Hypnotic Process of Repairing World’s Most Powerful Jet Engines Ever Made

[@johndeluna692]

The precision engineering required to produce these engines is mind boggling for normal folks such as myself.

[@ArifGhostwriter]

I don't think it's a million miles off the level of precision & accuracy needed for making modern car engines - it's just the context & use that makes it seem more amazing (car engines are mundane).

It’s amazing how balanced the fan blades remain when in use, even when exposed to vibrations, high temperature and stress these components are under. And there’s literally no wiggle room when it comes to tolerances. Trippy

The current jet engines are miracles of technology.

[@SJR_Media_Group]

*_Former Boeing Everett. I have been up close and personal with GE9x Mega Turbofans._* Front main fan is 12 feet in diameter and won't fit inside most houses. It would stick out through the attic and roof. Standing in front of one of these massive jet engines is an awe inspiring experience. It's used on 777 and 787 aircraft. These engines can produce125,000 pounds of thrust, enough for a single engine to lift aircraft and make emergency return to airport if other engine quits. It has more than enough power to take it across open water to nearest airport in case of emergency. *_2 of the GE9x's have almost as much power as the 4 smaller ones used on 747._*

[@alexandrosandreou8585]

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

[@zakp.2759]

The narration is like talking to a 10 year old. The engine must be maintained! Each part must work properly with the engine! Each engine has to be tested! WOW.

[@timrussell1559]

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!

[@GNX157]

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.

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]

[@vicentetroyhunt4980]

@@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.

[@vicentetroyhunt4980]

@@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.

[@UltraMagaFan]

@@vicentetroyhunt4980 If I'm not mistaken, there is even a facility on board, at the aft of the ship, where they can test jet engines out of an aircraft at full throttle and full after burner. It's basically a hush house without the sound deadening. American aircraft carriers are self sustaining. They are able to keep their squadrons flying for long periods of time without going to shore. It's impressive.

[@justwantresults8768]

@@vicentetroyhunt4980 "Intermediate maintenance" and "depot" are conflicting terms. Doesn't USN just do module swaps on carriers and the module heavy maintenance is done at the depots stateside (or wherever).

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...

[@paulgracey4697]

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.

[@justwantresults8768]

I would agree, true high bypass engines came in that era via the JT9D, CF6 and RB-211

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.
