Jet Engine, How it works ?

jet engines have been the successful drivers of aircrafts for nearly a century now in This video we will explain the technology behind the jet engine in a logical step-By-step Manner a jet engine keeps an aircraft moving forward using a very simple principle The same that makes an air-filled balloon move Yes, Newton’s third law of [motion] just [like] the reaction Force produced by the Air moves the balloon The reaction Force produced by the high speed jet at the tail of the jet engine makes it move forward so the working of jet engine is all about producing a High-speed jet [at] the exit the higher the speed of the jet the greater the thrust force The thrust force makes an aircraft move forward Such high-speed exhaust is achieved by a combination of techniques If you can heat the incoming air to a high temperature it will expand tremendously and will create the high velocity [jet] For this purpose a combustion chamber is used An atomized form of the fuel is burnt in the combustion chamber effective combustion requires air to be at moderately high temperature and pressure To bring the air to this condition a set of compressor stages are used The rotating blades of the compressor add energy to the fluid and its temperature and pressure rise to a level suitable to sustain combustion The compressor receives the energy for the rotation from a turbine which is placed right after the combustion chamber? The compressor and turbine are attached to the same shaft The High-energy fluid that leaves the chamber makes the turbine blades turn You can see that the turbine blades have a special airfoil shape which creates lift force and make them turn As the turbine absorbs energy from the fluid [its] pressure drops Through these steps we have achieved our objective a really hot and high-speed air emitted from the exit of the engine the engine case becomes narrower towards the outlet which results in even greater jet velocity In short the synchronized operation of the compressor combustion chamber and turbine makes the aircraft move forward Modern aircrafts use a slightly [improved] compressor turbine arrangement called a [two] spool Here two independent turbine compressor stages are used the shaft of the outer compressor turbine passes concentric [LI] through the inner one The outer turbine is subjected to a low energy fluid and will run at a lower speed than the inner turbine Low pressure blades are longer this [low-speed] helps to reduce centrifugal stress induced at the root Thus improving the blades life Some modern aircrafts even use a three spool engine The engine we have discussed so far is more specifically called as turbo jet engine Turbo jet engines tend to Produce high levels of noise [A] Revolutionary Improvement was made to this engine by fitting a large fan with the low pressure spool such engines are called Turbofan engines and almost every commercial aircraft run on them a Turbofan engine bypass is a huge amount of air The ever narrowing bypass duct provides a good jet velocity to the bypassed air in a turbofan engine the majority of the thrust force comes from the fans reaction force further the fan greatly improves Airflow in the system by sucking in more air Thus it helps to improve the thrust This means high thrust creation with an expense of slightly more fuel This is [the] reason why Turbofan engines are highly fuel economical The noise produced by a jet engine is highly dependent on the exit jet velocity Since in a turbofan the bypassed cold air gets mixed with the hot air it is possible to keep the outlet velocity within a limit Thus it overcomes the noise problem With quieter exhaust and better fuel economy the turbofan engines continued to dominate aircraft propulsion systems We hope this provided a nice introduction to the working of jet engines.

  2. Am I the only one that sees the blades are moving in the wrong direction?

  3. Hey can you people make out a video lecture on WHAT ARE THE PRINCIPLES AND MECHANISM OF ELECTRIC UNICYCLE which is a predominant upcoming ideal vehicle on roads.
    Your practical video lectures help us to understand and learn quick.

  4. He talks like “what I’m saying it’s so obvious, I need do career-hopping bro”

  5. Sort of correct but truly awful, how on earth was this created?

  6. How to produce the combustion inside the chamber combustion and how to rotate the shaft?

  7. didn't actually explain at all the purpose or function of the turbine section at the rear.

  8. I always wonder with 2~4 turbine a plane can fly. How much energy is produced by them in terms of ground transportation?

  9. Hm i still don't really get it. I would like to know why the combusted fuel, combined with air propels the engine forward. What's the difference with regular propellers?

  10. Are you sure they've been a successfull driver of aircraft for nearly a century?

  11. Didn't v run da tea shops or Barbara kadai saloon 😍 show da great poster of The Royal casino it's true machi n can b proved 👍😍

  12. 0:20 "the same way an air filled balloon moves," me: displacement? "Exactly, Newtons 3rd law of motion."

  13. Here’s a way to remember it:
    “Suck, squeeze, bang, blow.”
    Intake, compression, combustion, exhaust

  14. Yes. The front blades indeed appear to be pitched reversely, to judge by the displayed rotation animation throughout this video. The correct pitch is at last shown briefly at the very end of the video; at about 5:20 min/sec. Thank you very much for taking the time and effort to post this very enlightening video. We appreciate a well-organized and clearly explained documentary. We look forward now to another video that may deal in the Electrical aspect of these same mechanisms; such that explains the Starting System, from beginning to end, perhaps. The Fuel and Acceleration System would also be quite an interesting video to watch, to conclude the understanding of the entire system in basic fundamental concept. Thanks again.

  15. น่าจะแปลเป็นไทยด้วย

  16. Jet technology is 100 years???? Wrong it started in the 40s with Germany.

  17. so basically, it does the squeeze to the air, squirt the fuel, the fuel and air become friends and come together, ignite and push the plane so it go fly?

  18. I am now putting the Sindhi version of this video on my channel from this account. Earlier, I had uploaded from my account ahsanahmadursani. I have now published it on my new channel:

  19. Hi, I am already your partner. I have uploaded Sindhi translation of this video on the following link. I do not see any reason for the copyright strike. I had been allowed by you to do translation and upload.

  20. Outdated jet engines. We need an upgrade so we can all fly supersonic or faster.

  21. say thank u to the Romanians People! One man from Romania has created the Jet Engine!

  22. So do you start this engine with a pull cord like a lawnmower? The combustion chamber only works when the compression blades are turning? So if you pull the starter cord to get the blades turning do you light a match to ignite the combustion chamber? Will this fit on my bycicle? My mom doesn't let me play with matches. Guess I'll be a astronaut when I grow up unless you need a match to start a rocket engine? Maybe I'll just make matches when I grow up.

  23. Wow!! This video is educational!! Proud bisdak here…. this channel is superb!!! Pls visit my channel too. Lets be friend! Mga kababayan halikayo sa channnel ko. Wag kalimutan sundan aq for more videos. Salamat

  24. Why pressure is need to be dropped by turbine because high pressure high speed

  25. Can someone explain why the thrust go one direction? Not both direction? I understand the air comes from the left, but the burning of fuel is in the open chamber. So the jet should thrust in both way.

  26. Thank you for providing this video. I thought that was very cool Kudos

  27. This video watched. I understand how are worked jet engine. Thanks for Internet and Channel mentor,,

  28. Nice

    You can visit our YouTube Channel for 3D animated process animation videos.

Our creative designers transform the complex or mundane processes into superbly sculpted 3D models with vivid visualization and presence.

  29. It is not rotating in the wrong direction……..have you ever watched any high speed wheel or rotor in motion……if you look at it close there is an optical illusion of it spinning backwards, slowly, that could be what this is.

  30. Rollce royle versus General Motor
    Witu General Electric
    GM and GE and rollce royle

    What a game point?

  31. No fuel, its compressed air technology. F1 cars are the same.
    Brainwashing the public with the fuel bullshit.
    Free energy being hidden from us.

  32. Why is the first frame of the video a Boeing 747-400 with 2 engines and not 4?

  33. lol those blades are spinning incorrectly, it isnt taking the air in because going the other way you look at the blades, then you can tell the air is going in…

    not in this case.

  34. They're spinning in the opposite direction because it's reversing, sharks do the same in fish tanks.

  35. blade is running with a wrong direction。

  36. It is worth mentioning that Turbofan engines used this days everywhere does not produce Condensation Trail ( )

  37. Jis tarha ap ka jet engin ka fan rotate kar raha is tarha air pachi ni agay move kara gi,, phala khud principal samag phir dosro ko samga

  38. Fighter jet engines are either afterburning turbojets of afterburning TurboFans with low bypass.✈ Fan blades, compressors, combustion chamber, turbines and a shaft to drive the compressors. GTF Geared TurboFan.

  39. Fast forward to 21st/nd century. so how does an Electric Jet Engine Work? Why are they more efficient in high altitudes than regular internal combustine jet engines?

  40. Tôi là người VIỆT NAM vô đây để học hỏi kiến thức . Video rất hay và bổ ít👍👍👍👍❤❤❤

  41. O compressor está girando ao contrário. Sei que é só ilustrativo, mas…

  42. if a Jet engine is less complex than a reciprocating engine…why is it so expensive and costly to maintain? or is it just the fuel consumption that's more costly?

  43. Crazy that those compressor blades are able to hold up to those temperatures

  44. I know how to make it even faster….1000x faster…#futuristic hit me up
