Diffrence Between TurboJet, RamJet And ScramJet, Every Thing About Jet Engines

Summary

This video script offers an educational exploration of jet engines, focusing on the differences between ramjet and scramjet engines. The host, Kanth Ghosh, explains the basic functioning of jet engines, the types of turbine chat, and how they operate. He delves into the specifics of ramjet engines, which cannot propel an aircraft beyond the speed of sound, and scramjet engines, which are designed for supersonic combustion. The script aims to inform viewers about the various types of jet engines used in aircraft, from cargo planes to supersonic jets, and highlights the unique applications and limitations of each.

Takeaways

• 😀 The video is about explaining the differences between Ramjet and Scramjet engines, as well as discussing various types of jet engines.
• 🔧 Basic jet engines work by compressing air, mixing it with fuel, and igniting it to produce thrust.
• 🌀 Turbojet engines are described as having a fan at the front to draw in air, similar to a wing, and a turbine that compresses the air for combustion.
• ✈️ Turboprop engines are used in large cargo planes and are efficient for slower speeds but have limitations on speed.
• 🚀 Ramjet engines cannot accelerate an aircraft to zero speed but are used for supersonic speeds, where air is compressed by the aircraft's motion.
• 🔥 Scramjet, or Super Sonic Combustion Ramjet, engines operate with air moving at supersonic speeds through the engine, allowing for higher combustion efficiency.
• 🛫 The use of jet engines varies depending on the type of aircraft, with turbofan engines being common in passenger planes for their balance of thrust and fuel efficiency.
• 📉 Ramjet engines are limited by their inability to operate at subsonic speeds and require a certain speed to function properly.
• 💨 Scramjet engines are designed for high-speed flight, with air compressed to supersonic velocities, making them suitable for hypersonic applications.
• 🔄 The script also touches on the working principles of jet engines, such as the intake of air, compression, combustion, and exhaust.

Q & A

What is the main topic of the video?

The main topic of the video is to explain the difference between ramjet and scramjet engines, and to provide an overview of how jet engines work in general.

What is a jet engine according to the basic explanation provided in the script?

A jet engine is likened to a pipe where the front part is slightly wider, the middle part is slightly narrower, and the back part is wider again. It operates by compressing air, mixing it with fuel, and igniting it to produce thrust.

What is the role of the compressor in a jet engine?

The compressor's role is to compress the incoming air, increasing its speed and pressure, which is essential for the combustion process that generates thrust.

How does the script describe the working of a turbojet engine?

The script describes a turbojet engine as having an inlet that draws in air, a compressor that compresses the air, a combustion chamber where fuel is burned, and a turbine that extracts energy from the expanding gases to drive the compressor.

What are the different types of jet engines mentioned in the script?

The script mentions turbojet engines, turboprop engines, and scramjet engines as different types of jet engines.

What is a ramjet engine and how does it differ from a scramjet engine?

A ramjet engine is a type of air-breathing jet engine that operates by taking in air at subsonic speeds and compressing it through a diffuser. A scramjet engine, on the other hand, operates with air moving at supersonic speeds, and it has a design that allows it to compress air effectively at these high velocities.

What is the purpose of the afterburner in a jet engine?

The afterburner is used to increase the thrust of a jet engine by burning additional fuel in the exhaust gases, thus providing more energy and increasing the speed of the aircraft.

How does the script explain the term 'turbine' in the context of a jet engine?

The script explains the turbine as a part of the jet engine that extracts energy from the high-velocity gases produced by the combustion process, which is then used to drive the compressor.

What is the purpose of the diffuser in a ramjet engine?

The diffuser in a ramjet engine slows down the incoming air to subsonic speeds, increasing its pressure and allowing it to be compressed and used for combustion.

How does the script differentiate between the use of turbojet engines and turboprop engines?

The script indicates that turbojet engines are used for higher speeds and are common in passenger aircraft, while turboprop engines are used where there is a need for more thrust at the cost of speed, such as in cargo planes.

What is the significance of the term 'inlet' in the context of the video script?

The inlet is the part of the jet engine where air is drawn in. The script explains that the shape and design of the inlet can vary, affecting the amount of air that is drawn in and how it is compressed.
