Couple of gripes with this comment, first of all ge9x is only for upcoming 777x not 787, they have produced a maximum thrust of 134,300 lbf but will only have a commercial thrust of 105,000 lbf so less than the predecessor ge90 , and both of them produce 210,000 lbf while 747 240,000- 266,000 lbf which I wouldn't consider close
@Von Fart I’m glad you said something because I was like “I never worked on the 777-200, 200ER, 300, 300ER, -8/9, or 787 but I can tell you the engines on each one and they certainly aren’t all GE9X engines”.
In my 30+ years of airline maintenance I've changed just a few engines. Then again I've also changed a few in the military. In the airline business it's nice when you ave a hangar to work in, but that's not always the case. I've changed them outside in the blistering heat, and also in the freezing cold & snow having a hangar to work in is a luxury. FLY NAVY!!!
@@UltraMagaFan I agree with your comments 100%. I am a US Navy Veteran and Jet Mechanic. Engine and Propulsion. I also changed engines in the hanger deck. The video you saw showing the engine shop is called AIMD.
@@UltraMagaFan AIMD means Aviation Intermediate Maintenance Depot. In other words they take the Engine completely apart and fix it. US Navy Carries are designed to do this process. I was assigned to work in that department a couple of times.

Another mind boggling thing that usually never gets explained is before the engine and parts are produced, every tool, press, dies and other specialty items need to be designed and made from raw materials…from tooling that will make something that it itself can not do! Incredible!

so true and correct. and the paper trail is crucial when there is a quality escape, everything is traceable and root cause is within reach. We relied on overhaul documentation more than I can remember. Compare that to classified document tracking today, sad!

2:32, lmaoo I wish I, as an aircraft mechanic, had the luxury of changing engine with a hangar. In my old job, we had to change a 767 engine twice a week, OUTSIDE, IN THE RAIN, WIND, STORMS, AND THE COLD. EVERY. WEEK.
As technologically advanced as these engines are. The thing that is truly astounding is the astronomical amount of fuel each and every one of these monster engines consume every minute they are operating. When you consider the fact that tens of thousands of civilian and military jet engines are running all over the world every single second of the day - its truly mind boggling how the oil companies can drill, refine and transport 100 billion gallons of this fuel each year just to meet the needs of the aircraft industry alone. Thats about 275 million gallons of jet fuel consumed each and every day. That is a staggering amount of refined kerosene thats needed just to meet average daily consumption!
@dhouse considering the very detailed response you gave I thought it was quite a funny contrast. the argument is not lost on me completely though but the airline industry is driven by consumer demand.
When you compare the fuel used on a modern jetliner like the 777 against the amount of work that can be accomplished, it’s not a bad compromise. If compared to doing that with another mode of transportation in a given time span. Fuel cost per passenger per mile for example, many modern jets put up a good number, or the immense amount of cargo a 777 can carry, which is 100 tons with a range of 9,200 km. (A Boeing 767 only 50 tons). Yes it burns a lot of fuel, but to move that cargo by other means in a timely manner, what do the alternatives require.
Amazingly all of these engines are built by hand, seen a Rolls Royce documentary recently and it showed a small number of engineers/fitters building each engine all by hand no robots in sight
Brother was senior exec vice president at delta. In charge of ALL maintenance at one time. Till he got promoted. Never asked him once about tech stuff. He retired. At 54. To count his millions.
I think it's great that Those Who Invented the Jet Engines. Firstly, it provides enormous momentum and secondly, the relevant aircraft will fly to A and B like a rocket. A Very Great Piece of Engineering from these Inventors .
I wonder if area critters like squirrels and bunnies develop tinnitus from hanging out in the woods around airports. I would totally move, especially if I was a bunny with big, floppy ears. The least we could do is provide them with free hearing protection.
3-7 hours still beat my certified mechanic charged me for a water pump and timing belt replacement. It took him 2 hours but still charges full 4 hours and managed to left the screws and engine mount loose.
In the old days, when Boeing 727 & DC-9 aircraft were very common, some facilities did not use cranes, but instead had gantries which could be closed in around the rear of aircraft to permit engine removal or servicing. The upper deck would be 45 feet tall.
Fan blades are look solid but are in fact honeycombed to make them lightweight but extremely strong and they are made out of titanium. each blade will be the cost of a small family hatchback.
Frankly speaking, the engineering involved in making these aero - turbines is complex and mind bonging. Repair and maintenance routine check up needs more skill.
Me agrada la aviónica, pero lo que más me desagrada es toparme con personas que pretenden introducirse en canales de habla hispana, pero hablando en inglés, sin haber aprendido antes un mínimo de educación y respeto .
I see that with many of these newer engines, such as the GEnx, modular is the big thing... If the problem is in the fan, turbine, compressor, etc. you just remove that particular module section and swap it out for a new one instead of a whole engine... Cuts a lot of down time...
Parts have different life cycles, mainly flying hours. For an ECU or power plant, the engine is changed at the end of the life of the lowest life component. Some components can be on calendar life and others are on condition.
Perhaps your writer wanted to say that High Bypass Turbofans for airliners did not arrive until the 1970s with the introduction of the wide-body airliners like the 747. Turbofans were introduced for airliners just a few years after the Boing 707 first flew commercially. Those were low bypass turbofans in the late 1950s jetliners that were in use, and for a very good reason; fuel economics. Also the first airliners that used the turbojet engines were both smoky and very noisy on take-off. I was an ear and eye witness to the first flight of the Convair 880 in San Diego so I can attest to to that. Those aircraft used water injection systems (the dark smoke) which cost them the weight of some seats they could sell, and even those earlier, lower bypass turbofans were much more fuel efficient and a bit quieter.
Even more to the "Game Changer" point, by Aviation standards, Reliability trumps over Power or added range. Jet Turbines are Much more reliable than Reciprocating Engines. Parts rotate in a Jet vs the mix of back & forth linked to round & round parts in a Recip that must all be timed to run together. I worked for a U.S. Major commercial air carrier for 3+ decades, first as a mech, then into maint Inspection and finally in the Propulsion Shop (we flew Jets & Turboprops). That said, like many I've met in the industry who really enjoy Airplanes, I've built/flown every type of model Radio Control aircraft there is to fly. I started w/ recip R/C Helicopters (up to a competition level), eventually moved into fixed wing, gliders and then 1/4 Scale. Where I'm going w/ this is that as much as I love my Recip powered A/C & Heli's, the Electrics have taken over as the most reliable w/ the least maint. I have made it a point to learn, troubleshoot and make my Methanol powered recips as reliable as possible thru preventative maint and good care, but the Electrics win every time when it comes to Reliability And Power to Weight (wing loading). If the power density & safety issues w/ batteries can be overcome & made to fit commercial aviation, Electric engines will replace Jets & Recips for their simplicity and Reliability. I think that day isn't too far off.
Seriously on your claim the jet age (military, or otherwise) didn't fully take over until the 1970's Wow... You all fairly accurate but absolutely got it wrong claiming the 70's was it...
What with the pounds? Can’t you use tonnes or kilograms? Honestly, and no offense Americans, it’s only the U.S., Liberia and Myanmar that officially (still) uses the imperial system on the whole planet. Get up to date.
O.K I get it , the world's most powerful jet engine ..........( yawn )......but it is not a rolls-royce , is it ? " a previously repaired engine is brought in " ....really ? at 30,000 feet I like to look out of the window and gaze at the ...RR...symbol , not think about how well the previous repair was ,
The precision engineering required to produce these engines is mind boggling for normal folks such as myself.

Wouldnt the engines just be cleaned when they fly through clouds or rain...
No because the air is very dirty.Its full of dust.The engines had to be cleaned for efficiency and longevity.

Surely, squirting so much water into the main engine is likely to cause short cirquit problems which will affect the spark plugs?
Spraying water into a air pump? Really? That's all an engine is. It's hydrolocked
