As a pilot in the right seat of a regional 38 seat turbo prop. I earn less then the guys that put the bags on the plane. Not to mention 140k worth of training, loss of income due to training and years of stress and sims every 6 months. We all do highly specialized jobs. The magic comes from teamwork, not individuals.

@@ibsn87 Sir, you by any means are doing a complex and specialised job. Problem here is that you are also so underpaid. In Europe and Türkiye, my pilot buddies make x10-15 times the lowest salary. Pls transfer yourself to THY :)

@@semihklcgedik7239 regional turbo prop first officer ~50-60k. Zero qualifications- Dump truck operator working 7 on and 7 off in open cut coal is on 120-160k in Aus. Teacher ~75-95k. Cabin crew 55-85k. Baggage handler 55-70k. The world is not fair at times. First officer of a 100 seater Jet ~120k. Even that, is less then a dump truck driver at the mines.

What happens when you loosen a filled party balloons air stopper? That's whqt he's talking about.

So can we considered turbine as a auxiliary machine please let me clear.....

Helium doesn't make balloons move. The rapid decompression forces helium out of the small orifice, generating thrust. You'll get the same effect regardless of which gas you air the balloon up with. The balloon skin expands when you air it up, so if there's an opening for gas to escape, the skin will retract and push the gas out.

Lol

@@sixstanger00 I think OP's confusion was due to concentrated helium (lighter than air) filled balloon makes the balloon go up in the air. However the concept the video is referencing is not that (but when any gas filled pressurized balloon has a sudden leak of air, balloon moves in opposite direction).

The only thing internet explorer and i will not.

First thing I noticed, too.

Isn't that just a propeller aircraft with more steps then?

the flaw here is we see these impressive inventions and forget that this is the result of no less than decades of engineering progress built on top of centuries of math and physics. you probably are smart enough, is what I'm trying to say

It's a collective knowledge by thousands of people rolled into one.Like the Internal combustion engine(ICE) it looks complicated but when you understand how it works it's fairly simple.

It's the product of combined inventions and knowledge. Not a miracle.

Only respect to be given here are his skills at animation. But from the standpoint of a turbine engine mechanic (which I am) all I could think was, dang, animation must be much easier than gathering facts. doesn't he know what google is? I mean really, you don't even have to get out of your recliner to get better info than that.

I noticed this too. I think it's what martin said.

At 4:00 the front rotor blade is going in the correct direction. At 5:00 the rotor is still turning in the right direction, but the animation turned the blades 90 degrees in the wrong direction.

Dennis Edwardz Thanks, yeah. I looked back later, and was having problems seeing what I saw the first time. Didn't really feel like going through all that again :P I have directional dyslexia so I couldn't figure out if i was just confusing myself. When people make mistakes like that, it really fucks my mind over, my brain is suppose to be the source of the inconsistency :P

othman fikri lol I noticed that also, oops lol

othman fikri Came here to say that. High five! :D

They do this so that the engine is stable as well as to keep the air flow smooth. That's why they have the stators and the stator veins.

Valk Stators have nothing to do with keeping the air flow smooth, explain what you are thinking. Stators increase the bite angle of the trailing turbine/compressor veins or blades (whatever you want to call them) so that the air entering the front of the turbine is moving at in an opposite direction, or is at least not turning with the trailing turbine/compressor. This makes the turbine/compressor more effective.

Thad ward That is what I was (kind of) trying to say. I should've said that the stators and stator vanes redirect the airflow as that is what they do.

Chris Bogart Good question, for the starting purpose we have to use an electric motor. The electric motor will run the main shaft until enough air flow is achieved in compressor and combustion chamber. After that the fuel can self ignite and sustain the operation.

Chris Bogart Depends on the engine, usually involves spinning up the HP shaft in some way, then when enough air is going through - engaging the igniters and introducing fuel. The spinning up of the shaft can be done in several ways. Quite a common one is the air turbine starter, which is a small turbine attached to a reduction gearbox, spinning the accessory shaft which attaches to the HP shaft (it drives accessories like the oil pump when the engine is running). You can take that air from the aircraft's APU (which itself has an electric starter), or a ground based starter. On multi engine aircraft, the one running engine can then supply bleed air from one of its compressors to start the other engines. Some engines (as mentioned by the uploader) use electric motors to spin the accessory shaft, and the RR Olympus uses a hydraulic motor. The air turbine starter is generally more popular however as it can provide a lot of power for its size and weight, and it's fairly simple. Another way of starting a gas turbine engine is by direct turbine injection. Injecting air directly into the HP turbine causes the engine to spin up the way it does under normal operation, however it usually requires a greater volume of gas than an air turbine starter, which may be unavailable if the APU isn't big enough (or the ground based air supply). This may be done to save on the weight of the air turbine starter and its gearbox (or an electric starter), but as mentioned above - may be impractical, as it requires either a bigger APU (which would make the aircraft heavier) or a dedicated ground starting gas supply, which makes it dependent on external equipment which may not be at every airport

Learn Engineering Most commercial-airliner applications would overheat a starter electric motor. Usually a "start cart" provides compressed air to an air-turbine starter on the engine's gearbox to give it the spin-up it needs to start. Some planes (all ETOPS-compliant ones among them) can start their engines internally using bleed air or hydraulic pressure from their auxiliary power unit. I've only ever seen one electric-motor starter on a commercial jet engine.
