One question that I have and would appreciate if someone could answer for me....what is the major difference of having a turbojet and a turboprop?? Other than speed?
@gmt2183 Fuel consumption would be much less in a turbo prop and efficiency would be high, because of the high bypass ratio. Most of the thrust is generated by sucking a high mass of air and just pushing it back without burning any fuel. But the disadvantage is that unlike turbojet, size of a turbo prob would be huge and it will create a lot of noise as the propeller is not shielded inside a nacelle.

Hey, can you tell me how jet engines are able to work in conditions such as flying through rain? I have always wondered how they are able to work in wet conditions.
It's impossible that man made something like jet engine. That means it must be made by god. People just probably find it on a field or somewhere else many thousands years ago or something.
@Ahha794 Yep, the air rushing from the combustion chamber through the turbine, drives the compressor via a shaft. This is why, to start a jet engine, you must pre-spin the engine, using the aircraft's APU or a ground starter, to spin the combuster enough allow it to suck in enough air to allow combustion in the combustion chamber.
what would the effects be if you added propane to compressed air in a metal container and ignited the exhaust valve of this mixture. I have been looking at water rocket and sawa asian guy lauched over 20 ft and have thought abotu ways of launching a glider or huma powered aircraft

yes I found a site where you can VALUE YOUR YOUTUBE CHANNEL (or web or blog) and you get help on how and where to sell it so you can make some good money with that !!! site is mysitemymoney . com
Exhaust cone is big at the start and tapers to nothing. The area inside the exhaust, increases, and it slows the air flow for noise abatement. The exhaust structure is called the "common nozzle" because it mixes the cold bypass air with the hot turbine air. For noise abatement. It is OK to cool and slow the exhaust air in order to quiet it down, because most of the thrust of a modern turbo-fan engine is produced by N1. N1 refers to the fan blades you see at the very front of the engine.
He mentioned the exhaust nozzle. The exhaust nozzle is very important for how it handles the exhaust stream and it's noise abatement qualities. People look at the exhaust nozzle and assume that it converges and excellerates the exhaust. But even though it converges, the exhaust stream actually diverges and slows. This is due to the shape of the exhaust cone. Exhaust cone is big at the start and tapers to nothing. The area inside the exhaust, increases and slows the air flow. For noise abatement.
Don't listen to the narrator, it isn't simple at all. LOTS of men have died finding the faults with the prototype and early jet engine designs which has led to the remarkably reliable turbo-fan engines in use today. Today's jet engines are made of space age materials and controlled by advanced digital and analog computer technology. The airframe is on a maintenance plan and the engines are in a WHOLE other world. They are looked at seperately and more closely and sometimes in real time.
@Drake14161337 An Afterburner is when you dump more fuel into already combusted air and light it up again with no new fresh air, which makes it an Afterburner. so yeah, I guess its the same thing! Damn engineers gave it many names probably to confuse us (kidin) ... and it worked :)
Okay I have a question then about this: mil. jets like the F22 have turbofan engines. These engines are streamlined (much smaller cross section than jetliner engines) and are used for supersonic flight. But this vid just said that's what turbo jets are for, not turbofans. Can anyone clarify this? Thanks.
@Graywolf116 The video is right, modern fighter jets prefer the greater economy and lower Infrared exhaust of a turbo fan engine rather than the greater performance of a turbo jet configuration.
@logelamutp 2nd time I've read this in a week, where are people getting this idea that the Germans or a German invented jet engines? Is it the Me-262?
I wonder why the energy used by the turbine doesn't make the compressor obsolete. The energy put into the air by the compressor should be the same amount as the turbine uses from the air stream. I know it works but I wonder where's my error! Hope someone can tell me
@assailant85 Fuel mixed with the compressed air is what makes up for the energy the turbine uses. Once you add fuel to air that highly compressed, it explodes and releases more energy than would be possible by igniting the fuel at regular atmospheric pressures. The expansion of those exploded gasses is channeled to drive the turbine and propel the engine by thrust and the cycle keeps continuing. Hope that helps some. :)
@gonzo5648 hmm...it's obviously correct what you say but it sounds a bit like a perpetuum mobile. the turbine creates more pressure thus more thrust. this thrust turns the turbine even faster -> more pressure -> more thrust and so on... Somehow there's something missing for me. You know what I mean?
I don't understand how the potential energy created by the turbine (through higher pressure) can be higher than the energy the turbine is consuming.
@assailant85 I get what you're saying. I'm no physicist but it seems to me it has to do with harnessing expansion ratios and channeling them. Look up some videos or read about how diesel engines work. That might give you an idea of how highly compressed gas PLUS fuel creates energy. Diesel engines and jet engines both use the idea of compressing air to explode fuel so that may help.
@assailant85 well because the energy is not created by the turbine... its created by the explosion of the mixture (fuel in a proportion with oxygen) this explosion releases thermal energy that is way more than the energy produced from the turbine...
@Emeengor hmmm yeah, sure, but the energy in the same amount of fuel remains the same. the bigger energy results from the compression of the turbine, not from more fuel or oxygen.
@assailant85 no listen for example in order to have compressed air like 15 times more than normal you need lets say 100 J of energy (just a number for the example) but the energy that gets release from the explosion is like 700J most of it doednt get to be used as work...
in other words the compression doesnt "create" energy it just makes the conditions that we need to create energy to happen. the explosion creates energy.
the potential energy in the fuel/air mix is let's say 100J, without compression only 20J is set free, with compression 90J is set free. For the compression you need only 10J which is set free again as 10 of the 90J set free completely. correct?
When using reverse trust, is it possible to get a surge in the engine jet? Meaning that the hot air returns back in the engine and damaging the engine. Surge is big risk for jet engines.
What thing ignites the fuel there in the combustion chamber? Can you please explain? Is it just the high compression of the air or something like spark plugs in a petrol IC engine? I am an automobile engineering student and i am very much interested in different types of engines. I really found this video very helpful. I now know more than most of the people around me, thanks to the video.
I understand everything but get a little stuck when it comes to the rotor and stator blades. I don't see where the stator blades are and would kind of prefer a better explanation on how this compresses the air.
@LittleBigFran The amount of air that the compressor can take is determinate by the air inlet duct.You can see that the stages are big at the beginning and getting smaller at the end of the compressor.So as the same amount of air is passing through the stages and the space is getting smaller the air pressure is getting higher.
(a row of rotor+stator blades=stage)Hope this helps
@azoj9 i dont no where ur getting ur info from but the turbojet was developed by Sir Frank Whittle, a British. Also credit is given to Hans von Ohain, a German. Now of course no one denies that none of this could be possible without the first ever aircraft flight which was done in 1903 by the Wright brothers, Americans
@SpaceMarine1986 Americans don't hate Canadians... It's just the country is kinda fun to poke fun at. Why? The country is so much like America, relatively new, no long epic history stretching thousands of years... And yet wasn't a key player in WWII, Vietnam, WWI, etc. (Though I do realize Canada was present)
I guess really it's just because Canadians have the appearance of being nice which makes the country look mostly harmless, somehow making it fun to poke fun at.
But I wasn't saying it's good or right to generalize people of a country, you really shouldn't since, generally speaking, people are mostly the same. As for the gun laws, it's written into our very constitution and is one of America's sacred freedoms. You see, the idea is that the government must be ruled by the people, and must fear the people: "Power to the people". And when push comes to shove, the people have to be able to stand. So we have guns.
@Eagle1Division2 That doesn't change the fact that there are more violent murders, often connected to racism, in the united states, often which are written off as "self defense" and the murderer is not jailed. In my opinion, all countries should have gun laws like japan. You will notice that basically nobody gets shot there, ever, because guns are restricted.
@nOObsBePwnd You're ignoring culture and socio-economic environment and looking only at gun laws. That doesn't work. Let's stay on Western nations with similar culture and economic situation.
Here's a quote fer ya:
"However, the homicide rate in handgun-banning Luxembourg is much higher than in the others: 2.1 per 100,000 population, versus 1.2 and 1.1 per 100,000 for "handgun-ridden" Israel and Switzerland--which have the lowest homicide rates of all."
The vast majority of Middle-Eastern countries, and has a huge terror rate. Fact is allowing people to carry concealed weapons allows them to defend themselves, and make criminals more scared to attack someone that they know can fight back.
Look at college campuses, for instance. Great places for huge multi-murder shootouts because nobody can carry guns! Or the relatively recent shootout in India which lasted days because nobody could fight back!
@nOObsBePwnd Anyways, I think it's sick that most countries have gun regulations in these days. Throughout all of history, whenever people have the right to arm themselves, they are free. It is peasants, slaves and oppressed classes only who don't have a right to arm/protect themselves, through all of history that's true. It's the first and most important step to ruling any nation with tyranny, ask the ancient Chinese, Soviet Union, or Nazi Germany.
@Eagle1Division2 Countries have gun regulations so people don't go murder innocent people, or steal, rape, or threaten other people. If you want a revolution, you will find the guns illegally. And regardless, most of the successful revolutions in the past 50 years have been largely nonviolent. (india, egypt, tunisia, The United Soviet Socialist Republic)
@nOObsBePwnd How do gun regulations stop that? Guns don't kill people, people kill people. Guns are just something people use to do it. Sure, criminals will always have guns, you're right, but that only means that innocent people won't be able to defend themselves against criminals in shootouts OR a bad government. That point works AGAINST banning guns.
And those revolutions only worked because those were weak dictators and didn't attack the protesters. In most nations, they would have.
@Eagle1Division2 actualy, those revolutions worked because the army didnt want to shoot its citizens, many of which were most likely friends or family of the soldiers. Mubarak ordered everyone to be shot, but the army didn't fire a shot. People were shot in india, many of them, but never once did they fire back. and they still won.
#1) None of these shootouts would happen if people had guns, that guns don't cause crime (They don't whisper "kill kill kill" into your ear), in fact they'd probably scare criminals from doing crime
#2) Gun laws are not even a question because owning guns is a constitutional right that is the foundation for Freedom as it's known in America, and
#3) that gun laws only stop LAW-ABIDING CITIZENS from carrying guns, criminals and rulers can still find them.
Great video, breaks down all the basic to more advanced staged of this. I have been wanting to get into RC modle Jets and learning how this all works helps alot. Thanks. IC.
@ShootAllQueers - Fuel is deliverd in a fine spray into the combustion chamber where it mixes with air delivered from the compresor. The mix is lit during the engine start cycle by two igniter plugs, the plugs are then de-energised once the engine is running, the flame then stays lit as its being constantly supplied with fuel.
@lilladojon - Not quite, fighter aircraft use low bypass turbofans, turbo jets are rarely used these days.
@ShootAllQueers its basically a diesel engine, high pressure and fuel auto ignite in the combustion chamber at a specific pressure and temp, pressure is created by the intake blades.
@ShootAllQueers Yes, because compressing the air makes its temperature rise. But jet engines use igniters to light the fuel because their isn't enough pressure during the startup sequence for the fuel to auto ignite. Once the engine is lit though, the air coming out of the compressor can reach 1000 degrees before it even combusts.
Most commercial aircrafts start their engines using pressurized air, not electrics. The APU have an electric starter and when it's running it supplies air to the main engine starters.
Fighter jets use turbojets not turbofans, because of the size.
@zalux you could power them electrically at the start like the car. I believe airplanes have a rather big electric generator that could provide the starter kick. Hope it helps :)
Great question xarlz159! it actually starts with an electric starter motor. Before the invention of jet engines it was manually started with a crank for the propellor but now it is primarily starter engines that do it.
Wow!!! very good explanation, Turbine engines are undisputed!!! No 2 stroke or 4 stroke machines can match....I heard about English and Germans about inventions of this engines, but not Japanese!!! Japanese are the most intelligent pple, I think they too have played a bigger role in these engines.
@MrSaqib140 I often work in Japan and have at times had Japanese people working for me. Although I agree that Japan has some very intelligent people I have to tell you that most are nor very intelligent. I have informed my employeer that I will refuse to use any Japanese people on my jobs in the future due to the average Japanese worker to be not very intelligent.

What thing ignites the fuel there in the combustion chamber? Can you please explain? Is it just the high compression of the air or something like spark plugs in a petrol IC engine? I am an automobile engineering student and i am very much interested in different types of engines. I really found this video very helpful. I now know more than most of the people around me, thanks to the video.

I understand everything but get a little stuck when it comes to the rotor and stator blades. I don't see where the stator blades are and would kind of prefer a better explanation on how this compresses the air.
LittleBigFran 10 months ago
@LittleBigFran The amount of air that the compressor can take is determinate by the air inlet duct.You can see that the stages are big at the beginning and getting smaller at the end of the compressor.So as the same amount of air is passing through the stages and the space is getting smaller the air pressure is getting higher.
(a row of rotor+stator blades=stage)Hope this helps

@SpaceMarine1986 Americans don't hate Canadians... It's just the country is kinda fun to poke fun at. Why? The country is so much like America, relatively new, no long epic history stretching thousands of years... And yet wasn't a key player in WWII, Vietnam, WWI, etc. (Though I do realize Canada was present)
I guess really it's just because Canadians have the appearance of being nice which makes the country look mostly harmless, somehow making it fun to poke fun at.

@nOObsBePwnd lol, that's Alabama.
But I wasn't saying it's good or right to generalize people of a country, you really shouldn't since, generally speaking, people are mostly the same. As for the gun laws, it's written into our very constitution and is one of America's sacred freedoms. You see, the idea is that the government must be ruled by the people, and must fear the people: "Power to the people". And when push comes to shove, the people have to be able to stand. So we have guns.
Eagle1Division2 9 months ago
@Eagle1Division2 That doesn't change the fact that there are more violent murders, often connected to racism, in the united states, often which are written off as "self defense" and the murderer is not jailed. In my opinion, all countries should have gun laws like japan. You will notice that basically nobody gets shot there, ever, because guns are restricted.
nOObsBePwnd 9 months ago
@nOObsBePwnd You're ignoring culture and socio-economic environment and looking only at gun laws. That doesn't work. Let's stay on Western nations with similar culture and economic situation.
Here's a quote fer ya:
"However, the homicide rate in handgun-banning Luxembourg is much higher than in the others: 2.1 per 100,000 population, versus 1.2 and 1.1 per 100,000 for "handgun-ridden" Israel and Switzerland--which have the lowest homicide rates of all."

The vast majority of Middle-Eastern countries, and has a huge terror rate. Fact is allowing people to carry concealed weapons allows them to defend themselves, and make criminals more scared to attack someone that they know can fight back.
Look at college campuses, for instance. Great places for huge multi-murder shootouts because nobody can carry guns! Or the relatively recent shootout in India which lasted days because nobody could fight back!

@Eagle1Division2 What does this thread have to do with how jet engines work?
leoray1234 9 months ago
@nOObsBePwnd Anyways, I think it's sick that most countries have gun regulations in these days. Throughout all of history, whenever people have the right to arm themselves, they are free. It is peasants, slaves and oppressed classes only who don't have a right to arm/protect themselves, through all of history that's true. It's the first and most important step to ruling any nation with tyranny, ask the ancient Chinese, Soviet Union, or Nazi Germany.
Eagle1Division2 9 months ago
@Eagle1Division2 Countries have gun regulations so people don't go murder innocent people, or steal, rape, or threaten other people. If you want a revolution, you will find the guns illegally. And regardless, most of the successful revolutions in the past 50 years have been largely nonviolent. (india, egypt, tunisia, The United Soviet Socialist Republic)
nOObsBePwnd 9 months ago
@nOObsBePwnd How do gun regulations stop that? Guns don't kill people, people kill people. Guns are just something people use to do it. Sure, criminals will always have guns, you're right, but that only means that innocent people won't be able to defend themselves against criminals in shootouts OR a bad government. That point works AGAINST banning guns.
And those revolutions only worked because those were weak dictators and didn't attack the protesters. In most nations, they would have.
Eagle1Division2 9 months ago
@Eagle1Division2 actualy, those revolutions worked because the army didnt want to shoot its citizens, many of which were most likely friends or family of the soldiers. Mubarak ordered everyone to be shot, but the army didn't fire a shot. People were shot in india, many of them, but never once did they fire back. and they still won.
nOObsBePwnd 9 months ago
Why don't people seem to understand that
#1) None of these shootouts would happen if people had guns, that guns don't cause crime (They don't whisper "kill kill kill" into your ear), in fact they'd probably scare criminals from doing crime
#2) Gun laws are not even a question because owning guns is a constitutional right that is the foundation for Freedom as it's known in America, and
#3) that gun laws only stop LAW-ABIDING CITIZENS from carrying guns, criminals and rulers can still find them.

@ShootAllQueers - Fuel is deliverd in a fine spray into the combustion chamber where it mixes with air delivered from the compresor. The mix is lit during the engine start cycle by two igniter plugs, the plugs are then de-energised once the engine is running, the flame then stays lit as its being constantly supplied with fuel.
@lilladojon - Not quite, fighter aircraft use low bypass turbofans, turbo jets are rarely used these days.

ShootAllQueers 11 months ago
@ShootAllQueers its basically a diesel engine, high pressure and fuel auto ignite in the combustion chamber at a specific pressure and temp, pressure is created by the intake blades.
jaydubsteppin 11 months ago
@ShootAllQueers highpressure can ignite fuel?!
ShootAllQueers 11 months ago
@ShootAllQueers Yes, because compressing the air makes its temperature rise. But jet engines use igniters to light the fuel because their isn't enough pressure during the startup sequence for the fuel to auto ignite. Once the engine is lit though, the air coming out of the compressor can reach 1000 degrees before it even combusts.

@ShootAllQueers if you think thats nuts look up how a pulse jet and ram jet work these were the first jet engines ever
in the case of a ramjet there are NO moving parts and compression is done with airspeed alone
Elios0000 10 months ago
Most commercial aircrafts start their engines using pressurized air, not electrics. The APU have an electric starter and when it's running it supplies air to the main engine starters.
Fighter jets use turbojets not turbofans, because of the size.

@s87343jim Because turbofans are more efficient than turbojets. They produce more thrust and use less fuel than an equal diameter tubojet engine.

Great question xarlz159! it actually starts with an electric starter motor. Before the invention of jet engines it was manually started with a crank for the propellor but now it is primarily starter engines that do it.
