Former Boeing Everett Commercial Division here... I have been up close and personal with the GE 90 Turbofan Engine used on the Triple Seven (777). I tell people the letters and numbers on Engine have a special meaning: G = Gigantic E = Engine 9 = 9 feet diameter Front Fan. I have stood inside main inlet and GE 90 with cowling is so big it wouldn't fit inside my house. It would be sticking up through attic and past roof. The 2 Engines used on 777 have a much power as the 4 engines on the 747. That translates to exceptional performance when needed. In case of engine failure, a 777 can fly across the ocean on a single engine safely. The Engines are the most expensive single part of aircraft. That is why Boeing uses 'Just In Time' inventory control. If Engines are needed on Wednesday, they arrive on Tuesday and are staged to be installed on Wednesday. No use having expensive engines sitting around a month before needed. They cost millions of dollars and Boeing uses lots of engines.
@@WhiskeyGulf71 I think that is when the burners are lit and pressure is built inside the combustion chamber, maybe the high/low pressure turbines? I've been also looking for the proper term, if there is.
@@WhiskeyGulf71 the low pitched sound is the ignition of the fuel when the engine igniters are lit. When a jet engine starts, there's a sequence to its operation. First there's an air starter that forces air through the combustion chamber to help spool the engine up to its required RPM. Another device that helps is the accessory gearbox that makes the blades spin right as the air starter engages. Then once the engine is up to speed, the fuel injectors start putting fuel into the engine and the igniters are lit, then there's fuel ignition. And then you have a running jet engine.
Outstanding video. When he slammed the throttle to max I could almost hear Joe Patroni from the 1970 movie, "Airport." yelling, "Hang on, we're going for broke!" ✈
AWESOME VIDEO, AND AN AWESOME RESPONSIBILITY FOR THE MEN AND WOAMEN WORKING ON THESE ENGINES, THANK-YOU ALL SO MUCH. BOY O BOY WHAT A COMPLEX ENGINE !!
Whow, I just discovered your channel. What a wonderfull video. And a friends daugther is now working in the Engine department of KLM who use GE I think.
After the NIMROD RR engine (i forget the designation) backyard guy in the UK, I was worried this would be done in some shed somewhere in England. Good to see it being done properly lol
What ? 18 minutes of waffle before the engine start is already under way. very disappointing and I regret selecting on this item. A better title might be - "An agents discussion about the engine with a bonus engine start after 18 minutes"
It's only 15,000ft lbs more than a Trent XWB 97 so what's the big deal here? May aswell strap a JT3D to a Trent XWB because that's all you get over it, literally.
Price of a GE90-115B = $27.5 million USD... Cost of a RR Trent XWB-97 = $35 million USD + the cost of strapping a P&W JT3D-1 to it... So yeah, you could do that if you didn't care about money.
@@Amehdion Price and application vary Trent XWB is far newer and lighter and uses more advanced materials and triple shaft architecture unlike the GE-90 which is a giant CF-6 with more stages.
@@lukekeylock2935 ehh, sorta. weight difference is 3,000 lbs and the GE90 ends up with a higher TWR. The "more advanced materials" thing is a moot point, the GE90 is packed with advanced composites even being the first engine to have composite primary fan blades. In the end, I'm not here to argue about which engine is better, they are both pretty impressive. I was just saying that there are reasons why you might choose one over the other, cost being a big one.

That deep roar as the engine comes to life is priceless

The Most AWESOME Aviation engine on the PLANET.....Thanks GE!!!! 🇺🇸🇺🇸🇺🇸
im surprised that whole building didn't take off. my goodness
What you can't see in the video is that the earth started rotating a bit faster actually.
@@YankeeTango748 lmaooo
@@YankeeTango748 Actually - shifted from orbit/path - as I think the test cell exhausts upwards

Wow 😂😂

17:49. Start up

I just watched that video a RR Spey scorching some grass lol
It was nice to see Chuck Norris narrating.
So powerful they create their own weather
Wait, what?
This actually true. Outdoors, you can see condensation ‘appear’ from nowhere - at the intake area.
We need this kind of video of the PW2000
I love the buzzsaw sound 🥰
17:50 engine startup. full power test start up 23:01
Such a beast of an engine ever.
Thanks Big Jet! Found the whole thing very interesting.
18:47 moooooooo
Cheers for this video, very interesting.

My PC: 25:06
You didn't record the engine shutdown... So sad!😭
Reminds me of those pod racers from Star Wars Episode I.
Could anyone explain to me why there is such a impressive roar during the startup? I almost feel like i listen to a Pulsejet.
At about 9% n2 speed fuel is introduced into the combustion chamber, that is the boom and roar usually heard
THATS THE ENGINE FIRING OFF WITH THE INTRODUCTION OF FUEL
2,000,000 cubic feet of air per minute goes through that engine at full throttle
I hear the GE90 howl at Boston Logan Airport every day.
Super awesome engine sounds
He's like "Where does the fuel come from?" and then at 26:18 I mean ahahah
How does the building behind the jet contain the thrust when it's going full power?
This is how they test ducttape
Wish we could see the Dyno numbers

I wonder what Sir Frank Whittle would make of these now

After giving full thrust, it sounds its losing power second by second.....

This Turbofan Engine Starting of high Voltage Electricity?
Nope - would be a separate, smaller compressor (which, yes, I think is electrically powered)
