Jet and Turboprop Engines Explained: Understanding the Heart Behind Modern Flight (Part 2)
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.
