GTF engine: Game-changing efficiency and sustainability | Paris Air Show

[@natwarkedia]

It's groundbreaking ability to keep planes grounded makes this so different.

[@cnordegren]

At least you know about this issue and PW is NOT making excuses...unlike Boeing.

spot ON. at least this mess of an engine didn't kill any Go First Airline PASSENGERS.

[@greenesyt563]

Go for CFM-leap much better than this sh*t.

[@josealbertocastellano2951]

Very good Engine, although everybody thought that it was going to be the Fan Gearbox the one will cause trouble, it has been performing extremely well. Hopefully, P&W fixes the teething issues very soon with upcoming upgrades

[@mrunning10]

"Teething?" You're kidding?? Hope they fix the fucking SAFETY issues. Better continue to hope it don't BLOW UP like the oil seal problem in its PW1500G spewing pieces all over the ramp in Mirabel, or the high compressor knife-edge HCF in the PW1100G, or the one-pipe-out cooling of the high turbine, or why most of the thrust load on that big fan is carried by only TWO of the planetary gears, or the highest RPM turbine in the world working right on the edge of material limits ("certified" like an engine from 30 years ago). Just wait a bit longer for the NEXT failure and hope that "performing extremely well" doesn't equate to deaths.

[@MilesEdgeworth129]

They have certainly learned from the shortcomings of the PW1000G, that's for sure.

[@michaeld5888]

The phrase 'Game Changing' leads to many outcomes not always positive. Performing well but with teething problems which will 'hopefully' be fixed. If you know they are teething problems why the need for hope? How does that combination hang together? Putting a gearbox in to what was a reliable power source because of its essential mechanical simplicity is a whole new world. A constant speed propellor in a turboprop has extra benefits with the jet engine not needing to spool up with the re-stabilisation of gas flow for extra power. But putting in a gearbox just for more optimised bypass is entering the realms of trading safety for cost efficiency.

[@MilesEdgeworth129]

@@michaeld5888 And you think the technology can't improve to compensate for the shortcomings? You think engineers don't learn from their mistakes? I'm pretty sure P&W has been taking a good, long, hard look at the data of previous PW1000G failures to determine the cause of each failure, and work to address them.

[@Roboseal2]

@@mrunning10 Stop complaining. I do agree with the marketing shit though. You do realize other engine manufacturers have problems too huh? Sounds like someone got fired or just doesn't like a good (but maybe slightly corrupt) company.

Sad , they’re powerful, quiet , and very efficient engines , hope they repair those issues soon , ✈️ I remember when the A320 first came out with the V2500-1 has so many problems too 🤗 Nowadays they’re in the series 5 and they’re very reliable . Happy landings everyone

Ground breaking engine so good planes spend more time on the ground

[@vamsavardhanavijay5532]

Lol

[@Deming91]

The PW1000 series engines are incredible, powerful and silent!! Have rode both the A320 Ceo and A321 Neo (powered by the PW1133G), & you can feel the immense power of the GTF engines pushing you back into the seats!! Impressive performance, and the massive fan blades also looks amazing.

[@mrunning10]

Wow! And you survived!!

[@joe-p9k4n]

Silent because they are sitting parked on the ground. And in flight they are quieter than the CEO but they have a low frequency hum that can not be synchronized with autothrust. Autothrust has to be switched off and engines synchronized manually. Waaahhhh......waaaahhhhh.......waaaahhhhh....

[@mrunning10]

OK, your first sentence is spot on. The remainder is wanker I don't know shit commenting. I guess you're TRYING to make a sarcastic joke. @@joe-p9k4n

[@BuzzLightyear66]

It's very helpful that Pratt and Whitney have mass-produced these cleaner engines. Replacing older aircrafts with those powered by these engines will absolutely reduce the carbon footprint of air travel.

[@Mike-jv8bv]

nobody cares about the global warming scam.

[@cnordegren]

I have flown a A320neo (with GTF of course) and the cabin is crazy quiet! I loved the experience and will look forward to flying airlines with Neos (with GTF) again! Pratt & Whitney WILL solve their issues with GTF and we will be happy flying the Neos.

[@mrunning10]

Of course it's a great engine, when it ain't sitting on the ground you dumbshit. The ISSUE is the problems that PW KNEW were there BEFORE Certification and yet the FAA Certified this Piece of Shit anyway.

[@steffanjansenvanvuuren3257]

Turbine Helicopters use the exact same mechanical principle. High speed low torque turbine engine into low torque input but Hight torque output low speed gear box. It just makes sense.

@@mrunning10 You think engineers don't learn from their mistakes? I'm sure P&W has taken a good, long, hard look at the data of previous geared turbofan failures, particularly with the PW1000G, and are looking to fix the root cause of those issues by building this new engine, the GTF, from the ground up.

[@eduardodaquiljr9637]

Do you have also engine similar to GTF you are explaining fit for wide body planes?

Nope, Pratt tried, the GTF does not scale up. Think of the weight of that big fan gearbox getting bigger and bigger.

[@briankamerath338]

I'm immensely curious about prospects of scaling for the GTF family. Are there planes to go larger...smaller? It's not hard to imagine military applications as well. I want to see how this plays out. I'm a bit shocked that domestic brands aren't, as yet, adopting this.

[@vamsavardhanavijay5532]

Probably because the airline that trusted P&W are now headed to bankruptcy in India

[@mrunning10]

The director in marketing said in a sentence something strange like "So because this engine offers such a low reduction in fuel about 20%..." I gather from the his first part that he says that this engine offers a very low reduction in efficiency, what means that is very bad. Later he says 20% less. But the start Low Reduction sounds they did a terribly job.

[@mrunning10]

​@@Nosferatu295 Ahh, excellent. I analyzed the certification compliance to the Type Certificate. It shouldn't need "fixing" if it were designed correctly. All is good for now, until that fan gear comes apart due to asymmetric loading (Pratt "thinks this will be contained) or the turbine blows up like the kinetic bomb that it is because it's the fastest high spool ever flown and lives right on the virtual edge of material properties and the FAA skimmed right over 14 CFR 33.29 (and PW didn't complain about this because the KNEW the engine did not comply (will be an un-containment, KABOOM). All known by Pratt & Whitney and NOT openly communicated to the FAA during Certification of this engine. (h) The applicant must provide instrumentation enabling the flight crew to monitor the functioning of the turbine cooling system unless appropriate inspections are published in the relevant manuals and evidence shows that: (1) Other existing instrumentation provides adequate warning of failure or impending failure; (2) Failure of the cooling system would not lead to hazardous engine effects before detection; or (3) The probability of failure of the cooling system is extremely remote. --> incorrect number given to the FAA for certification. ​ Captain "Joe" is just a horseshit salesman and YOU are "fixing" and engine that is un-safe per the CFRs.

The issue with the GTF leads me to think that most of the large American Engineering companies are now being run by suits, instead of Engineers

[@mrunning10]

Nope, run by "50% gender parity" by 2020. (direct at the time from David Hess in the Gold Building) NOTHING to do with ENGINEERING. If a company focuses on SHIT you get a SHIT engine. Here's another direct quote from a PW Manager ( a Fellow !!) at the time: "...she's new to this but I guess she'll pick it up over time..." when yet another "gender parity" Manager dropped down like bats in the belfry. Hiring people and placing them in positions of decision with NO fucking EXPERIENCE.
