Which are most needed in fighter and supersonic aircraft, the name of turbofan engines is left behind. In order to meet this need of these specific aircraft, the name of jet engines comes to the fore, which are generally used in fighter aircraft to meet the speed reduction. 

With a few changes, this engine is also a part of the gas turbine engine family and to generate intense thrust, with a few important changes, they resort to gas exhaust while going through the above steps. To meet the speed and desired thrust, air is introduced into the compressor without any obstruction. This process, along with generating abundant thrust, also causes a loud sound in the form of gaseous emissions.

"Here we will tell you to increase your knowledge that a jet engine usually completes 166 phase cycles in one second to produce constant thrust." Today, these turbojet engines are seen in fighter jets like F-104, Mirage III and MiG-21.

So, This was the mention of these jet engines, some of which work silently and very fast, and some also produce noise with intense thrust, but there is also an engine of the same family, which despite being a jet engine, has the ability to fly low with the use of a fan to produce thrust. 

Yes, We are talking about the turboprop engine, which is used only for low-speed flight. This engine of the jet engine family is generally used only in a few military aircraft, such as Lockheed C-130 Hercules and P-3 Orion, etc.

This engine, like other engines, produces thrust by going through various practical steps, which starts with the air entering through the front part of the engine. From here, it is transferred to the compressor area. This part consists of blades. The purpose of these blades is to increase the pressure as well as the temperature of the incoming air so that it can be used to burn fuel. 

Later, this hot air is transferred to the combustion chamber where fuel is added to this hot and compressed air through nozzles. Here, a park plug is used to start this process and thus, combustion begins in this part of the engine, which causes the turbine blades to rotate. But wait, does this process complete here? 

It is not like this,  As we have already told you, this engine takes the help of external blades to produce thrust. Here, the speed of the turbine rotating inside the engine is at least twenty thousand revolution per second, which is faster than any propeller. Therefore, here the speed is transferred from one thousand to two thousand per second using a gearbox to reduce the speed of the blades.

In the end, we would just like to say that today the status of the engine installed in the aircraft is much more than a mechanical system, perhaps equal to the human heart, which is sometimes convinced to work with silence and intense noise, whose change is being seen as the first priority for aircraft today, whether it is on the battlefield or traveling miles. Today, due to the reduction in environmental pollution, these engines are being further improved and made environmentally friendly, thanks to which these engines are seen playing an important role in making the travel of aircraft better and easier for passengers in the coming times.

Today, in wars between different countries, fighter jets have the status of changing the map of war on the battlefield, which, along with spying on the air borders of the opponents at very high speed, often easily target their targets. During the recent Indo-Pak war in the South Asian region, many such videos were kept under observation in which the modern fighter jets flying not only forced the general audience to applaud the pilots but also highlighted the names of several aircraft manufacturing companies.

But the question arises whether the pilots sitting in the cockpit are the only ones behind these expert maneuvers of these flying aircraft or is there an equal role in modern design and technology?

From the perspective of an expert engineer or pilot, the answer would be this: "It is a combination of the latest technology and the skill of a pilot who, under the electric strategy, uses the thrust vectoring, aerodynamic and propulsion technology present in these modern fighter jets to produce excellent results."

In general, the maneuverability of any aircraft depends almost entirely on aerodynamic control surfaces such as ailerons, elevators, and rudders, which play a key role in changing the direction, pitch, and yaw of any aircraft with the help of airflow. However, these surfaces have their limitations, Especially at high angles of attack or low airspeeds where the airflow becomes turbulent or separated. But in modern fighter jets, another advanced technique plays all the roles, called thrust vectoring in engineering optimization, which aims to allow these aircraft to perform difficult maneuvers, land and take off vertically, and achieve excellent control of the aircraft at low speeds.

This process of thrust vectoring is as simple as it sounds, but it is also as difficult as it sounds. Here, instead of the outer part of the engine, this process takes place in the inner core of the engine, where the thrust vector force is redirected and transferred at different angles so that the fighter aircraft can be pitched, yawed and rolled easily and quickly. In some jet engines, this process is facilitated with the help of nozzles, in which different types of nozzles are used, such as two-dimensional nozzles, which aim to move the aircraft quickly up and down, and three-dimensional nozzles, which aim to move the aircraft in different directions -

But this modern process is not limited to engine thrust and nozzles. In current fighter aircraft, to simplify this complex process, it is connected to hydraulic, electrical and digital control systems. 

This system works exactly according to the commands given by the pilot, and the flyby With the help of wire technology, the thrust vector is better controlled at the exact point where the engine speed requires extraordinary attention, a major reason for which is the intense temperature of the gases emitted from the engine. According to a conservative estimate, this temperature is up to 1500 degrees Celsius during normal flight, which can prove harmful to both mechanical and electrical systems if uncontrolled.

So sir, till now we have known what is thrust vectoring and how does it work better than the main components in modern fighter jets?

Let's know what are its advantages and disadvantages. As we all know, all modern fighter jets have a few objectives, keeping in mind which fighter jets like SU-35, F-15, F-22 Raptor and JF-17 have a prominent place, one of the main reasons for this is the modern technology like thrust vectoring present in them, which not only gives them an edge over other fighter jets in various air dogfights, but also improves the take-off and landing performance of these aircraft by reducing the required length of the runway. In addition, due to thrust vectoring, stability also increases during low-speed flight.

However, while this thrust vector system has many important advantages, it also has some disadvantages. The most important disadvantage is that during the war, due to the use of fuel, there is a huge increase in consumption and a sudden increase in temperature, which can make it an easy target for infrared weapons. In addition, due to this system, the aircraft also faces problems such as an increase in weight and an increase in price.

Finally, it would not be wrong to say that despite all the complexities, thrust vectoring in modern fighter aircraft today is a modern aerodynamic technology and provides special assistance in moving quickly and trying out maneuvers during the war, provided that the pilot is also skilled in flying modern aircraft.
