finally mystery solved..

The Airbus 380 is claimed to carry about 82,000 thousand gallons of "Jet A" or JP5 fuel, (manufacturer specs.) This Jet A is weighing in at 6.8 lbs. per gallon, that's 557,600 pounds of fuel divided over 10 fuel tanks. The 10 fuel tanks must carry 55,760 lbs. a piece (tail tank smaller)! If each wing has at least 4 tanks full, that's about 223,040 lbs. of fuel alone, inside each wing (ya sure) with no Center Tanks at all. When you try to calculate how many Airline Flights are occurring each day, from any International Airport, you'll realize there is no local "Fuel Tank Farm" that's being constantly resupplied by a fleet of Fuel Tanker Trucks trying to get into the "Fuel Farms" here is an example of the size of these Fuel Farms www.flystl.com/newsroom/stl-n..., you can do the math, lol. skymarkrefuelers.com/products/ their biggest Airline Tanker is only 10,000 gallons! So it would take 8 of this type of Tanker to fill the A380 just once! LOL ... Commercial Airlines and Military Jets are started by the (APU) Auxiliary Power Unit (Aircraft Engine Starting-Wiki) en.wikipedia.org/wiki/Aircraf... and run on compressed Air, it's Viktor Schauberger Turbine Technology www.antigravitytechnology.net/... but this is a Trade Secret and they'll never admit it. People would feel cheated, and demand refunds and we'd start asking questions about the 9/11 Event fireballs etc.

The engine bleed air system uses air from the compressor 10th stage, not bypass air or 14th stage. At least on TF-34 type engines.... Only error I caught on first viewing.

Excellent explanation. I pretty much understood what takes place after start but I always wondered how it got to that stage. Thanks

Nice job on the way a jet turbine works but, I have a small problem, starting at the front of the engine. First the fan/single stage with air going down the low bypass duct/cold stream duct (can have other names). The fan is also connected to the N1/low pressure compressor connected by a long turbine shaft and connected to the low speed turbine (3 turbine wheels/disks). The forward part of the engine or core has an inlet just like the front of the inlet of the engine. The core inlet normally called the cold section houses N1/low speed compressor which is connected to low pressure turbine, alone with the N2 compressor that is connected to the high speed turbine (2 wheels/disks). The Hot combustion section is next with combustion can or cans, spark ignitors, fuel nozzles then out the exhaust vanes and turbine wheels. many types of jets, turbojets, turbofans turboprops and all have other names for the same parts / RR GE PW As an old pilot with 30 plus engines and 20 plus A/C.

How not to blink while starting a jet engine.

When an aircraft is parked, the power generation is given by an external cable connected to the airport, which is kinda obvious. You can see it while boarding the plane, it is connected below the cockpit area. but just wanted to give this little hint about the movement inside the cockpit. you can actually see when the crew disconnects the external power and becomes independent from the airport. watch the lights blink inside the cabin, just once. The APU is now the main power source. This is a sign that we're rolling in a few minutes (if you're not flying Ryanair, our very own bus with wings) anyways, i have a lot of time on my hands

Umm I always thought the external compress air is use to start up the APU and the APU bleed air is use to start the main engine, but what do I know.

So now it's running, how is it stationary? Is there a transmission like a car, or is it just running slowly? I wanted to know how you got the thing off the ground, more or less.

And here I was thinking that 'turbans' were a kind of Indian and/or near/middle eastern headwear! When I received my various degrees in the sciences turbojet engines, and their derivatives, employed a system of *_turbines_* to control and maintain the various pressure zones. I'm truly fascinated to discover the principles behind this alternative 'turban technology'.

Bill Lear was getting ready to take off at Southern Illinois University's airfield years ago. But the ignitor wouldn't work on one of his engines. So he lit it off by tossing a burning handkerchief into its tailpipe. Much less complex. And he didn't say "aww", not even once.

Many other RUvid presenters should watch this to learn how to give clear and precise information. There are too many RUvidrs who can’t talk their way out of a paper bag.

Why does the presenter wiggling around while he's talking? He's head keeps tilting back and forth and his shoulders keep shifting around. The only time they stop is when his mouth stops. Weird to watch.

Bob Rice
Bob Rice Month ago
So you show an auto start. It would be more informative to do a manual start. Crank the hp section with the start motor via the GEARBOX, watch for 25%N2, open the hp cock, which adds fuel and starts the igniters. Watch the EGT doesn’t overtake the N2 speed or you will get a hot start. That’s giving the wrong impression. And it’s an air start unit!
Mark T
Mark T Month ago
@Bob Rice LOL. Yea, I noticed the core identified as "hot section." Well, it's connected to the hot section. J79's were 15% if I recall correctly, but that was a turbojet.....not turbofan. F100 and F110 were 10%. I thought he was referring to the pilot when he mentioned "HP cock." LOL! We called them "Stick Actuators."
Bob Rice
Bob Rice Month ago
@MarkT There’s dumbing down and simplifying to the point of inaccuracy. Since when did the HP compressor become the hot section? The ignition coming in at 15% is rare and I must have missed them opening the fuel HP cock.
Mark T
Mark T Month ago
@Bob Rice I think he was just giving a "layman's" example of a motor start. You sound like a motor head, like me. We've started our fair share of jets. There's a lot more to it than what he's saying. A lot can go wrong if not properly trained.
Bob Rice

Oh and you also have to monitor oil pressure, N1, and time to reach idle.

We started the Pratt Whitney FT4A jet engines on our ship hydraulically. We called it they hydrostart system. I believe at flank speed we burned over 20 gallons a minute on each engine.

If you keep adding fuel to a turbine engine, it will keep running faster and faster until it blows itself up.

Why do commercial pilots always go ERRRRRRR after every second or third word. " Good morning, this is ERRRRRRRRR your Captain speaking ERRRRRR, the weather outside is ERRRRRRR" ............The wings have ERRRRRRR come off and if, ERRRRRRRR, you would like to ERRRRRRR panic, follow me ERRRRRRRR"

They simply have lot to remember and stay on top of, while still trying to be polite to other people they interact with. They’re always having to be debriefed with the latest occupational hardware/software updates. So yea I’m pretty convinced it’s a practical reason for what it is they do while in the cockpit.

Pronounced tur-Byne. Not tur-bin. Turbins are what some people from Indian wear on their heads.
Pete is never wrong
Americans. "Erbs", instead of herbs, "sodder", instead of solder, and "Anarca" instead of Antarctica. And my favourite, Astuter is "Astooter", but computer is not "compooter". English can be problematic for some.

Actually the Fan and Compressor sections are called the cold section where the combustor and turbine (along with augmentor and nozzle) sections are called the hot section.
