Pratt's $10 Billion Bet Stumbles As Buyers Turn to GE Jet Engine

Pratt & Whitney's $10 billion bet on a new jet engine is faltering after a troubled rollout, and buyers are rushing to a General Electric model instead. (www.chicagotribune.com) 更多...

What is odd is how the C-Series, which runs the Pratt GTF had a few stumbles but were fixed pronto...I have a feeling its more of a software issue causing other issues

They did have some stumbles early on.... And so did GE... Look at TACA Air with the GE CFM-34 Dual Flame Out landing dead stick near NASA... I doubt airbus would have faired as well.

Yes sparkie..I remember the TACA landing on that canal jetty (also Mayday did an episode on it)..but what I am saying is, the Pratt on the C-Series isnt much different in design, if any, than that on those Airbus...I've said it before and will continue to say it...I think the software between the Airbus side and Pratt side like having arguments, so to speak, and so do the engineers..the GE LEAP engines aren't much different than modern turbofan engines of today, and so the Airbus software is a happy sod.

Keep on mind that Pratt has decades more experience than any other US engine manufacture... Only other one even close is Rolls Royce as far as what is still around now days.

Barring any major mechanical failures, software in this day and age of FADEC’s can make or break an engines efficacy & success. Most major airframe advancements have been preceded by major engine advancements. Having said that, I am amazed at all the rhetoric about the new technology GTF’s. Does anyone remember the Garrett/AiResearch/AlliedSignal/Honeywell 731 engine from 1972. GTF’s are not new. Every engine manufacture has its own engineering way of doing systems in its engines and it usually follows all the way up through the manufactures line of models. GE engines tend to be more complicated (Swiss watch) in their design whereas Pratt-&-Whitney engines tend to be more simple mechanical designs (Russian Nagoya Tractor Works) but they triple control everything electronically. On any new engine design there is always a fight between what the engine manufacture designed and what the airframe manufacture wants the engine to do. Given time and money it usually works its self out.
Pratt-&-Whitney for many years flew Learjet 36-001 as a test aircraft with a 731 engine on the left side and whatever P&W engine it was testing on the right.
Yes I do remember the R-1830’s. What’s the old saying, “If God had intended man to fly with flat motors, Pratt-&-Whitney would have built one.

Do planes ever fly with different engines?

Pratt on one wing, GE on the other.

No... That would always be unbalanced thrust... Also, usually 1 will compliment the other especially with the FADEC's.. It is either GE, Pratt, or Rolls Royce.

I always like Pratt Engines... Cut my teeth working on the JT8-D's.... And I love the old R-1830's... Any one who does know what an R-1830 is is too young to ask... They have always made great engines and have supported us through many wars!

Working on those 1830's in the cold wasn't fun though...think Northwest Territories wintertime in Canada..lol

One has to learn to let the clutch pedal out slowly. Once mastered, a GTF can be driven, aside from downshifting, even without depression of the clutch pedal.

I think Bombardier must have mastered it then..Airbus is in too much a hurry..lol

Interesting how people were saying a little while back that GE has to develop a geared solution of their own to be competitive.

I don't think the P&W problems in any way invalidate the need for GTFs -- they are more fuel efficient and quieter than traditional turbofans, and we'll see most new jet designs adopt GTF's until they eventually go all-electric.

Teething problems with new technology are nothing new, even the turbofans whose reliability we take for granted today started out having massive problems.
