same as the sky)
